The part for making mechanism makes operating mechanism state change, and drives moving contact movement, to complete electronic separating brake or the behaviour that closes a floodgate
Make.
The utility model has the advantages that quiet motive contact module of the invention includes two separate, pass through concatenated mode in actual use
Connection makes circuit form two breakpoints so that increase in limited bulk the fracture that opposite inlet-outlet line is formed in separating brake away from
From performance that guarantee is pressure-resistant；Meanwhile the present invention also has the characteristics that compact-sized small in size and reliable performance, and uses modularization
Component, it is easily manufactured low in cost.
The present invention has the ability for closing short circuit current and opening and closing induction current, is used in DC cabinet system, when route goes out
When existing short-circuit conditions, short circuit current can be linked into underground rapidly, then be cut off short circuit line by dc circuit breaker.
