Yiliphi iyunithi eliphambili lendandatho (RMU)?
AI-Ring Main Unit (RMU)kuyinto ecwebezelayo, evaliwe, ne-metal-evaliwe yensimbi esetshenziswe ku-Medium-Voltage (MV) Amandla okusabalalisa amandla. I-11kv kuya ku-33kv, I-RMUS yakha ingxenye ebalulekile yamanethiwekhi okusabalalisa wesibili, okwenza amandla okuqhubeka kwamandla okunikezwa ngisho nalapho ingxenye yenethiwekhi ilungiswa. Shintsha, uhlukanise, futhi uvikele ama-transformers kanye nemigqa ye-feederkwinethiwekhi evulekile noma ye-radial kakhu okusatshalaliswa kwamandla.
Izinkambu zohlelo lokusebenza ze-RMUS
Ama-Ring Main Units athunyelwa kabanzi kuyo yonke imikhakha ehlukahlukene, kufaka phakathi:
- Ukusatshalaliswa Kwamandla Amadolobha: Iqinisekisa amandla athembekile emadolobheni ngezinhlelo ezingaphansi komhlaba.
- Izikhungo zezimboni: Vikela amanethiwekhi angaphakathi emafektri, izicoco zokuhlanza uwoyela, kanye nezitshalo zokucubungula.
- Amandla avuselelekayo: Ukuhlangana phakathi kwamandla elanga noma umoya kanye negridi yokusebenza yendawo.
- Amaphrojekthi Wengqalasizinda: Kutholakala kwizikhumulo zezindiza, izitimela kanye nezakhiwo eziphakeme.
Izitayela zemakethe nokuziphendukela kwezobuchwepheshe
Ngokuvumelana neUyemanemibiko yakamuva kaI-Mordor intelligence, Imakethe ye-RMU kulindeleke ukuthi ikhule kakhulu ngo-2030 ngenxa yendawo yokufuduka, ukukhiqizwa kwesimanje, kanye nokunwetshwa kwamandla okuvuselelekayo. I-SF₆ Gas-Inser-Infated RMUSiyaphawuleka ikakhulukazi ngokuphepha okuthuthukile kwezemvelo kanye nokwehliswa kwezinyawo.
Ukushaya Abaholi bezimboni:
- Abisana-Schneider Electricbaphayona compact, imiklamo ye-rmu ephansi ye-RMU.
- IeeeItusa ukucushwa okususelwa ku-RMU kuma-smart grids wokuphathwa kwamaphutha okuthuthukile kanye nokwethembeka kwenethiwekhi.
Ukucaciswa Kwezobuchwepheshe Okusemqoka (okujwayelekile kwe-12kv RMU)

I-RMU vs swindayo yendabuko
| Ubuso | Rmu | I-switchtiva yendabuko |
|---|---|---|
| Ubungako | -Hlangene endaweni encane | -Khulu |
| Ukuhlalisa | -Ncilula | Kudingeka |
| I-Insuration Medium | Sf₆ noma i-dielectric eqinile | Umoya noma uwoyela |
| Ukuzihlukanisa ngenxa yephutha | Ngokushesha nokuphazamiseka okuncane | Kuvame ukudinga ukuvalwa okuphelele |
| Umthelela wezemvelo | Ephansi ngokuhlukahluka okunobungani | Medium to high ngokuya ngohlobo |
I-RMUS ihlinzeka ngezinzuzo ezibalulekile ezindaweni laphoisikhala sinqunyelwena-ukuthembeka okuphezuluiyadingeka.
Ungayikhetha kanjani i-RMU efanele
Izeluleko zokukhetha:
- Nquma i-i-voltage ekalwe futhi yamanjekuyadingeka.
- Qokauhlobo lokufakwaKususelwa kwinqubomgomo yezemvelo (i-dielectric eqinile ekhethelwe ezindaweni ezibucayi ze-eco).
- KhethaAmayunithi we-RMU ajwayelekileUma kulindeleke ukubaluleke ngokwesikhathi esizayo.
- QinisaUkuhambisana okujwayelekile: Khetha njalo imikhiqizo evumelana nayoIEC 62271-200.

Ama-FAQ mayelana namayunithi amakhulu
Ukunikezwa kwe-RMUUkugeleza kwamandla okungaphazanyiswa, noma ngesikhathi sokulungiswa, ngenxa yokucushwa kwayo kwendandatho.
Yebo. IP54 noma ukufakwa okuphezulu, ukuzenza zilungele izimo ezinzima zezemvelo.
I-RMUS ephezulu ye-RMUS evela kubakhiqizi abadumile ngokuvamile inikela a a a a a a aIsikhathi sokuphila seminyaka engama-25 +, ngokulungiswa okuncane.
Ukugcina
Le khasiI-Ring Main Unit (RMU)akuyona nje ingxenye ebalulekile yokusabalalisa kwamandla kwanamuhla - kungumhlinzeki obalulekile wama-grids ahlakaniphile, ukuhlanganiswa kwamandla okuvuselelekayo, kanye nogesi wasemadolobheni.
Ukuthi uthuthukisa inethiwekhi yedolobha, wakhe ipulazi lelanga, noma ukuklama isitshalo sezimboni, ukukhetha i-RMU efanelekile kungenza wonke umehluko ngaphakathiukusebenza kahle, ukuthembeka, nokuphepha.
