2026-6-20 14:24:23

The TLB-1 lightning arrester uses a hot melt explosive release device as a special matching product for the lightning arrester, which is used in series with the lightning arrester. When the lightning arrester fails, it can quickly act to remove the faulty lightning arrester from the power grid, and provide a clear disconnection sign for maintenance personnel to discover the fault point and replace the lightning arrester. On the other hand, when the lightning arrester is working normally, the disconnector does not move and exhibits low impedance, which does not affect the protection characteristics of the lightning arrester. The installation of a disconnector lightning arrester is the only way to truly achieve safe and maintenance free use, convenience and reliability. Separators are commonly used in distribution, power station, and line lightning arresters operating in developed countries and regions such as Europe, America, and Japan.

The disconnector adopts a new thermal explosion design, which has the advantages of fast response and error free operation, and can be used in conjunction with various types of lightning arresters above 3kV. The usage conditions are the same as those of lightning arresters.
The typical ampere second characteristic parameters of TLB-1 thermal explosive disconnector are as follows:

[Valve type lightning arrester]FZ series valve type lightning arrester

2026-6-20 14:20:06

Application of FZ series valve type lightning arrester:

The FZ series 3-110kV valve type lightning arrester is a protective electrical device used to protect the insulation of AC substation equipment from atmospheric overvoltage damage.
This applies to:
1. Indoor and outdoor: The ambient temperature of the usage location is -40 �� to+40 ��;
2. The altitude of the usage location shall not exceed 1000m;
3. The maximum relative frequency voltage that may occur at the installation site should not exceed the rated voltage of the lightning arrester.
It is not suitable for places with severe pollution and violent vibrations.
Structure and performance:
The FZ series lightning arrester consists of three parts: top cover, basic components, and insulation base. In addition to the above three parts, the 110kV lightning arrester is also equipped with a voltage equalization ring. The basic components are sealed and equipped with spark gaps, valve plates, and pressure equalization resistors. A 35~110kV lightning arrester is composed of three standard basic components with voltages of 15, 20, and 30kV, as well as two other non-standard basic components with voltages of 15 and 30kV. The FZ series lightning arrester has two types of bases, and products with different voltage levels require bases of different heights.
1. The lightning arrester is connected between the high-voltage wire and the ground. When atmospheric overvoltage occurs on the wire that poses a threat to the substation equipment, the spark gap will activate. Due to the action of the spark gap and valve plate, the amplitude of the overvoltage on the protected equipment is limited, the insulation of the equipment is protected, and the power frequency continuous current is cut off within 0.01 seconds, restoring the system to its political working state.
(1) Conductance current measurement: Apply a direct current voltage (with a fluctuation of no more than ± 1.5%) specified in the characteristic table to both ends of the basic component, and the conductivity current flowing through the basic component should comply with the specifications in the characteristic table.
(2) Insulation resistance test: Use a 2.5kV megohmmeter to measure the insulation resistance of basic components, and the resistance value is not specified. But the results of each experiment should be similar.
2. During transportation and storage, it should be placed upright.
3. During operation, the original paint layer of the lightning arrester should be repainted every 1-2 years.
4. During installation, the horizontal tension of the top lead of lightning arresters with a voltage range of 3-60kV should not exceed 294N (30kgf), and for 110kV lightning arresters, it should not exceed 196N (20kgf).
5. FZ-110 lightning arrester is used to protect 110kV AC transformer equipment with neutral point not grounded or grounded through arc suppression coil from damage caused by atmospheric overvoltage. A basic section of 15kV non-standard components (with different characteristics from 15kV standard components) is installed at the top, while the remaining four sections are composed of 30kV non-standard components (with different characteristics from 30kV standard components).

Three phase combined composite jacket metal oxide surge arrester for 3-35kV AC system

Overview
The three-phase combined composite jacket metal oxide lightning arrester used in 3-35kV AC systems is suitable for the overvoltage between phases and between phases and ground caused by frequent operation in 3-35kV power systems, to protect transmission and transformation equipment from damage caused by operating voltage.
There are two types of products: those without gaps and those with series gaps.
The development of three-phase combined overvoltage protectors has changed with the development of single lightning arrester technology. Introduced to China by Sweden in 1976. At that time, silicon carbide valve plates were used in series with gaps in lightning arresters, and combined lightning arresters were also made of silicon carbide valve plates in series with gaps. This type of lightning arrester has the following drawbacks:
1. High discharge dispersion;
2. Poor volt ampere characteristics and high impact coefficient;
3. There is an issue of arc extinguishing.
In 1983, China introduced advanced manufacturing technology for zinc oxide lightning arresters from abroad, and the manufacturing level of zinc oxide valve plates has reached the international advanced level. The zinc oxide valve plate has excellent non neutral line performance, aging resistance, and thermal stability. The gapless zinc oxide arrester has replaced the series gap silicon carbide arrester, and the corresponding gapless combined arrester has also developed into the gapless combined zinc oxide arrester. The gapless three-phase combined zinc oxide arrester is the best product for phase to phase and phase to ground overvoltage protection. It is recommended that users choose a three-phase combined ground gap zinc oxide lightning arrester.
Product Features
protection method
Due to the use of four element star connections, it can simultaneously protect against phase to phase and phase to ground overvoltage, and one can function as three phase to phase and three phase to ground lightning arresters.
Excellent protection performance
Due to the use of metal oxide resistors with excellent nonlinear volt ampere characteristics, the protection margins for steep wave impulse residual voltage, lightning impulse residual voltage, and operational impulse residual voltage are nearly consistent, making the insulation coordination of the system more reasonable.
Specification and main technical parameters of lightning arrester
The performance of the three-phase composite jacket gapless metal oxide lightning arrester fully meets the requirements of GB11032-2000 "AC gapless metal oxide lightning arrester" standard. The specifications and main technical parameters of the lightning arrester are shown in Table 6.
The performance of the three-phase composite jacket with series gap oxide lightning arrester meets the standards of GB11032-2000 and ZBK49005-90.
The specifications and main technical parameters of the lightning arrester are shown in Table 7.

[Zinc oxide lightning arrester]HY5WS-17/50DL Drop out fuse lightning arrester combination

2026-6-20 13:59:54

The HY5WS-17/50DL drop type (throwable, detachable) lightning arrester is a modified distribution type zinc oxide lightning arrester that is cleverly installed on the drop type mechanism of the drop type fuse. It can be easily inspected, repaired, and replaced with the help of an insulated switch control rod under continuous power supply, ensuring the smooth operation of the line and greatly reducing the workload and time of power maintenance personnel. It is particularly suitable for places where power outages are not advisable, such as postal and telecommunications, airport stations, hospitals, and bustling commercial areas. The other performance of the product is the same as that of the distribution type lightning arrester

Installation and usage instructions
1. Before installation and use, please check the tightness between the lightning arrester components and the drop mechanism to ensure good contact and operation
Flexible unloading.
2. The upper terminal of the drop mechanism is connected to the high-voltage line, and the lower terminal must be reliably grounded and not connected in reverse.
3. The precautions for lightning arresters before and after operation are the same as those for distribution type lightning arresters.
4. When the lightning arrester needs maintenance or replacement, it can be aligned with the lightning arrester with the help of an insulation switch control rod without continuous power supply
The pull hook on the device unit provides convenient operation, similar to replacing a drop type melting tube.

Structural features and working principle
The product is composed of four units as a whole. Each unit of the product with a series gap is mainly composed of a gap between parallel cathode rings and a non-linear excellent zinc oxide cathode plate connected in series. The product without a gap is mainly composed of non-linear excellent zinc oxide cathode plates connected in series within each unit. Assuming that the four unit leads are A, B, C, and O terminals, with the O terminal being a grounded symbol terminal, and the four terminals being connected to the motor a, O, c, and ground terminals respectively. Under normal operation, the relative ground voltage of each phase is borne by A and O units, B and O units, and C and O units, respectively. The phase to phase voltage is borne by A, B units, A, C units, and B, C units, respectively. When a large current flows, the zinc oxide valve plate is in a low resistance state, which limits the phase to ground and phase to phase residual voltage of the lightning arrester to the allowable values. This reliably protects the motor insulation from voltage damage. After the overvoltage wave, the current drops, and the negative value of the valve plate increases. The lightning arrester returns to its normal state and is ready to withstand the next overvoltage wave invasion

[Zinc oxide lightning arrester]Y5C,HY5C series with series gap series metal oxide lightning arrester

2026-6-20 13:57:22

The Y5C and HY5C series metal oxide surge arresters with series gap series are composed of zinc oxide resistors with excellent nonlinear volt ampere characteristics and gap series connected with parallel resistance rings. In normal working condition, the voltage is jointly borne by the resistance ring and the zinc oxide resistor. Due to the voltage divider effect of the resistance ring, the burden of the zinc oxide resistor under working voltage is reduced, and the aging problem of the zinc oxide resistor can be basically ignored.

Low impact coefficient and strong power frequency overvoltage tolerance.

Due to the use of a special gap structure, the impact of external factors such as rain and dirt on the product has been eliminated.
The appearance and installation dimensions are shown in Figures 1-7, where Figure 1 is a distribution type lightning arrester, Figures 2-4 are power station type lightning arresters, and each lightning arrester in Figures 1-4 has two installation methods: Type A (shown in Figure 5) and Type B (shown in Figure 6).
