1, Introduction
The RAG - 12 type AC metal enclosed switchgear (hereinafter referred to as the Switchgears), RAG 12 (B) type AC metal enclosed switchgear (hereinafter referred to as the circuit breaker Switchgears), RAG 12 (F) type AC metal enclosed switchgear(hereinafter referred to Load Break Switch Switchgears), RAG 12 (R) type AC metal enclosed switchgear(hereinafter referred to as the Outgoing Switchgears) is produced by low pressure SF6 Gas to insulate and breaking the three-phase, 50Hz, AC Indoor Distribution Equipments.

The switchgear can be divided into one to five units of Integrated Gas compartment, Circuit Breaker Switchgear is composed of circuit breaker + disconnector, which it is equipped with vacuum circuit breaker and three position of disconnector. It uses the circuit breaker to control circuit, open and close the load and overload current, short circuit current. It uses the disconnector to provide reliable isolating distance for line side cable, when disconnector is in the grounding position that can make the line to be side grounding. Load breaker switch+current-limiting fuse, which it uses load break switch to control circuit, open and close load current, overload current, using the load switch + current-limiting fuse to control, open and close, insulate transformer and other distribution and transmission circuit, and also protect MV side transformers, and short circuit current and overload current of LV distribution circuit. According to primary system diagram, the RAG - 12 (B) , RAG - 12 (F) RAG - 12 (R) are combined to use for Ring network circuit, circuit breaker switchgear, load break switch switchgear, outgoing load break switch switchgear can also be used separately, they are used for 12kvV and below Secondary distribution system, are suitable for 12kV power supply line Ring or dual radiation, when a section of line failure occurs, the line after restructuring to cause fault section isolate fault segment, so as to restore the line power supply in time, that improve power supply to be reliability and utilization. It is suitable for cable feeder network of commercial and industrial area or high load of power supply in rural township high density area. Use safety, less affected by the climate, easy installation, maintenance, saving place, and it is very suitable for the in box-type substation. RAG - 12 series of SF6 Gas-insulated Switchgear is a new generation small size modular switchgear, each module has independent and complete function, it can be combined them in accordance with different design scheme, it is suitable for 12kV MV Distribution system.
