Description

Technical Field

[0001] The invention relates to the technical field of switch cabinets, in particular to a switch cabinet with a protection function. Background Art

[0002] The switch cabinet is an electrical device. The external line of the switch cabinet first enters the main control switch inside the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. One or more low-voltage switchgear and related control, measurement, signal, protection, regulation and other equipment, the manufacturer is responsible for completing all internal electrical and mechanical connections, and a combination of structural components that are completely assembled together. The main function of the switch cabinet is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet mainly include circuit breakers, disconnectors, load switches, operating mechanisms, mutual inductors and various protection devices.

[0003] Most of the switch cabinets in the prior art adopt passive heat dissipation, which is achieved by opening heat dissipation holes on the switch cabinet. This not only makes it easy for dust to enter, but also has poor heat dissipation effect. The components inside the switch cabinet are prone to overheating and aging, which shortens the service life of the switch cabinet. Secondly, most of the switch cabinets in the prior art fix the wiring harness and electrical equipment inside. If they encounter impact or shaking, the wiring harness will fall or loosen, causing the line to catch fire. Impact or shaking of electrical equipment will cause multiple groups of electrical equipment to collide, resulting in damage to the electrical equipment. Summary of the invention
