Background technique
Breaker tripping is the problem that entire power industry faces always, and with the increasing of vacuum circuit breaker Years Of Service
Add, exposed problem is also more and more, breaker tripping not only will cause substation failure stop transport, influence normally produce,
Household electricity, but also relevant electrical equipment can be destroyed, to bring huge economic loss, and open circuit to electric power enterprise
Device " is refused to jump ", it will causes upper level circuit breaker trip, referred to as " overstepping ".This will be enlarged by forced outage range, or even have
When will lead to system sectionalizing, cause the serious accident of large-area power-cuts.Therefore, " refuse to jump " that bring harmfulness is more than " refusing to close "
Greatly.
Currently, existing safety guard is only applicable to spring operating breaker, it is not suitable for permanent-magnet breaker.And
Since spring operating breaker breaker tripping and closing coil cannot be electrified for a long time, so existing safety guard main purpose is to protect
Shield breaker tripping and closing coil is not burned out.In addition, existing safety guard can carry out breaker two after breaker tripping
Secondary operation, but still controlled using breaker original jump, closing loop, after the failure of breaker body jump, closing loop,
It does not have any effect.

Device is moved in permanent-magnet breaker emergency opening delay of the invention again, and main operational principle is as follows:
When miniature circuit breaker ZK is closed, entirely dynamic device is in ready state again.
Device is moved again to start to acquire the external trip signal in switchgear, and check, detection control unit are carried out by diode D
KT detects external trip signal, be closed in advance its first control contact KT-1, for external trip signal disappear after self
It keeps；Detection control unit KT detects permanent-magnet breaker action state simultaneously, when permanent-magnet breaker regular event, permanent-magnet breaker
Spare auxiliary contact QF switch to disconnect by being closed, cut off detection control unit KT monitoring circuit, detection control unit KT solution
Except the first control contact KT-1 closure, releases are not involved in the normal trip operation of permanent-magnet breaker.
When abnormal, permanent-magnet breaker unfinished tripping within the regulation trip operation time occurs in permanent-magnet breaker trip operation
Movement, detection control unit KT then control its second control contact KT-2 closure, the loop A 1-A2 of drive control contactor KM1
Conducting, the first contact 1L1-2T1 closure, the second contact 4T2-3L2 closure, third contact 13NO-14NO of control contactor KM1
It is closed, the 4th contact 5T3-6L3 disconnection, is completed at the same time the control of permanent-magnet breaker separating brake, dynamic alarm indicates, dynamic alarm is defeated again again
Out, it is latched combined floodgate return circuit.
The third contact 13NO-14NO of control contactor KM1 is closed, the coil 5-6 movement of driving alarm relay KJ1,
The first contact 1-2 of alarm relay KJ1 is closed, and completes alarm circuit self-locking function；Alarm indicator RD1 is lighted by extinguishing,
The second contact 3-4 of alarm relay KJ1 is closed, and is simultaneously emitted by caution signal, prompts permanent-magnet breaker operation irregularity.
It is completed when permanent-magnet breaker moves trip operation again, device self-resetting, while unlocking closing circuit, control connect
The 4th contact 5T3-6L3 (closing locking contact) of tentaculum KM1 restores to closed state, but does not release alarm instruction and alert defeated
Out, because device action indicates that exception occurs in permanent-magnet breaker trip operation, needs manually to press non-locking press-button RD2,
Disconnect its contact NC-C, finishing device alarm resets.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
