Description
The three-phase combination overvoltage protector product, due to its phase to phase and phase to ground protection functions, successfully solves the problem of operating overvoltage caused by the disconnection of the vacuum switch and the harm to equipment insulation. However, with the increasing expansion of the system and the common use of cables and nonlinear loads, operating overvoltage and harmonic overvoltage are becoming increasingly severe, leading to more frequent action of the protector, accelerated aging of the valve plate, and correspondingly shortened the expected life of the protector. As a result, under abnormal conditions such as system resonance overvoltage, the protector itself collapses, leading to inter phase short circuits in the switchgear and causing significant economic losses to users. This product has characteristics such as large flow capacity and four star line connection method.

Parameters:

Protection object:
A-electric motor
B-Generators, Transformers, Bus Lines, Switches
C-parallel compensation capacitor
O-motor neutral point

Continuous operating voltage: allows for sustained application of effective values of power frequency voltage between phases and phase to ground in BWKG, 3.8 for 3KV system, 7.6 for 6KV system, 12.7 for 10KV system, and 42 for 35KV system

Application occasions: Widely used in various industries such as wind power, electricity, petroleum, chemical industry, metallurgy, cement, steel, copper industry, ports, etc.
