Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to an electrical cabinet with a reinforced grounding structure. Background Art

[0002] With the rapid development of society and economy, distribution cabinets are divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. They are the final equipment of the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are suitable for occasions with relatively dispersed loads and fewer circuits, while motor control centers are used in occasions with concentrated loads and more circuits. They distribute the power of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load. The installation requirements of the distribution box are that the distribution board should be made of non-combustible materials. Open distribution boards can be installed in production sites and offices with low risk of electric shock. Closed cabinets should be installed in processing workshops, foundries, forgings, heat treatment plants, boiler rooms, woodworking rooms, and other places with high risk of electric shock or poor working environments. In dangerous workplaces with conductive dust or the generation of flammable and explosive gases, enclosed or explosion-proof electrical facilities must be installed.

[0003] According to the application publication number: CN118040497A, a power distribution cabinet is provided, which involves a power distribution cabinet, the power distribution cabinet is provided with a protective component on the outside, a control component on the front, an exhaust component inside the power distribution cabinet, a drive component on the power distribution cabinet, the drive component is connected to the exhaust component, the drive component is connected to the two traction components respectively through two locking components, the two traction components are connected to the cleaning component, the two cleaning components are both arranged on both sides of the power distribution cabinet, and the power distribution cabinet is provided with an induction component and a fire extinguishing component; wherein, the power distribution cabinet includes a cabinet body, the control component is arranged on the front of the cabinet body, the back of the cabinet body is provided with two limit slots, the protective component is arranged in the two limit slots, a purification net is clamped on the cabinet body, the two sides of the cabinet body are respectively clamped with a first dustproof net, the two sides of the cabinet body are connected to the first electromagnet, the two cleaning components and the two traction components are respectively arranged on both sides of the cabinet body, the drive component is arranged on the cabinet body, and the induction component and the exhaust component are both arranged inside the cabinet body.
