Multifunctional high-voltage test wiring header and use method thereof

Abstract

The invention provides a multifunctional high-voltage test wiring header and a use method thereof, the structure of the multifunctional high-voltage test wiring header comprises a box body, one side surface of the box body is provided with a panel, and the panel is sequentially provided with a first short circuit area, a high-voltage side wiring area, a second short circuit area and a low-voltage side wiring area from top to bottom; a plurality of first binding posts are arranged in the high-voltage side wiring area, a plurality of second binding posts are arranged in the low-voltage side wiring area, one ends of the first binding posts and one ends of the second binding posts penetrate through the panel and extend into an inner cavity of the box body, and the other ends of the first binding posts and the other ends of the second binding posts are located outside the panel; and a plurality of protection pressing plates are arranged in the first short circuit area and the second short circuit area. According to the invention, the short circuit of any winding in the transformer in the test loop is realized by adopting the protection pressing plate, and different windings can be short-circuited by using the protection pressing plate in sequence, so that the insulation resistance and the direct-current resistance of each winding are determined; multiple groups of resistors can be tested through one wire box, and the multifunctional effect is achieved.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a multifunctional high-voltage test junction header and a method for using the same. Background technique [0002] In order to ensure the stable and safe operation of power equipment, power workers often conduct preventive tests and handover tests on power equipment. When conducting insulation resistance and DC resistance tests on transformers, no personnel should stay on the top of the transformer during the test, and personnel must keep a sufficient safe distance from the equipment under test and the test wiring. In the test, it is necessary to change the wiring mode of the winding. The test personnel climbed up and down the ladder many times to reach the top of the transformer, and performed the operation of changing the wiring of the high and low voltage windings. It brings a heavy workload and a long test time to the test personnel. [0003] In the existing auxi...
