隨著經(jing)濟的發(fa)展,，高(gao)科技設備(bei)獲得了廣泛的應用。這(zhe)些設備(bei)對電(dian)(dian)(dian)(dian)壓(ya)變化很(hen)敏(min)感,短時的供(gong)電(dian)(dian)(dian)(dian)中斷(duan)或電(dian)(dian)(dian)(dian)壓(ya)有(you)效值下降往往會造成設備(bei)不正常(chang)運行(xing)，發(fa)生停機等事(shi)故。電(dian)(dian)(dian)(dian)壓(ya)暫降是針對這(zhe)一問題而提出的。所以，靜(jing)止無功發(fa)生器(qi)的補償作用對電(dian)(dian)(dian)(dian)力系(xi)(xi)統有(you)著非(fei)常(chang)重要的意義，對電(dian)(dian)(dian)(dian)力系(xi)(xi)統適當地用靜(jing)止無功發(fa)生器(qi)，起到穩定電(dian)(dian)(dian)(dian)網(wang)電(dian)(dian)(dian)(dian)壓(ya)，提高(gao)功率因數(shu)，減小(xiao)網(wang)絡有(you)功功率的損耗，提高(gao)線路輸電(dian)(dian)(dian)(dian)能力，平衡三相功率的作用。

環(huan)境溫(wen)(wen)(wen)度(du)的(de)影響。電(dian)(dian)(dian)容(rong)器(qi)(qi)的(de)運行(xing)溫(wen)(wen)(wen)度(du)是運行(xing)人員重(zhong)(zhong)要的(de)監視項目。溫(wen)(wen)(wen)度(du)不(bu)超出允許范圍是保證(zheng)電(dian)(dian)(dian)容(rong)器(qi)(qi)安(an)全運和達到(dao)預定(ding)(ding)使用年(nian)限的(de)重(zhong)(zhong)要條(tiao)件。運行(xing)溫(wen)(wen)(wen)度(du)過高，導致介質(zhi)擊(ji)穿強度(du)的(de)降低，或介質(zhi)損(sun)耗的(de)迅速增加。若溫(wen)(wen)(wen)升持續，將(jiang)破壞(huai)熱平(ping)衡，造成熱擊(ji)穿。而在低溫(wen)(wen)(wen)條(tiao)件下，電(dian)(dian)(dian)容(rong)器(qi)(qi)內部(bu)將(jiang)是負壓，游離(li)電(dian)(dian)(dian)壓會下降。因此，不(bu)同地(di)(di)區(qu)電(dian)(dian)(dian)力(li)部(bu)門根據當地(di)(di)氣候條(tiao)件參照電(dian)(dian)(dian)容(rong)器(qi)(qi)技術規定(ding)(ding)要求選擇相應類型，以(yi)保證(zheng)運行(xing)的(de)安(an)全。

其電阻(zu)率會發生明顯變化,通(tong)過檢(jian)測電阻(zu)的(de)(de)變化,就知道壓力的(de)(de)大小,在硅片的(de)(de)中間,從背面腐蝕形(xing)成了正方形(xing)的(de)(de)膜(mo)片,利用(yong)膜(mo)片將壓力轉換成應力,在膜(mo)片的(de)(de)表(biao)面,通(tong)過擴散雜質形(xing)成了四個p型(xing)測量電阻(zu),把它們(men)按橋式(shi)電路連接起來。
