Q1: What is the purpose of using a Ring Main Unit in power distribution?

A1: The RMU ensures uninterrupted power by allowing looped connections. Even if one feeder fails, the other keeps supplying electricity.

Q2: Is SF₆ gas in RMUs harmful to the environment?

A2: SF₆ is a potent greenhouse gas, but RMUs are sealed and designed to prevent leakage. Modern alternatives include solid-insulated RMUs to reduce environmental impact.

Q3: Can RMUs be used in smart grid systems?

A3: Yes, many RMUs support SCADA integration, remote switching, and real-time monitoring, making them suitable for automated and intelligent grid systems.

Enhliziyweni ye-RMUumtshinga그리고abaphula umjikelezoefakwe ngaphakathiigesi-incisiwenomaKufakwe umoyaokufakiwe. I-SF₆ gesi Ukufakwa kwegesingamandla ayo aphezulu we-dielectric kanye nosayizi ohlangene.

Izinto ezibalulekile zokusebenza:

Ukulayisha ukushintshwa kwekhefu: Phazamisa i-waw waw ngaphansi komthwalo.
회로 차단기: Vikela ngokumelene nemibuthano emifushane nokugcwala ngokweqile.
Ukushintshwa kwendlebe: Imigqa ephephile emhlabathini.
Ama-isolators: Ukuqonda izingxenye zesekethe zesekethe zokulungiswa.

Izinkambu zohlelo lokusebenza

I-Ring Main Units isetshenziswa kabanzi ku:

Amanethiwekhi kagesi wokusabalalisa ka-Urban
Izinhlelo zamandla avuselelekayo (umoya, ilanga)
Izikhungo zezimboni
Izibhedlela, izitolo ezinkulu, kanye nezakhiwo zezentengiselwano
Izinhlelo ezingaphansi komhlaba Cable

Umhlahlandlela wokukhetha kanye nokuthenga

Lapho ukhetha i-RMU, cabanga ngokulandelayo:

Izilinganiso ze-Voltage nezamanje
Uhlobo Lokufakwa (SF₆, okuqinile, noma umoya)
Inani lama-feeders adingekayo
Inqubo yokuvikelwa (fuse noma umpheki wesifunda)
Imvelo yokufaka (i-Indoor noma yangaphandle)
Izidingo Zokulawula Okukude (zokuhambisana kwegridi ehlakaniphile)

Abakhiqizi abaphezulu bafakaAbisa,슈나이더 일렉트릭,Nokia, futhiIdlina, enikeza uhla olubanzi lwezixazululo ze-RMU ezilungisekayo.
