summary

      The XGN15-12 metal closed loop switch equipment(abbreviated as the sulphur hexafluoride ring) is a new generation of ring mesh cabinet with sulfur hexafluoride load switch as the main switch. The cabinet adopts air insulation, compact and simple structure, flexible operation, and convenient installation., Multiple interlocking function. Equipped with electric mechanism, PT, CT, UPS, RTU, etc. can be widely used in distribution network automation systems. With modern sensing technology and the latest protective relays, its advanced technical performance and lightweight and flexible assembly scheme can fully meet the changing needs of the market.

      The main switch of the cabinet uses domestic FLN 36-12D / T630 -20 or FLN 48-12D / T630 -20 sulfur hexafluoride load switch and ABB's SFG sulfur hexafluoride load switch or Schneider's SC 6 load switch. According to the different components, they can be divided into two types: XGN15-12(F) and XGN15-12(F, R). The XGN15-12(F) cabinet is equipped with a load switch, which is generally used as an incoming line. The XGN15-12(F, R) cabinet is equipped with a load switch and a limited-current fuse combination. The load switch assumes the switching load current. The current overload and short-circuit currents that are relatively large by the current limiting fuse are generally used.

      There are two types of operation: manual and electric.

      The cabinet adopts an imported aluminum zinc sheet processed into a modular structure by a CNC machine tool, and the protection level reaches IP3X, and it has reliable mechanical interlocking and error prevention operation functions.
