A test device for acid resistance of composite insulator mandrel

Abstract

A composite insulator mandrel acid resistance test device, comprising a cylindrical test tube arranged horizontally, a tapered liquid filling hole with an internal thread is opened in the middle of the upper end of the test tube wall, and a wedge-shaped liquid filling hole is matched in the liquid filling hole The liquid filling hole soft plug, and a wedge-shaped liquid filling hole locking plug with an external thread is arranged on the upper end of the liquid filling hole soft plug; a tapered installation through hole with an internal thread is respectively provided at the center of the end surface of the test tube. , a wedge-shaped sealing plug is respectively arranged in the installation through hole, and a wedge-shaped locking plug with external thread is also arranged on the outer end of the sealing plug, and a center of the sealing plug and the locking plug is opened for insertion of a composite insulator mandrel. Through holes for active mates. The present invention has the advantages of: effectively constructing an experimental environment with good airtightness, avoiding the overflow of the acidic experimental liquid, and making the experimental results more accurate; at the same time, it also makes the experimental environment safer and reduces the need for experimental operators to be in the experimental process. security risks.

Description

technical field [0001] The invention relates to an experimental device, in particular to an acid-resistant experimental device for a composite insulator mandrel. Background technique [0002] The insulator is an important part in the power system. In order to improve the comprehensive performance of the insulator, it is often necessary to carry out experimental tests on its tensile strength, acid and alkali resistance and other aspects. The insulator mandrel is a core component of the insulator, and its comprehensive performance in all aspects also needs to be tested in a series of experiments. [0003] The traditional test device for acid resistance of composite insulator mandrel is an experiment cylinder with a through hole of the same size as the diameter of the composite insulator mandrel opposite to each other along the diameter direction. The traditional experimental device has poor airtightness. During the experiment, the acidic experimental liquid will overflow from...

AI Technical Summary

Problems solved by technology

The traditional experimental device has poor airtightness. During the experiment, the acidic experimental liquid may overflow from the gap of the through hole, which cannot meet the requirements for airtightness during the experiment, and directly affects the accuracy of the entire experiment. Acidic experimental liquid will also bring unnecessary safety hazards to the operator of the experiment
