Every district builds a series of supply and distribute establishment .The substation is the middle link between power plant and customers, whose function is transforming and distributing electric power. This time designs the topic is some 110kV transformer substation electricity preliminary design,this transformer substation is a topicality important voltage dropping resistor transformer substation, it mainly holds the post of 110kV and the 10kV two voltage rank power exchange, accepts the power all to escort to the 10kV side circuit. This institute is located middle the city, the site project situation is good, is in the local area work key position to light, has 110kV, and the 10kV three voltage ranks, the 110kV side accepts the power primarily, 10kV mainly uses in using electricity as well as the idle work pensation. This time designs the transformer substation is the key position transformer substation, after all power cut, will affect the entire area by the level under the level transformer substation power supply namely this design transformer substation final scale: Uses three three windings to have carries the regulating transformer, mutually for 110kV side V going beyond a line has 110kV and the 10kV host wiring final plan uses the double mother to uses the single mother to transformer substation power distribution equipment uses improves half high power distribution equipment, 110kV and 10kV uses the circuit breaker single row arrangement, under the isolator laying aside generatrix, will cause its and another level isolator electricity distance increases, reduces the power distribution equipment the foreandaft distance. This design paper is take technical standards and so on our country present each related standard regulations as the basis, designs is a preliminary design, provides the firsthand information according to the project description, the reference pertinent data and the books, carries on the parison to each kind of plan to obtain.
