Daim ntawv thov ntawm lub thawv-hom hloov chaw

1. Mas siv hauv cov tsev kawm hauv nroog thiab hauv kev, thaum hluav taws xob siv thaum lub caij nyoog siab tshaj plaws. Thaum qhov voltage xav tau nce ntxiv, peb yuav tsum siv peb cov khoom siv-thawv-hom hloov chaw.

2. Siv cov khoom siv hluav taws xob ib ntus, xws li hauv cov chaw tsim kho, nyob rau hauv cov tuam tsev uas twb muaj lawm, peb yuav tsum hloov cov khoom siv hluav taws xob. Box-type substations feem ntau siv hauv kev ua haujlwm hauv thaj chaw, xws li chaw tsim kho tsev, docks, tshav dav hlau, thiab lwm yam.

General kev cai

⑴Txoj kev yooj yim ntawm cov teeb pom kev zoo thiab kev faib hluav taws xob rau pej xeem, qhov ntsuas hluav taws xob loj tsis tsim nyog rau hauv cov hluav taws xob uas muaj hluav taws xob ntau ntawm lub thawv hloov cov tshuab, tsuas yog hluav taws xob tsis tshua muaj hluav taws xob los yog tsis ntsuas, tsis muaj nyiaj them rov qab. 4 ~ 6 lub tswv yim loops raug tswj thiab tiv thaiv los ntawm yas Circuit Court tej fais fab;

⑵ Hauv qhov hluav taws xob pej xeem muab hluav taws xob rau lub teeb pom kev zoo hluav taws xob, qhov hluav taws xob faib ntawm lub thawv hloov pauv tau nce, nce txog 8-12 zaug. Tsis tas li ntawd, nws yuav tsum muaj lub zog tsim nyog tau nyiaj them rov ua haujlwm;

Kev tswj tus kheej tus nqi hluav taws xob thiab cov xwm txheej tshwj xeeb.

Lub thawv-hom hloov chaw nyob cheeb tsam me me. Cov kab ntawm lub thawv dav dav dav npog thaj tsam tsuas yog 5 ~ 6㎡, thiab nws tuaj yeem txo tau 3 ~ 3.5㎡. Nws yog qhov tsim nyog rau cov chaw xws li cov chaw thau khoom dav dav-kev lag luam thiab cov chaw lag luam mining, chaw nres nkoj thiab thaj chaw nyob, uas tuaj yeem txuas hluav taws xob ntau rau cov chaw xa khoom, txo cov hluav taws xob ntawm cov hluav taws xob tsawg, thiab txo kev poob. Muaj ob peb cov kab hluav taws xob tsis tshua muaj zog, feem ntau 4 ~ 6 kab. Ua kom luv ntawm qhov chaw tsim kho ua haujlwm thiab txo kev nqis peev.

Thaum cov khoom siv tshiab xws li cov tshuab hluav taws xob puv hloov pauv thiab SF6 hloov lub thawv siv, lub sijhawm txij nkawm ntawm cov khoom tuaj yeem txuas ntxiv, thiab cov kev tswj hwm tsis pub muaj peev xwm ua tiav. Cov tsos yog yam tshiab thiab zoo nkauj, uas tuaj yeem ua kom sib haum nrog ib puag ncig ib puag ncig ntawm kev hloov chaw. Lub tuam tsev saib xyuas hluav taws xob hauv nroog yuav tsum tau ntsuas hluav taws xob ntsuas siab rau lub thawv kev tswj tus kheej (250kVA lossis siab tshaj 315kVA). Hauv lwm qhov xwm txheej, kev faib tawm ntawm ntau lub voj voog suav nrog kev muab cov circuits thaub qab. Nyob rau cov xwm txheej no, cov neeg tsim qauv yuav ua kom zoo tshaj plaws ntawm kev tsim qauv los ntawm kev ntsuas cov qauv xaiv los ntawm cov chaw tsim khoom raws li kev siv hluav taws xob tiag tiag.
