KYN28‑12 Indoor AC Metal‑clad Withdrawable Switchgear is a complete indoor medium‑voltage distribution device for three‑phase AC 50Hz, rated voltage 12kV. It is applicable for single‑bus and single‑bus sectionalized distribution systems. It is mainly used for power receiving and energy distribution in power plants, substations, industrial‑mining enterprises and new‑energy power stations. It can also drive high‑voltage motors and realize control, protection, measurement and monitoring for primary circuits.
The cabinet is assembled from aluminum‑zinc coated steel plates through CNC processing and multi‑folding technology, featuring high mechanical strength and corrosion resistance. The cabinet is divided into four mutually‑isolated independent compartments. The circuit breaker adopts middle‑mount withdrawable structure. The handcart is equipped with working, test and isolation positions with reliable positioning and electrical interlocks. The unit is fitted with complete five‑prevent interlock functions. Each high‑voltage compartment is equipped with pressure‑release devices to restrain the spread of internal‑fault arcs.
