Ukudluliselwa okuhlukile: inhloso kanye nobubanzi

I-Difrele nama-difautomats angamadivayisi afana kakhulu. Zihlukene ngomklamo kanye nesimiso sokusebenza. Ake sicabangele ngokuningiliziwe izici zabo kanye nokwehluka.

Izici eziyisisekelo

I-difrel iyisisetshenziswa esivikela abathengi ekushayweni kukagesi lapho bethintana ngqo nendawo yokuqhuba. Isibonelo, i-wire unnsulated, i-apparatus kagesi, umzimba wayo onikwe amandla.

Ukudluliselwa okuhlukile - Amadivayisi adingekayo ukuze avikeleke emlilweni emishinini ene-insulation eyonakele kanye nezintambo zikagesi ezinephutha. Lawa ma-RCD avula isifunda lapho esenzeka ku-wiring uma kwenzeka ukungalingani kwamanje.

Imboni ikhiqiza izinhlobo ezimbili ze-difrele:

• Uhlobo lwe-AC. Ukudluliselwa okunjalo kuklanyelwe ukuphendula ukuvuza kwamaza ashintshashintshayo e-sinusoidal.
• Uhlobo A. Idizayinelwe ukufakwa kulawo masekhethi aphakela okokusebenza okunezinto zokulungisa kabusha noma i-thyristors ekubunjweni kwayo. Okusho ukuthi, lapho, uma kwenzeka ukuhlukaniswa kwe-insulation, ukuvuza kokubili okuqondile nokushintshayo kwenzeka. Imiyalo yokufaka ama-relay anjalo itholakala emiyalweni yokusebenza yezinye izinto zikagesi zasendlini.

Ihluke kanjani i-difrele ku-difavtomat?

I-difrele noma i-RCD ene-automaton ehlukile inokufana okuthile, ikakhulukazi kwangaphandle, kodwa isimiso sokusebenza kwalawa madivaysi sihluke kakhulu. I-relay ehlukile ihilela ukuhlaziywa kwevekhtha yamanje yesigaba - 0.

Uma isamba se-vectors singeyena u-zero, umshini uthola isignali yokuvula isifunda, okungukuthi, isabela ekuvuzeni kwamanje kagesi. I-difavtomat iphendula kulokho okubizwa ngokuthi ama-overcurrents okwenzeka ngesikhathi sokulayisha ngokweqile nokujikeleza okufushane, nakuba amanye alawa madivayisi aphinde aphendule ekuvuzeni kwamanje emhlabathini, enza imisebenzi ye-automaton kanye ne-relay ngesikhathi esifanayo.

Njengoba i-difrele ne-difautomat ifana ngendlela emangalisayo, kunzima kakhulu kumuntu osebenza ngogesi oyimfundamakhwela ukuwahlukanisa - udinga ukwazi izimpawu. Yebo, nokufakwa kwamadivayisi angavikela emlilweni futhi, ngenxa yalokho, aqinisekise ukuphepha kokuphila nempilo, kungcono ukwethemba izingcweti eziqeqeshiwe.

Lawa mayunithi akhwezwa ngemva kwemitha yesethulo kuphaneli kagesi kumzila wesitimela we-DIN ongashintshi. Ku-voltage engu-220 V, banamatheminali amabili kokokufaka futhi amabili ekuphumeni. Emabhizinisini ezimboni nasezindaweni lapho kunikezwa khona i-voltage engu-380 V, kufakwa amatheminali amane ekufakweni nasekuphumeni. Lawa ma-nuances kufanele acatshangelwe ekusebenzeni kahle kwamadivayisi.
