Equipment may all be caused to be in charged state, capacitance voltage constantly rises, and ultimately causes the explosion of device overvoltage.To protect other
Partly, it prevents from exploding, reduces the influence to entire valve group and system, need in time failure removal.Mechanical bypass switch moves
The regular hour is needed, charging current may cause voltage further to increase within this time, it is therefore desirable to equipment in addition
Quickly cut off failure.
The alternating current-direct current power network overvoltage that time is extremely short, amplitude is high, generally can not be only such as switching overvoltage, lightning surge
It is protected by protection system, needs to design by rational pressure resistance, such as configuration spark gap is prevented.But spark gap
Actuation time it is relatively short, therefore, it is necessary to be directed to the advantage and disadvantage of protection system and spark gap, formulating a kind of more quickly has
The protection system of effect can prevent overvoltage stress after supervention in system disturbance, module failure or alternating current-direct current power network overvoltage
Exhibition improves the reliability of transverter.
