Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and more specifically, to a main busbar lapping device for a low-voltage power distribution cabinet. Background Art

[0002] A low-voltage power distribution cabinet is a device used for power distribution and control, usually used in a low-voltage power grid and is an indispensable part of the power system. It not only ensures the safe distribution of electricity but also provides necessary protection measures to maintain the stability of the entire power system.

[0003] Currently, when the main busbar of an existing low-voltage power distribution cabinet is lapped with a connecting busbar, holes are usually drilled in the main busbar and the connecting busbar first, and then they are connected and fixed by bolts and nuts. To ensure the normal transmission of electricity, the main busbar and the connecting busbar need to be disassembled and overhauled frequently. When disassembling and overhauling, it takes a lot of time to disassemble the bolts and nuts, which is rather troublesome. In view of this, we propose a main busbar lapping device for a low-voltage power distribution cabinet. Content of the Utility Model

When connecting the connection busbar to the main busbar 2, press the other end of the pressure lever 307 towards the mounting plate 301. One end of the pressure lever 307 pulls the link rod 306 outwards to drive the guide rod 304 and the pressure plate 303 to move towards the other side of the fixed frame 302, and at the same time compress the spring 305.

[0021] Furthermore, as Figure 2As shown in the figure, a clamping cavity A3041 is provided at one end of the guide rod 304. One end of the connecting rod 306 extends into the clamping cavity A3041 and is rotatably connected to the inner walls on both sides of the clamping cavity A3041 through a rotating shaft; a clamping cavity B3071 is provided at one end of the pressure rod 307.

The connection line row and the main bus 2 can be disassembled and assembled at the same time and independently, further meeting the actual maintenance requirements.

[0023] Working principle: This embodiment provides a main busbar lapping device for a low-voltage power distribution cabinet. When in use, rotate the C-shaped frame 3081 towards one side of the power distribution cabinet body 1. The C-shaped frame 3081 drives one end of a number of pressure rods 307 to rotate towards one side of the mounting plate 301 through the insertion rod 3082. The middle part of the pressure rod 307 rotates around a rotating shaft in the clamping cavity C3021.
