Description

Technical Field

[0001] The utility model belongs to the technical field of switch cabinets, in particular to a switch cabinet line dividing device. Background Art

[0002] The busbar refers to the copper or aluminum bar that connects the main switch in the cabinet and the switches in each branch circuit in the power supply system. The surface is insulated and its main function is to serve as a conductor. After searching, the patent with application number 201820928366.9 discloses a busbar tapping device for high-voltage switch cabinet, including a slot, a positioning slot, a positioning bar, a copper plate and a threaded hole. The slot is opened on the upper end face of the busbar, the copper plate is assembled in the slot, the positioning slot is opened on the rear end face inside the slot, and a positioning bar is assembled in the positioning slot. The positioning bar is fixed to the rear end face of the copper plate, and the threaded hole is opened on the upper end face of the copper plate.

[0003] However, during actual use, the applicant discovered that the copper plate inserted inside the busbar is limited in the busbar by an insulating plate, and the insulating plate is fixed by inserting the lower end into a strip groove opened at the top of a support. This single insertion method makes it easy for the insulating plate to loosen and fall off from the strip groove, and then the copper plate will easily detach from the busbar after losing the limiting blockage of the insulating plate. In view of this, we propose a switch cabinet distribution device. Utility Model Content
