Experimental research device for research on electrical performance of mixed gas for high-voltage electrical equipment

Abstract

The invention relates to the field of high-voltage power transmission technology, and particularly relates to a test research device used for electrical performance research on mixed gas of high-voltage electrical equipment. The device comprises a lead terminal gas room connected with a high-voltage casing; the lead terminal gas room is connected with a horizontally-arranged barrel body; the barrel body is isolated by a basin-type insulator into a first test gas room and a second gas room; the first test gas room is adjacent to the lead terminal gas room; the barrel body of the first test gas room is provided with a mounting port; a flange used for mounting a test-used post insulator and a cover plate used for covering the mounting port are arranged at the mounting port; two guide rods coaxial in the horizontal direction and arranged at intervals are arranged in the second test gas room; the guide rod is provided with opposite end parts for removing an assembly contact or an arc contact or a shielding cover; and at least one of the two guide rods is in transmission connection with a driving mechanism used for driving the corresponding guide rod to move along the axial direction of itself so as to adjust the gap between the opposite end parts of the two guide rods. By adopting the device of the invention, dynamic and static tests can be carried out.

Description

technical field [0001] The invention relates to the technical field of high-voltage power transmission, in particular to an experimental research device for researching the electrical properties of mixed gas of high-voltage electrical equipment. Background technique [0002] The Chinese patent application number 200810112990.2 discloses a test and research device for DC gas-insulated metal-enclosed transmission line (GIL). And the high-voltage bushing, it also includes three air chambers distributed along the horizontal direction, the three air chambers are separated by two basin insulators, respectively the first, second, and third air chambers, and the first air chamber is set in the high-voltage bushing The lower end of the first air chamber is the lead end air chamber connected with the high-voltage bushing, the third air chamber is the test air chamber, and the third air chamber is equipped with a guide rod and a post insulator arranged at the lower part of the guide ro...

AI Technical Summary

Problems solved by technology

Since there is only one guide rod in the test gas chamber in this device, and the guide rod is fixed, this device can only be used for static tests in a single gas chamber, and cannot be used for research on the breakdown characteristics of mixed gas insulation gaps, mixed gas arcs, etc. Research (drawing arc test)
