[Low voltage resistor]SNGR series neutral grounding resistor

SNGR series neutral grounding resistor

��1�� Introduction
The neutral point grounding resistor cabinet is mainly used for connecting the neutral point of the main transformer and the grounding grid in urban and rural distribution networks. The urban and rural distribution network mainly refers to the three voltage levels of 10kV, 35kV, and 66kV power grids, which are widely used and occupy an important position in the power system. With the deepening development of urban power grid renovation, the capacity of 10KV distribution network has rapidly increased, and the network structure is becoming increasingly perfect. In addition, according to the needs of urban construction, overhead bare conductors are gradually being replaced by cables and insulated wires. At the same time, fire accidents caused by overvoltage in switchgear and expensive household appliances are also common. Therefore, how to effectively and economically limit the overvoltage problem in the distribution network has become a key focus of current power supply and consumption work.
The neutral point of a 10KV distribution network can generally be divided into ungrounded system, resistance grounded system, and arc suppression coil grounded system. Due to the fact that choosing a grounding method is a comprehensive issue involving factors such as the insulation level of the line and equipment, communication interference, relay protection composition, and the safety and reliability of the power supply network, the power supply systems of China's distribution network and large industrial and mining enterprises have different practices. Previously, most of them used the operation mode of neutral point ungrounded or grounded through arc suppression coils. In recent years, some urban power grids have vigorously promoted the operation mode of resistance grounding.
In the mid-1980s, the 10kV distribution network in cities such as Guangzhou developed rapidly. A large number of cables were laid in the central area of the city, and the single-phase grounding capacitor current increased rapidly, reaching over 60A in 1987. Although arc suppression coils were installed, due to the large capacitance current and frequent changes in operation mode, it was difficult to adjust the arc suppression coils. In addition, some cables with low insulation levels were used. In order to reduce the overvoltage level and minimize the possibility of phase to phase faults, the neutral point was grounded through low resistance.
According to the research results of the Quzhuang substation in Guangzhou, using a neutral point grounded with low resistance, when Rn �� 10 ��, in most cases, the single-phase grounded power frequency voltage can be raised and reduced to around 1.4 p.u. Considering the limitation of arc grounding overvoltage, during the process of arc ignition to extinction, the excess charge accumulated by the system can be leaked out through Rn within the second half of the power frequency cycle after extinction, and the amplitude of overvoltage can be significantly reduced. According to this requirement, the low resistance value of the neutral point should meet the following conditions:
Rn��1/3��C0
When Rn=10 ��, the arc grounding overvoltage can be reduced to below 1.9p.u.
If the selection of neutral point resistance value is too low, the single-phase grounding current will be large, which will cause significant interference to communication lines; If the resistance value is too high, the relay protection action will be unreliable. Generally speaking, there is no problem with interference to communication lines when the current in the neutral point resistance is between 100-200A. Under these conditions, the neutral point resistance value of a 10kV overhead line is 28.80-57.74 ��. For cable based distribution networks, according to Japan's experience, the interference problem with communication lines is not significant when the current in the neutral point resistance is between 400-800A. Therefore, the range of neutral point resistance values for 10kV cable distribution networks should be 7.2-14.4 ��.
From the perspective of ensuring the reliability of relay protection actions, it should have high sensitivity when a single-phase grounding fault occurs. There are two types of grounding relays: one is the grounding overcurrent relay, and the other is the grounding direction relay that operates based on the direction of zero sequence current.
The sensitivity of protection is not a problem when using overcurrent relays in the event of metallic grounding. However, when grounded through a transition resistor, a significant portion of the overhead lines have single-phase grounding faults, resulting in high resistance at the fault point and some issues with the sensitivity of protection. For cable lines, the transition resistance during single-phase grounding is generally small, which has little impact on the sensitivity of relay protection.
Finally, starting from the requirement of limiting resonance overvoltage, when the cable line is particularly long, there may be a situation where j �� Le=1/j �� C, which can cause resonance. If the neutral point has appropriate resistance, the abnormal voltage on the healthy phase can be limited.
The method of grounding the neutral point through low resistance, especially when single-phase grounding is mainly used in distribution networks with overhead lines, will greatly increase the number of trips. If the ring network power supply cannot be achieved or the line is not equipped with reclosing, the number of power outages will increase, reducing the reliability of power supply. However, for cable based distribution, the fault rate is extremely low, and this problem is not prominent.
Based on the specific situation in China, it is recommended that distribution networks with cable based capacitor currents exceeding 150A can adopt low resistance grounding methods, with corresponding fault current levels of 400-1000A. For 10kV systems, the neutral grounding resistance value can be taken as RN=10-20 ��.

[Low voltage resistor]LXQ series harmonic elimination resistor

2026-6-19 13:06:11

1�� Overall Introduction
The LXQ type 6-35 kV voltage transformer neutral point damping device (referred to as L-type damping device) is a nonlinear damping device installed between the neutral point of the primary winding YO of the 6-35 kV voltage transformer (referred to as voltage transformer or P.T) and the ground. LXQ type refers to the use of damping devices for pressure neutral points protected by exposed intangible ceramic sleeves.
The DC characteristics of LXQ type harmonic eliminator are similar to those of traditional RXQ type harmonic eliminator, but the structural design is quite different. It uses high-density SiC as the base material and is composed of multiple nonlinear harmonic damping elements that are fired at over a thousand degrees Celsius and connected in series. Small size, light weight, high strength, fast heat dissipation, easy to install, no need for external ceramic sleeve protection. The exposed surface structure has undergone special treatment and can withstand exposure to sunlight, rain, and extreme cold and heat. It can be directly used outdoors and is very popular among users.

2�� Electrical application functions
1. Used to eliminate or dampen electromagnetic resonance overvoltage caused by voltage saturation, which can lead to unstable phase voltage in the system.
2. Used to limit the inrush current generated in the primary winding circuit of the transformer when the single-phase grounding of the system disappears, which can damage the transformer or cause the fuse of the transformer to melt.
3. Used to prevent voltage damage for a long time after a single-phase grounding occurs in the system.

Taking the smallest space handcart cabinet as an example; The X end of the JDJJ2-35 transformer primary coil in the JYN1-35 transformer cabinet is located on the fuse side, and a hole (�� 12) can be drilled on the side of the fuse bracket to fix the LXQ-35 (B) type harmonic eliminator on the side of the bracket. The harmonic eliminator is installed horizontally.
6�� Friendly reminder
If the neutral point of the power grid where the 6-35kV substation is located is not grounded, the electromagnetic transformer primary winding connected by YO on its busbar becomes the only metal channel for the neutral ungrounded power grid to ground. Therefore, the charging and discharging path of the power grid relative to the ground capacitor must pass through the transformer primary winding. This slow process saturates the transformer core deeply. Therefore, when the power grid grounding disappears, a surge of several amperes will appear in the transformer primary winding, melting the transformer 0.5A fuse. If you choose LXQ type resistors, this phenomenon will no longer occur. The LXQ resistor can effectively suppress the inrush current of the primary winding of the transformer, while the electronic harmonic eliminator installed on the secondary side of the transformer cannot limit this inrush current. If a surge occurs, short circuiting the secondary opening triangle will only increase the amplitude of the surge. Therefore, for the voltage transformer that has already installed LXQ type resistors, it is recommended to disable the electronic harmonic eliminator that uses short-circuit method to eliminate harmonics in the three port triangle.
If the neutral point of a 6-35KV substation is not grounded, and the relative ground voltage is unstable when the bus is unloaded or there are few outgoing lines, you can choose LXQ type resistors, which will greatly reduce this phenomenon. The resistance value of LXQ type resistors can effectively suppress ferromagnetic resonance caused by voltage changes. Since the resistor is installed between the neutral point of the voltage transformer and the ground, that is, in the zero sequence circuit of the voltage transformer, it does not affect the voltage measurement and energy measurement connected between the secondary lines of the voltage transformer. It only has a slight impact on the measurement of the relative ground voltage value in the zero sequence circuit of the voltage transformer. This voltage value is used as an observation of the relative ground insulation, and this slight impact is generally acceptable

[rheostat]BP6 series frequency sensitive variable resistor

2026-6-19 11:43:15

The BP6 series frequency sensitive variable resistor is suitable for three-phase AC wound asynchronous motors with a frequency of 30Hz. Used for starting heavy loads. The frequency sensitive variable resistor is designed as a four tube structure, consisting of two parts: the iron core and the winding. The iron core has two rings per phase, with aluminum rings on the outermost and second layers, iron rings on the~th and innermost layers, and thick steel plates on the surface. The four tube structure is based on the BP4 series and is equipped with inner aluminum rings and inner iron rings. At the beginning of the motor start-up, due to the skin effect of the current, the magnetic flux is concentrated on the outer iron ring. As the motor speed increases, the slip rate gradually decreases, the skin effect weakens, and the magnetic flux gradually enters the inner iron ring, increasing the induced electromotive force in the inner aluminum ring. Its effect is equivalent to paralleling a resistor with gradually decreasing resistance on the outer aluminum ring. When the parameters are appropriate, the equivalent resistance of the inner and outer aluminum rings is proportional to the square root of the slip rate, and the variable resistance ability can be greatly improved. Therefore, the mechanical characteristics of this four tube frequency sensitive variable resistor are superior to the BP1, BP2, BP4 and other series.

2�� Model and meaning:

3�� Technical performance and data:
When the minimum grid voltage during the starting process is not lower than 90% of the rated voltage, the variable resistance can reliably start the motor with rated load for three consecutive times (with a total starting time not exceeding 90 seconds) after adjusting the tap appropriately. The stator impulse current of the motor during starting should not exceed 2.5 times the rated current.

Basic parameters of BP6 series frequency sensitive rheostat:

Pe - rated power of electric motor in kilowatts; E20-- Open circuit voltage of motor rotor in voltsThe rated current of the motor rotor is A.

4�� Usage and adjustment:
When the variable resistor leaves the factory, the wiring is connected to the 85% tap of the coil. If the motor is connected to the variable starter and any of the following situations occur, adjustments can be made according to the following method:
1. The starting current is too high (greater than 2.5 times) and the starting speed is too fast. You can try to increase the number of turns and connect the tap to 100% of the turns. The effect is to reduce the starting current and the starting torque at the same time.
2. When the starting current is too small (less than 2 times) and the starting torque is not enough, and the starting is too slow, try to reduce the number of turns and switch the tap to 71% of the turns. The effect is to increase the starting current and the starting torque at the same time.
3. If the ball mill and other machinery have difficulty restarting after a period of shutdown due to heavy mechanical loads (steel damage and powder agglomeration), the motor can be turned several times to flip the ball mill cylinder a few times before it can start normally

[rheostat]BP1 series frequency sensitive variable resistor

2026-6-19 11:42:50

The BP1 series frequency sensitive variable resistor (hereinafter referred to as the variable resistor) is suitable for use with three-phase AC wound asynchronous motors with a capacity of 22kW, 50Hz as light loads or occasionally used for heavy and light loads (such as water pumps, air compressors, steel mills, air compressors, etc.), or for repeated short-term work cycles (such as bridge cranes, lifting platforms, mining conveyors, etc. with a capacity of 2.2kW to 125kW).

Environmental conditions for use
Varistors can reliably operate under the following conditions:
1. Altitude not exceeding 4000m;
2. The temperature of the surrounding medium shall not be higher than+40 �� and not lower than -30 ��;
3. The relative humidity of the air shall not exceed 85% [(20 ± 5) ��];
4. In a medium without explosive hazards, and without gases or dust that can corrode metals and damage insulation in the medium
5. Places that are protected from rain and snow, but not filled with water vapor;
6. Places that allow for general vibrations and impacts;
7. At any angle from the vertical plane.
structural characteristics
A rheostat is a non-contact electromagnetic component that is equivalent to an equivalent impedance. During the starting process of the electric motor, the equivalent impedance automatically decreases with the decrease of high-frequency components in the rotor starting current to achieve automatic resistance change. Therefore, only a first stage variable resistor is needed to start the electric motor smoothly.
A variable resistor is essentially a three-phase reactor with a very high iron core loss. It consists of two main parts: an iron core and a coil, which are made up of several E-shaped steel plates stacked together. Steel plates are clamped with washers to maintain the distance between them for heat dissipation. The structure and installation dimensions are shown in Figure 1 and Table 1.

Scope of application

The BP3 series frequency sensitive variable resistor (hereinafter referred to as BP3) is suitable for starting 2.2-125kW, JZR series wound asynchronous induction motors under frequent operation. BP3 is often connected to the motor rotor circuit and generally does not require additional short-circuit devices. The model meaning of BP3 is the same as that of BP1 series.
Usage
BP3 can be divided into three categories based on the frequency of operations:
1. Type 1: Slightly frequent, 100-400 times per hour. Such as the motor on the translation mechanism of the bridge crane in the mechanical workshop, the furnace roller, the steel pulling machine, etc. Most of them cut off power as soon as they start.
Series Table
According to the different specifications of the motor and the frequency of operation, the specifications and number of each group of frequent variable resistors can be directly found in the following table. The series tables are shown in Table 1 and Table 2
The BP3 series table applicable to JZR series motors is shown in Table 1
2. The second type: more frequent, 400-600 times per hour. Such as the motor on the translation mechanism of the bridge crane in the Jin steel rolling workshop, the front and rear working rollers of the rolling mill, and the extension roller. Most of them cut off power as soon as they start.
3. The third category: frequent operations, 600-1000 times per hour. Such as lifting platform, lifting platform roller conveyor, pressing device, steel pulling machine, rolling mill intermediate roll, etc.
