An electrical cabinet with segmented self-locking and fixed circuit units

Abstract

The invention discloses a sectional self-locking fixed electric cabinet of a circuit unit which includes: a split plate frame, a protective outer box, a heat dissipation ceiling, a cabinet door, a lock head, and indicator light. The shell of the plate splitting frame is welded and fixed on the rear end of the protective outer box. A heat dissipation ceiling covers the upper end of the heat dissipation hole on the top of the protective outer box, A left side leaf plate of that cabinet door is fixed with the lock head and is fixed at the front end of the protective out box, The indicator light is secured to the top of the cabinet door and fits into the side slots at the front of the protective outer compartment. In summary, after the invention is improved, the components are dispersed to reduce the overweight condition, so that the circuit bottom plate is easy to install, and the anti-falling eccentric wheel is arranged so that the plug connection between the boards is compact, thereby improving the convenience of the circuit reconstruction and maintenance of the electric cabinet in the future.

Description

technical field [0001] The invention relates to an electrical fixing cabinet, in particular to an electrical cabinet with segmented self-locking fixed circuit units. Background technique [0002] Electrical cabinets are widely used in mechanical automation and power systems to fix some complete sets of devices such as circuit breakers and contactors. Due to their strong customizability and the ability to independently transform electrical cabinets according to power requirements, they are widely used. Some problems are often encountered when installing complete sets of electrical components, especially some high-power equipment: [0003] In order to meet the power requirements, the weight of circuit breakers and contact switches inside some high-power electrical cabinets will also increase. Generally, circuit breakers are installed on the top to facilitate wiring. During the installation process, two people are required to work together. Bolts fix it on the inner plate, and...

Problems solved by technology

[0003] In order to meet the power requirements, the weight of circuit breakers and contact switches inside some high-power electrical cabinets will also increase. Generally, circuit breakers are installed on the top to facilitate wiring. During the installation process, two people are required to work together. Bolts fix it on the inner plate, and because the circuit breaker is heavy and the resistance load of the toggle switch is large, it is not suitable for fixing it with a bracket, and the bracket is easy to affect its heat dissipation, and the machine cannot be used due to the different needs of users. Instead of manual assembly, it is very troublesome to install
