Description

Technical Field

[0001] The present invention relates to the technical field related to a trip device, and in particular to an emergency trip device operated remotely. Background Art

[0002] The circuit breaker is usually opened by remote control, so that the circuit breaker opening coil is energized, and then the circuit breaker is tripped to complete the opening. In the long-term operation process, due to the looseness of the secondary circuit contacts, damage to the relay, abnormal protection and control device, and the detachment of the auxiliary switch connecting rod, the circuit breaker may not be opened remotely, and it needs to be handled immediately. If it is not handled in time, when a short circuit fault occurs in the line, the fault line switch will refuse to operate, causing the protection to trip, causing unsafe factors such as large-scale power outages. When the control circuit of the operating switch cabinet and ring network cabinet is disconnected, there are currently two main ways to deal with it. One is to isolate the faulty equipment after the upper equipment is powered off, and the other is for the operator to go to the faulty equipment and mechanically open it (and the switch of the ring network cabinet needs to be manually operated on the spot whether it is opened or closed). The first treatment method will expand the scope of the power outage. The second treatment method has the risk of explosion when the running circuit breaker cuts off the load current, which directly endangers the life safety of the operator.
