Problems solved by technology

[0003] There are many electrical components installed in the distribution box. When it is working, a large current flows inside. There is a possibility of leakage in the existing distribution box. Especially in the rainy season, rainwater may penetrate into the distribution box. When flooding occurs during heavy rain, the water level may even submerge the distribution box. The large amount of rainwater entering the box may cause an electric leakage accident. When passers-by approach the distribution box, the electric leakage accident will be upgraded to electric shock accident
[0004] In the prior art, some use inert gas to reduce moisture, but this method cannot prevent rainwater from pouring back, and some use vacuum, but ignore the problem of heat dissipation in vacuum

Abstract

The invention provides an anti-electric leakage distribution box. The anti-electric leakage distribution box comprises a distribution box body, a heat dissipation device connected with the distribution box body, a vacuum pump arranged in the distribution box body, and an anti-electric leakage detection alarm system arranged in the distribution box body. By forming a vacuum isolation layer, the possibility of electric leakage caused by the fact that rainwater drips into the distribution box is reduced; the problem that the vacuum isolation layer cannot dissipate heat is solved by guiding out the heat from the box body and then dissipating the heat; and whether an electric leakage protection characteristic of an electric leakage protection switch in the distribution box can be detected automatically, and a detection result is fed back to a user in time, so that the detection is simple, convenient and rapid, and the user experience is effectively improved.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a leakage-proof distribution box. Background technique [0002] The distribution box is a general term for the power control center, which is the final equipment of the power distribution system. In the prior art, the shells of most of the distribution boxes are made of metal, and when they are installed outdoors, they need to bear the impact of direct sunlight and rain. [0003] There are many electrical components installed in the distribution box. When it is working, a large current flows inside. There is a possibility of leakage in the existing distribution box. Especially in the rainy season, rainwater may penetrate into the distribution box. When flooding occurs during heavy rain, the water level may even submerge the distribution box. The large amount of rainwater entering the box may cause an electric leakage accident. When passers-by approach the distribution box, th...
