AC closed switchgear

The invention provides an AC closed switchgear which comprises a plurality of compartments. The compartments perform a shielding function, thereby reducing electromagnetic interference between space and each device, and improving reliability in use of the AC closed switchgear, wherein one compartment is a main compartment. The compartment comprises a cabinet body and a cabinet door. The cabinet door of the main compartment is provided with a proximitor which comprises an MCU. The cabinet body of the main compartment is internally provided with vacuum circuit breakers and a driver which is usedfor switching off or switching on the vacuum circuit breakers. The proximitor is electrically connected with the driver and controls operation of the driver. Three vacuum circuit breakers are arranged and are respectively arranged on a three-phase circuit. The three vacuum circuit breakers are electrically connected with the driver so that the three-phase circuit can be respectively controlled, thereby realizing switchin
