Transformer high-voltage outgoing line integration system

Abstract

The invention relates to a transformer high-voltage outlet-wire integration system.A high-voltage outlet-wire terminal is arranged on a transformer.The transformer high-voltage outlet-wire integration system comprises a closed sleeve, an arrester and a high-voltage sleeve pipe.The arrester, the high-voltage sleeve pipe and a high-voltage side outlet-wire terminal are located in the closed sleeve, the arrester and the high-voltage sleeve pipe are electrically connected with the high-voltage outlet-wire terminal respectively, and the closed sleeve is filled with insulating gas.The arrester, the high-voltage sleeve pipe and the high-voltage side outlet-wire terminal are arranged in the closed sleeve, a connecting mode with aerial jumper wires is not adopted, the closed sleeve is filled with the insulating gas, the high-voltage outlet-wire terminal can not be in contact with external media, pollution flashover of the high-voltage outlet-wire terminal is avoided, and the operation safety of a power plant is guaranteed.When the power plant is arranged and designed, intervals between other devices such as a natural ventilation cooling tower and a mechanical draft cooling tower and an outdoor high-voltage distribution device do not need to be considered, and the occupied space of power plant arrangement is reduced.

Description

technical field [0001] The invention relates to the technical field of power plant layout, in particular to a transformer high-voltage outgoing line integration system. Background technique [0002] In the electrical system of the power plant, considering the convenience of transformer maintenance and repair, and without restrictions, the high-voltage outgoing line of the 220kV main transformer mainly adopts the outgoing line connected by overhead line. Since the overhead terminals of the transformer are exposed to the air, in order to prevent the pollution and flashover of the overhead terminals of the transformer during the layout design of the power plant, the distance between other equipment such as natural ventilation cooling towers, mechanical ventilation cooling towers and outdoor high-voltage power distribution devices There are requirements for both, and the minimum spacing is generally required to be 40m, so that the area occupied by the layout of the power plant i...

Problems solved by technology

Since the overhead terminals of the transformer are exposed to the air, in order to prevent the pollution and flashover of the overhead terminals of the transformer during the layout design of the power plant, the distance between other equipment such as natural ventilation cooling towers, mechanical ventilation cooling towers and outdoor high-voltage power distribution devices There are requirements, generally the minimum spacing is required to be 40m, so that the area occupied by the layout of the power plant is large

And in some projects, due to the limited layout space, the distance between other equipment such as natural ventilation cooling towers, mechanical ventilation cooling towers and outdoor high-voltage power distribution devices cannot meet the minimum distance requirements, so it is impossible to prevent the overhead terminals of transformers from collapsing. Outlet pollution flashover problem affects the operation safety of the power plant
