Nyob rau hauv cov txheej txheem ntawm kev xa hluav taws xob, lub insulator plays lub luag haujlwm tseem ceeb hauv kev ua kom lub cev ua haujlwm ntawm cov kab sib txuas thiab txhim kho kev nyab xeeb thiab ruaj khov ntawm cov kab sib kis. Nrog rau kev nce ntawm cov kab sib txuas thiab qhov xav tau tiag tiag rau kev nyab xeeb thiab kev ruaj ntseg ntawm cov kab sib txuas, qhov kev thov rau cov kab hluav taws xob sib txuas tau maj mam nce. Txhawm rau ua kom tau raws li qhov xav tau tiag tiag ntawm cov kab sib txuas thiab txhim kho kev ua haujlwm ntawm cov kab hluav taws xob sib txuas, nws yuav tsum muaj kev nkag siab tob txog kev siv cov insulators. Raws li qhov kev tshuaj xyuas no, peb yuav tsum ua tib zoo txheeb xyuas qhov kev faib tawm ntawm cov khoom siv hluav taws xob hauv cov kab sib txuas, nrog rau cov kev xav tau ntawm cov kab hluav taws xob sib txuas rau cov insulator, thiab txheeb xyuas cov kev ceev faj rau kev siv cov kab hluav taws xob sib txuas, kom ntseeg tau tias lub luag haujlwm ntawm cov insulator hauv cov kab sib txuas tau ua tiav.
1. Mechanical zog
Lub zog txhua yam ntawm lub insulator muaj xws li tensile lub zog, compressive zog, dabtsi yog khoov tsis kam, mechanical impact resistance thiab residual zog, thiab lwm yam. Tsuas yog los ntawm kev ua tau raws li cov saum toj no yooj yim mechanical Performance indicators, As lub insulator ua tau raws li cov kev xav tau ntawm kev ua hauj lwm cov kev xav tau ntawm cov kis kab mob nyob rau hauv lub chaw ua hauj lwm, ua tau raws li cov kev xav tau ntawm kev ruaj ntseg thiab stability ntawm lub kis kab mob, thiab txhim kho tag nrho stability ntawm cov kis kab mob.
2. Kev ua haujlwm hluav taws xob
Kev ua haujlwm hluav taws xob ntawm lub rwb thaiv tsev hais txog tias nws tsis tawg nyob rau hauv qee qhov overvoltage (lub zog zaus voltage, kev khiav hauj lwm overvoltage, xob laim overvoltage) kom ntseeg tau tias kev ua haujlwm zoo ntawm cov kab sib kis. Txij li thaum lub insulator ua haujlwm nyob rau hauv cov kab sib kis, qhov kev ua tau zoo ntawm hluav taws xob yog ib qho tseem ceeb los ntsuas seb lub insulator puas tuaj yeem ua tau raws li qhov xav tau ntawm kev ua haujlwm. Raws li qhov kev txiav txim siab no, kev ua haujlwm hluav taws xob ntawm lub insulator yuav tsum ua kom tau raws li lub hom phiaj ntawm kev tsis raug tawg hauv qhov overvoltage.
3. Thaum tshav kub kub cav kev ua haujlwm
Xav tias qhov kev ua haujlwm ntawm lub insulator yog qhov hnyav, ntxiv rau lub xeev ib txwm muaj, tab sis kuj tuaj yeem tiv taus khov, kub, kub thiab siab siab thiab lwm lub xeev, uas yuav tsum tau lub insulator kom muaj lub zog thermal ua haujlwm, thiaj li ua tau raws li qhov xav tau ntawm kev ua haujlwm ntawm lub insulator.
4. Insulator tiv thaiv kev ua haujlwm tsis zoo
Insulator nyob rau hauv high voltage teb lub zog, mechanical load thiab atmospheric activating lub sij hawm ntev, nws cov hluav taws xob kev ua tau zoo thiab cov neeg kho tshuab nqa muaj peev xwm mus txuas ntxiv poob rau lub sij hawm, thiab maj mam poob rwb thaiv tsev kev ua tau zoo thiab mechanical nqa peev xwm. Yog li ntawd, nws yog ib qho tsim nyog los qhia txog kev tiv thaiv kev ua haujlwm tsis zoo ntawm lub insulator, xyuas kom meej tias kev tiv thaiv kev ua haujlwm tsis zoo ntawm lub insulator ua tau raws li qhov xav tau tiag tiag, ua tiav lub hom phiaj ntawm kev txhim kho kev ua haujlwm ntawm lub insulator, thiab txhim kho kev tiv thaiv kev puas tsuaj ntawm tag nrho cov insulator.
