1. product introduction
ellumi-3 series ring main unit is applied in 10kv distribution system, which can realize ring network power supply and radial power supply. it has the characteristics of small size and compact structure, and can greatly save the floor area of switching station or distribution room. therefore, it is widely used in industrial area, high-rise buildings, large public buildings, residential areas, prosperous commercial centers, outdoor switch boxes, box type substations and other places.
2. product features
◆ it is safe and reliable. the air box body and cable connection room are equipped with fault arc protection design, and the bottom of the air box and cable connection room is equipped with explosion relief film and pressure release device, which can maximize personal safety
◆ the switch cabinet shell is assembled by c-section. the whole shell is divided into instrument room, main bus room, circuit breaker room and cable room. each compartment is separated by metal partition
◆ vs1-12 series vacuum circuit breaker is used as the main switch for closing the cabinet, gn30s-12 or gn22-12 series is used as the isolation switch, and full insulation structure is used for the transformer, so the safety margin of the whole cabinet is high
