Embodiment 1

[0023] Such as figure 1 versus figure 2 A disk-shaped test support for zinc oxide surge arresters is shown, comprising a base 1, on which a first vertical and upward cylindrical protrusion 2 is provided, and an insulating tube 3 is sleeved on the first protrusion 2; The metal support frame 4 includes a circular ring-shaped metal support frame 4, and the metal support frame 4 is in the shape of a hub. The center of the ring of the metal support frame 4 is provided with a vertical downward cylindrical second protrusion 5, the second protrusion 5 is inserted into the upper end of the insulating tube 3; N threaded holes 6 are uniformly distributed on the metal support frame 4, where N is a positive integer greater than or equal to 2; the metal support frame 4 is also provided with a grounding terminal 7. The base 1 is in the shape of a hub, and the first protrusion 2 is arranged at the center of the base 1. Eight threaded holes 6 are evenly distributed on the metal support frame 4...

Embodiment 2

[0026] Such as image 3 A zinc oxide arrester disc-shaped test stand is shown. On the basis of Example 1, the base 1 has a solid disc-shaped structure, and the base 1 is made of precast concrete. The length of the insulating tube 3 is greater than or equal to 0.5 m. The outer diameter of the second protrusion 5 is smaller than the inner diameter of the insulating tube 3 by 2 to 4 mm. The solid disc has a relatively large structure, which is beneficial to improve the stability of the base 1, and at the same time, the price of precast concrete is low, which is beneficial to reduce the production cost. The length of the insulating tube 3 is greater than or equal to 0.5 m, to ensure that the metal support frame 4 on the upper part of the insulating tube 3 is sufficiently high from the ground to ensure safety during the test.

Abstract

The invention discloses a disk-shape testing support for zinc oxide arresters. The disk-shape testing support comprises a base; the base is provided with a first cylindrical projection which protrudes upwardly and vertically; the first projection is sleeved with an insulating pipe; the disk-shape testing support further comprises a circular-ring-shaped metal supporting frame; the metal supporting frame is hub-shaped; the center of the circular ring of the metal supporting frame is provided with a second cylindrical projection which protrudes downwardly and vertically; the second projection is inserted into the upper end of the insulating pipe; N threaded insertion holes are distributed evenly in the circular ring of the metal supporting frame, wherein N is a positive integer greater than or equal to 2; and the metal supporting frame is further provided with a grounding terminal. With the disk-shape testing support for the zinc oxide arresters of the invention adopted, the problem of inconvenient fixation and frequent wire replacement in the direct-current leakage test of zinc oxide arresters in the prior art can be solved, and the fixation and support of a plurality of zinc oxide arresters can be facilitated.

Description

Technical field [0001] The invention relates to the field of lightning arrester auxiliary equipment, in particular to a disk-shaped test bracket for a zinc oxide arrester. Background technique [0002] Because the zinc oxide arrester needs to remove the arrester from the installation equipment during the DC leakage current test, the DC leakage current belongs to the high-voltage test. It requires a certain safe distance between the arrester pressure end and the grounding end, and the arrester itself has no base. Personnel often use temporary objects to support the arrester upright for testing, which is difficult to meet the test conditions of the arrester, and the test safety is also difficult to guarantee. The testers need to frequently change the line and fix the arrester, which wastes a lot of time. Summary of the invention [0003] The purpose of the present invention is to provide a zinc oxide arrester disk test support to solve the problems of poor fixation and frequent line...
