Iimpawu zeMechanical parameters (Itheyibhile - 2)

Indlela yokusebenza

Le mveliso igcina amandla ombane, ukuvulwa kombane kunye nokuvala, kwaye ikwanayo nokugcinwa kwamandla ombane, ukuvulwa kunye nokuvala ngesandla, ukukhuselwa kwangoku, isakhiwo sonke siqulathe ukuvala intwasahlobo, inkqubo yokugcina amandla, ukukhutshwa kwangoku, ukuvula nokuvala ikhoyili. , Ukuvula nokuvalwa kwencwadi yokuFunda, ukutshintshwa kokuncedisa kunye nesalathiso sokugcina amandla kunye namanye amacandelo.

Umgaqo-siseko

Inkqubo yokugcina amandla.

Tsala umsesane wokutsala amandla wesandla, okanye unike isixhobo, isiginali yokugcina amandla ombane, imoto iqhuba ingalo yokugcina amandla ukugcina amandla kwindawo yokugcina amandla, kwaye ugcine la mandla ngokusebenzisa iluphu yokugcina amandla.

Inkqubo yokuvala.

Xa uvala i-breaker circuit, ukutsala ikhonkco lokuvala i-manual okanye ukunika umqondiso wokuvala umbane kumatshini, i-spring spring yokuvala ikhutshwa, i-shaft ephumayo yomatshini ijikeleza, kwaye uqhagamshelwano oluhambayo lokuphazamisa luhanjiswe phezulu ngengalo ye-inflection. kunye nepleyiti yokudibanisa yokuqhuba ukudibanisa uqhagamshelwano olusisigxina kunye nokubonelela ngoxinzelelo loqhagamshelwano, ngelixa ugcina amandla entwasahlobo eqhekezayo kunye nokugcina i-breaker circuit kwindawo evaliweyo ngokusebenzisa i-buckling eqhelekileyo yokuvala i-loop yokubamba umatshini.

Inkqubo yokuqhawula.

Xa i-breaker yesiphaluka iphukile, i-ring manual breakout of the mechanism itsalwa okanye isignali yokuqhawula umbane inikwe umatshini, kwaye ukuvala ukuvala umatshini kuvuliwe. Imeko yokuqhawula igcinwe yi-switch breaking spring.

Inkqubo yokhuseleko lwangoku.

Xa i-current equkuqela kwisekethe ephambili ye-interrupter idlula umlinganiselo we-interrupter, imveliso yangoku ukusuka kwicala lesibini le-interrupter iya kubonisa umlawuli, kwaye umlawuli uya kunika i-voltage yokusebenza kwi-coil eqhekezayo, ebangela ukuba isiphazamisi siphume. ikhefu.

Imiyalelo yezibane ze-LED ezinombala oqaqambileyo

Qaphela: Ubume bokusebenza bomlawuli bunokumiselwa ngokuqwalasela izikhombisi zombala ezahlukeneyo kunye nokucima phantsi komlawuli, kunye nelogi yesiganeko se-SOE sinokufumaneka ngepaneli ye-LCD.

Lawula unikezelo lwamandla kunye nokuvula kunye nokuvala ulawulo lombane

Ukunikezelwa kwamandla umlawuli we-BKM600-FDR uvela kwi-high-voltage transformer, i-voltage elinganisiweyo yokunikezelwa kwamandla yi-AC220V, i-50HZ, emva kokuba iplagi ye-aviation yonikezelo lwamandla ixhunyiwe, umlawuli ungena ngokuzenzekelayo kwisimo sokusebenza, kunye nomlawuli. ine-fuse eyakhelweyo kwi-2A-6A.
Ukutshintshela kwikholomu Imoto yokugcina amandla inikwe amandla yi-PT yombane, edityaniswe kwi-column switch emva kokudlula kumlawuli.
Umlawuli we-BKM600-FDR une-capacitor yayo yangaphakathi yokugcina amandla, kwaye ukuvula nokuvala amandla avela kule capacitor. Ukuze uthintele impembelelo yokuguquguquka kwamandla ombane ekuvuleni nasekuvaleni ukusebenza, ukuvulwa kunye nokuvala umbane ophumayo wolawulo lwesekethe yi-DC220V DC yombane. Xa i-voltage yesiphaluka ihla ngokukhawuleza, i-capacitor inokubonelela ngexesha elingekho ngaphantsi kwe-8S ukugcina umsebenzi womlawuli we-BKM600-FDR kunye nokukhululwa kanye.
Qaphela: Umlawuli we-BKM600-FDR wamkela indlela yokuhlawula i-voltage-stabilizing yokuqinisekisa ukuba i-capacitor yokugcina amandla ijikeleze i-DC220V, kwaye ixesha lokutshaja le-capacitor lingaphantsi kwe-0.5S.
