Kumahlelo wanamuhla wokusabalalisa kagesi, zombiliI-Ring Main Units (Rmus)aisingeluyizakhi ezibalulekile zokuphatha i-medvol voltage (MV) kanye namanethiwekhi aphansi we-voltage (LV).
Lo mbhalo uhlolaumehluko phakathi kwe-RMUS ne-switchchear, icacisa imigomo yayo yokusebenza, futhi ihlinzeka ngokuqonda ekusetshenzisweni kwayo, amapharamitha wezobuchwepheshe, kanye nenqubo yokukhetha.
Yini i-switchchgear?
IsingeluYigama elibanzi elisetshenziselwe ukuchaza ukushintshwa kokushintshwa kwama-dex switfonnent kagesi, ama-fuse, kanye / noma abaphuluki besekethe asetshenziselwa ukulawula, ukuvikela, nokuhlukanisa imishini kagesi.
Izinhlobo ze-switchgear:
- I-nízkonapěťové rozváděče: Kusetshenziswe ezinhlelweni kuze kube yi-1KV.
- I-Voltage Voltage Voltage: Ngokuvamile kusebenza kusuka ku-1KV kuya ku-36kV.
- Ukucwebela eVysokonkaové Rozváděče: Isebenza kuma-voltages ngenhla kwama-36kv.
Imisebenzi:
- Ivikela amasekethe kagesi ekugcwalisekeni nasemaphutheni.
- Ivumela ukwehlukaniswa nokulawulwa kwezingxenye ezahlukahlukene.
- Igcina ukuphepha ngesikhathi sokulungiswa.
Yiliphi iyunithi eliphambili lendandatho (RMU)?
ARing main unituhlobo lweI-Voltage Voltage VoltageYakhelwe ngqo ukucushwa kwenethiwekhi ye-Loop-Type Network.
Izici ezibalulekile ze-RMUS:
- Amayunithi ahlanganisiwe futhi avaliwe.
- Imvamisa igesi incinisiwe isebenzisaSf₆noma ukufakwa okuqinile.
- Hlanganaukulayisha ukushintshwa kwekhefu,abaphula umjikelezoaukushintshwa kwendlebe.
- YakhelweUkufakwa okulinganiselwe kwedolobha noma kwesikhala.

Izindawo zohlelo lokusebenza
Izicelo eziphambili zeyunithi:
- Amanethiwekhi Okusabalalisa Amadolobha
- Izinhlelo ezingaphansi komhlaba Cable
- Amapulazi Amandla Avuselelekayo (Solar, Wind)
- Izakhiwo zezentengiselwano kanye nezakhiwo eziphakeme
- Ukufakwa kwesibili
Izicelo ze-switchchgear:
- Izikhungo zezimboni ezinemithwalo emikhulu yezimoto
- Okufakwa esikhundleni sokuqala
- Ukusetshenziswa kokusetshenziswa
- Ukukhiqiza izitshalo
- Izikhungo Zokuphehla Amandla
I-RMUS Shine Endaweni Yokusabalalisa Lapho Ukulondolozwa Kwendawo Nokuthembeka Kubaluleke Kakhulu, ngenkathi i-switchgear yendabuko ilungele ukwehluka, ukufakwa ngokwezifiso.
Izitayela Zemakethe Nesendlalelo
Ngokusho kocwaningo lwemakethe kusukaUyemanamaphepha obuchwepheshe onIee xplore, isidingo somhlaba wonke seI-compact, smart, kanye nezixazululo ze-MV eziphansi ze-MVkuyakhula.
- Ukufudumala kwamabanini: Isidingo sama-compact ne-Underground-enobungani be-Units.
- I-Smart Grid Development: I-RMUS isekela i-scada ne-automation.
- Izidingo Zokuthembela: I-RMUS qinisekisa ukuqhubeka kokuhlinzekwa ngokucushwa kwe-loop.
I-switchchear, ngakolunye uhlangothi, iyaqhubeka nokuvela ngezinto ezintshaAbaphuka kakhulu bombuso,Izinzwa ezisuselwa ku-IOTaUkuvikelwa Kwedijithali Kudluliselwa.
