本公(gong)司(si)是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)行業中電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)設備、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)技術、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)配套服務(wu)提供(gong)者(zhe)，其中，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)(li)設備（power system）主要(yao)(yao)包括發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備和供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備兩大類(lei)，發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備主要(yao)(yao)是電(dian)(dian)(dian)(dian)(dian)(dian)(dian)站鍋爐、蒸汽(qi)輪機(ji)(ji)、燃氣輪機(ji)(ji)、水輪機(ji)(ji)、發(fa)(fa)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)(ji)、變壓器(qi)等等，供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)設備主要(yao)(yao)是各(ge)種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓等級(ji)的輸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)線路、互感器(qi)、接觸器(qi)等等。

電(dian)(dian)力系統(tong)中的電(dian)(dian)力設備(bei)很多，根據(ju)他們在(zai)運行(xing)中所起的作用(yong)不(bu)同(tong)，通常將他們分為電(dian)(dian)氣(qi)一次(ci)設備(bei)和電(dian)(dian)氣(qi)二次(ci)設備(bei)。

電力一次設備

直接參(can)與生產、變換、傳輸、分(fen)配和消(xiao)耗電(dian)能(neng)的設(she)備稱為(wei)電(dian)氣一次設(she)備，主要有：

進行電(dian)能生產和變換的設備，如發電(dian)機、電(dian)動機、變壓器等；

接通、斷開電(dian)路的開關電(dian)器(qi)，如斷路器(qi)、隔(ge)離開關、接觸器(qi)、熔(rong)斷器(qi)等

載流導體(ti)及氣體(ti)絕(jue)緣設備。如母線(xian)、電力(li)電纜(lan)、絕(jue)緣子、穿(chuan)墻套管等

限制過電流(liu)或(huo)過電壓的設備，如(ru)限流(liu)電抗器、避雷器等

互(hu)感器類(lei)設(she)備：將一次(ci)回(hui)路中的高電(dian)(dian)壓和大電(dian)(dian)流降低，供測(ce)量(liang)儀表和繼電(dian)(dian)保護裝置(zhi)使用，如(ru)電(dian)(dian)壓互(hu)感器、電(dian)(dian)流互(hu)感器。

電力二次設備

為(wei)(wei)了保護保證電氣一次(ci)設(she)備(bei)(bei)的正常(chang)運行(xing)，對其運行(xing)狀(zhuang)態進行(xing)測(ce)量、監視(shi)、控(kong)制和調節等(deng)的設(she)備(bei)(bei)稱為(wei)(wei)電氣二次(ci)設(she)備(bei)(bei)。主(zhu)要有各(ge)種測(ce)量表計，各(ge)種繼(ji)電保護及自動裝置，直流(liu)電源設(she)備(bei)(bei)等(deng)。
