Description

Technical Field

[0001] The utility model relates to the technical field of poles of vacuum circuit breakers, in particular to a pole used for vacuum circuit breakers. Background Art

[0002] There are two types of outdoor insulation sealing technologies (pole sealing) for vacuum interrupters on outdoor vacuum circuit breakers. One is to use unsaturated resin and silicone rubber materials to press them into a composite insulating cylinder twice, which is then placed in a vacuum interrupter and sealed with liquid silicone rubber. The other is to use pressure gel technology to place the vacuum interrupter in a mold and press it with epoxy resin material.

[0003] And in the application document with the publication number CN219497630U, a pole of a vacuum circuit breaker is mentioned. The utility model has a connection groove at the top of the connection rod, and a terminal rod is detachably fixed through the connection groove. After the wire and the connection terminal are fixed on the ground, the connection terminal is threadedly inserted into the terminal rod. When the connection terminal and the wire are installed in the air, the terminal is inserted into the connection groove, and the spring in the mounting hole of the side wall of the raised part pushes the positioning block to make it fit and insert it into the positioning hole, so that the terminal rod is fixed in the connection rod, and the positioning is squeezed from the side wall of the connection rod when disassembling. The rod is moved out of the positioning hole, and the wire is pulled upward at the same time to remove the terminal rod from the connecting groove. By arranging terminal rods and connecting rods that are easy to connect and disassemble, the convenience of connecting the pole with the wire at high altitude is greatly improved. At the same time, a support tube is fixed on the top of the mounting seat, and the support rod at the bottom end of the pole body is threadedly inserted into the screw hole opened in the top of the support tube, so that the mounting seat and the support tube support and install the pole body, which improves the stability of the pole. However, there are still certain defects that need to be optimized. The specific defects are as follows: the connection is prone to corrosion due to long-term use, and the pole body is prone to loosening. Utility Model Content

When the tightening force is small, the rotating block is rotated to rotate the threaded rod inside the threaded hole, so that the threaded rod extends toward the inside of the connecting sleeve and pushes the arc-shaped clamping block at the same time. At this time, the sealing silicone pad on the arc-shaped clamping block contacts and tightens the connecting block until the rotating block cannot be rotated. The device can adjust the degree of tightening, and the pole body can be separated from the mounting base, so as to be more convenient for maintenance, detection and replacement.

[0024] A connection port is provided on the mounting block 2, wherein the connection port passes through the bottom of the mounting block 2, so that the mounting block 2 can be fixed to the ground, the threaded rod 6 is threadedly connected to the threaded hole 5, so that the threaded rod 6 can rotate inside the threaded hole 5, the threaded rod 6 extends through the threaded hole 5 to the inside of the connecting sleeve 4 and is threadedly connected to the arc clamping block 8, so that the threaded rod 6 can be connected to the arc clamping block 8, the threaded hole 5, the threaded rod 6, the rotating block 7, the arc clamping block 8, and the sealing silicone pad 9 are each provided with two groups, so that the arc clamping block 8 can be fixed from both sides of the connecting block 10, and the connecting block 10 at the bottom of the pole body 11 extends to the inside of the connecting sleeve 4, so that the pole body 11 can enter the inside of the connecting sleeve 4.

[0025] The working process of the utility model is as follows: when using the pole of the vacuum circuit breaker, the base 1 of the device is first placed in the specified position, and then the bolt is passed through the connection port on the mounting block 2 to fix the base 1 in the specified position.
