Description

Power station at dam toe's outlet method for arranging
Technical field
The present invention relates to construction of hydropower stations fields, more particularly, to power station at dam toe's outlet method for arranging.
Background technique
Currently, the construction of hydropower stations mostly uses formula arrangement behind the dam of power station, according to hydraulic and hydroelectric engineering dam site region Geology, the type of landform and dam determines.The distance between factory building object and dam are long or short, factory building object with Between dam it is more spacious under conditions of, there is no difficulties for power station outlet Ground arrangement.When between factory building object and dam When being closer, power station outlet place can not be arranged, currently available technology scheme is usually in addition to select near power station The facilities such as framework necessary to conducting wire are sent out in outlet Ground arrangement electrical equipment and power station;Electric energy, which is sent out, passes through cable by power station Conducting wire is to the field of line out;Have the disadvantage that while the field of line is in addition selected near power station
1, due to factory building object nearby have lay out the field of line condition it is often poor, excavation, embankment and traffic route It is big to build investment;
2, power station is by cable conductor to the field of line out, and cable purchase cost is high, and cable duct excavation project amount is big, and cable is sent Electricity operation reliability does not have aerial condutor high reliablity;When cable breaks down, determines that abort situation is not intuitive, often to borrow Failure instrument equipment is helped to debug, and aerial condutor is compared in cable debugging, repair time is long;
3, the construction of hydropower stations goes out the field of line and will face expropriation of land again, excavate hillside, smooth location, leads to the broken of environmental ecology It is bad.
4, power station is built up put into operation after, operator on duty make an inspection tour maintenance span including outlet field device, make an inspection tour maintenance people Member needs descending of climbing on hill path, it is big to make an inspection tour range, or even also to configure special-purpose vehicle, makes an inspection tour maintenance personnel's labor intensity It is high.
Summary of the invention
It is an object of that present invention to provide a kind of power station at dam toe's outlet method for arranging, make full use of the major and minor factory in power station Space between room and dam is completed power station electric energy and is sent out.
To achieve the above object, the present invention takes following technical proposals:
