Therefore, it is necessary to design a busbar connection mechanism for high-voltage switchgear. Utility Model Content

[0005] This utility model provides a busbar connection mechanism for high-voltage switchgear, which aims to solve the problem that currently only the clamping position can be adjusted, but the position where it is inserted into the rectangular clamp body is difficult to seal, and dust easily accumulates inside.

The upper and lower sides of the side push plate are inserted and restricted to the inside of the groove. The other two sides of the busbar are clamped by the spring telescopic rods on both sides. The spring telescopic rods naturally clamp the busbar and close the annular groove. Rotating the knob causes the threaded cylinder to rise and fall, clamping the two overlapping busbars and fixing the inserted busbar.

The extension directions of the threaded cylinders on both the upper and lower sides are towards the center position inside the clamping frame. The second extrusion plate allows the busbar to be smoothly inserted into both sides of the clamping frame and then initially clamped by the first extrusion plate.

[0014] Preferably, a transparent sealing plate is connected to the opening of the fixed frame. A hinge is provided between one side of the transparent sealing plate and the fixed frame. The transparent sealing plate is rotatably connected to the fixed frame through the hinge.

[0018] 2. The rectangular socket is designed to accommodate the insertion of the busbar and can be naturally adjusted to fit the four sides of the busbar.
