Test Profile:
Kev ntsuas kub / av noo / tsis tshua muaj siab ntsuas yog siv los txiav txim siab seb cov khoom puas tuaj yeem tiv taus lub peev xwm khaws cia lossis ua haujlwm hauv qhov kub thiab txias / av noo / tsis tshua muaj siab.Xws li kev khaws cia lossis ua haujlwm ntawm qhov siab siab, thauj lossis ua haujlwm hauv cov cua txias lossis tsis muaj cua txias ntawm lub dav hlau, thauj mus rau sab nraud ntawm lub dav hlau, raug rau qhov kub ceev lossis tawg depressurization ib puag ncig, thiab lwm yam.
Cov teeb meem tseem ceeb ntawm huab cua tsis zoo rau cov khoom lag luam yog:
▪ Kev siv lub cev los yog tshuaj lom neeg, xws li cov khoom deformation, kev puas tsuaj los yog tawg, kev hloov ntawm lub cev thiab tshuaj lom neeg cov khoom ntawm cov ntaub ntawv uas tsis tshua muaj siab, txo cov cua kub hloov ua rau cov khoom overheat, sealing tsis ua hauj lwm, thiab lwm yam.
▪ Cov teebmeem hluav taws xob xws li arcing ua rau cov khoom tsis ua haujlwm lossis ua haujlwm tsis ruaj khov.
▪ Kev cuam tshuam ib puag ncig xws li kev hloov pauv hauv cov khoom siv hluav taws xob ntawm cov pa roj tsawg thiab cua ua rau muaj kev hloov pauv hauv kev ua haujlwm thiab kev nyab xeeb ntawm cov qauv kuaj.Thaum tsis muaj atmospheric siab, tshwj xeeb tshaj yog thaum ua ke nrog kub kub, lub dielectric lub zog ntawm cov huab cua yog ho txo, ua rau muaj kev pheej hmoo ntawm arcing, nto los yog corona paug.Kev hloov pauv ntawm cov khoom siv vim qhov kub qis lossis kub siab ua rau muaj kev pheej hmoo ntawm deformation lossis tawg ntawm cov khoom kaw lossis cov khoom siv hauv qab cua tsis tshua muaj siab.
Cov khoom kuaj:
Cov cuab yeej siv dav hlau, cov khoom siv hluav taws xob siab siab, cov khoom siv hluav taws xob lossis lwm yam khoom siv
Cov khoom xeem:
Tsis tshua muaj siab ntsuas, kub siab thiab tsis tshua muaj siab, tsis tshua muaj kub thiab tsis tshua muaj siab, kub / av noo / tsis tshua muaj siab, ceev decompression test, thiab lwm yam.
