mitundu yonse ya zigawo pakukula kwa chitetezo cha opaleshoni Zoteteza ma Surge ndi zida zomwe zimachepetsa kupitilira kwanthawi kochepa. Zigawo zomwe zimapanga chitetezo cha opaleshoni makamaka zimaphatikizirapo zinthu zotulutsa mpweya wa gap (monga machubu otulutsa mpweya wa ceramic), zida zolimba zoteteza mphezi (monga ma varistors), zida zoteteza mphezi za semiconductor (monga kupondereza diode TVS, ESD mapini angapo) SCR, etc.). Tiyeni tiwunikire mitundu yazigawo m'mbiri yamakampani oteteza mphezi: 1. Chingwe chokhazikika chapakati Chingwe chokhazikika cha gap ndi njira yosavuta yozimitsira arc. Amakhala ndi maelekitirodi ambiri amkati achitsulo okutidwa ndi mphira wa silikoni. Pali mabowo ang'onoang'ono pakati pa ma electrode amkati, ndipo mabowo amatha kulankhulana ndi mpweya wakunja. Mabowo ang'onoang'ono awa amapanga gulu la Micro Chamber. 2. Graphite gap chingwe Tsamba la graphite limapangidwa ndi graphite yokhala ndi mpweya wa 99.9%. Mapepala a graphite ali ndi ubwino wapadera umene sungathe kusinthidwa ndi zipangizo zina zachitsulo ponena za kayendedwe ka magetsi ndi kutentha kwa kutentha. Kusiyana kwa kutulutsa kumatsekeredwa kuchokera kwa wina ndi mzake. Ukadaulo wa lamination sumangothetsa vuto la freewheeling, komanso umatulutsa wosanjikiza ndi wosanjikiza, ndipo mankhwalawo ali ndi mphamvu yamphamvu kwambiri. Ubwino: kuyesa kwakukulu kwaposachedwa 50KA (mtengo weniweni woyezedwa) kutayikira kwakung'ono, palibe freewheeling pakali pano, palibe kutulutsa kwa arc, kukhazikika kwamafuta abwino Zoyipa: voteji yotsalira, nthawi yoyankha pang'onopang'ono. Zachidziwikire, gawo lothandizira lothandizira litha kuwonjezeredwa kuti liwonjezeke. Mapangidwe a chomangira mphezi amasintha, kukula kwa pepala la graphite ndi mawonekedwe a graphite kumakhala ndi kusintha kwakukulu. 3. Zida zoteteza mphezi za silicon carbide Silicon carbide ndi chinthu chosinthidwa chomwe chikutsanzira Soviet Union kumayambiriro kwa kukhazikitsidwa kwa People's Republic of China. Kapangidwe kake ndikusindikiza ndi kusindikiza kusiyana ndi ma valve angapo a SiC mu manja a porcelain omangira. Ntchito yachitetezo ndikugwiritsa ntchito mawonekedwe osagwirizana ndi mbale ya SiC valve. Chitetezo cha mphezi ndi chaching'ono kwambiri, ndipo kuchuluka kwa mphezi kumatha kutulutsidwa kuti muchepetse mphamvu yotsalira. Mphamvu ya mphezi ikadutsa, kukana kumangowonjezereka, ndikuchepetsa ma freewheeling pakali pano mkati mwa makumi a amperes, kotero kuti kusiyanako kuzimitsidwa ndikusokonezedwa. Silicon carbide arrester ndiye chida chachikulu chamagetsi choteteza mphezi ndi mbiri yakale yogwiritsidwa ntchito mdziko langa. ntchito, chitetezo cha mphezi sichikwanira; palibe mphezi mosalekeza zikhumbo chitetezo mphamvu; kukhazikika kwa magwiridwe antchito ndi osauka ndipo akhoza kudwala kwakanthawi overvoltage zoopsa; katundu wogwirira ntchito ndi wolemetsa ndipo moyo wautumiki ndi waufupi, ndi zina zotero. Izi zawonetsa kuthekera kwa zomangira za silicon carbide kuti zigwiritse ntchito zoopsa zobisika ndi teknoloji yazinthu zammbuyo. 4. Mapiritsi amtundu wa mapiritsi oteteza zida Kapangidwe kake ndikukanikizira ndi kusindikiza kusiyana ndi zinthu zopinga (kuwombera lead dioxide kapena emery) mumkono wa porcelain womanga. Pamene voteji ndi yachibadwa, kusiyana kumalekanitsidwa ndi magetsi ogwiritsira ntchito. Pamene mphezi overvoltage akuphwanya mpata, kutsogolera dioxide ndi otsika kukaniza mankhwala, amene amathandiza kuti kutayikira kuchuluka kwa mphezi panopa mu nthaka kuchepetsa overvoltage. The lead monoxide lili, ndi mphamvu pafupipafupi freewheeling panopa yafupika, kotero kuti kusiyana kuzimitsidwa ndi panopa anasokonekera. Makhalidwe oteteza amtundu wa mapiritsi si abwino, ndipo amasinthidwa ndi zomangira za silicon carbide m'dziko langa.
