[0002] The control cabinet is a combination of switchgear, measuring instruments, protective electrical appliances and auxiliary equipment assembled in a closed or semi-closed metal cabinet or on a screen according to the electrical wiring requirements. Its layout should meet the requirements for normal operation of the power system, be easy to repair, and not endanger the safety of people and surrounding equipment. At present, various electrical components are installed inside the electrical control cabinet.

[0021] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error.

[0023] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0024] Combined with Figure 1 and 2 A heat dissipation and dustproof electrical control cabinet of this embodiment includes a cabinet body 1, and a plurality of heat dissipation holes are arranged on the side of the cabinet body 1. A mesh cloth 2 covering the plurality of heat dissipation holes at the same time is also arranged on the side of the cabinet body 1. External air first passes through the mesh cloth 2 and then passes through the heat dissipation holes. A mesh cloth unwinding mechanism 3 and a mesh cloth winding mechanism 4 are respectively arranged at both ends of the mesh cloth 2.
