BW-Air-12 Environmental protection gas cabinet
Bwair-12/630t-20 type environmental protection gas insulated metal closed switch vacuum circuit breaker series products, positioning for 12kV primary system of the main loop power supply and distribution equipment, using nitrogen environmental protection gas (dry air or nitrogen) as the main insulat
1. Prevent misoperation and effectively protect personnel and equipment
When the load switch is closed, the isolating switch is automatically closed first; the load switch and the grounding switch also have strict mechanical interlock and electrical interlock. This structure first ensures that the two will not malfunction, that is, when the load switch is closed position, the closing operation of the earthing switch is not possible.
Similarly, when the grounding switch is in the closing position, the closing operation of the load switch cannot be performed; high-quality China BW AIR 12 Environmental Protection Gas Cabinet
Once the front door is opened, the load switch cannot be closed again, which effectively prevents misoperation.
2. High performance indicators. Vacuum and SF6 load switches used in vacuum ring main unit and BW-AIR-12 Environmental Protection Gas Cabinet operate frequently. “Combined minutes” rated active load times up to 100 times, suitable for gas generation and air pressure load switch. It is more than 10 times that of the load switch, and has good breaking capacity. The short-term withstand current is generally 20kA, and the short-circuit current can generally reach 50kA.
3. Easy maintenance. The China BW AIR 12 Environmental Protection Gas Cabinet in the high and low voltage complete set of equipment is generally installed in the power distribution room to avoid the dangers of vehicle collision, personal injury, water immersion, and water ingress in the ring network cable branch box.
Operational impact is minimized. The clear panel design of the cabinet makes the wiring diagram marked on the countertop in the form of a simulation diagram, which is clear at a glance. Some suppliers of BW-AIR-12 Environmental Protection Gas Cabinet also marked the operating instructions and precautions on the counter, further reducing operator errors.
Possibility of operation; most of the equipment produced by BW-AIR-12 Environmental Protection Gas Cabinet suppliers has a charging display device, which can monitor the charging status of the main circuit, not only can indicate the high-voltage charging status, but also can cooperate with the electromagnetic lock to realize the handle The mandatory locking of the door improves the anti-lost performance; a transparent plexiglass observation window is installed on the front door, and the opening and closing status of the load switch can be directly checked.
4. Flexible to use and easy to expand. With the increase of operating experience, the expandable ring network cabinet is gradually replacing the previous fully enclosed ring network cabinet; with the progress of compact design, modular splicing, etc., now the high-quality China BW AIR 12 Environmental Protection Gas Cabinet is very flexible.
As a professional Environmental Protection Gas Cabinet supplier, Bowei Electric can meet the requirements of various design schemes and realize any combination according to the actual needs of customers; the connection method of cable tray is also more flexible, even if the ground is not flat enough, it can also realize Soft connection, no partial discharge; installation of equipment automation interface to prepare for the construction of distribution automation.
Bwair-12/630t-20 environmental protection gas-insulated metal closed switch vacuum circuit breaker series products are located in the main circuit power supply and distribution equipment of 12kV primary system. Air insulation electrical properties;
The product adopts the upper and lower isolation design (the upper isolation vacuum circuit breaker scheme or the lower isolation vacuum circuit breaker scheme) to meet the user’s needs for the upper and lower isolation layout; at the same time, the product cost is reduced.
It is suitable for medium voltage power distribution systems, such as secondary power distribution applications such as ring network power supply, power distribution room, switching station, double radiation power supply, etc.
Product performance conforms to GB3906-2020 “3.6KV-40.5kV AC Gold”
Enclosed switchgear and controlgear.

An SF6 Gas Insulated Ring Main Unit (RMU) is a type of electrical switchgear that uses sulfur hexafluoride (SF6) gas as an insulator. The SF6 gas is contained within a sealed chamber, and the electrical components of the RMU, such as the switchgear and circuit breaker, are also enclosed within this chamber. The use of SF6 gas as an insulator allows for a compact and lightweight design, which makes it ideal for use in restricted spaces and for underground applications.
