Problems solved by technology

At present, the test method for the porosity of insulators is mainly the magenta solution test method. The test method is mainly to directly put the insulator into a container with alcohol fuchsin solution and a pressurized function. The penetration of the red solution in the insulator, this test method has the advantages of simple process and easy operation, but it often has the phenomenon of continuous pressure instability and incomplete penetration of the alcohol fuchsin solution, resulting in inaccurate results of porosity detection

Embodiment Construction

[0018] In this embodiment, an insulator porosity tester has a test cavity 1, the upper end of the test cavity 1 is an opening, and an openable locking device 2 is installed on the opening. 1 The support frame 3 on the chamber wall, the support frame 3 is located above the opening of the test chamber 1 and a screw 4 is installed, the upper end of the screw 4 is equipped with a rotating hand wheel 5, and the rotating hand wheel 5 is provided with a handle 6, The lower end of the screw mandrel 4 is equipped with an end cover 7 that is engaged with the opening of the test cavity 1. When an insulator or alcohol-magenta solution needs to be placed in the test cavity 1, the screw mandrel 4 is rotated to make the end cover 7 open upwards.

[0019] In this embodiment, the bottom of the test chamber 1 is fixedly installed with a base 8 through threads, and a test bench 9 for placing insulators is installed on the base 8. On the chamber wall of the test chamber 1, an alcohol fuchsin solut...

Abstract

The invention relates to the field of insulator testing equipment, and specifically relates to a porosity testing instrument for an insulator. The porosity testing instrument for the insulator comprises a testing chamber, wherein an opening is formed in the upper end of the testing chamber; a locking device which can be opened is mounted on the opening; a base is mounted at the bottom part of thetesting chamber in a sealing manner; an injecting device for injecting testing liquid is connected to the wall of the testing chamber through a testing liquid pipeline; and the injecting device is connected with a hydraulic station control cabinet. With the adoption of the porosity testing instrument for the insulator, a stable pressure increase environment can be supplied for a long time, so thatthe accuracy of the insulator porosity test can be greatly improved; and the instrument has a good application prospect.

Description

technical field [0001] The invention relates to the field of insulator testing equipment, in particular to an insulator porosity tester. Background technique [0002] Insulator is a common power cable accessory, mainly used in high voltage transmission technology equipment. Porosity is an important index in insulator testing, which directly affects its own performance. At present, the test method for the porosity of insulators is mainly the magenta solution test method. The test method is mainly to directly put the insulator into a container with alcohol fuchsin solution and a pressurized function. The penetration of the red solution in the insulator, this test method has the advantages of simple process and easy operation, but it often has the phenomenon of continuous pressure instability and incomplete penetration of the alcohol fuchsin solution, resulting in inaccurate results of porosity detection . Contents of the invention [0003] In order to solve the problems e...
