Description

Power Distribution Board {POWER DISTRIBUTION PANEL}

The present invention relates to a distribution panel in which a wiring breaker and a power electric device are installed. More specifically, the heat inside the enclosure can be smoothly discharged to the outside by natural exhaust without installing a separate heat dissipation device. It's about distribution boards.

In general, a distribution panel is provided with a circuit breaker, which is a switch for each branch circuit, in a branched circuit from a trunk line to each branch circuit.

The distribution panel in a house is a simple arrangement of fixed circuit breakers, which are cutout switches, but in buildings, at least each floor has a steel distribution panel in the wall and complete doors.

When checking, repairing or remodeling wiring in a room, the branch switch of the room can be cut off at the distribution panel to cause a power failure. Old-fashioned knives switches with packaged fuses are installed in each branch circuit. More advanced ones use tumbler switches and plug type fuses.

Such a distribution panel may be classified into a buried distribution panel in which the distribution panel is embedded in a wall and an exposed distribution panel installed outside the wall, depending on the type of installation.

13 and 14 illustrate such a conventional distribution board and its configuration and operation relationship are as follows.

As shown in Figure 13 and 14, the conventional distribution panel has a rectangular cuboid-type housing with an open front, a door that is installed to be opened and closed on the open front of the enclosure, and is mounted on the inner surface of the enclosure and the front It includes a mounting plate on which electrical equipment such as a switch for disconnecting wires is installed.

The enclosure is made of a metal plate to serve to protect the electrical equipment installed therein, the door is to allow the user to open or close the enclosure, the installation plate into the interior of the enclosure It serves to provide a place where the electrical equipment is installed.

However, the above-described conventional techniques have the following problems.

The distribution panel is generally operated with the door closed and the enclosure sealed, and heat generated by the electric device itself is not discharged from the interior of the enclosure to the outside, and is accumulated inside the enclosure to There was a problem of raising the internal temperature.

As such, when the internal temperature of the enclosure of the distribution panel is increased, there is a problem of causing deterioration of the electrical apparatus or distribution line installed in the distribution panel or causing malfunction of the electrical apparatus itself.

In addition, when the temperature difference between the inside and the outside of the cabinet of the distribution panel increases, condensation may occur in the interior of the enclosure, causing a short circuit in the electrical apparatus or causing corrosion of the distribution panel itself.

Therefore, there is an urgent demand for the development of a technology for properly discharging the heat generated in the conventional distribution panel.

Korean Laid-Open Patent Publication No. 2011-0017338 "Distribution board and box manufacturing method of the distribution board for this" 2011. 02. 21.

Accordingly, the present invention has been made to solve the conventional problems as described above,

An object of the present invention is to provide a simple structure that allows the heat inside the enclosure to be smoothly discharged to the outside by natural exhaust without installing a separate heat dissipation equipment, and by introducing the outside air into the inside of the enclosure The discharge is made more smoothly and stably, and an air flow path is formed inside the door to generate a pressure drop in the hot air induction hole so that the hot air is discharged more smoothly through the hot air induction hole. It is to provide a distribution panel to be insulated so that the occurrence of condensation inside the enclosure by the temperature difference between the inside and outside of the enclosure smoothly.
