Relay osiyanasiyana: cholinga ndi kukula

Difrele ndi difautomats ndi zida zofanana kwambiri. Iwo amasiyana kapangidwe ndi mfundo ntchito. Tiyeni tione mwatsatanetsatane mbali zawo ndi kusiyana kwawo.

Makhalidwe oyambira

Difrel ndi chipangizo chomwe chimateteza ogula kugwedezeka kwamagetsi polumikizana mwachindunji ndi malo opangira magetsi. Mwachitsanzo, waya wosasunthika, zida zamagetsi, zomwe thupi lake limapatsidwa mphamvu.

Relay yosiyana - Zida zofunika kuteteza ku moto pazida zokhala ndi zotchingira zowonongeka komanso mawaya olakwika amagetsi. Ma RCD awa amatsegula chigawochi akapezeka mu wiring ngati kusalinganika komwe kumachitika.

Makampaniwa amapanga mitundu iwiri yosiyana:

• Mtundu wa AC. Ma relay oterowo amapangidwa kuti ayankhe kutayikira kwa sinusoidal alternating mafunde.
• Mtundu A. Wopangidwa kuti aziyika m'mabwalo omwe amadyetsa zida zomwe zili ndi zowongolera kapena ma thyristors momwe zimapangidwira. Ndiko kuti, pakagwa kusweka kwa zotchingira, kutayikira kwanthawi zonse molunjika komanso mosinthasintha kumachitika. Malangizo oyika ma relay oterowo amapezeka mu malangizo ogwiritsira ntchito zida zina zapakhomo.

Kodi difrele ndi yosiyana bwanji ndi difavtomat?

Difrele kapena RCD yokhala ndi automaton yosiyana imakhala ndi zofanana, makamaka zakunja, koma mfundo yogwiritsira ntchito zipangizozi ndizosiyana kwambiri. Kupatsirana kosiyana kumaphatikizapo kuwunika pompopompo vekitala ya zomwe zikuchitika mu gawo - 0.

Ngati kuchuluka kwa ma vectors sikuli ziro, makinawo amalandira chizindikiro kuti atsegule dera, ndiye kuti, amakhudzidwa ndi kutayikira kwamagetsi. Difavtomat imayankha zomwe zimatchedwa kuti overcurrents zomwe zimachitika panthawi yolemetsa komanso yozungulira, ngakhale zina mwazidazi zimayankhanso kutayikira kwapano pansi, kuchita ntchito za automaton ndi relay nthawi yomweyo.

Popeza difrele ndi difautomat ndizofanana kwambiri, zimakhala zovuta kuti katswiri wamagetsi amateur azisiyanitsa - muyenera kudziwa zolembera. Inde, ndi kukhazikitsa zipangizo zomwe zingateteze ku moto ndipo, chifukwa chake, zimatsimikizira chitetezo cha moyo ndi thanzi, ndi bwino kukhulupirira amisiri oyenerera.

Magawo awa amayikidwa pambuyo pa mita yoyambira mugawo lamagetsi panjanji ya DIN yokhazikika. Pamagetsi a 220 V, ali ndi ma terminals awiri pazolowera ndi ziwiri pazotulutsa. M'mabizinesi ang'onoang'ono komanso m'malo omwe ma voliyumu a 380 V amaperekedwa, ma terminals anayi amayikidwa pazolowera ndi kutulutsa. Ma nuances awa ayenera kuganiziridwa kuti agwiritse ntchito bwino zida.
