Problems solved by technology
[0003] When the leakage protector is used, it is not convenient to protect the line ends. If it is affected by external water vapor, it will easily affect the normal use of the leakage protector. The impact of the influence of the installation cabinet makes the electric shock probability of the installation cabinet higher, and the leakage protection of a single leakage protector is not convenient to fully guarantee the overall leakage protection. Due to the heat dissipation requirements of the installation cabinet, multiple cooling slots or cooling holes are generally designed on the cabinet. , when rainwater occurs, it is easy to enter the inside of the installation cabinet from the cooling hole, which is not conducive to the waterproof performance of the leakage protector, and it is easy to make the equipment damp and cause leakage

The invention discloses an electric leakage protection device and method. The device comprises an installation cabinet body, an installation support and an electric leakage protector, the installationsupport is fixed on the installation cabinet body, a protection cover is fixed on the installation support, the electric leakage protector is installed in the protection cover, and threading pipes are fixed at two ends of the protection cover. Two symmetrical mounting frames are fixed to the upper end of the installation cabinet body, photovoltaic panels are mounted on the two installation frames, and a supporting frame is fixed to the inner top wall of the installation cabinet body. The humidity in the installation cabinet body is detected through a humidity detection device, when the humidity exceeds a limit value, a humidity controller controls a heating belt to be powered on to heat the installation cabinet body, so that the evaporation speed of water vapor in the installation cabinetbody is increased, and the water vapor can be discharged through a dust screen in cooperation with operation of a cooling fan, so the humidity value in the installation cabinet body is reduced, the situation that equipment is affected with damp and leaks electricity is better prevented, and normal use of the electric leakage protector is guaranteed.
Description
technical field [0001] The invention relates to the technical field of leakage protection, in particular to a leakage protection device and method. Background technique [0002] Among many outdoor equipment, due to the influence of the external environment and air humidity, leakage problems are prone to occur, so it is necessary to install leakage protection devices, and the general leakage protection devices are mainly leakage protectors; [0003] When the leakage protector is used, it is not convenient to protect the line ends. If it is affected by external water vapor, it will easily affect the normal use of the leakage protector. The impact of the influence of the installation cabinet makes the electric shock probability of the installation cabinet higher, and the leakage protection of a single leakage protector is not convenient to fully guarantee the overall leakage protection. Due to the heat dissipation requirements of the installation cabinet, multiple cooling slots...
