The invention discloses a switch cabinet with an isolation switch. The switch cabinet comprises a power cut-off device and a trigger switch part. The power cut-off device comprises two cable connecting parts and a rotary disc sandwiched between the cable connecting parts. The cable connecting parts comprise installation seats and disc bodies. Each disc body is provided with multiple annular grooves. Multiple wire penetrating holes are formed in the grooves. Each penetrating hole is internally provided with a branch wire conductive bar. The disc bodies are connected with integrated wires. Two locating holes are vertically formed in the rotary disc in an axially-symmetric mode. Two locating steel balls are arranged in the locating holes. A locating spring is arranged between the locating steel balls. Pits correspondingly matched with the locating steel balls are formed in the disc bodies. A worm wheel is arranged on the edge of the rotary disc. A motor is arranged below the rotary disc. An output shaft of the motor is connected with a worm. Compared with the prior art, when inner parts in the switch cabinet explode accidentally, a circuit connecting the cabinet with the exterior is automatically cut off, and serious consequences are prevented from being generated.
Description
technical field [0001] The invention belongs to the field of electronic equipment, in particular to a switch cabinet with an isolating switch. Background technique [0002] The whole composed of substations of various voltages and transmission and distribution lines in the power system is called the power network, or power grid for short. It contains three units of transformation, transmission and distribution. The task of the power grid is to transmit and distribute electrical energy and to change the voltage. Whether it is power transformation, power transmission or power distribution, the utilization rate of cabinets in the power grid is very high. The cabinet can gather a lot of parts inside the cabinet, which can save space. It can also ensure the safety of the internal parts of the cabinet. [0003] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the su...
