Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 , 2 As shown, the present invention includes an upper disc 1, a lower disc 6, a tray 7 and the like.

[0015] A connecting piece 3 and a runner 4 are arranged between the upper disc 1 and the lower disc 6 . The connecting piece 3 is a bolt and nut structure, which is used to connect and fix the upper disc 1 and the lower disc 6 as a whole. Described runner 4 is universal wheel, can assist upper disk 1, lower disk 6 to rotate on pallet 7; The upper and lower discs 6 have larger holes, which are convenient for the runner 4 to rotate.

[0016] A rotating part connecting the upper disc 1 and the lower disc 6 is set at the middle position of the tray 7, so that the upper disc 1 and the lower disc 6 can be rotated on the tray 7. The rotating part 5 is a bearing.

[0017] On the lower disc 6, some snap rings 2 that can be inserted into the lightn...

Abstract

The invention discloses a tool specially used for a zinc oxide arrester test, aiming at solving the problems of the existing test device is overlong in time consumption and lower in working efficiency; the tool is characterized by comprising an upper disc, a lower disc and a tray, wherein a connecting part and a rotary wheel are arranged between the upper disc and the lower disc; the bottom surface of the rotary wheel is arranged on the tray; a rotating part used for connecting the upper disc and the lower disc is arranged in the middle of the tray; the lower disc is provided with a plurality of clamp springs which can be inserted into an arrester; and a plurality of holes are reserved on the upper disc at the positions corresponding to the clamp springs. The tool shortens the test time, improves the ground connection safety factor and reduces the test personnel.

Description

technical field [0001] The present invention relates to a test tool, more specifically to a test tool for lightning arresters. Background technique [0002] Every spring, with the development of lightning protection work, a large number of arresters need to do preventive tests. The previous lightning arrester test methods are backward, random, take too long, work efficiency is low, and the safety factor is small. In the case of few personnel, tight time, heavy tasks and heavy workload, it is easy to make the test personnel fatigued. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a special tool for zinc oxide arrester testing, improve the test efficiency of zinc oxide arrester, be suitable for the test of zinc oxide arrester of various shapes, shorten the test time, reduce labor intensity and guarantee The safety factor of the test. [0004] The present invention is characterized in that...
