Insulator electric appliance performance test system for high-voltage electric appliance

Abstract

The invention relates to an insulator electric appliance performance test system for a high-voltage electric appliance. The system comprises a test outer tank, a shielding assembly and a test sample,wherein the test outer tank includes a tank body, a supporting pedestal, and an upper cover plate; the shielding assembly includes an out-tank grounding end shielding ring arranged on the outer side of the supporting base, a pair of in-tank high-voltage crimping shielding rings arranged in the tank body, an in-tank grounding end shielding ring and a high-voltage outer side shielding ring which isarranged on the outer side of the upper cover plate in a sleeving manner and covers the upper cover plate; and the test sample is arranged in the test cavity of the tank body. The system has the advantages that the invention provides a miniaturized and low-cost test system which is suitable for completing the partial discharge test of the insulator in a space-limited laboratory, and the system islight in weight, convenient to move and simple to operate; and the system is suitable for power equipment maintenance station insulator inspection, incoming inspection of the insulators of high-voltage equipment manufacturers and delivery inspection of small-scale insulator manufacturers, can effectively reduce the investment cost of detection equipment, is proper in cost performance, and can ensure reliable detection of the insulators.

Description

technical field [0001] The invention relates to a high-voltage switch test device, in particular to an electrical performance test system for insulating parts used in high-voltage electrical appliances. Background technique [0002] In the State Grid "Technical Specifications for General Equipment of Porcelain Column SF6 AC Circuit Breakers" (approval version), there are clear requirements for equipment manufacturers in terms of partial discharge test capabilities of insulating parts. In the supervision of high-voltage products, it is required to conduct electrical performance-power frequency and partial discharge tests on the insulating parts used in the products. At present, manufacturers generally use traditional power frequency partial discharge equipment for testing, and complete the power frequency partial discharge performance test through human cooperation. The efficiency of personnel operation and test accuracy are not ideal. [0003] At present, manufacturers gene...
