Audited Supplier When the T-connected branch line of the 12kV overhead distribution line or the internal fault of the end user occurs, the outgoing switch of the substation will be tripped when the protection action time limit of the incoming line switch and the protection time limit of the outgoing line switch of the substation cannot be reasonably adjusted. If the nature of the fault is permanent, the substation reclosing will not be successful, and a local accident within the medium voltage user boundary will cause the entire 12kV distribution line to lose power. If an outdoor demarcation circuit breaker is installed at the T junction or at the user end (responsibility demarcation point), it is determined that a fault (overcurrent, short circuit, single-phase grounding, etc.) occurs in the user boundary, and the fault is automatically isolated. Users in non-faulty areas use electricity normally. The application of ZW32-12F outdoor high-voltage intelligent demarcation vacuum circuit breaker (watchdog) on 12kV feeder overhead line can avoid the joint accidental power failure of the fault-free line, reduce the scope of fault power outage, shorten the user's power outage time, and protect the safety of the main network run. And it has the function of fault detection, protection control and communication, which can realize automatic removal of single-phase ground fault and automatic isolation of phase-to-phase short-circuit fault. The installation point is used at the responsibility demarcation point between the user's incoming line of 12kV distribution line, and it can also be applied to the branch line connection that meets the requirements.
