[0002] The distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box) and metering cabinet (box). It is the final equipment of the distribution system. The distribution cabinet is a general term for the motor control center. The distribution cabinet is used in occasions with relatively dispersed loads and fewer circuits. Since the distribution cabinet is mainly responsible for the distribution of electric energy, its own insulation performance is particularly important.

[0003] The utility model with reference application number CN202320216770.4 discloses a distribution cabinet body with plastic insulating parts, and its technical solution is: it includes a distribution cabinet body, a cabinet door is provided on one side of the distribution cabinet body, a slot is opened inside the distribution cabinet body, and an anti-electric shock mechanism is provided on one side of the cabinet door; the anti-electric shock mechanism includes a damping shaft, the damping shaft passes through the cabinet door, an insulating handle is fixedly provided at one end of the damping shaft, and a gear is fixedly provided on the other end of the damping shaft. The beneficial effect of a distribution cabinet body with plastic insulating parts is: the rack is driven to move to the left through the rotation of the gear, and at the same time the rack drives the pin to disengage from the inside of the slot, and the movement of the insulating triangular block drives the movable conductive column to disengage from the upper and lower connecting conductive columns, and the circuit is disconnected when the cabinet door is opened to prevent leakage, and the metal connecting block is separated from the fixed connecting block, so that the circuit inside the distribution cabinet body is disconnected to prevent someone from accidentally closing the power switch and causing electric shock to the maintenance personnel.

Since the ground is in a vibrating state for a long time, it is easy for the internal insulation structure to loosen and cause hidden dangers. At the same time, when the cabinet door is opened without maintenance, the cabinet body cannot be insulated. Utility Model Content
