[0032] Specifically, the shell 1 serves as a protective structure for the entire cabinet, providing a safe working environment for the internal electrical components, effectively preventing external objects or personnel from accidentally touching the internal live parts. The circuit breaker 3 is installed at the top of the shell 1 and is a key protection component in the circuit. When an overload, short circuit, or under-voltage fault occurs in the circuit, the circuit breaker 3 will automatically cut off the circuit to protect other electrical equipment from damage. The contactor 4 is located at the bottom of the circuit breaker 3 and is mainly used to control the on-off of the circuit. Through the action of electromagnetic force, the contactor 4 can make the contact closed or open, thereby achieving the control of starting, stopping, and forward and reverse rotation of the electrical equipment in the circuit. The fuse 5 is installed at the bottom of the contactor 4 and is a simple and effective short-circuit protection device. When a short-circuit fault occurs in the circuit, the fuse 5 melts rapidly, cutting off the circuit to prevent serious damage to the electrical equipment caused by short-circuit current. The inner insulation door 6 is fixedly installed on the front side of the shell 1, further enhancing the insulation protection of the internal electrical components. At the same time, the inner insulation door 6 is rotatably connected to multiple observation windows 7, which allow the operator to observe the working status of the internal electrical components without opening the cabinet door. The magnetic block one 8 fixedly connected to the rear left end of the observation window 7 is magnetically connected to the magnetic block two 9 fixedly connected to the rear left end of the inner insulation door 6, allowing the observation window 7 to be tightly closed, ensuring the sealing of the observation window 7 and facilitating the observation at any time.

The front side is clamped with a fine filter core 204, which further filters the tiny particles in the air to create a clean air environment inside the cabinet body. The cooling fans 205 are installed on the front side of the mounting frame 202. The two cooling fans 205 at the top and the two cooling fans 205 at the bottom rotate in opposite directions. When the cooling fans 205 are running, air convection circulation is formed. The cooling fans 205 at the top extract the hot air from the upper part of the cabinet body, while the cooling fans 205 at the bottom suck in the cold air from the outside. The exchange of cold and hot air allows the heat inside the cabinet body to be quickly dissipated. The cooling mesh 206 is located in front of the cooling fan 205, which protects the cooling fan 205 from being damaged by external objects and assists the uniform flow of air. The cooling components are firmly fixed by the fixing bolts 207 which pass through the cooling fan 205, the mounting frame 202 and the fixed plate 201 in turn. When the electrical control cabinet is running, the circuit breaker 3, the contactor 4 and the fuse 5 generate heat. The circulating cooling mechanism 2 starts in time to filter the air through the coarse filter screen 203 and the fine filter core 204, drive air circulation through the cooling fan 205, and assist heat dissipation through the cooling mesh 206.
