變(bian)(bian)電(dian)站的一次設備(bei)(bei)指直接生產(chan)、輸(shu)送、分配和(he)(he)使用電(dian)能的設備(bei)(bei)，主要包括變(bian)(bian)壓器(qi)(qi)、高壓斷路器(qi)(qi)、隔離開(kai)關、母線、避(bi)雷(lei)器(qi)(qi)、電(dian)容器(qi)(qi)、電(dian)抗(kang)器(qi)(qi)等(deng)。變(bian)(bian)電(dian)站的二次設備(bei)(bei)是指對(dui)一次設備(bei)(bei)和(he)(he)系(xi)統的運行工況(kuang)進行測量(liang)、監視、控(kong)(kong)制和(he)(he)保護的設備(bei)(bei)，它主要由包括繼(ji)電(dian)保護裝置、自動裝置、測控(kong)(kong)裝置、計量(liang)裝置等(deng)設備(bei)(bei)。從個真正意義上的電(dian)力(li)系(xi)統建立開(kai)始(shi)就(jiu)出現了(le)變(bian)(bian)電(dian)站，變(bian)(bian)電(dian)站作(zuo)為(wei)電(dian)力(li)系(xi)統不(bu)可(ke)或(huo)缺的部(bu)分，變(bian)(bian)電(dian)站在建造場地、電(dian)壓等(deng)級、設備(bei)(bei)情況(kuang)等(deng)方面都發(fa)生了(le)巨大的變(bian)(bian)化(hua)。

變電(dian)(dian)(dian)站(zhan)工作：值班人(ren)員(yuan)(或值班班)接到日程(cheng)命(ming)令(ling)后錄音(yin)，將(jiang)作業(ye)任務(wu)交給(gei)此次操作員(yuan)，聽日程(cheng)命(ming)令(ling)錄音(yin)，由(you)監督人(ren)員(yuan)填寫命(ming)令(ling)記錄。變電(dian)(dian)(dian)站(zhan)應根據運行設(she)(she)備的(de)實際(ji)工況，變電(dian)(dian)(dian)站(zhan)哪家好，并(bing)總結以往(wang)處理設(she)(she)備事故、障礙(ai)和(he)缺陷的(de)經(jing)驗教(jiao)訓，制定出具體的(de)檢(jian)查方法。高低壓配(pei)電(dian)(dian)(dian)室(shi)、電(dian)(dian)(dian)容器室(shi)及(ji)變壓器室(shi)的(de)門應向外開，相鄰兩配(pei)電(dian)(dian)(dian)室(shi)的(de)門應雙向開啟，配(pei)電(dian)(dian)(dian)室(shi)、電(dian)(dian)(dian)容器室(shi)、變壓器室(shi)及(ji)主控室(shi)應設(she)(she)置防范雨、雪、等從門等入室(shi)的(de)設(she)(she)施。

變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)是(shi)指電(dian)(dian)(dian)(dian)(dian)(dian)力系統中(zhong)對電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)和電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)進行(xing)變(bian)(bian)(bian)換，接受電(dian)(dian)(dian)(dian)(dian)(dian)能及分配電(dian)(dian)(dian)(dian)(dian)(dian)能的(de)場所(suo)。在(zai)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)廠內的(de)變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)是(shi)升壓(ya)變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)，其作用是(shi)將(jiang)發(fa)電(dian)(dian)(dian)(dian)(dian)(dian)機發(fa)出的(de)電(dian)(dian)(dian)(dian)(dian)(dian)能升壓(ya)后(hou)饋送到高壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)網中(zhong)。一類變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)。是(shi)指交流(liu)特高壓(ya)站(zhan)，、大(da)(da)型(xing)能源基(ji)地（300萬kw及以上(shang)）外送及跨(kua)大(da)(da)區(qu)（華(hua)北(bei)、華(hua)中(zhong)、華(hua)東、東北(bei)、西北(bei)）聯絡750/500/330kV變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)。從個真正(zheng)意義(yi)上(shang)的(de)電(dian)(dian)(dian)(dian)(dian)(dian)力系統建(jian)立開始就出現了(le)變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)，變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)作為(wei)電(dian)(dian)(dian)(dian)(dian)(dian)力系統不可或缺的(de)部分，變(bian)(bian)(bian)電(dian)(dian)(dian)(dian)(dian)(dian)站(zhan)在(zai)建(jian)造場地、電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)等(deng)(deng)級、設備情況(kuang)等(deng)(deng)方面都發(fa)生了(le)巨大(da)(da)的(de)變(bian)(bian)(bian)化(hua)。
