RMU-36/40.5kV

I-RMR-36/40.5kV ivalwe ngokuphelele i-SF6 Gas insulated Switchgear, evamile esiyibiza ngokuthi Ring Main Unit(RMU).
isetshenziselwa ukushintshwa kwegridi kagesi okuphazamisayo okwesibili, Ukuvikela nokulawula.
Iyunithi eyinhloko ye-RMR yohlobo lwe-sf6 ithobelana namazinga e-GB/IEC ejwayelekile IEC62271-200.
Uhlobo lwe-RMR lwamayunithi amakhulu lungahlukaniswa ngezinhlobo ezintathu zekhabhinethi yeyunithi:
- Iyunithi yokuxhuma ikhebula lendawo engu-3 (iyunithi yokushintsha ikhebula), imibukiso eyengeziwe ebukhoma nokucushwa kwezibambisi ezihlinzayo kanye nengxenye yamaphutha aphansi.Ikhodi C
- I-3 position switch kanye ne-fuse tripping system kanye ne- earthing switch interlock fuse iyunithi kagesi ehlanganisiwe (iyunithi yenhlanganisela ye-Fuse), imibukiso eyengeziwe ebukhoma kanye nokucushwa kwezibambisi zokuhlinza kanye nengxenye yephutha eliphansi.Ikhodi F
- Iyunithi yokushintsha indawo engu-3 kanye neyunithi yezinto zikagesi ezihlanganisiwe ze-vacuum circuit breaker (Iyunithi ye-Vacuum circuit breaker), i-transformer yamanje eyengeziwe, imibukiso ebukhoma kanye nokucushwa kwezibambisi zokuhlinza kanye nengxenye yephutha eliphansi.Ikhodi V
Inhlanganisela ye-transformer yamanje kanye nokuvikelwa kwe-microcomputer ukwakha umsebenzi oyisisekelo wokuvikela isekethe.
Ukuvikelwa kwe-Microcomputer kusetshenziswa ukuvikeleka kwe-passive kanye ne-CT kagesi asikho isidingo sereferensi eyengeziwe yokunikezwa kwamandla kagesi we-PT:
I-IEC62271-200
I-IEC62271-100
I-GB3804-2004
I-GB3906-1991
I-GB16926-1997
I-GB/T11022-1999
Phawula:
I-Fuse kagesi ehlanganisiwe ilandela i-IEC 60420
Iyunithi ye-VCB ngokuya nge-IEC 62271-100/GB1984-2003
Indawo yesevisi
a) Izinga lokushisa lomoya: ±40℃;Isilinganiso sansuku zonke ≤25°C
b)Ukuphakama ngaphezu kwezinga lolwandle: Ukuphakama okuphezulu kokuphakama: 4000m
c) Umoya: ngaphansi kwama-35m
d)Amandla okuzamazama komhlaba: angabi ngaphezu kwamadigri ayi-8;
