Yeyiphi kwezi ngxaki zilandelayo ekufuneka inikwe ingqwalasela xa usebenzisa ukumelana nokugquma?
I-HV Hipot GD3000B i-Insulation Resistance Tester
Okokuqala, xa uvavanya ukuxhathisa ukugquma kwento yovavanyo, kufuneka sazi umthamo kunye nenqanaba lombane wento yovavanyo, kwaye udibanise idatha yovavanyo kwiminyaka okanye ingxelo yovavanyo lwefektri ukuququzelela ukuthelekiswa kweziphumo zedatha.Ngaphambi kovavanyo, zama ukususa izikhokelo ezifanelekileyo kangangoko kunokwenzeka ukukhupha ngokupheleleyo into evavanyiweyo ukuthintela impembelelo yombane oshiyekileyo kwi-insulation resistance, kwaye usebenzise utywala ukusula ungcoliseko kumphezulu we-wiring into evavanyiweyo ukuthintela ukungcola. ukwanda kokuvuza kwangoku kwaye kukhokelela ekuxhathiseni ukugquma.Xa kuthelekiswa nokumelana nokwenyani kwe-insulation, ubushushu ngexesha lovavanyo yi-18 ~ 26 ℃, kwaye ukufuma malunga ne-70%.Ukuba ubushushu kunye nokufuma kuphezulu kakhulu okanye kuphantsi kakhulu, iziphumo zovavanyo ziya kuchaphazeleka.Khetha amandla ombane afanelekileyo okulinganisa.Ukuba i-voltage iphantsi kakhulu okanye iphezulu kakhulu, iya kuchaphazela idatha.
Xa umphezulu wokuvuza okwangoku ukhulu kakhulu, kuyimfuneko ukwandisa indawo yokukhusela ukukhusela ukuxhatshazwa kwe-insulation.imeko ephantsi.Ngexesha lovavanyo, linda ngaphezu kwe-30S okanye xa inani leedijithi zexabiso lokumelana nokubetha lizinzile ukufunda ixabiso lokumelana.Nangona kunjalo, ngenxa yomthamo ohlukeneyo wento elinganisiweyo, ubude benkqubo ye-DC yokufunxa ngoku kunye ne-polarization nayo yahlukile.Ngokuqhelekileyo, ixesha lokufunda ukuchasana kwe-insulation lihlukile.UGuodian Xigao ucebise ukubhekisa kwimeko yokwenyani kwisiza.Emva kokuba uvavanyo lugqityiwe, isigaba esivavanyiweyo sidinga ukukhutshwa ngokupheleleyo kwakhona, kwaye ixesha lokukhutshwa lide into efuna ukuphinda ihlolwe.I-frequency ye-insulation resistance resistance iphezulu kakhulu ekusebenziseni imihla ngemihla.Akunzima ukuyisebenzisa.Ukuba ukuchasana kwe-insulation akukho ngexesha, unokujonga nganye nganye ngeendlela ezingentla.Ukuba ixabiso lokumelana namanje alivuki emva kokutshekishwa, ngoko kufuneka kuthathelwe ingqalelo ukuba inqanaba le-insulation yovavanyo oluphantsi okanye ukuchithwa kwe-insulation.
