Enye yezinto ezibalulekileyo zombane zombane wokudibanisa umbane ukuxhatshazwa kwe-insulation, enokuthiwa yi-insulating material phakathi kwekhonkco lombane kunye nenxalenye yoqhagamshelwano.Ukuba ukusebenza kwe-insulation resistance kuphantsi kwinkqubo yokusetyenziswa, kunokubangela ukulahleka komqondiso, kunye nomonakalo omkhulu kwisixhobo.Ezi zilandelayo zeLillutong Lillutong ziya kwazisa inkcazo yomgaqo wokuxhathisa isidibanisi kunye nezinto ezi-6 ezichaphazela isalathiso sokhuseleko!
Inkcazo yomgaqo wokuxhathisa isidibanisi:
Ukumelana ne-insulation kukumelana nokuvuza kwenxalenye yokukhusela phakathi kwekhonkco lombane kunye nendlu yoqhagamshelwano njengoko kuboniswe ngokusetyenziswa kombane.Ukumelana ne-insulation (MΩ) = i-voltage (V) okanye ukuvuza kwangoku kufakwe kwi-insulator.Umsebenzi oyintloko wokuchasana kwe-insulation kukuvavanya ukuba ukusebenza kwe-insulation ye-connector ihlangabezana neemfuno zoyilo lwesekethe kunye neemfuno zeemeko ezifanelekileyo zobuchwepheshe.
Kukho izinto ezininzi ezichaphazela ukhuseleko lwe-insulation ukhuseleko lweziqhagamshelo.Oku kulandelayo kuhlalutywa ngokusekelwe kwizinto ezintandathu: ukufuma, umgama wokutshatyalaliswa kombane, uxinzelelo lomoya oluphantsi, umgangatho wezinto eziphathekayo, umgama wokothuka kombane, kunye nococeko.
1. ukufuma ukuxhathisa isinxibelelanisi ukugquma
Ukonyuka kobumanzi bokumelana ne-insulation kuya kunciphisa i-voltage ye-dielectric, okukhokelela kwizinto ezahlukeneyo ezimbi.
2. Umgama wokutshatyalaliswa kombane wokuxhathisa ukugquma kwekhonkco
Umgama owothukileyo wokuxhathisa ukugquma ubhekisa kowona mgama umfutshane ulinganiswe kumphezulu we-insulator phakathi koqhagamshelwano kunye nomfowunelwa.Ngenxa yokuba umgama womothuko omfutshane wombane unokubangela umphezulu wangoku, imingxunya yofakelo yezikhonkwane kumphezulu webhodi yokufaka i-insulation yezinye izihlanganisi ziyilwe ngamanyathelo econcave kunye neconvex ukunyusa umgama wokothuka kombane kunye nokuphucula ukukwazi ukumelana nomphezulu. ukukhupha.
3. Uxinzelelo oluphantsi lwe-insulation resistance of connector
Xa ukuchasana kwe-insulation kuphezulu emoyeni, i-insulation material iya kukhupha i-gas ukungcolisa uqhagamshelwano, kunye nokwandisa ubushushu obuveliswa ngumbane, okukhokelela ekwehleni kwentsebenzo ye-voltage kunye nephutha le-short-circuit yesekethe.Ke ngoko, izihlanganisi zombane ezingavalwanga ezisetyenziswa kwiindawo eziphakamileyo kufuneka zincitshiswe.Ngokomgangatho wobugcisa wokudibanisa umbane, i-voltage yokumelana ne-1300V phantsi kweemeko eziqhelekileyo, kwaye ukuhla koxinzelelo ngu-200V phantsi kweemeko eziphantsi zoxinzelelo.
4. isinxibelelanisi ukugquma umgangatho wempahla
Umgangatho we-insulation resistance material umisela ukuba ukunyanzeliswa kwe-insulation ye-connector kunokuhlangabezana neemfuno zentsebenzo yombane osele usetwe.
5. Umgama wokutshatyalaliswa kombane wokuxhathisa ukugquma kwekhonkco
Umgama owothukileyo wokuxhathisa ukugquma ubhekisa kowona mgama umfutshane ulinganiswe kumphezulu we-insulator phakathi koqhagamshelwano kunye nomfowunelwa.Ngenxa yokuba umgama womothuko omfutshane wombane unokubangela umphezulu wangoku, imingxunya yofakelo yezikhonkwane kumphezulu webhodi yokufaka i-insulation yezinye izihlanganisi ziyilwe ngamanyathelo econcave kunye neconvex ukunyusa umgama wokothuka kombane kunye nokuphucula ukukwazi ukumelana nomphezulu. ukukhupha.
6. Ucoceko lokumelana nokugquma isiqhagamshelo
Ukucoceka kwangaphakathi kunye nomgangatho wokumelana nokufakwa kwe-insulation kunempembelelo enkulu kwi-dielectric voltage resistance.Emva kovavanyo, i-voltage efunekayo yemveliso yi-1500V, ngelixa i-voltage esetyenzisiweyo kuvavanyo lwangempela yi-400V, okubangela ukuphuka phakathi kwabafowunelwa ababini.Emva kophando, kwafunyaniswa ukuba kukho ukungcola okuxutywe kwi-adhesive, okukhokelela ekuqhekekeni kwe-bonding interface yamacwecwe amabini okufakelwa kwe-insulator kwi-insulator, ngoko ke ukucoceka kokumelana nokukhusela kubaluleke kakhulu.
Emva kokufunda oku ngasentla, ndiyakholelwa ukuba kuya kufuneka uqonde inkcazo yomgaqo wokuxhathisa isinxibelelanisi kunye nezinto ezintandathu ezichaphazela isalathiso sokhuseleko.
