本公(gong)司(si)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)行業中(zhong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)設(she)(she)備(bei)(bei)、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)技術、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)配套服務提(ti)供(gong)(gong)者(zhe)，其中(zhong)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)設(she)(she)備(bei)(bei)（power system）主要包括發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)(bei)和供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)(bei)兩(liang)大類，發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)(bei)主要是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)站鍋爐、蒸(zheng)汽輪機(ji)、燃氣(qi)輪機(ji)、水(shui)輪機(ji)、發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)機(ji)、變壓(ya)器等等，供(gong)(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)設(she)(she)備(bei)(bei)主要是(shi)(shi)各種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)等級的(de)輸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)線(xian)路、互感器、接觸(chu)器等等。

電(dian)力系統中的電(dian)力設備(bei)(bei)很多，根據他(ta)們在(zai)運行(xing)中所起的作用不同，通常將他(ta)們分為電(dian)氣(qi)一(yi)次(ci)設備(bei)(bei)和電(dian)氣(qi)二次(ci)設備(bei)(bei)。

電力一次設備

直接參與(yu)生(sheng)產、變換(huan)、傳輸(shu)、分配和消耗電能(neng)的設備稱為電氣一次(ci)設備，主要有：

進行電能(neng)生產和變(bian)(bian)換的(de)設備(bei)，如發電機、電動機、變(bian)(bian)壓器等；

接(jie)通、斷(duan)開(kai)電(dian)路的開(kai)關電(dian)器(qi)，如斷(duan)路器(qi)、隔離(li)開(kai)關、接(jie)觸器(qi)、熔斷(duan)器(qi)等

載(zai)流導體(ti)及氣體(ti)絕(jue)緣(yuan)設備(bei)。如母線(xian)、電力(li)電纜、絕(jue)緣(yuan)子(zi)、穿墻套管等

限(xian)制(zhi)過電流或過電壓的設備(bei)，如(ru)限(xian)流電抗器、避雷器等

互感器類(lei)設(she)備(bei)：將一次(ci)回路中的高(gao)電壓和大電流降低(di)，供測量儀表和繼電保護裝(zhuang)置使用，如(ru)電壓互感器、電流互感器。

電力二次設備

為了保(bao)護保(bao)證電氣(qi)一次(ci)設備的正常運行，對(dui)其(qi)運行狀態進行測量、監視、控制和調節等的設備稱為電氣(qi)二(er)次(ci)設備。主要有各種測量表計，各種繼電保(bao)護及自動裝置，直(zhi)流(liu)電源設備等。
