Abstract

The invention relates to a portable test wiring bench for a high-voltage test. The structure of the bench is characterized in that an insulating board is arranged in a box body; wiring insertion holes are formed in the insulating board; and high-voltage wire insertion holes are formed in side of the box body. Binding posts I and binding posts II are respectively arranged in the high-voltage wire insertion holes and the wiring insertion holes; insulators sleeve the outer surfaces of the binding posts I and the binding posts II; and bus bars are connected between the binding posts I and the binding posts II. According to the invention, all devices for items of the transformer commissioning test and the routine test are integrated to the test bench and thus integrated switching can be completed by one set of test wires so as to complete corresponding test items.

Description

technical field [0001] The invention relates to a test stand, in particular to a portable test connection stand for high-voltage tests, which is suitable for on-site transfer tests and routine tests of 220kV transformers, and belongs to the field of electric power applications. Background technique [0002] There are many test items in the field test of 220kV transformers. Usually, many different instruments and equipment are used for testing. During the test, the instruments and equipment and the test wiring must be replaced many times. The bushings on the high-voltage side and medium-voltage side of the 220kV transformer are very high. For example, the test personnel have to climb up and down the transformer many times to operate. This working mode is not only labor-intensive, the site is chaotic, and it is prone to safety accidents. Contents of the invention [0003] Aiming at the problems in the above-mentioned prior art, the present invention provides a portable test ...
