When a fault occurs in the user's T-connection of the 10kV overhead distribution line, such as the fault is in its incoming line, or although the fault occurs inside the user's incoming switch but its protection action time limit is not matched with the substation outgoing switch protection, it will cause the substation to go out. The switch protection has tripped. If the nature of the fault is permanent and the substation recloses unsuccessfully, an accident in the medium-voltage user sector will cause the entire distribution line to be out of power. This common spreading accident in the distribution network will have a bad impact on the society.
The ZW32-10KVoutdoor high-voltage AC boundary vacuum circuit breaker is an ideal device to solve the above-mentioned accidents. A zero-sequence current transformer is built in the outlet side of the device, which is used in conjunction with the boundary controller. Installed at the T-connection or user end of 10kV overhead distribution lines, it can automatically remove single-phase ground faults and automatically isolate phase-to-phase short-circuit faults. Ensure the safety of electricity for non-faulty users. It is suitable for use in substations, industrial and mining enterprises, and rural power distribution systems for protection and control and frequent operations.
