HXGT6B-12 environmental protection gas insulated metal enclosed ring network switchgear The HXGT6B-12 type ring main unit is the latest high-performance, green and environmentally friendly 12kV intelligent ring main unit developed by Tianan Electric that combines vacuum arc extinguishing and (environmental) gas insulation technology. All high-voltage live components of the product are sealed in a stainless steel box (IP67) filled with lower pressure (0.02～0.04MPa gauge pressure, 20℃) pure nitrogen or compressed dry air, and environmentally friendly gas is used to replace the greenhouse effect SF6 gas does not change the user's operation and maintenance habits of the inflatable ring main unit, and is a perfect substitute for the SF6 ring main unit and solid insulated ring main unit, providing users with new green products. •The rated current of the circuit breaker cabinet can reach 1250A, and the breaking 31.5kA can replace part of the KYN28A-12 central cabinet; •Equipped with three-station isolation switch grounding observation window; •The amount of solid insulation material is small, and the environmental protection is more prominent; •Safe and reliable use under zero gauge pressure conditions; •There are two schemes of upper isolation and lower isolation for users to choose; it can realize the direct closing of the cable-side grounding switch, which conforms to the "five prevention" operating procedures of the electric power department and conforms to the user's usage habits; •Using self-designed and mature circuit breaker/load switch operating mechanism and three-station isolation mechanism, it has strong versatility and reliability.
