Product DescriptionWhen the 12kV overhead distribution line T is connected to the branch line or the internal user fails, the timing of the line switch protectionaction and the substin outet switch protection time imit cannot be properlv adiusted, which will cause the substation outet switch to trip.the nature of the fault is permanent and the substation coincidence will not be successful, then a local failure in a medium voitage uselcommunity wilpower down the entire 2kv distribution ine. f an outdoor iunction breaker is instaled at the T iuncion or the customer enc(responsibility demarcation point),it is ensured that the failure (overcurrent, short circuit, single phase grounding, etc.)
In the user boundary is determined and the fault is automalically isolated, Users in non-fauily areas use power normally. ZW32-12Foutdoor high-voltage inteligent demarcation vacum circuit breaker (watchdog) can be used on 12kV feeder ovethead line to avoid theconnection of faut-free lines, thus power failure, narrowing the scope of power failure, shortening the power outage time of users, andprotecling the main network, safe operaion. t also has fault detecion function., protection control function and communicaion functionwhich can realize automatic cut-off single-phase ground fault and automatic isolation phase-to-phase shortfault. The nstalaion pointuses the responsiblity demarcalion point for the user incominga line of the 12kv distribution line, and can also be applied to the branchline connection that meets the requirements.
