Abstract

The invention discloses a single-pipe gas relay detecting bench, a centering clamping mechanism and a detection method of the single-pipe gas relay detecting bench, belonging to the technical field of transformer gas relay detection, to solve the problem that an existing gas relay is low in clamping efficiency and a multi-caliber gas relay cannot be detected. The invention provides the centering clamping mechanism for detecting the gas relay, which comprises a fixed end and a moving end, wherein the fixed end is provided with a fixed end jack, the moving end forms a first-class secondary seal guide plate, and the mechanism can detect the gas relay with different calibers. The invention also provides the single-pipe gas relay detecting bench which comprises a rack and an oil tank which are arranged on an enclosure, and a heavy gas velocity test circuit connected between the rack and the oil tank, wherein the rack is provided with the centering clamping mechanism. The invention also provides a method for detecting the heavy gas velocity value, the light gas velocity value and the pressurization sealing value of the gas relay with different calibers by using the single-pipe gas relay detection bench.

Description

technical field

[0001] The invention belongs to the technical field of transformer gas relay detection, and specifically relates to a sealed guide plate with the same nominal diameter corresponding to the gas relay to be tested by simulating the action mechanism of the gas relay when the internal fault of the transformer is used, using the industrial computer measurement and control technology, and transforming through a single detection pipeline , change the oil cut-off area of ​​the oil flow to be consistent with the nominal diameter cross-sectional area of ​​the gas relay to be tested, so as to meet the gas relay test bench and its clamping device for the detection of heavy gas flow rate values ​​of domestic and foreign gas relays of different calibers, different manufacturers, and different models. Background technique

[0002] When the gas relay testing station clamps the gas relay, due to the different manufacturers, models and calibers of the gas relay under test, the ...
