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).

Purpose:

The FS series valve type lightning arrester is used to protect electrical equipment such as distribution transformers and cable heads from damage caused by atmospheric overvoltage.
It is suitable for:
1. Indoor and outdoor: The usage location has an ambient temperature of -40 �� to+40 ��.
2. The use of high-altitude lightning arresters shall not exceed 1000m, and high-altitude lightning arresters shall be used in areas above 1000m.
3. The maximum power frequency voltage relative to ground 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 FS series lightning arrester consists of spark gaps and valve plates stacked in a single column within a ceramic sleeve, with rubber seals at both ends of the sleeve. Iron clamps and wiring bolts are provided for installation and wiring.
The FS8 series lightning arrester is a modified product of the FS4 series lightning arrester. Its internal structure and electrical characteristics are the same as those of the FS4 series, but it has the following characteristics:
(1) The product is filled with high-purity dry nitrogen gas inside to prevent ozone generation from corona discharge, thereby ensuring stable product performance.
(2) The upper metal cover has been replaced with a porcelain cover structure, which solves the problem of rust on the upper iron cover.
(3) Using special bolts to sprout wiring from the upper end of the porcelain sleeve, replacing the wiring terminals on the metal of the welder, to avoid the disconnection of the wiring terminals.
(4) The upper end of the porcelain sleeve is sealed with double-layer rubber to ensure reliable sealing performance.
The ceramic sleeve and iron cover of the high-altitude lightning arrester are welded and sealed with metal and ceramic parts, which has excellent sealing performance and can be applied to any altitude area.

Technical standards:
The performance of the FS series valve type lightning arrester meets the requirements of the national standard "GB7327-87 Silicon Carbide Valve Type Lightning Arrester for AC Systems", and its main performance is shown in the characteristic table.
