ZXYN-40.5kV Longitudinal Rotor Removal Type Armored Indoor AC Metal Enclosed Switchgear
ZXYN-40.5KV longitudinal rotary movable armored indoor AC metal enclosed switchgear (hereinafter referred to as longitudinal rotary central cabinet) is a new generation of air insulated switchgear independently developed by our company. Its supporting longitudinal rotary 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 rotary isolation-circuit breaker). The main circuit of the vertical rotary cabinet adopts vertical 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 and closing position. When the pole of the rotation isolation-circuit breaker is in the vertical position, the upper contact of the pole is directly plugged into the contact box and the main bus in the closing position. At the same time, an observation window is reserved on the contact box. Users can configure a display device on the instrument door as required to observe the plug state in the contact box, 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. If you want to repair and replace the circuit breaker, you only need to pull out the longitudinal rotation isolation-the circuit breaker, and the switch replacement can be completed in a short time, saving maintenance cost and time, and using air insulation, which meets the requirements of environmental protection. 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 ZXYV-40.5KV longitudinal rotation isolation-circuit breaker is a functional composite circuit breaker integrating vacuum circuit breaker, isolating switch and mechanism, and interlocking. It organically combines the three functions of breaking, isolation and interlocking.Air insulation, safe and reliable
The pole of the rotary circuit breaker is used to realize the function of the isolating switch, which saves the upper and lower isolating switches, so as to realize the purpose of using air insulation and miniaturization. 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. At the same time, the shielding valve of the contact box is also made of metal, which meets the requirements of metal armor interval.
Simple circuit, less heat source
The main circuit is connected by the main busbar arranged in the longitudinal horizontal direction with the upper end contact of the pole post of the longitudinal rotation isolation-breaker, the lower end contact of the pole post of the longitudinal rotation isolation-breaker 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
The overall dimensions of the ZXYN-40.5kV longitudinal rotary cabinet are: 1200mm (width) X2100mm (depth) X2300mm mm (height), and the center distance between phases is 450mm, which is smaller than other air-insulated cabinets of the same kind.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. -
