Embodiment Construction

[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0022] The invention provides a junction box, such as figure 1 and 2 As shown, the junction box includes a box body 10 and a rainproof portion 20, the rainproof portion 20 is arranged on the top of the box body 10, and the rainproof portion 20 extends from the rear side of the box body 10 to the front side of the box body 10. And protruding from the front side.

[0023] The junction box of the present invention includes a rainproof part 20, which is arranged on the top of the box body 10 and extends out of the box body 10 to block rainwater and prevent rainwater from directly splashing on the box body 10, which can effectively Avoid water seepage, water leakage, etc. of the box body 10, thereby preventing terminal grounding or short-circuiting cau...

Abstract

The invention provides a junction box comprising a box body and a rainproof portion. The rainproof portion is disposed on the top end of the box body. The rainproof portion extends from the rear side of the box body to the front side of the box body, and protrudes from the front side. The junction box of the invention comprises the rainproof portion, and the rainproof portion is disposed on the top end of the box body and extends out of the box body, so as to shield rainwater and prevent rainwater from dropping on the box body directly. Thus, water seepage and leakage of the box body are effectively prevented, and further, terminal grounding or short-circuiting caused by water flowing into the box body is prevented, and safe and stable operation of devices in a transformer station is ensured.

Description

technical field [0001] The present invention relates to the field of electric equipment, more specifically, to a junction box. Background technique [0002] 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 misoperation or refusal of the equipment, and endanger the equipment in the substation. Safe and stable operation. [0003] 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...
