Abstract

The invention provides complete power-frequency oil-gas partial discharge-free test transformer equipment and relates to the field of manufacturing of complete transformer equipment for testing a gas insulated switchgear (GIS) high-voltage switch and a disc insulator. The equipment comprises a transformer, a high-voltage isolation impedor, a high-accuracy voltage measuring device, a square wave measuring device, a coupling capacitor and a capacitive voltage divider. The output end of the transformer is coupled with a square wave injection device; the output end of the square wave injection device is connected with the input end of the high-voltage isolation impedor; the output end of the high-voltage isolation impedor is connected with the input end of the coupling capacitor; the output end of the coupling capacitor is connected with the capacitive voltage divider and the high-accuracy voltage measuring device; the output end of the capacitive voltage divider is provided with a measuring port; and the square wave measuring device, the high-voltage isolation impedor, the high-accuracy voltage measuring device, the coupling capacitor and the capacitive voltage divider are arranged in sealed pipelines filled with SF6 gas respectively. The device has the advantages of long rated running time, small floor area and convenient operation.

Description

technical field [0001] The invention relates to the manufacturing field of a transformer complete set for testing GIS high-voltage switches and pot insulators. Background technique [0002] The existing oil-immersed power frequency non-partial discharge test transformer complete set is relatively large in size, occupies a large area and occupies a large space, especially the test requires a shielding hall, and the shielding hall required by this device is relatively large. Larger, the cost of consumption is relatively high; in the face of my country's growing UHV power industry, the existing product structure and technical output products are larger, from the perspective of economics and electricity, Such products cannot meet the needs of UHV power utilities. [0003] Several foreign companies have produced power frequency test transformers that are fully charged with SF6. Because the transformer part adopts a gas-type structure, the running time of this device is not long. I...
