XGN66-12 Switch Cabinet Intelligent Control Power Distribution System

XGN66-12 Switch Cabinet Intelligent Control Power Distribution System

This product has absorbed foreign advanced technology, it is small in size, which is only 50% of the protection of ordinary switch cabinet; the circuit breaker has high reliability and good performance,”Five The “anti-” interlocking mechanism is reliable and simple. The switch cabinet is an indoor complete set of 3.6, 7.2, 12KV three-phase alternating current 50HZ single busbar segmentation, as To receive and distribute electrical energy. It also has the functions of controlling, protecting and monitoring circuits, and can be used in various types of power plants, substations, and industrial and mining enterprises.High-rise buildings and other places can also be combined with the ring network to be used in opening and closing stations.

Normal use environmental conditions

  1. Ambient temperature: -25°C~+40°C, the average temperature within 24 hours does not exceed +35°C.
    2. The altitude does not exceed 1000m.
    3. The horizontal inclination is not more than 3°C.
    4. The seismic intensity does not exceed 8°C
    5. There is no violent vibration, shock and explosion hazard place.

Structural features

  1. The cabinet body is welded with high-quality angle steel.
    2. The circuit breaker room is located in the middle (lower) part of the cabinet, which is convenient for installation, debugging and maintenance. It is equipped with ZN63A (VS1-12) circuit breaker as standard, and has a pressure release channel to ensure personal safety.
    3. Using advanced and reliable rotary isolating switch, it can safely enter the circuit breaker room for maintenance when the main bus is live.
    4. The protection level of the whole cabinet is IP4X.
    5. Equipped with a reliable and fully functional compulsory mechanical locking device, which can easily and effectively meet the requirements of “five preventions”.
    6. Have a reliable grounding system.
    7. The door is equipped with an observation window, which can clearly observe the working status of the components in the cabinet.
    8. The operating mechanism is locked using the same JSXGN locking mechanism used in the XGN12-12 cabinet, which is simple, reliable, convenient and practical.
    9. The incoming and outgoing cables are lower than the front of the cabinet bottom, which is convenient for users to connect.
