二.安裝(zhuang)及使用(yong)(yong)(yong)須(xu)知(zhi):l本電(dian)(dian)力調(diao)整器(qi)(qi)是壁掛式(shi)，工作環(huan)境(jing)(jing)溫度：0℃～+55℃，工作環(huan)境(jing)(jing)相對濕度：*90%。l需垂直安裝(zhuang)在(zai)(zai)通風良好，不(bu)受日光直射(she)或熱輻射(she)，無(wu)腐蝕性(xing)無(wu)可燃性(xing)的(de)(de)環(huan)境(jing)(jing)中(zhong)。l工作電(dian)(dian)流>30A,需采用(yong)(yong)(yong)強制風冷。高溫高濕以及海拔(ba)大于(yu)1000米，應降額使用(yong)(yong)(yong)。l裝(zhuang)置過(guo)熱保(bao)護后，如(ru)要再運(yun)行，需排除故(gu)障后，再送電(dian)(dian)運(yun)行。三.初步調(diao)試：參照圖接線，先(xian)用(yong)(yong)(yong)100～200W燈泡假負(fu)(fu)載(zai)，將(jiang)儀表(biao)置手動方(fang)式(shi)。此時，負(fu)(fu)載(zai)電(dian)(dian)壓(ya)應在(zai)(zai)開關電(dian)(dian)壓(ya)范圍內通斷。常見(jian)故(gu)障排除：無(wu)控制信號不(bu)接負(fu)(fu)載(zai)時，R-U、S-V、T-W間(jian)三個(ge)固(gu)(gu)態繼電(dian)(dian)器(qi)(qi)間(jian)的(de)(de)阻值，用(yong)(yong)(yong)萬用(yong)(yong)(yong)表(biao)測量(liang)分別>500KΩ，當調(diao)節器(qi)(qi)輸出時，用(yong)(yong)(yong)萬用(yong)(yong)(yong)表(biao)測量(liang)R-U、S-V、T-W三個(ge)固(gu)(gu)態繼電(dian)(dian)器(qi)(qi)間(jian)的(de)(de)阻值應<10KΩ（以上數據(ju)*供參考）。,若SSR毀(hui)壞(huai)，無(wu)更換(huan)(huan)整機(ji)的(de)(de)必要.打(da)開機(ji)殼，可更換(huan)(huan)單只毀(hui)壞(huai)的(de)(de)SSR。緊(jin)急情況下，兩相控三相是可用(yong)(yong)(yong)的(de)(de)。

導致電(dian)(dian)(dian)(dian)流(liu)劇增、波形嚴重畸(ji)變(bian)(bian)、出(chu)現怪聲(sheng)，需重新(xin)設計變(bian)(bian)壓(ya)(ya)(ya)器。此外，實際應用(yong)(yong)中(zhong)(zhong)采(cai)用(yong)(yong)比較大電(dian)(dian)(dian)(dian)流(liu)限(xian)制，可(ke)(ke)解(jie)決線性(xing)或(huo)變(bian)(bian)阻負(fu)載(zai)(zai)的(de)(de)某一(yi)溫(wen)(wen)(wen)度段(duan)的(de)(de)電(dian)(dian)(dian)(dian)流(liu)突增，造(zao)成變(bian)(bian)壓(ya)(ya)(ya)器過流(liu)。2).電(dian)(dian)(dian)(dian)感中(zhong)(zhong)電(dian)(dian)(dian)(dian)流(liu)滯(zhi)后(hou)，造(zao)成負(fu)載(zai)(zai)電(dian)(dian)(dian)(dian)流(liu)在(zai)窄脈沖觸(chu)(chu)發時間(jian)內不能到達(da)使晶(jing)閘管(guan)保持有(you)效(xiao)開通(tong)的(de)(de)擎駐電(dian)(dian)(dian)(dian)流(liu)、因而觸(chu)(chu)發不可(ke)(ke)靠。采(cai)用(yong)(yong)脈寬可(ke)(ke)變(bian)(bian)直流(liu)觸(chu)(chu)發技(ji)術，加大阻容吸收數值和在(zai)變(bian)(bian)壓(ya)(ya)(ya)器原邊并聯阻性(xing)假負(fu)載(zai)(zai)，才能確(que)保可(ke)(ke)靠觸(chu)(chu)發。3).采(cai)用(yong)(yong)進口晶(jing)閘管(guan)，具(ju)(ju)有(you)開通(tong)速(su)度快、對稱性(xing)好、di/dt和dv/dt高、熱穩定(ding)性(xing)好、抗干擾能力強(qiang)等(deng)(deng)優點。4).運行過程中(zhong)(zhong)瞬間(jian)斷電(dian)(dian)(dian)(dian)后(hou)又上電(dian)(dian)(dian)(dian)等(deng)(deng)，造(zao)成變(bian)(bian)壓(ya)(ya)(ya)器中(zhong)(zhong)磁(ci)(ci)(ci)通(tong)極性(xing)與(yu)(yu)剩磁(ci)(ci)(ci)極性(xing)的(de)(de)“撞車(che)”，產生危(wei)害性(xing)沖擊電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)、電(dian)(dian)(dian)(dian)流(liu)。尤其是變(bian)(bian)壓(ya)(ya)(ya)器，必須采(cai)用(yong)(yong)上電(dian)(dian)(dian)(dian)緩起動逐步順磁(ci)(ci)(ci)，緩關(guan)斷逐步衰減(jian)磁(ci)(ci)(ci)場5).純金屬類(lei)：硅(gui)鉬、鉬絲、鎢、白金、石(shi)墨(mo)等(deng)(deng)負(fu)載(zai)(zai)冷(leng)態電(dian)(dian)(dian)(dian)阻小，低、中(zhong)(zhong)溫(wen)(wen)(wen)段(duan)需限(xian)壓(ya)(ya)(ya)和限(xian)流(liu)；隨著溫(wen)(wen)(wen)度增高，電(dian)(dian)(dian)(dian)阻按線性(xing)增大，在(zai)高溫(wen)(wen)(wen)段(duan)反而需增加負(fu)載(zai)(zai)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)。BHC6M-2的(de)(de)電(dian)(dian)(dian)(dian)流(liu)限(xian)制與(yu)(yu)恒(heng)流(liu)控制功能，可(ke)(ke)解(jie)決此類(lei)問題。此外，帶有(you)多(duo)組PID和調(diao)節輸(shu)出(chu)限(xian)幅的(de)(de)儀表，也可(ke)(ke)控制負(fu)載(zai)(zai)電(dian)(dian)(dian)(dian)流(liu)。例如：島電(dian)(dian)(dian)(dian)的(de)(de)FP73、FP21、SR253等(deng)(deng)可(ke)(ke)設計低、中(zhong)(zhong)、高溫(wen)(wen)(wen)區的(de)(de)調(diao)節輸(shu)出(chu)限(xian)制，SR50系列具(ju)(ju)有(you)調(diao)節輸(shu)出(chu)線性(xing)限(xian)幅,輸(shu)出(chu)能自動跟隨儀表的(de)(de)設定(ding)值線性(xing)增加。正高電(dian)(dian)(dian)(dian)氣愿和各界朋友真誠(cheng)合作一(yi)同(tong)開拓。
