Me ne galvanic kadaici?

Sau da yawa sosai a cikin wutar lantarki na'urorin shi wajibi ne don kawar da wutar lantarki tsakanin high ƙarfin lantarki iko da low irin ƙarfin lantarki iko haihuwarka. A wasu kalmomin, shi wajibi ne don tsayar da kariya na low irin ƙarfin lantarki ikon haihuwarka daga irin ƙarfin lantarki na ɗari ɗari, da ma dubban volts. A zahiri wannan na nufin cewa a cikin wani da aka ba tsarin ko lantarki na'urar zama dole don kawar da halin yanzu da kwarara a kan shared haihuwarka. Rashin halin yanzu ya nuna kasancewar wani babban ohmic juriya tsakanin kowa wayoyi na biyu da na'urorin, wanda yake daidai sarkar scission. Wannan matsala ne warware kadaici - a na'urar m-galvanic hada guda biyu tsakanin lantarki na'urorin.

Tunanin wani talakawa masana'antu da wutar lantarki motor. A cikin mahallin na samar da mafi yawan engine yana da wani aiki da samar da irin ƙarfin lantarki ya fi 200V, wanda shi ne hadarin gaske ga ma'aikata. Saboda haka, da wadata da irin ƙarfin lantarki da windings, Ina nufin canza engine aka sanya ta wajen ƙarin na'urorin, a ikon sharuddan sauyawa kewaye. A daya hannun, da sauya dole ne ma a sarrafawa, misali, a button, da kuma a cikin wannan galvanic kadaici kare sadarwarka daga bugawa m voltages.

By kansu, ya sauya sheka na'urorin kamar contactors da starters ne na'urorin a cikin abin da zane gusar lantarki lamba tsakanin shigar da (Pin electromagnet nada) da kuma fitarwa (ikon lamba kungiyar Starter). Communication therebetween aka yi kawai ta hanyar inji hulda da Magnetic filin da tsarin abubuwa na actuator, inda babban ƙarfin lantarki motor wadata kuskure kula da panel.

Akwai sauran bambance-bambancen karatu da fasaha bayani daga galvanic kadaici. Wannan musamman gidajen wuta. Tare da su taimako shi ne mai sauki shirya galvanic kadaici da ikon wadata. Musamman da tartsatsi amfani da wannan hanya a Electroradio m dalilai. Gaskiyar cewa da ikon samar da nema shi ne kawo hadari ga mutane. Alal misali, in babu lantarki kadaici tsakanin mains da kuma mabukaci katin sarrafa a talabijin sigina, wani rai barazana m zai zama a kan dukkan karfe abubuwa TV zane, da kuma damar yin amfani da "talabijin viscera" cikakken m gida "diy". Batun kariya daga wani lantarki ƙarfin lantarki na wadannan na'urorin mai sauki ne: mashiga ruwa na cikin gida da nema aka sanya tsakanin gidan wuta da mains. Its farko Winding kunshe a cikin cibiyar sadarwa, da kuma kai da sakandare halin yanzu jawo a cikinta har TV iko. Ga ma ta bayyana daya daga cikin amfani fasali na gidan wuta - yana gane da taimako na galvanic kadaici na analog sigina, wanda aka yadu a yi amfani da daban-daban na'urorin.

Tare da ci gaban ikon semiconductor na'urorin da ake amfani da yadu ya sauya sheka na'urorin - optotiristors - a photocoupler (haske) iko tashar. Input (iko) photocoupler kewaye hada da wani kwan fitila ko LED, wanda aka kuzari a lokacin da wani iko alama. A luminous juyi ya kai photosensitive iko lantarki na thyristor, wanda qunshi wani ikon kewaye da anode-cathode. Wannan na samar 100% babu galvanic dangane da shigar-fitarwa. Wani embodiment optocoupler na'urorin ne photon-guda biyu transistor, wanda aka saukin warware galvanic kadaici da analog sigina, misali, a cikin na'urori masu auna sigina aunawa na'urorin.

A amfani da galvanic interchanges a fasahar yana da mafi girma da kewayon ayyuka fiye da rufe a wannan labarin. Fasahar zamani suna kullum cika jerin na'urorin ga aikin injiniya aikace-aikace.
