A GIS switch cabinet is disclosed. A high voltage component is arranged in the cabinet. The high-voltage component includes a three-station switch, a voltage transformer grounding switch, a single-phase voltage transformer, a circuit breaker, a circuit breaker switch, a three-station switch control mechanism and a bus. The three-station switch, the voltage transformer grounding switch, and the circuit breaker are arranged in a closed gas box filled with sulfur hexafluoride. The single-phase voltage transformer is connected below the voltage transformer grounding switch, and the circuit breakerswitch is connected to the circuit breaker in the gas box through a sealing ring. The three-station switch control mechanism is connected to the three-station switch, and the bus passes through an upper portion of the gas box and is connected to the three-station switch 1. The high-voltage component is installed in the gas box, and the gas box is supported by a gas box support pedestal. In the GIS switch cabinet of the invention, power distribution devices are completely insulated and sealed by a sulfur hexafluoride gas, which has very high safety and reliability. Compatibility of differentschemes from 12kv-1250A to 40.5kv-2500A can be achieved and movement is easy.
