Hxgn-12 series AC metal ring network switchgear is a compact and expandable metal closed ring network switchgear suitable for power distribution automation, which uses fln-12 SF6 load switch as the main switch and adopts air insulation for the whole cabinet.
The utility model has the characteristics of simple structure, flexible operation, reliable interlocking, convenient installation, etc. It can provide satisfactory technical solutions for various applications and different user requirements.
The main switch of hxgne-12 series AC metal ring network switchgear is fln36-12 type produced by our company or SFG type SF6 load switch produced by ABB company. It can also be equipped with VS1 type, vd4/s type, ISM type vacuum circuit breaker or hd4/s5 type SF6 circuit breaker according to the needs of users.
The load switch and circuit breaker can be operated manually or electrically. The distribution automation function can be realized after the electric operating mechanism Pt, CT, FTU and communication device are selected.

Hxgn-12 circuit breaker is mainly used for incoming cabinet as main power supply or standby power supply in ring network power supply system and intermediate section cabinet of dual power supply system. The circuit breaker is VS1, vd4/s, ISM vacuum circuit breaker or hd4/s SF6 circuit breaker with slightly different overall dimensions. The circuit breaker cabinet consists of instrument room, bus room, load (isolation) switch room, circuit breaker room and cable room from top to bottom. CT, Pt, lightning arrester, grounding switch and relay protection device can be configured according to the needs of users, with reliable "five prevention" interlocking function.
The operating mechanism of VS1 vacuum circuit breaker is spring energy storage type, which can be operated by AC or DC or manually. It is the largest domestic vacuum circuit breaker in China at present. Its main electric circuit and operating mechanism are designed integrally, with stable quality and reliable performance. Composite insulation of main electric circuit, small volume. Handcart type or fixed type installation can be adopted. Corresponding to 630A rated current specification, the rated short-circuit breaking current reaches 25kA.
Vd4/s vacuum circuit breaker or hd4/s SF6 circuit breaker is specially designed for ring network switchgear by ABB company in Italy. Its starting capacity is sufficient to cope with various states, including the operation of normal switching equipment or branch network and the breaking of short-circuit current under special circumstances. The two types of circuit breakers a, B and C are arranged vertically, easy to install, small in size and light in weight. The rated short-circuit starting current reaches 25kA.
German ism vacuum circuit breaker with permanent magnet mechanism is a high-tech product specially designed for assembling 10kV ring network cabinet, with the latest technical level of high-voltage switch in the 21st century. Its permanent magnet operating mechanism is an electromagnetic device with electronic control, online detection element and permanent magnet holding.
