Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
(embodiment 1)
See Fig. 1, the 10kV vacuum circuit breaker loop resistance testing auxiliary device of the present embodiment, forms primarily of web joint 1 and connecting cylinder 2.
The material of web joint 1 is conducting metal.In the present embodiment, the preferred stainless steel of material of web joint 1.Web joint 1 is rectangular plate body part.
The material of connecting cylinder 2 is conducting metal.In the present embodiment, the preferred stainless steel of material of connecting cylinder 2.Connecting cylinder 2 is integrally made up of body 21 and Plug Division 22.Body 21 is the right cylinder of hollow, and Plug Division 22 is the Rotary-table of hollow; Plug Division 22 is connected with the front end face one of body 21 by end face thereafter; The external diameter of the front end face of Plug Division 22 is less than the external diameter of rear end face; The external diameter of the rear end face of Plug Division 22 is identical with the external diameter of body 21, and body 21 and the hollow part of Plug Division 22 are the identical circular port in aperture and axle center is identical.The Plug Division 22 of connecting cylinder 2 is designed to truncated cone-shaped, the switch movable contact grafting of convenience and 10kV vacuum circuit breaker when object is use.
