Abstract
An arrangement structure of power plant 750 kV main transformers and outgoing lines thereof in an air cooling island is characterized in that an enclosed bus, main transformer modules and lightening arresters on the high-voltage sides of the main transformers are arranged between air cooling island supporting pillars near a side of a steam engine room. The 750 kV main transformer outgoing lines adopt tubular buses which are suspended on a steel structure crossbeam by utilizing V-shaped insulator chains. The steel structure crossbeam is fixed between the air cooling island supporting pillars. According to the arrangement structure, the arrangement of the 750 kV main transformer and the outgoing lines thereof in an air cooling island is realized; project occupation of land and investment in relative electric equipment such as the enclosed bus can be greatly reduced; building costs of projects can be substantially reduced; and at the same time, electric energy loss can be effectively reduced.
Description
Technical field
the utility model is applicable to that the connecting system electric pressure is that 750kV, air cooling platform adopt the air cooling thermal power generation unit of huge pillar apart from scheme, is specifically related to a kind of main transformer and outlet thereof the arrangement under the air cooling island.
Background technology
large-scale air cooling generator group is because before the air cooling island was arranged in steam turbine building, on high-tension side outlet of unit main transformer and main transformer and conventional clammy unit were very different.The scheme of arranging under the air cooling island is generally adopted in the main transformer of present domestic 500kV electric pressure and the outlet of main transformer high-pressure side, but this arrangement does not also design precedent on 750 electric pressures.Realization 750kV main transformer and outlet thereof are arranged under the air cooling island, can greatly reduce related electric investment of devices such as project occupation of land, and enclosed busbar, and when significantly reducing project cost, electric energy loss also effectively reduces.
The utility model content
The purpose of
the utility model provides the scheme that a kind of power plant 750kV main transformer and outlet thereof are arranged under the air cooling island, reduce project occupation of land, reduces investment and electric energy loss.
are for realizing above-mentioned purpose; The utility model provides a kind of power plant 750kV main transformer and the arrangement of outlet under the air cooling island thereof; It is characterized in that: enclosed busbar, main transformer group and main transformer high-pressure side lightning arrester are arranged under the air cooling island between the air cooling island support post near the steam turbine building side; Tube type bus is adopted in the outlet of 750kV main transformer, utilizes the V-type insulator string to hang on the steel construction crossbeam, and the steel construction crossbeam is fixed between the support post of air cooling island.
A phase outlet is passed through for guaranteeing safe clear distance in
between per two support posts.
the utility model realization 750kV main transformer and outlet thereof are arranged under the air cooling island; Can greatly reduce project occupation of land; And related electric investment of devices such as enclosed busbar, when significantly reducing project cost, electric energy loss also effectively reduces.
