The invention discloses a novel safety protection device suitable for electrical equipment, and relates to the technical field of electrical equipment. The novel safety protection device suitable for the electrical equipment comprises a box body and a box door, an isolation layer is fixedly connected to the interior of the box body, a frequency converter is fixedly connected to the position, located in the isolation layer, of the inner wall of the box body, a groove is formed in the bottom of the box body, and a cooling fan is fixedly connected to the interior of the groove. When the frequency converter works, a large amount of heat is generated, the heat dissipation fan drives airflow to dissipate heat of the frequency converter, and meanwhile the heat dissipation fan drives hot airflow heated by the heater to flow in the box body, so that the temperature near the box body is increased, and the relative humidity near the box body is reduced.
Description
technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a novel safety protection device suitable for electrical equipment. Background technique [0002] Various mines such as coal mines, iron mines, metal mines and non-metallic mines are the lifeblood of the national economy, and coal mines are the main provider of national energy. And communication equipment, lighting equipment, and the temperature and humidity environment of the equipment is very complex and harsh, whether the electrical equipment can run dry has a great impact on safety, especially the requirements for the safe operation of power supply and electrical are getting higher and higher, which is the normal production of mines, Important technical guarantee for safe production and avoiding major accidents; [0003] There are many electrical equipment in mines, tunnels, civil air defense and underground projects, such as various types of high and low voltag...
