Abstract

The invention discloses an experimental device for testing compatibility of a transformer, in the experimental device, a tank body is made of a stainless steel material, the tank body comprises a bottom and a side wall extending from the bottom, the side wall is enclosed to form a top opening, and the tank body accommodates a transformer solid material and an insulating liquid; the sealing flange is arranged at the top end opening, and a plurality of fixing holes are uniformly distributed in the sealing flange; the sealing gasket comprises a metal graphite wound gasket; the sealing cover is arranged at the top end opening, the sealing cover and the sealing flange are fixed through the fixing hole, and the sealing gasket is connected between the sealing cover and the sealing flange in a sealing mode; the gas inlet valve is arranged on the sealing cover so as to input gas into the tank main body; the gas outlet valve is arranged on the sealing cover to output gas in the tank body.

Description

technical field [0001] The invention belongs to the technical field of transformer compatibility testing, in particular to an experimental device for transformer compatibility testing. Background technique [0002] Compatibility refers to the ability of materials to be used together without any impairment in all respects. In the power insulation system, when the materials with good compatibility are used together, serious harmful physical and chemical reactions will not occur, which can ensure the effectiveness of the insulation system. During the long-term operation of the transformer, solid materials such as the enameled wire inside the transformer, the inner surface paint of the transformer, the surface paint of the silicon steel sheet, the sealing ring and gasket, and paper will come into contact with the filled insulating liquid and may react. If the insulating liquid is incompatible with the solid material, the operating life of the transformer will be affected, and e...
