【Abstract】:Along with the our country developments business of booming development, the power supply realm flowed out into many new techniques, new equipments;Nation and also the cowgirl establishes a series of technique policy with design the norm.The transformer substation technique is through the development of more than ten years, inclining to already and gradually the automation, arithmetic figure turns, the intelligence turns.This design develops to the electric power industry of the our country first, the concept of the electric power system waited to do with the type of the transformer substation a first step generalizes.Then pass to investigate on the spot, the analysis of the data, proceed the burthen calculation of the transformer substation with have no the coefficient the in expiation of calculation the etc..Make use of again the result to count to the main transformer set to proceed the choice with capacity to settle with main knot line project really.Among them connect to the lord the linear choice did than for expatiation, also pass the sketch check against the proceeding makes sure.Then pass to the short-circuit calculation, choice high pressure switch equipments.At the same time in consideration of When the system occurrence break down, must have the homologous protection device, therefore too to two times knot line with after and did the synopsis the elucidation.Proceeded come from exterior thunder and lightning conduct electricity press, very much to defend the thunder protect with the design that connect a ground of devices.At complete the theories explanatory at the same time, increased a few diagrams paper, in order to in comprehend with start construction more easily.
