Problems solved by technology

[0003] At present, most of the existing electrical test devices for insulating materials are open-type, and what is measured is the flashover voltage along the surface of the material, and the breakdown voltage of the material body cannot be obtained.
The closed gas insulation test device is generally used to measure the electrical performance of pot insulators, GIS and other equipment, and because the entire closed gas chamber is fully connected and has a large volume, it is necessary to perform inflating and returning operations before and after each test, which consumes a lot of energy. Long time, low test efficiency

Embodiment 1

[0044] In the conventional technology, most of the electrical performance tests on insulating materials are open, but the measured results are not the breakdown voltage of the material body. In the prior art, the closed gas-insulated test device is used. Since the entire closed gas chamber is completely connected and has a large volume, although relatively accurate test results can be obtained, it is necessary to perform inflation and return operations before and after each test, which consumes a lot of energy. The longer the time, the lower the test efficiency. This embodiment provides an electrical performance test device for insulating materials that can obtain accurate test results, improve test efficiency, and reduce test costs. The device includes a detection unit 1, a transition unit 2, and a detection voltage introduction unit 3; Unit 1 includes a first tooling cylinder 11 and a detection station 12, the detection station 12 is arranged in the first tooling cylinder 11...

Embodiment 2

[0062] Embodiment 2 is an optional embodiment of embodiment 1

[0063] As an option, there are multiple observation windows 112, specifically, two observation windows 112 are provided at an angle on the outer wall of the first tooling cylinder 11, so as to facilitate observation of test phenomena from different directions. The technical effects obtained are basically the same as those in Embodiment 1, and will not be described here one by one.

Embodiment 3

[0065] On the basis of Example 1, this embodiment proposes an electrical performance test method for insulating materials, and the specific operation process is as follows:

[0066] S1: Before the experiment, the second air chamber of the test device is evacuated through the inflating nozzle of the second tooling cylinder 21, and the insulating gas of the pressure required for the test is filled;

[0067] S2: Then remove the bolts of the door panel 113 on the first tooling cylinder 11, open the door panel 113, put the test sample at the center of the upper surface of the first electrode 121 through the door hole 111 at the door panel 113, and then adjust the first electrode 121 , reduce the distance between the first electrode and the second electrode 122 until the test sample is clamped by the first electrode 121 and the second electrode 122 and the first electrode 121 cannot rotate;

[0068] S3: Cover the door panel 113 and fix the bolts, vacuumize the first tooling cylinder...
