Ukuqonda Iqhaza Le-Ring Main Unit (RMU) Ekusabalaliseni Amandla Kwesimanje

Iyini Iyunithi Eyinhloko Yendandatho (RMU)?

ARing Main Unit (RMU)iwumshini wokushintshela ohlangene, ovalwe, futhi ovalwe ngensimbi osetshenziswa ezinhlelweni zokusabalalisa amandla kagesi aphakathi nendawo (MV). 11kV kuya ku-33kV, ama-RMU akha ingxenye ebalulekile yamanethiwekhi okusabalalisa esibili, anika amandla ukunikezwa kwamandla okuqhubekayo ngisho nalapho ingxenye yenethiwekhi ingaphansi kokunakekelwa. shintsha, hlukanisa, futhi uvikele ama-transformer nemigqa yokuphakelayokunethiwekhi yokusabalalisa amandla e-loop noma e-radial.

Izinkambu Zokusebenza zama-RMU

I-Ring Main Units isatshalaliswa kabanzi emikhakheni eyahlukene, okuhlanganisa:

• Ukusatshalaliswa kwamandla emadolobheni: Iqinisekisa amandla athembekile emadolobheni anezinhlelo zamakhebula angaphansi komhlaba.
• Izinsiza zezimboni: Ivikela amanethiwekhi angaphakathi ezimbonini, ezindaweni ezihluzwa uwoyela, nasezimbonini ezicutshungulwayo.
• Amandla avuselelekayo: Ukuxhumana phakathi kwamandla elanga noma omoya kanye negridi yensiza yendawo.
• Amaphrojekthi wengqalasizinda: Itholakala ezikhumulweni zezindiza, kojantshi wesitimela, nezakhiwo eziphakeme.

Amathrendi Emakethe kanye Nenguquko Yezobuchwepheshe

Ngokuvumelana neIEEMAkanye nemibiko yakamuva eyenziwe nguMordor Intelligence, imakethe ye-RMU kulindeleke ukuthi ikhule kakhulu ngo-2030 ngenxa yokukhula kwamadolobha, igridi yesimanje, kanye nokwanda kwamandla avuselelekayo. SF₆ ama-RMU afakwe igesiiphawuleka kakhulu ekuthuthukisweni kokuphepha kwemvelo kanye nokunciphisa imikhondo.

Icaphuna abaholi bemboni:

• I-ABBfuthiI-Schneider Electricbabe ngamaphayona amadizayini we-RMU ahlangene, okunakekela kancane.
• IEEEincoma ukulungiselelwa okusekelwe ku-RMU kumagridi ahlakaniphile ukuze kuthuthukiswe ukuphathwa kwamaphutha nokuthembeka kwenethiwekhi.

Ukucaciswa Okubalulekile Kwezobuchwepheshe (I-12kV RMU evamile)

Ipharamitha	Inani
I-Voltage elinganiselwe	12 kv
Ikalwe okwamanje	630 A
Isilinganiso Somjikelezo Esifushane	21–25 kA
Uhlobo lwe-Insulation	I-SF₆ gas / Solid dielectric
I-Operating Mechanism	Ngezandla noma ngemoto
Ikilasi Lokuvikela	IP54 noma ngaphezulu
Ukuthobela Amazinga	I-IEC 62271-200 / 100 / 103

I-RMU vs Traditional Switchgear

Isici	RMU	I-Switchgear Yendabuko
Usayizi	Ihlangene	I-Bulky
Isondlo	Okuncane	Kudingeka ngezikhathi ezithile
I-Insulation Medium	I-SF₆ noma i-dielectric eqinile	Umoya noma amafutha
Ukuzihlukanisa ngenxa yephutha	Ngokushesha ngokuphazamiseka okuncane	Ngokuvamile idinga ukuvala shaqa ngokuphelele
Umthelela Wezemvelo	Iphansi ngokuhlukahluka kwe-eco-friendly	Okumaphakathi kuya phezulu kuye ngohlobo

Ama-RMU ahlinzeka ngezinzuzo ezibalulekile ezindaweni laphoisikhala silinganiselwefuthiukwethembeka okuphezuluiyadingeka.

Indlela Yokukhetha I-RMU Elungile

Amathiphu Okukhetha:

• Nquma ii-voltage elinganiselwe kanye namanjeokudingekayo.
• Khethauhlobo lwe-insulationngokusekelwe kuzinqubomgomo zemvelo (i-solid dielectric ikhethwa ezindaweni ezizwela i-eco-sensitive).
• Khethaamayunithi e-RMU ajwayelekileuma ukulinganisa okuzayo kulindeleke.
• Qinisekisaukuhambisana okujwayelekile: khetha njalo imikhiqizo evumelana nayoI-IEC 62271-200.

Imikhiqizo Enconyiwe:

• PINEELE,I-ABB,Eaton,Siemens,I-Schneider Electric

Imibuzo Evame Ukubuzwa Mayelana Nezindandatho Eziyinhloko

Isiphetho

IRing Main Unit (RMU)akuyona nje ingxenye ebalulekile yokusatshalaliswa kwamandla esimanje—iwumthombo oyinhloko wamagridi ahlakaniphile, ukuhlanganiswa kwamandla avuselelekayo, kanye nokufakwa kukagesi emadolobheni.

Noma ngabe uthuthukisa inethiwekhi yedolobha, wakha ipulazi lelanga, noma uklama imboni yezimboni, ukukhetha i-RMU efanele kungenza umehlukoukusebenza kahle, ukwethembeka, nokuphepha.
