ZXGN-12 Series Longitudinal Rotor Fixed AC Metal-enclosed Switchgear
ZXGN-12KV longitudinal rotating fixed AC metal enclosed switchgear (hereinafter referred to as longitudinal rotating fixed cabinet) is a new generation of air insulated switchgear independently developed by our company. Its supporting ZXGV-12KV fixed longitudinal rotating isolation vacuum circuit breaker is also independently developed by our company. It is a new product integrating the functions of isolating switch and vacuum circuit breaker (hereinafter referred to as longitudinal rotating isolation-circuit breaker ". The main circuit of the longitudinal rotating fixed cabinet adopts longitudinal arrangement, and the main primary components are directly connected from top to bottom, so that the main circuit does not need branch bus transition and other insulation supports, the structure is simple and compact, and the opening and closing states of the upper and lower isolation breaks are directly visible. It is a patented product of our company.
When the pole of the vertical rotation isolation-circuit breaker is in the horizontal position, it is in the isolation closing position. When the pole of the rotation isolation-circuit breaker is in the vertical position, it is in the isolation closing position. When in the closing position, the upper contact of the pole is directly plugged into the contact box and the main bus. At the same time, an observation window is reserved on the contact box. Users can configure a display device on the instrument door according to their needs and observe the plug state, you can also directly observe the opening and closing status of the isolation plug from the viewing window on the right side of the lower and middle doors. Compared with similar products, this product has the characteristics of small size, light weight, safety and environmental protection.

Functional composite, convenient operation and maintenance
The main switch ZXGV-12kV the fixed longitudinal rotation isolation-circuit breaker, which is a functional composite circuit breaker integrating vacuum circuit breaker, isolating switch and interlocking. It organically combines the three functions of breaking, isolating and interlocking.
Air insulation, safe and reliable
The circuit breaker rotary pole is used to realize the function of isolating switch, which saves the upper and lower isolating switches, so as to realize the purpose of miniaturization of air insulation. It subverts the traditional method of using insulation coating or using a large number of organic insulating material partitions in the cabinet in order to achieve miniaturization.
Simple circuit, less heat source
The main circuit is connected by the main busbar arranged longitudinally with the contact at the upper end of the pole, the contact at the lower end of the pole is connected with the lower static contact, and the lower static contact is installed on the current transformer.
The entire loop is vertically interconnected from top to bottom, and there is no transition branch bus and insulating support between the components. The conductive path is short, which effectively reduces the source of temperature rise.
Obvious double isolation fracture
Isolation-the rotation of the circuit breaker can be operated manually or electrically. The operator can directly observe the whole process of the insertion and separation of the isolation moving and static contacts through the observation window, and can grasp the isolation state of the circuit breaker in real time.
miniaturization
ZXGN-12.5kV vertical rotary fixed cabinet dimensions: 650mm (wide) X1100mm (deep) X2200mm mm (high), less than other similar air insulation cabinet type.
Intelligent
Longitudinal spin isolation-vacuum circuit breaker can be remotely operated to facilitate rapid isolation of faulty lines and rapid recovery of non-faulty lines. At the same time, it has the functions of real-time online temperature rise monitoring and condition monitoring to meet the requirements of unattended substation and smart grid. -
