Detail
Product overview
Our company's independently developed and produced YQ-12 inflatable SF6 metal enclosed full insulation series ring main switch cabinet has been listed as a Zhejiang Province science and technology product through type testing by the National High Voltage Electrical Testing Center and the Zhejiang Province Science and Technology Project. Widely used in 20kV/10kV/6kV distribution systems, it is a switch product for various urban and rural users' power transformation and distribution systems. The switch is in modular unit mode and can be combined according to different purposes, including fixed unit combinations and expandable units, to meet the flexible use needs of various substations for compact switchgear.
The Y0-12 inflatable ring main unit is a completely sealed system, with all live parts and switches enclosed in a stainless steel casing. The entire switch device is not affected by external environmental conditions, ensuring operational reliability and personal safety, and achieving maintenance free operation. By selecting expandable busbars, any combination can be achieved to achieve full modularity. The expansion of busbar safety insulation and shielding ensures high reliability and safety. The YO 12 inflatable ring main unit can also provide a TV based automation solution, forming an intelligent switch concept and minimizing on-site installation and debugging workload.
Product features and structure
Safe fully insulated and fully sealed design
The YOKou-12 inflatable SF6 metal enclosed fully insulated series ring main switch cabinet is equipped with a sealed stainless steel box for the main components of the primary circuit, and a low-pressure SF6 annual body is filled inside as the insulation medium. The incoming and outgoing ends can be connected by cable plugs to ensure full insulation and sealing of the ring main cabinet, which is not affected by the external environment. The protection level of the gas box reaches IP67, and the external components of the gas box are specially designed and surface treated to have anti condensation and short-term anti flood functions.
Modular design
Typical unit modules include load switch unit C, load switch fuse combination unit F, circuit breaker unit V, busbar PT unit P, cable feeder unit B, and metering unit M. Different unit modules can be combined arbitrarily to form a common box type inflatable cabinet.
Flexible and scalable design
The YOKou-12 inflatable SF6 metal enclosed fully insulated series ring main switchgear can be combined with various standard modules to form a common box type non expandable ring main switchgear, or different module combinations can be designed as expandable units. Through dedicated busbar connectors, diversified unit combinations can be achieved to maximize the satisfaction of complex and diverse power supply and distribution design schemes in various parts of China.
Specialized branch box application solution
According to the domestic market demand, the busbar of YQ-12 inflatable SF6 metal enclosed fully insulated series ring main switch cabinet can be equipped with left and right outlet sleeves, which is particularly suitable for various cable branch boxes with one or more load switches, achieving flexible and economical distribution solutions.
