iintlobo rhoqo amacandelo kuphuhliso lotyando abakhuseli Izikhuseli zotyando zizixhobo ezinciphisa umbane odlulayo. Amacandelo awenza umkhuseli wokuqhafaza ikakhulu abandakanya amacandelo okukhutshwa kwegesi ye-gap (ezifana neetyhubhu ze-ceramic zokukhutshwa kwegesi), amacandelo okukhusela umbane oqinileyo (njengama-varistors), amacandelo okukhusela umbane we-semiconductor (njenge-TVS yokunciphisa i-diode, i-ESD i-multi-pin components) , SCR, njl.). Makhe sazise iintlobo zamacandelo kwimbali yoshishino lokukhusela umbane: 1. Umtya wesithuba esilungisiweyo Umtya we-gap osisigxina yinkqubo elula yokucima i-arc. Iqukethe ezininzi i-electrode zetsimbi zangaphakathi ezigqunywe ngerabha ye-silicone. Kukho imingxuma emincinci phakathi kwe-electrode yangaphakathi, kwaye imingxuma inokunxibelelana nomoya wangaphandle. Le mingxuma emincinci yenza uthotho lwe-Micro Chamber. 2. Umtya we-graphite Iphepha legraphite lenziwe ngegraphite kunye nomxholo wekhabhoni we-99.9%. Iphepha legraphite lineenzuzo ezikhethekileyo ezingenakutshintshwa kwezinye izinto zetsimbi ngokubhekiselele kumbane kunye ne-thermal conductivity. Umsantsa wokukhupha ukhuselwe omnye komnye. Le teknoloji ye-lamination ayisombululi kuphela ingxaki ye-freewheeling, kodwa iphinda ikhuphe umaleko ngomqolo, kwaye imveliso ngokwayo inomthamo onamandla kakhulu wangoku. Izinto eziluncedo: uvavanyo lwangoku lokukhutshwa okukhulu kwe-50KA (ixabiso elilinganisiweyo lokwenene) ukuvuza okuncinci kwangoku, akukho mbane we-freewheeling, ukukhutshwa kwe-arc, ukuzinza okuhle kwe-thermal Izinto ezingalunganga: i-voltage ephezulu eseleyo, ixesha lokuphendula elicothayo. Ewe kunjalo, isekethe encedisayo ye-trigger inokongezwa ukuyiphucula. Njengoko ulwakhiwo lwesibambi sombane lutshintsha, ububanzi bephepha legraphite kunye nokumila kwegraphite kunotshintsho olukhulu. 3. Amacandelo okukhusela umbane we-silicon carbide I-Silicon carbide yimveliso elungisiweyo exelisa iSoviet Union kwiintsuku zokuqala zokusekwa kweRiphabhlikhi yaseChina. Ulwakhiwo lwayo kukucofa kunye nokutywina isithuba kunye neepleyiti ezininzi zevalve yeSiC kumkhono weporcelain wokubamba. Umsebenzi wokukhusela kukusebenzisa iimpawu ezingabonakaliyo ze-SiC valve plate. Ukukhuselwa kombane kuncinci kakhulu, kwaye umbane omkhulu wangoku unokukhutshwa ukukhawulela i-voltage eseleyo. Emva kokuba i-voltage idlulile, ukuchasana kuya kunyuka ngokuzenzekelayo, ukunciphisa i-freewheeling yangoku ukuya kumashumi e-amperes, ukwenzela ukuba i-gap inokucima kwaye iphazamiseke. ISilicon carbide arrester sesona sixhobo sombane sikhusela umbane esinembali ende yokusetyenziswa kwilizwe lam. umsebenzi, umsebenzi wokukhusela umbane awuphelelanga; akukho mandla okhuseleko lwempembelelo yombane eqhubekayo; ukuzinza kweempawu zokusebenza kuhlwempuzekile kwaye kunokubandezeleka ngenxa yeengozi ezidlulayo ze-overvoltage; umthwalo wokusebenza unzima kwaye ubomi benkonzo bufutshane, njl. Ezi ziveze amandla okubambisa i-silicon carbide ukusebenzisa iingozi ezifihliweyo kunye nobuchwepheshe bemveliso umva. 4. Iipilisi zohlobo lwepilisi ezikhuselayo Ulwakhiwo lwalo kukucinezela kunye nokutywina i-gap kunye nezinto ezichasayo (i-shot lead dioxide okanye i-emery) kwi-sleeve ye-porcelain yokubanjwa. Xa i-voltage iqhelekile, i-gap ihlukaniswe kwi-voltage yokusebenza. Xa i-overvoltage yombane iphula i-gap, i-lead dioxide yinto ephantsi yokumelana, ehambelana nokuvuza kombane omkhulu okhoyo emhlabeni ukunciphisa ukugqithisa. I-monoxide ekhokelayo iqulethwe, kwaye i-frequency frequency yangoku ye-freewheeling yangoku iyancitshiswa, ukuze i-gap icinywe kwaye ikhoyo iphazamiseke. Iimpawu ezikhuselayo zesibambi sohlobo lwepilisi azilunganga, kwaye zitshintshwa ngababambi be-silicon carbide kwilizwe lam.
