Isiphazamisi sevacuum kwisaphuli sesekethe yombane ophantsi

Isiphazamisi sevacuum, ekwaziwa ngokuba yityhubhu yokutshintsha ivacuum, lelona candelo lingundoqo lokutshintsha kwamandla ombane aphezulu.Umsebenzi ophambili we-vacuum interrupter kukwenza isekethe ephakathi kunye nephezulu yombane inqumle unikezelo lwamandla egumbi lokucima i-arc ye-arc yokucima iqokobhe le-ceramic ngokusebenzisa i-insulation egqwesileyo ye-vacuum ngaphakathi kwityhubhu, enokucima ngokukhawuleza i-arc kunye nokucinezela okwangoku. , ukuze kuphetshwe iingozi neengozi.
Isiphazamisi sevacuum sisebenzisa ivacuum ephezulu ukucima i-arc phakathi kwesibini sabafowunelwa.Njengoko abafowunelwa behamba, umsinga uqukuqela kwindawo encinci.Kukho ukwanda okubukhali kokuchasana phakathi kwabafowunelwa, kwaye iqondo lokushisa kwindawo yokudibanisa landa ngokukhawuleza de kubekho ukuvela kwe-electrode-metal evaporation.Ngelo xesha, intsimi yombane iphezulu kakhulu kwi-gap encinci yoqhagamshelwano.Ukuqhekeka kwesithuba kuvelisa i-vacuum arc.Njengoko i-alternating current iphoqeleka ukuba idlule kwi-zero ngenxa yokumelana ne-arc, kwaye isithuba phakathi koqhagamshelwano olusisigxina kunye noluhambayo luyanda, i-plasma ye-conductive eveliswa yi-arc isuka kude ne-gap kwaye ibe yinto engaqhubekiyo.Umsinga uphazamisekile.

Abafowunelwa be-AMF kunye ne-RMF bane-spiral (okanye i-radial) kwiindawo zokubeka ezisikwe ebusweni babo.Imilo yabafowunelwa ivelisa amandla amagnetic ahambisa indawo ye-arc phezu komphezulu wabafowunelwa, ngoko ke i-arc ayihlali kwindawo enye ixesha elide.I-arc isasazwa ngokulinganayo phezu kwendawo yokudibanisa ukugcina i-voltage ye-arc ephantsi kunye nokunciphisa ukukhukuliseka koqhagamshelwano.
Emva kokuba iindawo ezigqityiweyo zigqityiwe kwaye zicocwe nge-electroplating kunye nokuhlolwa kwe-optical ye-surface consistency yazo zonke iindawo ezizimeleyo zenziwe, isiphazamisi sihlanganiswe.I-solder ye-vacuum ephezulu isetyenziswe kwiindawo ezidibeneyo zamacandelo, iinxalenye zihambelana, kwaye iziphazamisi zilungisiwe.Njengoko ukucoceka ngexesha lokudibanisa kubaluleke kakhulu, yonke imisebenzi yenziwa phantsi kweemeko zegumbi elicocekileyo eline-air-conditioning.Ngale ndlela umenzi unokuqinisekisa umgangatho othe gqolo ophezulu weziphazamisi kunye nemilinganiselo ephezulu enokwenzeka ukuya kuthi ga kwi-100 kA ngokwe-IEC/IEEE 62271-37-013.
