Description

Technical Field

[0001] The utility model belongs to the field of transformer bushing manufacturing, in particular to a transformer bushing manufacturing positioning device. Background Art

[0002] Currently, transformer bushings are the primary insulation device outside transformer boxes. The transformer winding lead wires must pass through the insulating bushings, which insulate the lead wires from each other and from the transformer casing, while also securing them. Depending on the voltage level, insulating bushings come in various forms: pure porcelain bushings, oil-filled bushings, and capacitor bushings. Pure porcelain bushings are primarily used in transformers of 10kV and below. They consist of a conductive copper rod inserted through the porcelain bushing, which is insulated with air. Oil-filled bushings are primarily used in transformers of 35kV. They consist of an oil-filled, conductive copper rod wrapped in insulating paper. Capacitor bushings, used in high-voltage transformers above 100kV, consist of a main insulating capacitor core, upper and lower porcelain components for external insulation, a connecting sleeve, an oil pillow, a spring assembly, a base, a voltage-equalizing ball, measuring terminals, wiring terminals, rubber washers, and insulating oil.
