Ọdịiche dị n'etiti eriri igwe AC na igwe DC

E nwere ụdị abụọ nke relays electromagnetic: AC na DC. Na ụkpụrụ, mgbe a na-etinye voltaji DC na nsọtụ abụọ nke eriri mmiri ahụ, a na-ekpebi ihe a na-emepụta ugbu a site na nguzogide nke eriri. N'ihi na resistivity nke ọla kọpa dị nnọọ obere, iji hụ na nke ugbu a adịghị oke ibu, eriri igwe ga-mere na mkpa waya dayameta na otutu ntụgharị. N'aka nke ọzọ, eriri igwe AC na-ekpebi ugbu a site na mmeghachi omume, yabụ a ga-eme eriri eriri ahụ na dayameta waya siri ike yana ọnụ ọgụgụ dị nta nke ntụgharị. Ya mere, mgbe a na-eji 24V AC relay na usoro DC 24V, relay ga-ere ọkụ ngwa ngwa n'ihi na nguzogide ezughị oke. Otú ọ dị, mgbe a na-eji relay DC na sistemụ AC, ọ bụ ihe a na-apụghị izere ezere na relay agaghị adọba nke ọma ma ọ bụ enweghị ike ịdọrọ ya n'ihi nnukwu mmeghachi omume ya.

1.Generally, e nwere ụdị abụọ nke relays: AC na DC, na AC ndị na-ukwuu 24VAC, 220VAC na 380VAC. Ihe mkpuchi mkpuchi mkpuchi AC ndị a ga-enwerịrị ogwe mkpuchi, nke dị mfe ikpe ikpe, mana ọtụtụ obere relays AC enweghị ogwe mkpuchi a. Enwere ọtụtụ ọkwa nke voltaji DC, dị ka 6, 12 na 24 volts. Igwe mmiri agbagharị agbagharị na-adịkarị gịrịgịrị ma isi ya enweghị mkpanaka mkpuchi.

2.AC contactors nwere ike dochie DC contactors na ikpe nke mberede, na ịdọrọ-na oge enweghị ike gafere 2 awa (n'ihi na okpomọkụ dissipation nke AC coils dị njọ karịa nke DC, nke kpebisiri ike site na ha dị iche iche owuwu). N'aka nke ọzọ, DC enweghị ike dochie ndị kọntaktị AC.

3.The eriri igwe atụgharị nke AC contactor dị ole na ole, ebe ndị DC contactor dị ọtụtụ, nke nwere ike dị iche na eriri igwe olu.
