Description

Technical Field

[0001] This utility model relates to the field of switch cabinet technology, and specifically to a combined switch cabinet. Background Technology

[0002] A switchgear is a type of electrical equipment. External power lines first enter the main control switch inside the cabinet, and then enter the branch control switches. Each branch circuit is configured according to its needs. Examples include instruments, automatic control systems, motor magnetic switches, various AC contactors, etc. Some switchgear also have high-voltage and low-voltage compartments.

[0003] In order to facilitate disassembly and assembly, existing switchgear often uses a modular structure for the support frame inside the cabinet. It is pre-connected by a corresponding connection structure and then further fixed with bolts. However, bolt fixing requires disassembly and assembly, resulting in low assembly efficiency. Furthermore, when the bolts are located inside the corners of the cabinet, it will cause inconvenience to the operator and further affect the assembly efficiency. Therefore, there is an urgent need for a modular switchgear to solve the above problems. Utility Model Content
