Hloov lub txee (tseem hu ua ib qho ua tiav ntawm cov keyboards lossis cov khoom siv hluav taws xob ua tiav): Nws yog cov khoom siv hluav taws xob feem ntau raws li cov khoom siv hluav taws xob; Nws yog hais txog cov chaw tsim khoom tsim cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob (suav nrog cov khoom siv tswj, cov khoom siv tiv thaiv, thiab lwm yam) raws li cov kev xav tau ntawm cov hluav taws xob tseem ceeb ntawm cov kab hluav taws xob. Cov khoom siv hluav taws xob, cov khoom siv ntsuas) nrog rau cov busbars, cov khoom siv tam sim no, cov khoom siv hluav taws xob, thiab lwm yam yog sib sau ua ke hauv cov khoom kaw lossis qhib hlau thiab ua cov khoom siv rau kev txais thiab faib hluav taws xob hauv lub zog hluav taws xob.
ambient kub: Qhov kub ntawm huab cua kub tsis tshaj 40 degree (sab sauv txwv), nyob rau hauv cov cheeb tsam nws yog -5 degree (tso txwv), thiab nyob rau hauv qhov chaw txias heev nws yuav yog -15 degree . Yog hais tias qhov kub thiab txias ambient siab dhau lawm, qhov conductivity ntawm cov hlau yuav txo, qhov kev tiv thaiv yuav nce, thiab oxidation nto yuav intensify; ntawm qhov tod tes, yog tias qhov kub thiab txias siab dhau lawm, lub neej ntawm cov khoom siv insulating hauv lub txee yuav luv heev thiab lub zog rwb thaiv tsev yuav txo qis. Ntawm qhov tsis sib xws, qhov kub thiab txias ambient Yog tias nws qis dhau, kev ntxhov siab sab hauv yuav raug tsim tawm hauv cov khoom siv insulating, uas yuav ua rau muaj kev puas tsuaj ntawm cov khoom insulating.
Qhov siab: feem ntau tsis tshaj 1, 000 meters. Rau cov cuab yeej ntsia ntawm qhov siab siab tshaj 1,000 meters, qhov rwb thaiv tsev theem ntawm cov rwb thaiv tsev sab nraud yuav tsum yog qhov yuav tsum tau rwb thaiv tsev tiv thaiv hluav taws xob sib npaug los ntawm kev kho qhov zoo Ka [ka=1÷(1.{{ 6}}H × 10-4)] txiav txim siab. Txij li cov huab cua nyob rau hauv high-altitude cheeb tsam yog nyias, cov rwb thaiv tsev sab nraud ntawm cov khoom siv hluav taws xob yog qhov ua rau tawg. Yog li ntawd, cov khoom siv hluav taws xob siv hluav taws xob muaj zog yog siv los ua kom cov huab cua rwb thaiv tsev nyob deb, lossis ntxiv kev tiv thaiv kev tiv thaiv hauv lub txee hloov.
Environmental humidity: Tus nqi nruab nrab txhua hnub tsis ntau dua 95%, thiab tus nqi nruab nrab txhua hli tsis ntau dua 90%.
Av qeeg siv: tsis ntau tshaj 8 degrees.
Lwm yam kev mob: Tsis muaj kev pheej hmoo ntawm hluav taws kub, tawg, muaj kuab paug hnyav, tshuaj lom neeg corrosion thiab kev co hnyav.
