Ring main unit umsebenzinqubo

I-Ring Main Unit Guide ekhombisa i-Circuit Breaker, ama-Isolators, kanye nezindawo zokushintshana. "

I-Ring Main Units (Rmus) iyingxenye ebalulekile yamanethiwekhi okusabalalisa amandla aphakathi nendawo, ukuqinisekisa ukuthembeka, ukuphepha, kanye nokuqhubeka kokuhlinzekwa kukagesi.

Yiliphi iyunithi eliphambili lendandatho (RMU)?

I-Ring Main Unit iyiyunithi ye-Switchgear evunyelwe, evaliwe esetshenziswa kumanethiwekhi okusatshalaliswa kwamandla aphakathi nendawo.

Izici ezibalulekile:

• Isilinganiso se-voltage esiphakathi (ngokujwayelekile i-11KV kuya ku-33kv)
• Kufakwe ensimbi ukuze kuphephe nokuqina
• Kubandakanya ukushintshwa kwekhefu lokulayisha, abaphula umjikelezo kanye nama-fuse

Ukusebenza komgomo weyunithi enkulu yendandatho

Enhliziyweni ye-RMU yi- "Ring" yabaqhubi, okuvumela ugesi ukuthi ugeleze ezindleleni eziningi.

Izakhi ezijwayelekile zifaka:

• Ukulayisha Ukushintshwa Kwekhefu (LBS):Vimbela umthwalo ojwayelekile wamanje
• Abaphula umjikelezo we-Vacuum (VCB):Vikela izijikelezo ezivela kuma-Faliels Custom
• Ukushintshwa kwendlebe:Qinisekisa ukuphepha ngesikhathi sokulungiswa
• Amabhasi kanye nama-isolators:Lungiselela ukujikeleza nokuxhumeka

Izinyathelo Zokusebenza:

1. Amandla ageleza ngokusebenzisa ngakolunye uhlangothi lwendandatho.
2. I-LBS ivumela ukushintshwa okuphephile ngaphansi kwezimo zomthwalo.
3. Uma kutholwa iphutha, i-VCB ihlukanisa isigaba esithintekile.
4. AmaCrews amaqembu wesondlo angasebenza ngokuphepha esigabeni esinikelwe i-de-enikeln ngaphandle kokuphazamisa insiza kwenye indawo.

Izinkambu zohlelo lokusebenza

Ama-ring main amayunithi asetshenziswa kabanzi kuzo zonke izimboni ngenxa yokuphepha kwawo, ukuhlanganiswa kanye nokusebenza kahle.

• Amagridi okusatshalaliswa kwamandla e-Urban
• Izindawo zezimboni nezitshalo zokukhiqiza
• Ukuhlanganiswa kwamandla okuvuselelekayo (amapulazi womoya / elanga)
• Izibhedlela, izikhungo zedatha, nezikhumulo zezindiza

Izitayela Zemakethe Nezimboni

Ngokusho kombiko ka-Ieee ne-IEema, isidingo se-RMUS siyakhuphuka ngenxa yokushiswa kwabantu emadolobheni, isimo se-grid, kanye nokuhlanganiswa okuvuselelekayo.

Abakhiqizi abaphawuleka:

• Abisa: Inikeza i-SF6-insured and eco-esebenza kahle rmus
• Schneider Electric: Kwaziwa ngochungechunge lwabo lwe-SM6 neRingmaster
• Nokia: Ihambisa i-RMUS ngamakhono okuqapha edijithali

Ukucaciswa kobuchwepheshe (amanani ajwayelekile)

Ipharameter	Thanda
Amandla kagesi	I-11kv / 22kv / 33kv
Kukalwe manje	Kufika ku-630A
Isilinganiso sokujikeleza esifushane	Kufika ku-21ka
Uhlobo lokufakwa	I-SF6 noma i-SOOL
Indlela Yokusebenza	Ngesandla / ehamba ngemoto
Ukuvikela	I-Overcurent, Iphutha Lomhlaba
Uhlobo lokufaka	Ngaphakathi / ngaphandle

Ihluke kanjani ama-RMUs kwamanye ama-switchchear

Ngenkathi i-RMUS iwela ngaphansi kwesigaba se-switchchear ebanzi, sabousayizi ohlangene,I-topology esekwe kwindandatho, futhiUkwakhiwa Okungabekezeleleki KokubiZihlukanise.

Ubuso	Rmu	I-switchgear evamile
Ukusongoza icebo	I-compact, amayunithi avaliwe	Kukhulu, modular
Ukuphinda	Ring topology	I-radial / eyodwa indlela
Ukuhlalisa	Okuncane, okuvalwe ngempilo	Ukuhlolwa okujwayelekile kuyadingeka
Isicelo	Amanethiwekhi Okusabalalisa	Okufakwa esikhundleni sokuqala

Amathiphu wokukhetha kanye nokuthenga

Lapho ukhetha i-RMU, cabanga ngalokhu:

• Izilinganiso zeVoltage & yamanjeukufanisa inethiwekhi yakho
• Uhlobo lokufakelwa(Sf6 vs. solid)
• Ukwesekwa okuzenzakalelayoUkulawula okukude nokuhlanganiswa kwe-scada
• Idumela lomkhiqizinenethiwekhi yensizakalo

Hlala uthintana nonjiniyela kagesi oqinisekisiwe noma umhlinzeki wakho wendawo.

Amazolumbo

Ukuqonda umgomo osebenzayo wama-ring amayunithi ama-main amayunithi kubalulekile kochwepheshe ababambe iqhaza ekuhleleni kohlelo lwamandla nokusebenza.

Ngokuqonda okujulile, thinta izinsizakusebenza kusukaIeee,Wikipedia, kanye nemibhalo esemthethweni yomkhiqizo evela ku-ABB, Schneider, noma i-Nokia.
