【正文】 dissimilar, concrete choice method quite same not less than, but all has the unanimous request to them, the electrical equipment must be able the reliable work, must carry on the choice according to the regular service condition, and according to shortcircuits the condition to verify the thermally stable and to move stably. The power distribution equipment is according to the electrical host wiring connection way, by the switch electric appliance, the protection and the survey electric appliance, the generator and the essential supporting facility sets up the overall installment which but bees. By this design looked 110KV suitably uses outdoor form, 35KV and 10KV suitably uses in the room the form. In order to prevent with the limit thunder and lightning hazardous 范文范例參考 WORD 格式整理 nature, in the transformer substation also should use the antiradar measure and the antiradar protective device.Key

言變電站是電力系統(tǒng)中不可缺少的重要環(huán)節(jié)，對(duì)電網(wǎng)的安全和經(jīng)濟(jì)運(yùn)行起著舉足輕重的作用，如果仍然依靠原來(lái)的人工抄表、記錄、人工操作為主，將無(wú)法滿足現(xiàn)代電力系統(tǒng)管理模式的需求；同時(shí)用于變電站的監(jiān)視、控制、保護(hù)，包括故障錄波、緊急控制裝置，不能充分利用微機(jī)數(shù)據(jù)處理的大功能和速度，經(jīng)濟(jì)上也是一種資源浪費(fèi)。因此，變電站自動(dòng)化既是實(shí)現(xiàn)自動(dòng)化的重要基礎(chǔ)之一，也是滿足現(xiàn)代化供用電的實(shí)時(shí)，可靠，安全，經(jīng)濟(jì)運(yùn)行管理的需要，更是電力系統(tǒng)自動(dòng)化
