Description
Technical field
The present invention relates to a kind of portable protection pressing plate voltage check device, detect during grid switching operation and wait to put into
Pressing plate both end voltage and pressing plate two ends voltage-to-ground.
Background technology
Protection pressing plate is also named protection in flakes, is bridge and the tie of protection device contact external wiring, accesses according to pressing plate
The difference of protection device secondary circuit position, can be divided into defencive function pressing plate and the big class of output clamping two.Defencive function pressing plate is real
Show some function (such as the throwing, retreating of main protection, distance protection, zero-sequenceprotection etc.) of protection device.This pressing plate is generally light current
Pressing plate, meets direct current 24V.Also have forceful electric power function pressing plate, meet direct current 220V or 110V, but before entering device must through photoelectric coupling or
Disconnecting relay isolate, be converted into light current open into, its capacity of resisting disturbance is more preferable.Output clamping determines the result of protection act,
Object according to protection act outlet effect is different, can be divided into tripping operation output clamping and start pressing plate.Tripping operation output clamping is direct
Act on this switch or connection jumps other switches, generally forceful electric power pressing plate.Start pressing plate and open into being used, as malfunctioning as other protections
Start pressing plate, locking prepared auto restart pressing plate etc., different according to accessing loop, there is forceful electric power also to have light current.
