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

Abstract

The invention discloses an electric leakage protection device, which comprises an installation cabinet body, an installation bracket and an electric leakage protector. The installation bracket is fixed on the installation cabinet, a protective cover is fixed on the installation bracket, and a Leakage protector, the two ends of the protective cover are fixed with threading pipes, the upper end of the installation cabinet is fixed with two symmetrical installation frames, and photovoltaic panels are installed on the two installation frames, and the installation A support frame is fixed on the inner top wall of the cabinet. The invention detects the humidity in the installation cabinet through the humidity detection device. When the humidity exceeds the limit value, the humidity controller controls the heating belt to heat the installation cabinet, thereby increasing the evaporation speed of water vapor in the installation cabinet, and cooperates with the cooling fan Then the water vapor can be discharged through the dust-proof net, thereby reducing the humidity value in the installation cabinet, better preventing the equipment from being damp and leaking electricity, and ensuring the normal use of the leakage protector.

Description

technical field [0001] The invention relates to the technical field of leakage protection, in particular to a leakage protection device. Background technique [0002] In many outdoor point-of-use equipment, leakage problems are prone to occur due to the influence of the external environment and air humidity. Therefore, leakage protection devices need to be installed. The general leakage protection devices are mainly leakage protectors; [0003] When the leakage protector is used, it is inconvenient to protect the end of the line. If it is affected by external water vapor, it is easy to affect the normal use of the leakage protector. At the same time, the equipment in the cabinet where the leakage protector is installed is vulnerable to moisture leakage. The impact of the installation of the cabinet makes the probability of electric shock higher, and the leakage protection of a single leakage protector is not convenient to fully ensure the overall leakage protection. Due to t...
