Abstract
The present invention relates to a busbar arrangement structure for switchboards.
In the present invention, a bus bar arrangement structure for a switchgear bus bar structure in which a plurality of switchgear units are coupled up and down in a case in which a bus bus bar is inserted to connect a charity bus bar of the switchgear unit with the bus bus bar is provided. After the busbar bus 100 is drawn into the middle portion of the switchboard case 200, the busbar bar 100 is arranged to be connected to the charity busbars 400 of the switchboard unit 300 positioned up and down.

Description
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.
