Ugqithiso olwahlukileyo: injongo kunye nobubanzi

I-Difrele kunye ne-difautomats zizixhobo ezifanayo kakhulu. Ziyahluke ngokuyila kunye nomgaqo wokusebenza. Makhe siqwalasele ngokubanzi iimpawu zabo kunye nomahluko.

Iimpawu eziphambili

I-difrel sisixhobo esikhusela abathengi kwi-shock yombane xa bedibana ngokuthe ngqo nomphezulu wokuqhuba. Ngokomzekelo, ucingo olungafakwanga, isixhobo sombane, umzimba walo unamandla.

udluliselo olwahlukileyo - Izixhobo eziyimfuneko ukukhusela imililo kwisixhobo esine-insulation eyonakeleyo kunye neentambo zombane ezingalunganga. Ezi RCD zivula isiphaluka xa zivela kwi-wiring ukuba ukungalingani kwangoku kwenzeka.

Ishishini livelisa iindidi ezimbini zedifrele:

• Uhlobo lwe-AC. Ugqithiso olunjalo lwenzelwe ukuphendula ukuvuza kwe-sinusoidal alternating currents.
• Uhlobo A. Yenzelwe ukufakwa kwezo zijikelezo ezondla izixhobo ezine-rectifiers okanye i-thyristors ekubunjweni kwayo. Oko kukuthi, apho, xa kwenzeka ukuchithwa kwe-insulation, ukuvuza kokubili okuthe ngqo kunye nokutshintshana kwangoku kwenzeka. Imiyalelo yokufakela i-relays enjalo ifumaneka kwimiyalelo yokusebenza kwezinye izixhobo zendlu.

Yahluke njani i-difrele kwi-difavtomat?

I-difrele okanye i-RCD ene-automaton eyahlukileyo inezinye izinto ezifanayo, ngakumbi zangaphandle, kodwa umgaqo wokusebenza kwezi zixhobo uhluke kakhulu. I-relay eyahlukileyo ibandakanya uhlalutyo lwe-vector olukhawulezayo lwangoku kwisigaba-0.

Ukuba isamba se-vectors si-non-zero, i-mechanism ifumana isignali yokuvula isiphaluka, oko kukuthi, isabela kwi-leakge yangoku yombane. I-difavtomat iphendula kwizinto ezibizwa ngokuba yi-overcurrents ezenzeka ngexesha lokugqithiswa kunye nesiphaluka esifutshane, nangona ezinye zezi zixhobo ziphinda ziphendule ukuvuza kwangoku emhlabeni, ukwenza imisebenzi ye-automaton kunye ne-relay ngaxeshanye.

Kuba i-difrele kunye ne-difautomat zifana ngokumangalisayo, kunzima kakhulu kwi-amateur electrician ukuzahlula - kufuneka wazi iimpawu. Ewe, kunye nokufakwa kwezixhobo ezinokuthi zikhusele umlilo kwaye, ngenxa yoko, ziqinisekisa ukhuseleko lobomi kunye nempilo, kungcono ukuthembela abachwephesha abaqeqeshiweyo.

Ezi yunithi zifakwe emva kwemitha yentshayelelo kwipaneli yombane kumzila we-DIN osisigxina. Kwi-voltage ye-220 V, banama-terminals amabini kwi-input kunye neebini kwi-output. Kumashishini amashishini kunye nakwiindawo apho i-voltage ye-380 V inikezelwa, ii-terminals ezine zifakwe kwi-input and output. La ma-nuances kufuneka athathelwe ingqalelo ekusebenzeni ngokufanelekileyo kwezixhobo.
