Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is further elaborated.
Embodiment 1:
As it is shown in figure 1, the direct current handover security interlocking gear of a kind of electrophoresis commutator, including the direct-current isolating switch KIRkey safety lock 6 for controlling direct-current isolating switch 2 operation, for controlling electrophoresis door KIRkey safety lock and the device for exchanging keys 1 of electrophoresis door operation；Described direct-current isolating switch KIRkey safety lock is identical with the number of described direct-current isolating switch 2 and electrophoresis door respectively with the number of electrophoresis door KIRkey safety lock；Described device for exchanging keys is arranged on switching cabinet panel；When the key of all corresponding electrophoresis door KIRkey safety locks is inserted simultaneously into device for exchanging keys 1, the key of described direct-current isolating switch KIRkey safety lock just can be removed；When described direct-current isolating switch KIRkey safety lock is in connected state, the key of corresponding electrophoresis door KIRkey safety lock all can not take out from described KIRkey safety lock device for exchanging keys.
The direct current handover security interlocking gear of described electrophoresis commutator, also includes and the operation interlock of the same number of direct-current isolating switch of described direct-current isolating switch Yu electrophoresis commutator；The operation interlock of described direct-current isolating switch and electrophoresis commutator is used for locking direct-current isolating switch state.
The operation interlock of described direct-current isolating switch and electrophoresis commutator includes operation dead bolt 3, isolator operation rotating disk 4, main circuit breaker electromagnetic tripping apparatus control switch 5；Described operation dead bolt 3 is suitable with described isolator operation rotation dish 4；When described operation dead bolt 3 inserts described isolator operation rotation dish 4, described direct-current isolating switch 2 is lock-out state, and it is OFF that described main circuit breaker electromagnetic tripping apparatus controls switch 5, it is allowed to main circuit breaker closes；When described operation dead bolt 3 exits described isolator operation rotation dish 4, described direct-current isolating switch 2 is non-locking state, described operation dead bolt 3 cannot drive main circuit breaker electromagnetic tripping apparatus to control switch 5 and automatically become ON state, make main circuit breaker electromagnetic tripping apparatus action, the automatic breaking of main circuit breaker.
