XGN15-12 Box Type Indoor AC High Voltage SF6 Ring Network Switchgear Fixed Metal Enclosed Electrical Switchgear Enclosure
XGN15-12 indoor AC high-voltage sf6 ring network switchgear is a new generation of sf6 load break switch as switch and air insulation for the whole cabinet, suitable for distribution automation, compact and expandable. The closed switchgear has the characteristics of high grade, miniaturization, complete parameters, low price and less maintenance.
This product has a three-station arc extinguishing chamber of “close-open-ground”, equipped with “five-proof” function (to prevent the main switch from opening and closing with load; to prevent from entering the live interval by mistake; to prevent the main switch from wrongly opening and closing; Line; prevent the grounding switch from transmitting electricity at the grounding position), reliable interlocking, high fracture insulation strength, large creepage design, the outlet end is protected by a pressure equalizing cover, special dynamic seal and fixed seal design, plus advanced technical performance and The light and flexible assembly solution can fully meet the ever-changing requirements of the market. It is a new generation of high-voltage switchgear equipped with urban power grids.
This product is suitable for three-phase AC 10KV, 50Hz power system, as industrial and mining enterprises, high-rise buildings, residential quarters, pre-installed substations, etc. For distribution transformers.Load break switch arc extinguishing principle
SF6 gas has good arc-extinguishing performance. In order to quickly extinguish the arc, the switch will generate an arc when the moving and static contacts are just separated during the current-cutting process. It is long and continuously combined with SF6 gas, which is rapidly dissociated and cooled, and extinguished when the current crosses zero. The principle of permanent magnet rotating arc, small operating work, strong arc extinguishing ability, light contact burn, and prolong electrical life.Use environmental conditions
