Abstract

The present invention discloses a high-voltage power distribution switchgear cabinet. The cabinet comprises a cabinet body, a protective cover, a relay and a terminal chamber. The protective cover and the relay are arranged on the cabinet body; the terminal chamber is formed at the upper right corner of the cabinet body; a trolley is arranged below the terminal chamber; a handle and an observation window are arranged at a front end of the trolley; the handle is fixedly connected to the trolley; the observation window is connected to the trolley in a sealing way; a circuit breaker is mounted at one side of the trolley; the trolley is drive-connected to the circuit breaker; a contact box and a current transducer are arranged at one side of the circuit breaker; the contact box and the current transducer are respectively and electrically connected to the circuit breaker; an insulator is arranged on the contact box; and a grounding switch is arranged below the current transducer. The high-voltage power distribution switchgear cabinet is secure and reliable for operation and high in running stability, and manual operation strength can be reduced.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to a high-voltage power distribution switch cabinet. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. The load provides protection, monitoring and control. The first-level power distribution equipment is collectively referred to as the power distribution center. They are centrally installed in the substation of the enterprise to distribute pow...
