24kV GPR1 12kV rmu อุปกรณ์จ่ายไฟหลักตู้สวิตช์บอร์ดไฟฟ้าแรงดันสูงและปานกลางสวิตช์เกียร์

GPR1 series gas insulated ring main unit (hereinafter referred to as GPR1 ring main unit) uses SF₆ gas as the insulation medium. SF₆ gas has strong electronegativity, high dielectric strength, and insulation strength 2~3 times that of air. It is non-toxic, odorless, non flammable, and non explosive. It has excellent arc extinguishing and insulation performance, allowing the load switch/circuit breaker to quickly extinguish the arc after breaking the current. Its internal design has a compact structure and small volume, saving space and resources. The gas tank adopts a stainless steel welded fully sealed structure. The operating mechanism adopts a spring type, with a simple structure and flexible operation, and the operating speed is not affected by the size of manpower. The mechanism has complete mechanical locking and reliable interlocking. Adopting modular design, it can be flexibly combined into various distribution schemes to meet the diverse needs of different occasions and users.
