izinhlobo ezihlala njalo zezingxenye ekuthuthukisweni kwezivikeli zokuhlinza Izivikeli zokuhlinza zingamadivayisi akhawulela ugesi odlulayo. Izingxenye ezakha isivikeli sokuhlinza ikakhulukazi zifaka izingxenye zokukhipha igesi ye-gap (njengamashubhu okukhipha igesi ye-ceramic), izingxenye zokuvikela umbani oqinile (njengama-varistors), izakhi zokuvikela umbani we-semiconductor (njenge-TVS yokucindezela i-diode, izingxenye zamaphini amaningi we-ESD) , SCR, njll.). Ake sethule izinhlobo zezingxenye emlandweni wemboni yokuvikela umbani: 1. Intambo yegebe elungisiwe Intambo yegebe engaguquki iwuhlelo olulula lokucisha i-arc. Iqukethe ama-electrode amaningi ensimbi angaphakathi ambozwe ngerabha ye-silicone. Kunezimbobo ezincane phakathi kwama-electrode angaphakathi, futhi izimbobo zingakwazi ukuxhumana nomoya wangaphandle. Lezi zimbobo ezincane zakha uchungechunge lwe-Micro Chamber. 2. I-Graphite gap string Ishidi le-graphite lenziwe nge-graphite elinokuqukethwe kwekhabhoni okungama-99.9%. Ishidi le-graphite linezinzuzo eziyingqayizivele ezingenakushintshwa ezinye izinto zensimbi ngokuya nge-conductivity kagesi kanye ne-thermal conductivity. Igebe lokukhipha livalekile ukusuka komunye nomunye. Lobu buchwepheshe be-lamination abugcini nje ukuxazulula inkinga ye-freewheeling, kodwa futhi bukhipha ungqimba ngongqimba, futhi umkhiqizo ngokwawo unamandla amanje anamandla kakhulu. Izinzuzo: ukuhlolwa kwamanje kokukhishwa okukhulu kwe-50KA (inani langempela elilinganiselwe) ukuvuza okuncane, akukho mshini we-freewheeling, akukho ukukhishwa kwe-arc, ukuqina okuhle kokushisa Okubi: i-voltage ephezulu eyinsalela, isikhathi sokuphendula kancane. Kunjalo, i-auxiliary trigger circuit ingangezwa ukuyithuthukisa. Njengoba ukwakheka kwesibambi sombani sishintsha, ububanzi beshidi le-graphite kanye nokuma kwe-graphite kunezinguquko ezinkulu. 3. Izingxenye zokuvikela umbani we-silicon carbide I-Silicon carbide iwumkhiqizo oshintshiwe olingisa iSoviet Union ezinsukwini zokuqala zokusungulwa kwePeople's Republic of China. Ukwakheka kwayo ukucindezela nokuvala igebe namapuleti ama-valve e-SiC amaningana kumkhono we-porcelain obophayo. Umsebenzi wokuvikela ukusebenzisa izici ezingaqondile zepuleti le-valve ye-SiC. Ukuvikelwa kombani kuncane kakhulu, futhi inani elikhulu lombani lingakhishwa ukuze kukhawulwe i-voltage esele. Ngemuva kokuthi i-voltage yombani idlule, ukumelana kuzokwanda ngokuzenzakalelayo, kukhawule i-freewheeling yamanje phakathi kwamashumi ama-ampere, ukuze igebe licime futhi liphazamiseke. I-Silicon carbide arrester iyisisetshenziswa sikagesi esivikela umbani esinomlando omude wokusetshenziswa ezweni lami. umsebenzi, umsebenzi wokuvikela umbani awuphelele; awekho amandla okuvikela umbani oqhubekayo; ukuzinza kwezici zokusebenza kuphansi futhi kungase kuhlupheke ngenxa yezingozi zesikhashana zokudlula ngokweqile; umthwalo osebenzayo uyasinda futhi nempilo yesevisi ifushane, njll. Lokhu kuye kwadalula amandla ezibambisi ze-silicon carbide ukuze zisebenzise izingozi ezifihliwe kanye nokuhlehla kobuchwepheshe bomkhiqizo. 4. Izingxenye zokuvikela ukuhlinza zohlobo lwephilisi Isakhiwo sayo siwukucindezela futhi sivale igebe nezinto ezimele (i-shot lead dioxide noma i-emery) kumkhono we-porcelain obophayo. Lapho i-voltage ijwayelekile, igebe lihlukanisiwe ne-voltage yokusebenza. Lapho i-overvoltage yombani idiliza igebe, i-lead dioxide iyinto engazweli kancane, evumela ukuvuza kwenani elikhulu lombani emhlabathini ukuze kuncishiswe ukugcwala ngokweqile. I-monoxide eholayo iqukethwe, futhi i-frequency ye-frequency ye-freewheeling yamanje iyancipha, ukuze igebe licinywe futhi lamanje liphazamiseke. Izici ezivikelayo zesibambi sohlobo lwephilisi azilungile, futhi zithathelwa indawo izibambi ze-silicon carbide ezweni lami.
