Siyazi ukuba i-relay yoqhagamshelwano kufuneka ibe nenkohlakalo ngaphezu kwe-Mosfet jikelele, umthwalo we-relay mkhulu kakhulu kune-Mosfet.
Umthwalo oqhelekileyo we-DC motor motor, i-DC clutch kunye ne-DC solenoid valves, ezi zitshixo zomthwalo wengqondo zivaliwe, amakhulu okanye amawaka ee-volts zamandla ombane ongemva obangelwa yi-surgery ziya kuqhagamshelana nobomi ukunciphisa okanye zonakaliswe ngokupheleleyo.Ngokuqinisekileyo ukuba i-current incinci, njengaxa kufuphi ne-1a, amandla e-electromotive angasemva aya kubangela ukukhutshwa kokukhutshwa kwe-arc kuya kukhokelela ekudibaneni kokungcola kwee-oxide zetsimbi, okukhokelele ekungaphumeleli koqhagamshelwano, ukuchasana koqhagamshelwano kuba kukhulu.
Apha ukukhankanya, i-relay isoloko isilela, senza ukhuseleko, ikakhulu sifuna ukwandisa ixesha lokusebenzisa i-relay, kuba abafowunelwa bahlala beya kufakwa kwikhabhoni, ukuguga, ubuso bayo bucocekile ekuqaleni.Ukuchasana noqhagamshelwano kuya kwanda ngokukhawuleza xa ubomi be-relay busondele ekupheleni kwe-relay.
Jikelele phantsi kobushushu obuqhelekileyo kunye noxinzelelo, i-air key dielectric breakdown voltage yi-200 ~ 300V.ke injongo yethu ngokubanzi kukulawula amandla ombane angaphantsi kwe-200V okanye amancinci.
I-diode esemgangathweni inokwandisa kakhulu ixesha lokuyeka, i-diode eqhelekileyo kunye ne-zener diode series kwaye ingabi nempembelelo kakhulu kwixesha lokubuyela umva.Ukuba ngumthwalo we-inductive.Xa abafowunelwa behlukene, ixesha elide lokubuyela umva ixesha elide le-arcing, kwaye liya kunciphisa ubomi benkonzo yomfowunelwa.Ngokomzekelo, i-relay exhunywe kwi-diode kwikhoyili idinga ixesha le-9.8ms ukukhulula abafowunelwa.I-zener diode kunye ne-diode encinci yesignali kunye, inokushunqulwa ibe yi-1.9ms.Ikhoyili ayixhunyiwe kwi-diode reverse time relay 1.5ms.
Nangona umthwalo we-inductive unzima ukuwuphatha kunomthwalo ochasayo, ukusetyenziswa kokukhusela okulungileyo kuya kwenza ukusebenza kakuhle.
Kukho iindlela ezimbini ezimbi kakhulu, musa ukuyisebenzisa.
Ngaphantsi komthwalo we-DC, iswitshi ephezulu yokutshintsha inokubangela ukuthotywa okuphezulu okungaqhelekanga (intlantsi yombane).
Xa i-DC solenoid valve okanye i-clutch yolawulo oluphezulu, abafowunelwa banokubakho umhlwa oluhlaza-luhlaza.Izizathu zale meko xa ziveliswa yi-EDM (ukukhutshwa kwe-arc yombane), i-nitrogen kunye ne-oksijini emoyeni kwi-reaction eyenziwe.
Isenzeko sokudluliselwa kwezinto
Xa izinto eziphathekayo zidibene, utshintsho lwenzeka xa inxalenye yoqhagamshelwano iyancibilika okanye yonakaliswe.Ngokudluliselwa kwexesha lokuhamba, kwaye isiganeko siya kubonakala ngezantsi.Emva kwexesha elithile, abafowunelwa abangalinganiyo baya kubambana.
Umthwalo udla ngokubakho kwimijelo emikhulu yangoku (i-capacitive kunye ne-inductive) i-inrush current, i-arc eveliswayo iya kubangela into yokuncamathela.
Ngeendlela ezincangathi kwaye ezimbini kuphela:
Isiphaluka sokukhusela uqhagamshelwano kunye nezinto zokudlulisa izinto ezifana nesilivere, i-tin oxide, i-tungsten yesilivere okanye i-AgCu ekusebenziseni oonxibelelwano.
Ngokuqhelekileyo i-concave shape ibonakala kwi-cathode, i-convex shape ibonakala kwi-anode.
