ZW32-6 ~ 15 kV Outdoor high voltage vacuum circuit breaker

Product Overview
The ZW32-6–15 outdoor high-voltage vacuum circuit breaker is an outdoor power distribution device designed for a rated voltage of 6–15 kV
and a three-phase AC frequency of 50 Hz. This circuit breaker is primarily used for breaking and making load currents, overload currents and
short-circuit currents in power systems, as well as for instantaneous protection, earth fault protection, selectable number of reclosing operations,
local remote control and remote communication functions. It is suitable for use in substations and the power distribution systems of industrial and
mining enterprises for protection and control purposes. In the event of a fault occurring within a user’s premises on a 6–15 kV line with a T-type
connection, or where the fault occurs on the user’s side of the incoming switch but the protection time delay does not match that of the
substation’s outgoing switch, this will cause the substation’s outgoing switch protection to trip. If the fault is permanent and the substation is
unable to successfully reclose, a fault within a single medium-voltage user’s premises will result in a power outage along the entire distribution
feeder. Such cascading faults, which are common in power grids, can cause significant losses to society. The ZW32-6 ~ 15F outdoor high-voltage
vacuum circuit breaker (hereinafter referred to as the circuit breaker) is installed at the boundary of responsibility on the overhead line, i.e. at the
front end of the user feed-in. It will automatically isolate single-phase earth faults and phase-to-phase short-circuit faults within the user’s
premises, preventing faults within the user’s boundary from affecting the transmission trunk line, ensuring the safety of electricity supply to non
faulty users, and improving the reliability of electricity supply.
