Protect test macro.
Background technique
Series capacitor compensation technology is that capacitor is connected in series in route, high pressure is worked as in order to improve route conveying capacity
In the event of failure, the metal oxide arrester in parallel with capacitor (MOV) will act route immediately, while limiting capacitance device two
Hold voltage change, but when the energy of MOV accumulation cannot scatter and disappear quickly, will explode and then be damaged, thus the both ends MOV simultaneously
Join a spark gap, when a fault is found, the movement of pilot spark gap is finally quick by control system control bypass breaker
Bypass, protective condenser and MOV.It can be seen that the trigger device of spark gap is very important, if cannot be fast and reliable

The part such as (Metal Oxide Varistor, metal oxide pressure-limiting device), discharging gap, series compensation platform is constituted.Series capacitance
There is dedicated string to mend protective device, mended with realizing to string as independently of the primary equipment except transmission line of electricity for compensation device
The real time monitoring and protection of the parts such as capacitor, MOV, discharging gap, series compensation platform.String mends protective device and is different from other once
Equipment protecting equipment has the following characteristics that 1) string mends protective device and the difference of other primary equipment protective device principles is larger.2)
Analog acquisition circuit is more, and defencive function is more.3) it is high to mend protective device the result of the action similitude for string.
