Problems solved by technology

[0004] In order to solve the problem that the probe slips easily when the pillar insulator is used for the inspection of the porcelain bushing in the prior art, the probe cannot reliably contact the cylinder of the porcelain bushing, and the test results are not credible due to the high installation position of the high-voltage porcelain bushing, which is difficult for technicians to confirm. Problem,

Abstract

The invention provides a three-support point porcelain bushing vibration detector. The three-support point porcelain bushing vibration detector comprises an insulating rod and an auxiliary support apparatus. The upper end of the insulating rod is provided with a portable porcelain post insulator charged flaw detector. The lower end of the auxiliary support apparatus is connected to the portable porcelain post insulator charged flaw detector or the insulating rod. When a porcelain bushing is detected by the portable porcelain post insulator charged flaw detector, the upper end of the auxiliary support apparatus and two probes of the portable porcelain post insulator charged flaw detector can simultaneously contact with the cylindrical surface of the porcelain bushing. A test result shows that the three-support point porcelain bushing vibration detector is trusted. The three-support point porcelain bushing vibration detector can be operated simply, has high detection efficiency and is convenient for detection of various types of porcelain bushings.

Description

technical field [0001] The invention relates to a vibration detector for a porcelain sleeve, in particular to a three-support vibration detector for a porcelain sleeve that can stably detect a porcelain sleeve. Background technique [0002] High-voltage porcelain bushings are mainly used for insulating support of lead wires of power transmission and transformation equipment or as insulating containers. Porcelain sleeves are electric porcelain products fired at high temperature. If the formula is improper during production, the raw materials are not mixed uniformly during the process, or the furnace temperature is not well controlled during high-temperature sintering, internal defects of the porcelain parts are likely to be formed. Porcelain sleeves are brittle materials and have no fixed ability to change shape. Moreover, it is combined with cement adhesive and metal accessories. Due to the different linear expansion coefficients and thermal conductivity coefficients of cem...
