specific Embodiment 1

[0068] Such as figure 1 As shown, the insulation pull rod electric test system provided in this embodiment includes a pressure test bushing 9 for providing a test voltage and an insulation pull rod electric test device connected to the pressure test bushing 9. The insulation pull rod electric test device includes a test cylinder 1. The test cylinder 1 is provided with a pressure test bushing interface 21 and a pressure test conductor joint 22, and the pressure test conductor joint 22 is connected with an insulating rod installation assembly, which includes a first mounting seat 31 and a second mounting seat 35. The first and second mounting bases are equipped with a plurality of insulating pull rod fixing structures correspondingly. When the insulating pull rod 8 is electrically tested, the insulating pull rod 8 to be tested is fixed between the first and second mounting bases. The insulating pull rods 8 are connected side by side in parallel in the same pressure test circuit,...

specific Embodiment 2

[0080] The main difference between it and Embodiment 1 is that in Embodiment 1, three insulating pull rod fixing structures are respectively provided on the first and second mounting bases. In this embodiment, six insulating pull rod fixing structures are respectively provided on the first and second mounting bases. In other embodiments, the number of insulating pull rod fixing structures can be determined according to actual needs, but it must be ensured that the number of insulating pull rods on the first and second mounts is equal, and the number of insulating pull rods on each mount is not less than two .

specific Embodiment 3

[0082] The main difference between it and Embodiment 1 is that in Embodiment 1, the fixing structure of the insulating pull rod on the first mounting base is a positioning structure, and the fixing structure of the insulating pulling rod on the second mounting base is a screw connection structure. In this embodiment, the insulating pull rod fixing structure on the second mounting base is a positioning structure, and the insulating pulling rod fixing structure on the first mounting base is a screw connection structure.

Abstract

The invention relates to an insulation pull rod electric test device, an electric test system and an electric test method.The insulation pull rod electric test system comprises a pressure test sleeve and an insulation pull rod electric test device, the insulation pull rod electric test device comprises a test cylinder, and the test cylinder is provided with a pressure test sleeve interface and a pressure test conductor connector; the voltage test conductor joint is connected with an insulating pull rod mounting assembly, the insulating pull rod mounting assembly comprises a first mounting seat and a second mounting seat, the first mounting seat and the second mounting seat are respectively provided with more than two insulating pull rod fixing structures, and the insulating pull rod fixing structure on one of the first mounting seat and the second mounting seat is electrically connected with the voltage test conductor joint. According to the insulation pull rod electric test method, a plurality of insulation pull rods are connected in the same voltage test loop in parallel through the insulation pull rod electric test device, electric tests can be carried out on the plurality of insulation pull rods at the same time, and the test efficiency of the insulation pull rods is greatly improved.

Description

technical field [0001] The invention relates to the field of electrical performance testing devices, in particular to an insulating rod electrical testing device, an electrical testing system and an electrical testing method. Background technique [0002] Insulating tie rods are important components in high voltage circuit breakers. When leaving the factory, it is usually necessary to conduct an electrical test on the insulating rod on a special detection device, among which the rated power frequency withstand voltage, rated lightning impulse withstand voltage, rated operating impulse withstand voltage, partial discharge, etc. are all tested by the insulating rod. Required items. [0003] At present, the test tooling for insulating pull rods on the market can only test a single insulating pull rod each time. The tooling includes the main body of the air chamber. The axial end of the main body of the air chamber is connected with a low-pressure sealing plug body. The low-pr...
