Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a switch cabinet which is convenient for maintenance. Background Art

[0002] The components within a switchgear cabinet primarily include circuit breakers, disconnectors, load switches, operating mechanisms, mutual inductors, and various protective devices. Due to the limited space within the cabinet, maintenance is inconvenient. Patent document CN216699133U discloses a switchgear cabinet designed for easy maintenance. The cabinet mechanism comprises a switchgear body and a door. One side of the switchgear body is open, and the door is pivotally connected to the open side of the switchgear body. The telescopic mechanism comprises a servo motor, a first ball screw, a second ball screw, a sliding assembly, and a mounting box. The servo motor is connected to one side of the switchgear body. One end of the first ball screw is mounted on the servo motor output shaft, extending through the switchgear body. One end of the second ball screw is connected to the other end of the first ball screw. When a main control switch malfunctions and requires maintenance, the telescopic mechanism facilitates the movement of the main control switch in and out of the switchgear cabinet. The cabinet exterior offers good lighting and ample operating space, making it easier for maintenance workers to perform repairs.

[0003] This method of installing various devices in the cabinet on a telescopic structure that can be moved out of the switch cabinet makes the arrangement of various cables more complicated. The main problem is that the cables must be long enough, which is wasteful and there is a risk of cables falling off. It is obviously not practical. Based on this, the existing switch cabinet structure has the problem of inconvenient maintenance and needs further improvement. Utility Model Content
