[Low voltage resistor]SNGR series neutral grounding resistor

2026-6-19 13:06:52

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.

3�� Main functional parameters of LXQ series harmonic elimination resistor:

model	DC characteristics	nonlinear coefficient	Heat capacity 250mA (10min)	Dimensions: Length * Width * Height (mm)	Weight (kg)
LXQ-6-10 (connected between the neutral point of the primary coil of the 6-10KV voltage transformer and the ground)	1.45-1.65/15	0.40-0.45	through	5050260	one point six
LXQ-35 type (connected between the neutral point of the 35KV voltage transformer primary coil and the ground, with a neutral point insulation strength greater than 5KV)	4.0-4.2/42	0.4-0.45	through	5050375	two point four
LXQ-35 type (connected between the neutral point of the 35KV voltage transformer primary coil and the ground, with a neutral point insulation strength of less than 5KV)	>=2.8/50	0.3-0.4	through	5050260	one point six

4�� Usage environment
1. Environmental temperature: -40 ��~+40 ��;
2. Frequency: 50HZ or 60HZ;
3. Areas with seismic intensity below 8 degrees.
5�� Installation instructions
The LXQ type harmonic eliminator has a small body but high mechanical strength, and can be installed vertically or horizontally; It can be directly fixed on the bolts of the transformer body or on the bracket near the transformer. 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
