Embodiment 1

[0021] like figure 1 Shown is a consistent test electrode device, including an insulating test piece, a high-voltage test electrode 3 and a low-voltage test electrode 4, the insulating test piece includes a base 1 made of insulating material to be tested, and a first accommodation groove 5 is provided on one side of the base , the other side of the substrate opposite to the first accommodation groove is provided with a second accommodation groove 6, the first accommodation groove 5 coincides to accommodate the high-voltage test electrode 3, and the second accommodation groove 6 coincides to accommodate the low-voltage test electrode 4; the first accommodation groove and There is an insulating part 2 between the grooves integrally formed with the base body between the second receiving grooves.

[0022] By completely wrapping the test electrode, problems such as partial discharge caused by the structure of the test device body in the existing GB1408 "Electric Strength Test Metho...

Embodiment 2

[0032] The difference from Embodiment 1 is that the test electrode device also includes a casing 9 for placing an insulating test piece, and an insulating gas 10 is filled in the casing. The high-voltage electrode is connected to the conductive and supporting component 7 , and the low-voltage electrode is connected to the conductive component 8 .

Abstract

The invention relates to an insulating test piece and a test electrode device using the same. The insulating test piece comprises a base body (1) made of a insulating material to be tested, a first holding groove (5) for matching and holding a high-voltage test electrode (3) is arranged on one side of the base body, a second holding groove (6) for matching and holding a low-voltage test electrode (4) is arranged on the other side, opposite to the first holding groove, of the base body, and an inter-groove insulating part (2) integrated with the base body is arranged between the first holding groove and the second holding groove. Compared with a traditional insulating material electric intensity test method, the local discharge of the material surface is reduced, the test result is more accurate, the test environment of the invention is consistent with the actual operation environment of the electric equipment, and the test result has more practical guiding significance.

Description

technical field [0001] The invention relates to an insulating test piece and a test electrode device using the insulating test piece. Background technique [0002] The insulation performance of high-voltage electrical equipment directly determines whether the power system can operate reliably. In order to effectively ensure the excellent insulation performance of high-voltage electrical products, the power frequency (48Hz~62Hz) short-term electric strength and 1.2 / 50μs pulse voltage of the insulating material must be checked. Electrical strength under stress is tested. [0003] The method of measuring the electric strength of insulating materials is mainly based on GB1408 "Test Method for Electric Strength of Insulating Materials". In order to prevent flashover, the electric strength test is carried out in transformer oil. The thickness of the pouring insulating test strip is required to be 1.0±0.1mm, and the measurement is carried out by electrodes with unequal diameters. ...
