Problems solved by technology

Due to the large amount of equipment in the electrical cabinet, a large amount of heat will be generated during use, mainly relying on the external environment to cool down and dissipate heat through the cooling holes on the cabinet. The cooling effect is average, and there are certain safety hazards in long-term use.
In addition, when installing the electrical protection panel, it is necessary to pre-embed multiple channel steels on the ground. The multiple channel steels form a rectangular trough, and then place the electrical protection panel in the rectangular trough and fix it with bolts or welding. The installation is more troublesome.
Therefore, the existing technology has the problem of poor heat dissipation

Description

technical field [0001] The invention relates to a protection panel, in particular to an electrical protection panel. Background technique [0002] A large number of electrical protection panels are required in hydropower stations, and some electrical protection devices are installed in the electrical protection panels to connect the power supply to the load for the purpose of protection. Due to the large amount of equipment in the electrical cabinet, a large amount of heat will be generated during use, mainly relying on the external environment to cool down and dissipate heat through the cooling holes on the cabinet. The cooling effect is average, and there are certain safety hazards in long-term use. In addition, when installing the electrical protection panel, it is necessary to pre-embed multiple channel steels on the ground. The multiple channel steels form a rectangular trough, and then place the electrical protection panel in the rectangular trough and fix it with bolt...
