Low voltage bus bar groove branch outgoing line case

Abstract

The invention relates to a branch lead box of low-voltage bus duct for connecting a bus connection box and a cable in a low-voltage power transmission and distribution circuit. The branch lead box of low-voltage bus duct comprises a box body made of an insulating material, a wire inlet hole provided on the front end of the box body for connecting the connection box, a wire outlet hole provided on the rear end of the box body for connecting the cable, multi-phase conductive terminal rows fixed in the box body side by side, and mounting holes formed on the front and the rear ends of the conductive terminal rows and respectively connected with a transition row of the connection box and the cable head. The branch lead box of the invention can be connected with the cable and the connection box with good insulating performance thus facilitating the reasonable arrangement of the construction schedule of bus duct products.

Description

technical field [0001] The invention relates to a low-voltage busway branch outlet box used for connecting a busbar plug-in box and cables in a low-voltage power transmission and distribution line. Background technique [0002] Today, with the continuous improvement of urban power supply systems, busway products are widely used. The plug-in box is the main branch feed mode of the busbar. The following problems will occur during installation and use: 1. Due to the tight supply period and the long production cycle of the plug-in box, the manufacturer generally supplies the busway first. As a result, the busway was installed and the cables were put in place, but the cables could not be connected because the plug-in box did not arrive. Since the cable is connected with accessories such as cable heads and wiring pipes, it is difficult to connect it to the plug-in box, and the progress of installation and construction is slow. Therefore, if the cable connection is performed after...

Problems solved by technology

The plug-in box is the main branch feed mode of the busbar. The following problems will occur during installation and use: 1. Due to the tight supply period and the long production cycle of the plug-in box, the manufacturer generally supplies the busway first

As a result, the busway has been installed and the cables have been put in place, but the cables cannot be connected because the plug-in box has not arrived

Since the cable is connected with accessories such as cable heads and wiring pipes, it is difficult to connect it to the plug-in box, and the progress of installation and construction is slow. Therefore, if the cable connection is performed after the plug-in box is in place, the progress of the project will be affected.

2. Maintenance is inconvenient. The plug-in box breaks down during use. Since the cable has been fixed by the wiring tube and the plug-in box, it is necessary to disassemble the wiring tube first, then remove the cable connector, and finally plug in the plug-in box for maintenance.

Long maintenance intervals resulting in extended outages
