Kev tsim hluav taws xob yog txheej txheem thev naus laus zis. Lub ntsiab ntawm lub tshuab no yog hloov ib hom zog mus rau lwm qhov. Yog li ntawd, nyob rau hauv thermal chaw, dej los yog chav rhuab mus rau ib tug tej yam kub rotates lub generator turbine, raws li ib tug tshwm sim ntawm cov hluav taws xob tam sim no. Tab sis kev tsim hluav taws xob tsis txaus. Peb yuav tsum xa nws mus rau tus neeg siv kawg. Rau lub hom phiaj no, cov kab hluav taws xob siv - cov kab hluav taws xob. Lub luag haujlwm tseem ceeb hauv kev tsim cov ntsiab lus yog ua si los ntawm kev txhawb nqa insulators. Txhawm rau muab nws yooj yim, lawv txoj haujlwm yog cais cov xaim nqa tam sim no thiab kev txhawb nqa.

Yuav kom cais lawv ntawm ib leeg, raug tshem tawm thiab kev txhawb nqa insulators. Tus tsim ntawm cov khoom yog xaiv nyob ntawm seb lub peev xwm ntawm cov kab. Ntawm cov kab hluav taws xob siv hluav taws xob nrog lub zog ntawm 110 kV thiab siab dua, tsuas yog siv cov kev xaiv tshem tawm. Txawm li cas los xij, txog thaum tsis ntev los no, cov txheej txheem cuam tshuam tau siv. Qhov tseeb yog tias cov khoom siv ib txwm siv rau kev tsim cov insulators yog tempered iav thiab porcelain. Raws li lawv lub cevcov yam ntxwv, lawv tiv taus siab tensile thiab compressive loads. Txawm li cas los xij, thaum khoov, lawv lub zog tsis txaus.

Cov khoom siv rau kev tsim cov insulators
Cov khoom siv rau kev tsim cov insulators

Rau cov kab hluav taws xob siv hluav taws xob nrog lub zog ntawm 35 kV thiab hauv qab no, cov khoom siv hluav taws xob tuaj yeem siv tau. Lawv tuaj yeem pom nyob ntawm cov ntoo thiab cov pob zeb ua vaj tse. Raws li cov cai tam sim no thiab cov kev cai, kev faib hluav taws xob rau cov neeg siv khoom tshwj xeeb yog ua los ntawm cov kab hluav taws xob uas muaj peev xwm ntawm 0.4 kV. Nyob rau hauv Russia, nyob rau hauv lub Soviet Union thiab niaj hnub no nyob rau hauv Lavxias teb sab Federation, tus qauv no tseem tsis tau hloov. Nyob rau hauv lub qhov hluav taws xob li niaj zaus, uas yog nyob rau hauv txhua chav tsev, lub mains voltage yog 220 V. Tag nrho cov khoom siv hauv tsev thiab ib feem tseem ceeb ntawm cov khoom siv yog xam raws li qhov ntsuas no.

Qhov twg insulators muaj txiaj ntsig ntau dua
Qhov twg insulators muaj txiaj ntsig ntau dua

Los ntawm kev tsim, ncej insulators yooj yim dua rau siv dua li cov khoom thaiv kev ncua. Txawm li cas los xij, ntawm high voltages, lawv cov yam ntxwv kev tsis muab qhov tsim nyog tsis. Qhov no twb tau tham saum toj no. Txhawm rau kom ua tiav cov txiaj ntsig tsim nyog, kev ua haujlwm tseem ceeb tab tom tsim los tsim cov ntaub ntawv tshiab thiab cov txheej txheem insulator siab dua. Hauv cov ntsiab lus no, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias nws yuav tsum ntseeg siab ua nws txoj haujlwm raws li txhua qhov kev ua haujlwm tau muab. Qhov no txhais tau hais tias nyob rau hauv high humidity tsis muaj luv luv Circuit Court ntawm kab rau hauv av.

Tam sim no, cov ntaub ntawv polymeric tau siv los ua cov khoom siv insulators. Piv nrogtsoos - iav thiab porcelain - lawv muaj ntau dua technologies thiab tsim tsis. Vim li no, tus nqi ntawm cov khoom lag luam tau txo qis thiab lawv cov kev ua haujlwm tau nce ntxiv. Tam sim no, thaum tsim cov kab hluav taws xob 110 kV, kev sib piv yuav ua tau los txiav txim siab seb cov insulators twg tau txais txiaj ntsig zoo dua los siv. Nws yuav tsum raug sau tseg tias kev txhim kho ntawm tus qauv tsim yuav tsum tau siv sijhawm ntau thiab cov peev txheej. Txhua tus qauv tshiab yuav tsum raug kuaj raws li kev ua haujlwm tiag tiag.
