繼電器及裝置有需要經常(chang)予以監督的(de)缺陷與薄(bo)弱(ruo)環節，或(huo)者(zhe)運(yun)行(xing)環境差、運(yun)行(xing)經驗(yan)(yan)不足，或(huo)者(zhe)運(yun)行(xing)狀(zhuang)態不穩(wen)定(ding)時，可適當(dang)縮短(duan)檢(jian)(jian)驗(yan)(yan)周(zhou)期，而(er)在制造質量好(hao)、運(yun)行(xing)情況好(hao)時，可考(kao)慮適當(dang)延(yan)長檢(jian)(jian)驗(yan)(yan)周(zhou)期。除按照檢(jian)(jian)驗(yan)(yan)周(zhou)期的(de)規定(ding)進行(xing)定(ding)期全部檢(jian)(jian)驗(yan)(yan)外，根據檢(jian)(jian)驗(yan)(yan)條例要求(qiu)，每(mei)年還必須(xu)進行(xing)一次(ci)(ci)部分檢(jian)(jian)驗(yan)(yan)及每(mei)年不少(shao)于一次(ci)(ci)作(zuo)用于斷路器的(de)跳合閘試驗(yan)(yan)，重點考(kao)核整(zheng)組動作(zuo)性能是(shi)否正(zheng)常(chang)。

試(shi)驗(yan)所(suo)采(cai)用的交流試(shi)驗(yan)電源(yuan)必須保證具有良(liang)好的波(bo)形，加入繼電器(qi)的電壓和電流的波(bo)形應(ying)(ying)為正弦波(bo)，不(bu)(bu)得(de)有畸變(bian)現象；交流試(shi)驗(yan)電源(yuan)和相應(ying)(ying)的調(diao)整(zheng)設備(bei)應(ying)(ying)有足夠的容(rong)量，保證作大負載試(shi)驗(yan)時電源(yuan)波(bo)形不(bu)(bu)會畸變(bian)；還應(ying)(ying)注意在進(jin)行試(shi)驗(yan)時應(ying)(ying)盡量取相同的電壓作試(shi)驗(yan)電源(yuan)，調(diao)整(zheng)電流時采(cai)用電阻器(qi)調(diao)節的方(fang)法(fa)；在對繼電器(qi)進(jin)行整(zheng)定試(shi)驗(yan)時，所(suo)用儀表的精度(du)應(ying)(ying)不(bu)(bu)低于０.５級(ji)。美國邦納banner繼電器正品

二位(wei)置(zhi)偏倚計劃繼(ji)電(dian)(dian)(dian)器：繼(ji)電(dian)(dian)(dian)器線圈斷電(dian)(dian)(dian)時，銜(xian)鐵(tie)恒靠在(zai)一邊；線圈通電(dian)(dian)(dian)時，銜(xian)鐵(tie)被 吸(xi)向(xiang)另一邊。 新安(an)裝驗(yan)(yan)收檢驗(yan)(yan)在(zai)繼(ji)電(dian)(dian)(dian)器新安(an)裝時進(jin)行(xing)(xing)。新安(an)裝驗(yan)(yan)收檢驗(yan)(yan)時，要求對繼(ji)電(dian)(dian)(dian)器進(jin)行(xing)(xing)全面檢查試驗(yan)(yan)，以保證繼(ji)電(dian)(dian)(dian)器投入運(yun)行(xing)(xing)后的(de)性(xing)能和質量滿(man)足(zu)要求。三位(wei)置(zhi)極化繼(ji)電(dian)(dian)(dian)器：繼(ji)電(dian)(dian)(dian)器線圈通電(dian)(dian)(dian)時，銜(xian)鐵(tie)按線圈電(dian)(dian)(dian)流方向(xiang)被吸(xi)向(xiang)左邊或(huo)右邊的(de)位(wei)置(zhi)；線圈斷電(dian)(dian)(dian)后，是(shi)返回到中間位(wei)置(zhi)。
