RMR-36 / 40.5kV rampung terisolasi SF6 Gas terisolasi Switchgear, biasa disebut Ring Unit Utama (RMU).
Iki digunakake kanggo ngoper kothak listrik distrubition sekunder, Proteksi lan kontrol.
Unit utama ring RMR jinis sf6 tundhuk karo standar GB / IEC standar IEC62271-200.
Unit utama ring jinis RMR bisa dipérang dadi telung jinis kabinet unit:
- 3 unit sambungan kabel posisi (unit ngalih kabel), nuduhake urip tambahan lan konfigurasi arresters mundhak lan komponen fault grounding.Kode C
- 3 posisi ngalih lan sistem tripping sekring lan earthing ngalih interlock sistem sekring unit electrical gabungan (Unit kombinasi sekring), nuduhake urip tambahan lan konfigurasi arresters mundhak lan komponen fault grounding.Kode F
- 3 posisi ngalih lan mbobol sirkuit vakum digabungake Unit Perkakas (Unit mbobol sirkuit vakum), trafo saiki tambahan, nuduhake urip lan konfigurasi arresters mundhak lan komponen fault grounding.Kode V
Kombinasi trafo saiki lan proteksi mikrokomputer dadi fungsi perlindungan sirkuit dhasar.
Proteksi mikrokomputer nggunakake proteksi pasif lan CT listrik ora perlu tambahan sumber daya PT standar Referensi:
IEC62271-200
