Description

{WATERPROOF APPARATUS FOR DISTRIBUTING BOARD}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to an apparatus for preventing flooding of an electric cabinet, and more particularly, to preventing water from flowing into an inside of an electric cabinet through a vent hole provided at a lower end of the body.

In general, the switchboard is a device that supplies electricity to various indoor and outdoor electrical appliances including lighting.

The switchboard includes a main body in which a plurality of stabilizers and power distribution components such as various switches and breakers are incorporated; And a door that is pivotally openable and closable in front of the main body.

The power distribution parts such as a ballast and a switch, which are built in the main body of the switchboard, are heat generating parts that generate heat during operation. Therefore, when various electric devices are operated, internal air of the main body is heated to a high temperature, Electric parts such as electric wires are adversely affected.

Accordingly, a number of techniques have been proposed for discharging the internal air of the main body, which is heated through the heat generating parts of the power distribution board, to outside or actively cooling the inside of the main body through the cooling means.

In particular, the present invention relates to an electrical switchboard which is provided with a ventilation hole in a lower portion of the main body and is capable of supplying fresh air to the inside of the main body.

On the other hand, the power distribution parts embedded in the power distribution board are very vulnerable to water, so that when the power distribution board is flooded, most of the power distribution components are damaged, and fatal damage such as short circuit is caused.

Therefore, it is extremely desirable to install the switchboard safely in a place where flooding does not occur even during heavy rain in summer, but flooding may occur due to unexpected natural disasters.

The following Patent Document 1 discloses a lower open type distribution box having a flooding prevention function.

In the lower open type power distribution box of the patent document 1, the curtain for providing a closed space for only the power distribution board falls downward from the inside of the cabin only when flooded, and is supplied with pneumatic pressure. It is possible to completely seal the space, so that the air pressure inside the closed space is prevented from leaking to the outside, and the entire power distribution box is submerged by the pneumatic pressure in the closed state, and even when the power supply is interrupted, So that the flood prevention function is maintained.

Korean Registered Patent No. 10-1048583 (issued on July 12, 2011)

However, the lower open type power distribution box of the patent document 1 has a float sensor for detecting flooding, a means for raising and lowering the cover, a means for generating a pneumatic pressure, and the like, Therefore, it is difficult to apply it to a switchboard in practice.

Further, in the lower open type power distribution box having the flood prevention function of Patent Document 1, if a failure occurs in any of a large number of major constituent parts, there is a possibility that malfunction may be caused even though it is an expensive apparatus, so flooding can not be prevented.
