Abstract

The invention discloses a fixing structure of a plate-type potential resistor. The fixing structure includes a potential resistor positioned under an on-load switch; the potential resistor is fixed on a bottom of an oil tank; a high-voltage lower clamping member and a low-voltage lower clamping member are symmetrically arranged on two sides of the potential resistor; fixing plates are arranged on the high-voltage lower clamping member and the low-voltage lower clamping member; first wireman lamination wood members are arranged on the fixing plates; and the potential resistor are fixedly connected to the two first wireman lamination wood members. Independent installation of the plate-type potential resistor can be achieved, the height of the on-load switch is lowered, the height of a transformer oil tank is lowered, the use amount of steel plates and transformer oil is reduced, and the manufacturing cost of a transformer is greatly reduced.

Description

technical field [0001] The invention relates to a support structure of an oil-immersed transformer on-load switch plate type potential resistance, belonging to the technical field of electric equipment. Background technique [0002] For the on-load tap changer, the voltage adjustment function is realized without cutting off the load. In the mode of forward and reverse voltage regulation and coarse and fine voltage regulation, during the operation of the change-over selector of the tap changer, because the voltage regulation winding is temporarily separated from the winding, the potential of the tap winding is suspended. If the floating potential is too high, it will discharge, causing the transformer oil to decompose and generate gas, which will endanger the insulation performance of the product. To solve the above hazards, it is necessary to use the method of connecting potential resistance. The traditional potentiometer is installed at the bottom of the on-load switch and...
