Insulators ua lub luag haujlwm tseem ceeb hauv kev tswj xyuas kev nyab xeeb thiab kev ua haujlwm ntawm cov kab hluav taws xob. Lawv yog cov ntaub ntawv uas tsis yog-conductive uas yog siv los cais cov nqi hluav taws xob los ntawm lub ntiaj teb lossis lwm yam khoom siv hluav taws xob. Cov insulators tiv thaiv hluav taws xob los ntawm kev tsis xav tau, yog li tsis txhob poob siab, luv luv Circuit Court, thiab kev puas tsuaj rau lub zog hluav taws xob. Rau cov hluav taws xob hluav taws xob hluav taws xob siab, cov hluav taws xob hluav taws xob yuav tsum tau tsim tshwj xeeb los tiv thaiv ib puag ncig hnyav thiab kev ntxhov siab uas tshwm sim hauv cov kab hluav taws xob overhead.
Nyob rau hauv 33kV fais fab kis kab, cov insulators yog cov khoom tseem ceeb uas yog lub luag hauj lwm rau kev tswj cov hluav taws xob rwb thaiv tsev uas yuav tsum tau thiab txhua yam muaj zog ntawm cov conductors thiab cov yees. Hom insulators siv nyob rau hauv 33kV kab yog ua los ntawm porcelain los yog iav. Nyob rau hauv tsab xov xwm no, peb yuav tham txog cov khoom thiab qhov zoo ntawm cov ntaub ntawv insulator thiab lawv qhov tsim nyog rau 33kV fais fab kab daim ntawv thov.
Porcelain Insulators
Porcelain insulators tau siv rau hauv lub tshuab xa hluav taws xob rau ntau tshaj ib puas xyoo. Porcelain yog cov khoom siv ceramic uas yog tsim los ntawm kev tua cov av nplaum sib xyaw, feldspar, thiab lwm yam khoom ntxiv ntawm qhov kub thiab txias. Porcelain insulators rau 33kV kab feem ntau yog tsim los ua disc insulators lossis post insulators. Disc insulators feem ntau yog siv rau hauv daim ntawv thov ncua kev kawm ntawv thiab post insulators yog siv nyob rau hauv daim ntawv thov nro.
Porcelain insulators yog nyiam rau cov kab hluav taws xob sib kis tau zoo vim tias lawv cov khoom siv hluav taws xob zoo heev thiab cov khoom siv dag zog. Porcelain muaj lub zog dielectric siab, uas txhais tau hais tias nws tuaj yeem tiv taus qhov hluav taws xob siab yam tsis tau tawg. Lub zog txhua yam ntawm cov plooj (porcelain) kuj yog siab heev, tso cai rau nws tiv taus cov khoom hnyav uas raug yuam rau nws los ntawm cov neeg xyuas pib thiab cua.
Porcelain insulators tseem tiv taus huab cua thiab kev laus, uas ua rau lawv zoo tagnrho rau kev siv sab nraum zoov. Qhov saum npoo ntawm cov plooj (porcelain insulator) yog coated nrog cov glaze uas repels dej thiab tiv thaiv cov tsub zuj zuj ntawm cov kab mob xws li plua plav, av, thiab noog poob. Qhov no pab tswj cov hluav taws xob rwb thaiv tsev cov khoom ntawm cov insulator nyob rau lub sijhawm ntev.
iav Insulators
Iav insulators yog lwm hom insulator uas feem ntau siv rau hauv cov kab hluav taws xob sib txuas. Iav insulators muaj ntau qhov zoo dua li cov porcelain insulators, nrog rau kev ua kom muaj kuab paug ntau dua thiab khaws cov xim zoo dua.
Iav insulators yog tsim los ntawm cua sov sib tov ntawm silica, limestone, thiab lwm yam additives rau kub kub. Tom qab ntawd lub khob yog molded los yog nias rau hauv cov duab uas xav tau. Iav insulators rau 33kV kab feem ntau yog tsim los ua lub hau thiab tus pin insulators los yog ncua kev kawm ntawv insulators.
Lub ntsiab kom zoo dua ntawm iav insulators yog lawv lub peev xwm los tiv thaiv kev kis kab mob los ntawm plua plav, ntsev, thiab lwm yam kuab paug. Cov iav insulators muaj qhov smoother dua li cov plooj (porcelain insulators), uas ua rau nws nyuaj rau cov av thiab lwm yam kab mob kom ua raws li lawv. Qhov no txo qhov kev pheej hmoo ntawm flashover, ib qho tshwm sim uas ib qho hluav taws xob arc mus ncig ntawm qhov chaw ntawm lub insulator, ua rau luv luv.
Cov iav insulators kuj muaj xim zoo dua li cov iav insulators. Cov xim ntawm cov iav insulator tseem ci thiab meej txawm tias tom qab ntau xyoo raug tshav ntuj thiab huab cua. Qhov no ua rau nws yooj yim dua los tshuaj xyuas cov insulators rau cov cim qhia ntawm kev puas tsuaj lossis kev sib kis.
Kev xaiv ntawm insulator rau 33kV fais fab kis kab yuav nyob ntawm ntau yam, nrog rau cov xwm txheej ib puag ncig, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob rwb thaiv tsev. Porcelain thiab iav insulators yog ob qho kev xaiv zoo rau 33kV kab, thiab txhua tus muaj nws tus kheej qhov zoo thiab qhov tsis zoo. Qhov tseem ceeb yog xaiv ib qho insulator uas tuaj yeem muab kev ntseeg tau zoo nyob rau lub sijhawm ntev, nrog kev tu thiab kho me me. Los ntawm kev xaiv cov khoom siv hluav taws xob zoo, cov khoom siv hluav taws xob tuaj yeem ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm lawv cov hluav taws xob xa hluav taws xob, thiab tswj kom muaj kev ntseeg tau ntawm hluav taws xob rau lawv cov neeg siv khoom.
