Problems solved by technology

[0003] The existing compact vacuum fixed switch does not have external protection equipment, which will seriously affect the work of the compact vacuum fixed switch in rainy and snowy weather, and will cause some metal materials to corrode, seriously affecting the service life of the compact vacuum fixed switch. At the same time, the air The dust will also affect the interior of the compact vacuum fixed switch, which is not conducive to heat dissipation
