Lub tswvyim ntawm tsib kev tiv thaiv:
1. Anti-load qhib thiab kaw disconnector;
2. Tiv thaiv kev qhib thiab kaw qhov tsis raug ntawm Circuit Court breaker;
3. Anti-load kaw grounding hloov;
4. Load kis tau tus mob thaum lub anti-grounding hloov yog kaw;
5. Tiv thaiv kom tsis txhob nkag mus rau qhov chaw nyob ua yuam kev.
Lub xauv tsib-tiv thaiv yog lub ntsuas phoo tau teeb tsa kom ua tiav qhov ntsuas tsib-tiv thaiv saum toj no.Txhawm rau ua tiav cov haujlwm tshwj xeeb ntawm tsib-tiv thaiv, nws tseem yuav tsum tau koom tes nrog microcomputer tsib-tiv thaiv kab ke lossis los ntawm cov neeg ua haujlwm nruj tsib-tiv thaiv kev ua haujlwm.
"Tsib hluav taws xob ceev faj" ntawm high-voltage switchgear:
"Interlocking" ntawm high-voltage switchgear yog ib qho kev ntsuas tseem ceeb los xyuas kom muaj kev nyab xeeb ntawm lub zog hluav taws xob, xyuas kom muaj kev nyab xeeb ntawm cov khoom siv thiab cov neeg ua haujlwm, thiab tiv thaiv kev ua haujlwm tsis zoo.GB3906-1991 "3 ~ 35 kV AC Hlau-pob Switchgear" tau ua cov kev cai meej rau qhov no.Feem ntau, "interlocking" yog piav raws li: tiv thaiv tsis raug qhib thiab kaw ntawm Circuit Court breaker;tiv thaiv qhib thiab kaw ntawm disconnector nrog load;tiv thaiv dai (kaw) ntawm cov xaim hauv av (grounding hloov) nrog lub zog;tiv thaiv kev kaw ntawm grounding hlau (hloov) nrog lub hwj chim;tiv thaiv kev nkag mus rau hauv qhov chaw nyob los ntawm kev yuam kev.Cov ntsiab lus saum toj no tsib los tiv thaiv kev siv hluav taws xob tsis zoo yog hu ua "tsib kev tiv thaiv"."tsib kev tiv thaiv" Cov cuab yeej siv feem ntau muab faib ua cov khoom siv hluav taws xob, hluav taws xob thiab kev qhia dav.Tam sim no, muaj ntau hom high-voltage switchgear nyob rau hauv kev ua lag luam, feem ntau ntawm cov uas muaj ncej zoo meej interlocking hom.
1. Tom qab lub tshuab nqus tsev vacuum breaker trolley nyob rau hauv high-voltage hloov txee kaw ntawm qhov chaw kuaj, lub trolley Circuit Court breaker tsis tuaj yeem nkag mus rau txoj haujlwm ua haujlwm.(Tsis txhob kaw nrog load).
2. Thaum lub qhov hluav taws xob hloov hluav taws xob hauv lub tshuab hluav taws xob hloov hluav taws xob kaw, lub trolley circuit breaker tsis tuaj yeem kaw.(Tsis txhob kaw nrog grounding hlau).
3. Thaum lub tshuab nqus tsev Circuit Court breaker nyob rau hauv high-voltage switchgear raug kaw, lub rear qhov rooj ntawm lub vaj huam sib luag thiab txee yog xauv nrog lub txee qhov rooj los ntawm lub mechanism ntawm lub hauv av riam.(Tsis txhob nkag mus rau qhov chaw nyob ua yuam kev).
4. Lub tshuab nqus tsev Circuit Court breaker nyob rau hauv high-voltage hloov txee yog kaw thaum lub sij hawm ua hauj lwm, thiab lub kaw grounding hloov tsis tau muab tso rau hauv lub lag luam.(Tsis txhob nyob dai ntawm cov xaim hauv av).
5. Lub tshuab nqus tsev Circuit Court breaker nyob rau hauv high-voltage hloov txee tsis tuaj yeem tawm ntawm qhov chaw ua haujlwm ntawm lub trolley circuit breaker thaum nws raug kaw.
