Description

Technical Field

[0001] The utility model relates to the field of switch cabinets, in particular to a switch cabinet which is easy to maintain. Background Art

[0002] The switch cabinet is an electrical equipment, including the shell, distribution board and various electrical components and indicating instruments. The external line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage room switch cabinets, with high-voltage busbars, such as power plants, etc., and some are also equipped to ensure low-frequency load shedding of major equipment.

[0003] When a common switch cabinet fails, the cabinet door can usually only be opened for maintenance. However, the space inside the cabinet is narrow and the operating space is limited, which is inconvenient for maintenance personnel to perform maintenance. Secondly, the common switch box is fixed to the ground with cement. Once the pouring is completed, the direction of the switch box cannot be changed. If one side of the switch box door is blocked by debris, the direction cannot be adjusted properly, affecting the operation during maintenance.
