| titleOfInvention | Method and heater for uniformly curing a resin impregnated electrical bushing |
| abstract | Method and heater for uniformly curing a resin impregnated electrical bushing. The method comprises precuring a resin impregnated wound structure of the bushing by heating simultaneously equal sections of the wound structure from bottom to top of the wound structure internally through the hollow conductor at progressively reducing temperatures from bottom to top sections of the wound structure starting with a temperature of 90 - 110° C for the bottom section and progressively reducing the temperature of precuring for the intermediate sections up to the top section by a temperature gradient of 4-6°C. The wound structure is cured by heating the equal sections of the wound structure internally through the hollow conductor at progressively reducing temperatures from bottom to top sections of the wound structure starting with a temperature of 1 10-130°C for the bottom section and progressively reducing the temperature of curing for the intermediate sections upto the top section by a temperature gradient of 4-6°C. The heater (1) comprises a vertically disposed thermal conductor material hollow cylindrical body (2) having a plurality of heater elements (3) of different wattages wound over the cylindrical body one above another corresponding to equal sections of the wound structure from bottom to top of the wound structure. The wattages of the heater elements reduce progressively from bottom heater element to the top heater element to generate temperatures ranging from higher temperature to lower temperatures from the bottom heater element to the top heater element through the intermediate heater elements upto the top heater element with a temperature gradient. Each of the heater elements is associated with a temperature sensor (4) located on the cylindrical body and control panel (5) connected to the heater elements and temperature sensors. |
