Abstract

The invention relates to the technical field of draw-out switch cabinets, and discloses a device for preventing wrong insertion of a drawer of a low-voltage draw-out switch cabinet. The rear surface of the drawer is fixedly connected with a positioning column, the left end of the positioning column is fixedly connected with a rubber layer, the rear side of the drawer is provided with a sliding groove, and the front and rear surfaces of the longitudinal rod groove of the sliding groove are provided with fixed grooves, and the interior of the sliding groove is slidably connected with The slider, the right side of the slider is fixedly connected with a positioning block. The power low-voltage withdrawable switch cabinet drawer anti-insertion device protects the positioning column and the positioning block through the cooperation of the first spring and the rubber layer, and the impact force of the positioning block is obtained through the elasticity of the first spring and the rubber layer. Therefore, to a certain extent, the impact force can prevent the positioning column and the positioning block from being damaged.

Description

technical field [0001] The invention relates to the technical field of withdrawable switch cabinets, in particular to an anti-insertion device for a drawer of a low-voltage withdrawable switch cabinet of electric power. Background technique [0002] The existing feeder drawers of different capacities on the withdrawable low-voltage switchgear have the same size, and the drawers of the same size on the low-voltage switchgear are interchangeable. On-site customers often only pay attention to the size of the drawer and ignore the capacity of the drawer, resulting in Wrong insertion of drawers of different capacities. For example, sending a drawer with a capacity of 400A into a drawer with a capacity of 630A will cause a short circuit between phases of the circuit; sending a drawer with a capacity of 630A into a drawer with a capacity of 400A will cause phase loss, which will seriously affect the power supply of the shadow circuit. and load life. [0003] According to the above...
