Description

A bus-bar array structure for an distribution switchboard}

The present invention relates to a busbar arrangement structure for a switchboard, and more particularly, a bus busbar drawn in from the outside is introduced into an intermediate portion of a switchboard case and then connected to a charity busbar of a switchboard unit arranged up and down, thereby providing a more stable electrical connection. It relates to a busbar arrangement structure for the switchboard to be made.

In general, a switchboard is a device in which various units such as a main circuit breaker, an auxiliary wiring breaker, and an earth leakage breaker are installed in the casing, and the units are electrically connected to each other. It is a device used to switch on and off the power supply at the same time as supplying to each element of.

The switchboard is provided with a plurality of bus-bars for distributing power supplied from the outside by electrically connecting the respective units, and one side of the busbar is connected to the output terminal of the main circuit breaker. Busbar booth to induce electric power

The bar is composed of a charity busbar that is connected to the busbar bus bar and supplies the distributed power to each of the auxiliary wiring breaker and the earth leakage breaker, and the charity busbar is provided with a connector for receiving power by connecting to the busbar busbar.

In addition, the switchgear is designed differently according to the power demand of the building, the main circuit breaker should use a product of the capacity according to the power demand, the main circuit breaker is usually the gap between the size of the case and the output terminal according to the capacity This has different characteristics from each other. Therefore, in the prior art, the spacing between busbar busbars was also changed according to the spacing between output terminals when designing switchboards, which causes the position of the connector provided in the own busbar to be changed. Since it was necessary to use other charity booth bar, there was a problem that the standardization of the charity busbar was impossible.

In addition, there has been a problem that it is difficult to install a plurality of units in the switchgear case as busbar busbars introduced into the switchgear case are pulled from the rear upper side or the rear lower side of the switchgear case.

Therefore, the present invention was devised to solve the above problems, and an object of the present invention is to make the bus bus bar drawn from the outside connected to the charity bus bar of the switchgear unit arranged up and down after being drawn into the middle part of the switchgear case. And easy electrical connection.

In order to achieve the above object, the present invention provides a bus bar arrangement structure in which a plurality of switchboard units are coupled up and down in a case in which a busbar bus is inserted to connect the charity busbars of the switchboard unit with the busbar busbars. The busbar busbars introduced into the switchgear case are arranged to be connected to the charity busbars of the switchgear units positioned up and down after being drawn into the middle of the switchgear case.

Accordingly, the busbar arrangement structure of the switchboard according to the present invention has an effect of making the bus busbar drawn in from the outside into the middle part of the switchboard case and then connected to the charity busbars of the switchboard unit arranged up and down to make the electrical connection more stable. have.

In addition, when the switchgear case has front and rear opening and closing doors and a plurality of switchgear units are installed in the front and rear positions, one of the switchgear cases can be connected to a busbar bar that is connected to the switchboard unit to a busbar busbar which is introduced into the middle of the switchgear case. There is an effect that can be easily connected to a plurality of switchboard units installed in.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, and in describing the present invention, if it is determined that the related well-known technology may blur the gist of the present invention, the detailed description thereof will be omitted. do.

According to the present invention, as shown in FIG. 1 or 2, a plurality of switchboard units 300 are vertically coupled to the switchboard case 200 in which the busbar busbar 100 is inserted, thereby providing a charity busbar of the switchboard unit 300. In the busbar arrangement structure for the switchboard, which is connected to the busbar busbar 100, the busbar busbar 100 introduced into the switchboard case 200 is drawn into the side surface of the switchboard case 200. And then arranged so as to be connected to each of the charity busbar 400 of the switchgear unit 300 positioned up and down.

Charity busbar 400 is coupled to the busbar busbar 100 through a connector.

3 is a bus bar 100 having a switchboard case 200 having an opening / closing door 220 continuously arranged from side to side in a different embodiment according to the present invention. It shows the state of retraction.

This allows the switchboard units 300 provided to the plurality of switchboard cases 200 to be electrically connected to each other through the bus busbar 100 drawn into one side.

4 is a further embodiment according to the present invention, the opening and closing door 220 is installed in front and rear of the switchboard case 200, a plurality of switchboard unit 300 is installed up and down inside the switchboard case ( A bus bus bar 100 is drawn in the middle portion of the side surface of the 200 and is connected to the charity bus bar 400 of the switchboard unit 300.

This can connect the charity busbars 400 connected to the plurality of switchboard units 300 without bending or modifying the busbar busbar 100 drawn into one line.

In addition, the busbar bus 100 is inserted into the middle of the switchboard case 200 arranged in a plurality of left and right, and the charity busbar 400 is connected to the busbar busbar 100 and the switchboard unit 300. It will be possible to combine.

1 is a front main part showing a bus bar arrangement structure according to the present invention,

2 is a side cross-sectional main view of FIG. 1;

3 is a front main view illustrating a process in which a busbar bus is drawn in a state where switchboard cases are arranged left and right as another embodiment according to the present invention;

FIG. 4 is a side sectional view showing a process in which opening and closing doors are installed in front and rear sides of a switchboard case and busbars are inserted into a middle portion thereof according to another embodiment of the present invention.
