Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Example 1

As shown in fig. 1-4, the novel outdoor high-voltage vacuum circuit breaker comprises a vacuum circuit breaker body 5 and a conductive plate 3 arranged on one side of the vacuum circuit breaker body 5, and further comprises an extension part 6 arranged on one side of the conductive plate 3 on the vacuum circuit breaker body 5 and a conductive binding post 4 arranged on the top of the vacuum circuit breaker body 5, wherein the extension part 6 is provided with a winding device 1 and a clamping groove for accommodating the winding device 1, the winding device 1 comprises an upper shell 7, a lower shell 8 and a rotating mechanism 17, a through hole 11 is arranged at the joint of the front sides of the upper shell 7 and the lower shell 8 and serves as a wire outlet, and two through holes 11 are arranged at the joint of the rear side parts of the upper shell 7 and the lower shell 8 and serve as wire inlet ends. That is, the through hole 11 is formed by assembling the upper casing 7 and the lower casing 8 into a complete hole, and both the upper casing 7 and the lower casing 8 are half notches.

Furthermore, the upper shell 7 and the lower shell 8 are of a hollow structure, the rotating mechanism 17 is vertically arranged in the middle of the upper shell 7, the middle of the lower shell 8 is provided with a limiting groove 13 matched with the rotating mechanism 17, the rotating mechanism 17 comprises a rotating shaft 2 and an L-shaped connecting arm 9 arranged in the middle of the rotating shaft 2, and two side portions of the extending portion 6 are provided with wiring holes 18 aligned with the through holes 11.
