preparation example Construction

[0030] In the second aspect, the preparation method of the above-mentioned insulating base, the specific steps are:

[0031] Bind several insulating plates to form a square structure to obtain an insulating support seat;

[0032] Fixedly connect one end of the insulating sticky hook to the insulating support base;

[0033] Place the insulating ruler laterally on the insulating sticky hooks.

[0034] The stability of a single insulating board is poor, so according to the test needs, several insulating boards are used to compound and prepare the insulating support seat. Two insulating support bases are used to support the sample to be tested. Firstly, the insulating board can be saved; secondly, it can prevent the current from passing through the insulating support base to avoid breakdown; thirdly, the distance between electrodes can be easily adjusted according to the test requirements.

[0035] In some embodiments of the present invention, several insulating boards are washe...

Embodiment 1

[0043] The preparation method of the insulating base, the specific steps are:

[0044] S1, choose an insulating board with the same length 8cm and width 8cm, and the thickness range is 3-5mm;

[0045] S2, the insulation boards are first cleaned with tap water one by one, then deeply cleaned with absolute ethanol, finally rinsed with distilled water, and then dried in an oven;

[0046] S3, bind the clean insulating boards in S2 one by one with insulating tape, then align the three insulating boards with insulating tape and fix them into an insulating support base, prepare another insulating support base in the same way, and can be perpendicular to Stand the operating platform;

[0047] S4, stick the insulating hooks to the side of the insulating bracket respectively, the height of the sticking positions is the same, press until it is firm;

[0048] S5, select an insulating ruler with a maximum scale of 10-30cm;

[0049] S6, horizontally place the selected insulation scale on...

Abstract

The invention relates to an insulating base for testing flashover characteristics of a coating as well as a preparation method and application of the insulating base. The insulating base comprises twoinsulation supporting seats, an insulation ruler and two fixing devices, each insulation supporting seat is of a square structure, the corresponding positions of the two insulation supporting seats are each provided with one fixing device, the two fixing devices are located on the same horizontal line, the two ends of the insulation ruler are movably connected with the fixing devices, and each insulation supporting seat is formed by compositing a plurality of insulation plates. And the insulation performance is good, the test is flexible and convenient, and the distance between the two insulation supporting seats can be flexibly adjusted according to the measurement of the insulation ruler.

Description

technical field [0001] The invention belongs to the technical field of electrical insulation, and in particular relates to an insulating base for testing the flashover characteristics of a coating, a preparation method and an application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] In the field of electrical insulation, as the power industry has higher and higher requirements for external insulating materials, there are more and more testing experiments for electrical insulation performance. The insulating base is mainly used to support the tested sample in the high-voltage test environment, insulate it from the test platform, and avoid conduction. Flashover refers t...
