Abstract
The invention discloses a transformer high-voltage side direct-current resistance test auxiliary device, relates to a transformer high-voltage side resistance test device, and aims to solve the problems that the personal safety of personnel cannot be guaranteed and the test efficiency is poor in the existing test method. An insulating sleeve is of a cylindrical structure with openings in the two ends. The plurality of contact type spring pieces are fixed on the inner wall of the insulating sleeve in a circumferential arrangement mode; the cross arm is fixed on the top end opening side of the insulating sleeve through a screw, and the bottom end opening side of the insulating sleeve is used for being inserted on a high-voltage side bushingbinding post; the horizontal plug-in is fixed on the cross arm; one end of the wiring rod penetrates through the side wall of the insulating sleeve and is fixed on the contact type spring piece, and the other end of the wiring rod is connected with a resistance testing device; one end of the handheld insulating rod is connected to the outer side of the bottom of the U-shaped plug through a connecting piece; and the U-shaped plug is matched with the horizontal plug-in for use. The beneficial effects are that on the premise of ensuring personal safety, the test efficiency and the test precision and accuracy are substantially improved.
Description
technical field [0001] The invention relates to a transformer high-voltage side resistance testing device. Background technique [0002] At present, the existing DC resistance test on the high-voltage side of the main transformer of 110kV and above mainly relies on the test personnel to climb up the high-voltage side bushing of the main transformer to conduct the test connection, so as to carry out the DC resistance test. This method has the following disadvantages: First, the current Some test methods require the test personnel to climb the main transformer, and there is a risk of falling from high altitudes; second, the existing test methods take a long time to connect, which affects the test efficiency. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the problems that the personal safety of personnel cannot be guaranteed and the testing efficiency is poor in the existing testing method, and proposes an auxiliary device for testing the ...
