Composite station Lightning Arrester is a new type of arrester developed in the 1970s. It is mainly composed of zinc oxide varistor. [2] Every varistor has a certain switching voltage (called varistor voltage) from the time of manufacture. Under normal working voltage (that is, less than the varistor voltage), the varistor value is very large, which is equivalent to an insulation state , But under the action of the impulse voltage (greater than the varistor voltage), the varistor is broken down at a low value, which is equivalent to a short-circuit state. However, after the varistor is hit, the insulation state can be restored; when the voltage higher than the varistor voltage is removed, it returns to the high resistance state. Therefore, if a zinc oxide arrester is installed on the power line, when a lightning strike occurs, the high voltage of the lightning wave will cause the varistor to break down, and the lightning current will flow into the ground through the varistor, and the voltage on the power line can be controlled within a safe range. Thereby protecting the safety of electrical equipment.
Function
This product is designed with 27 shed and is suitable for 30-37KV, 10KA power station lines. At the same time, it can also be used on 5KA power station lines after the change of resistors. The shed diameter is 110/80mm. The creepage distance is: 1200mm, in the case of 10KA (8/20), the residual voltage is: 94KV, and the effective value of the continuous operating voltage is 28.8KV. The entire product is produced in strict accordance with IEC 6009-4&GB/T11032-2010.
