Description

Technical Field

[0001] The utility model specifically relates to the technical field of switch cabinets, in particular to a replaceable modular switch cabinet. Background Art

[0002] A switch cabinet is a type of electrical equipment. External wiring in the switch cabinet first enters the main control switch inside the cabinet, then flows to the sub-control switches. Each branch is configured as needed, such as for instruments, automatic controls, motor magnetic switches, and various AC contactors. Some switch cabinets also have high-voltage and low-voltage compartments, and are equipped with high-voltage busbars, such as in power plants. Some also have low-frequency load shedders to protect key equipment.

[0003] Chinese Utility Model Publication No. CN 209929839 U discloses a switch cabinet body and switch cabinet. The switch cabinet includes a cabinet body, which includes a busbar compartment and a top cover located on the top of the cabinet body and extending forward and backward. The busbar compartment is provided with three-phase busbars, which are connected to three-phase busbars. The top cover is provided with bushings for the three-phase busbars to pass through. The three-phase busbars are arranged in a "pin" shape to form a corresponding air insulation distance between any two adjacent phase busbars.

[0004] The above-mentioned switch cabinet body and switch cabinet are integrated settings, which are more troublesome when installing, disassembling and replacing all modules. All the modules inside cannot be taken out and replaced again. For this reason, we provide a replaceable modular switch cabinet, which is slidably connected to the inner carrier frame on the inner side of the switch cabinet, and the modules are installed on the inner carrier frame. The modules can be fixed on the inner carrier frame relatively quickly, which is convenient for replacement and installation. The entire inner carrier frame can also be pulled out and replaced with the inner carrier frame carrying the new module. It is more convenient to use and effectively compensates for the above-mentioned problems. Utility Model Content
