Kev siv hluav taws xob yog qhov tsis sib luag ntawm cov neeg niaj hnub, ib qho yuav tsum tau nrog nws tas li rau lub neej niaj hnub thiab tom haujlwm. Yog li hluav taws xob txuas ntxiv ua tus pab cuam thiab tsis tig ua yeeb ncuab ntawm tus txiv neej, tsis hem nws cov cuab yeej nrog hluav taws, muaj teeb tsa kev ntsuas hluav taws xob tiv thaiv kev nyab xeeb. Nws lub ntsiab tseem ceeb suav hais tias yog qhov zoo ntawm kev rwb thaiv tsev ntawm tus neeg xyuas pib, sib npaug ntawm:
- insulating sheaths ntawm conductive cores hauv cov xaim hluav taws xob;
- rwb thaiv tsev ntawm cov tswj nyob rau hauv tswj cables;
- kev tiv thaiv hluav taws xob thaiv ntawm cov xaim hluav taws xob sab hauv (hluav taws xob thaiv hluav taws xob).
Ntawm tsis muaj qhov tseem ceeb me me yog qhov zoo ntawm lub rwb thaiv tsev ntawm cov khoom siv hluav taws xob, uas ua kom muaj kev tiv thaiv ntawm nws lub cev conductive los ntawm lub ingress ntawm cov phom sij theem ntawm lawv thiab qhov ua rau puas tsuaj ntawm cov hluav taws xob tam sim no.
Hmoov tsis zoo, muaj ntau ntau yam ua rau poob ntawm cov kab uas tsis muaj insulating:
- qhov cuam tshuam ntawm ib puag ncig sab nraud (huab cua siab, ntsuas kub hloov, muaj cov khoom hnyav, hluav taws xob, suav nrog hnub ci);
- xwm txheej tsis tu ncua ntawm lub peev xwm ntawm tus neeg xyuas pib, ua rau lawv sov tuaj;
- Lub sijhawm ua haujlwm ntev nrog kev laus ua tsis taus ntawm kev rwb thaiv tsev;
- cov tsos ntawm kev puas tsuaj ntawm cov tshuab thaum lub sijhawm ua haujlwm lossis kho, ua haujlwm tsis pom kev tsis zoo (lub Hoobkas ua haujlwm).
Kev txiav txim siab ntawm cov kab hluav taws xob tiv thaiv yog nrog lub suab qis qis qis resistances, yog li ntawd kev ua haujlwm kev sib tw ntawm cov cuab yeej hluav taws xob ib txwm nrog kev ntsuas kev ntsuas ntawm rwb thaiv tsev tsis kam.
Cov txheej txheem thiab ntau zaus ntawm kev ntsuas ntawm kev ntsuas rwb thaiv tsev
Qhov xav tau ntawm cov qhov tseem ceeb ntawm kev tiv thaiv rwb thaiv tsev tau npaj tawm hauv ntau cov ntaub ntawv kev cai, tshwj xeeb, lawv raug tswj los ntawm rooj 38 ntawm Cov Lus Qhia 3.1 PTEEP. Nws qhov tsawg kawg nkaus tus nqi yuav tsum tsis txhob rho tawm, piv txwv:
- qis dua 0.5 MΩ rau cov tes hauj lwm teeb pom kev zoo;
- tsawg dua 1 megohm rau cov tshuab hluav taws xob nyob ruaj ruaj.
Thaum ntsuas cov rwb thaiv tsev tsis kam nyob rau hauv ib-tes hauj lwm, kev ntsuas raug coj ntawm cov khub hauv qab no:
- xoom thiab theem xov hluav taws xob;
-phase thiab kev tiv thaiv grounding PE;
- xoom thiab earthen.
Yog li, peb txoj kev ntsuas raug tsim, thaum nyob hauv peb-theem qhov hluav taws xob hluav taws xob, kev tiv thaiv rwb thaiv tsev yuav tau ntsuas 10 zaug.
Rau kev nyab xeeb ntawm cov cuab yeej hluav taws xob thiab txhawm rau kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm, kev tiv thaiv rwb thaiv tsev yog ntsuas los ntawm kev txiav tawm cov hluav taws xob hluav taws xob los ntawm lub zog hluav taws xob ntawm cov khoom siv thiab cuam tshuam txhua lub ntim. Yog tias cov kab uas muaj qhov tsis tshua muaj hluav taws xob tiv thaiv tau raug kuaj pom, qhov chaw tsis raug nyob hauv ib cheeb tsam los ntawm qhov kev txiav txuas ntawm cov kab ntu hauv cov kev taw qhia rov qab rau lub hauv paus. Txhua qhov ntsuas thaum xaus nrog kev tso npe ntawm kev ntsuas cov ntsuas.
Rwb thaiv tsev resistances ntsuas nrog ib megohmmeter, ib qho khoom siv tshwj xeeb rau kev ntsuas qhov siab qhov siab.
Qhov ntau zaus ntawm kev coj ua ntsuas kev ntsuas kev ntsuas ntawm rwb thaiv tsev rau kev tiv taus yog nyob ntawm lub hom phiaj ntawm kev siv hluav taws xob, lawv qhov tseem ceeb thiab kev ua haujlwm. Yog li rau chav tshwj xeeb tshaj yog muaj huab cua noo, qhov kub thiab qhov dav ntawm cov plag tsev nyob hauv av, nws yog qhov tsim nyog los ntsuas kev rwb thaiv tsev tsawg kawg ib xyoos ib zaug. Cov menyuam yaus thiab cov tsev kho mob, cov nce tsheb thiab ntau lub tsev ntxiv tseem ceeb nrog cov xwm txheej zoo sib xws.
Ntawm qhov chaw muaj kev phom sij tsawg tsawg (cov chaw haujlwm, cov tuam tsev chav tsev), kev ntsuas tau tsawg dua - ib zaug txhua peb xyoos.
Raws li cov kev cai nruj, qhov nyuaj thiab lub luag haujlwm siab ntawm kev ntsuas kev ntsuas lub rwb thaiv tsev, hom kev pabcuam no yuav tsum ntseeg siab tshwj xeeb los ntawm cov tuam txhab muaj ntawv pov thawj. Cov neeg yuav khoom los ntawm Moscow thiab Moscow Thaj Tsam yuav tsum them sai sai rau CenterEnergoEkspertizy LLC, cov ntawv tso cai, lub xeev ntawm kev tsim hluav taws xob thiab cov neeg ua haujlwm muaj peev xwm lees paub kev nyab xeeb ntawm koj cov tes hauj lwm. Cov kev pabcuam tuaj yeem txiav txim rau lub tuam txhab lub vev xaib https://cenerg.ru/
