Description

junction box

technical field

The utility model relates to the field of electric equipment, in particular to a junction box. the

Background technique

Existing substations are provided with a plurality of junction boxes outdoors for placing terminals, and the waterproof level of these junction boxes is level 2, that is, anti-drip and splash type II. This kind of junction box has the problem of water seepage and water leakage in thunderstorm weather with heavy precipitation. After the junction box is flooded, it is very easy to cause the terminal to be grounded or short-circuited, which may cause the equipment to malfunction or refuse to operate, and endanger the equipment in the substation. Safe and stable operation. the

In the prior art, two methods are used to solve the problem of water leakage in the junction box. The first method is to add waterproof sealing rubber strips to the junction box, so that the waterproof level of the junction box can be increased to level 5, which is the anti-spray type. It will not leak when it is sprayed with water. However, improving the waterproof level of the junction box will increase the cost of the junction box, and because the outdoor environment is relatively harsh, the waterproof sealing rubber strip will age rapidly, resulting in a decrease in waterproof capability. the

Another way is to strengthen the daily inspection of the substation, and if water seepage or leakage is found in the junction box, it will be dealt with quickly. However, frequent inspections increase the workload of substation operation and maintenance personnel, which is not conducive to the development of work. the
