ZW20-12F outdoor intelligent demarcation vacuum circuit breaker Series vacuum circuit breaker is a high-voltage outdoor switchgear with isolated combination circuit breaker, rated voltage 12KV, three-phase AC 50HZ, built-in voltage 12KV to 220V operating voltage, It is mainly used to break load currents, overload currents, and short-circuit currents in rural power grids, urban grids, and small power systems. The overall structure of the product is a three-phase common box type. The three-phase vacuum arc extinguishing chamber is placed in a metal box. The SMC insulation material is used for phase insulation and ground insulation. The performance is reliable and the insulation strength is high. This product can also be equipped with a reclosing controller for use in applications where easy power is available. PT type and reclosing controllers are used in applications where there is no power supply. Smart circuit breakers are suitable for radial power supply and ring power supply systems to help the system eliminate transient faults. , Automatically restore power supply, can also isolate the fault, and realize distribution automation. Third, ZW20-12F outdoor high voltage vacuum circuit breaker use environment: 1, ambient air temperature: -40 °C ~ +40 °C; day temperature difference: the daily temperature change is not more than 25 °C; According to SF6 gas substance properties, when the ambient temperature is -40 °C, such as the cabinet Inner Mongolia preferential sales ZW20-12FG/630 intelligent demarcation switch brand Department pressure is 0.05Mpa, at this time SF6 is still gaseous, to ensure the normal operation of the product. (When the ambient temperature is -40 °C and the gauge pressure is 0.05Mpa, the SF6 liquefaction point is -55 °C; Zero gauge pressure, SF6 liquefaction point will not exceed -60 °C). 2, the wind speed is not more than 35m/s; 3, no flammable, explosive danger, strong chemical corrosion (such as various acids, alkalis or smoke, etc.) and severe vibration of the place. 4, Altitude: ≤1000m; 5, Cover thickness: 10mm; 6, air pollution degree: IV level; 7, earthquake intensity: ≤ 7 degrees; 8. Grid Neutral Point Grounding Mode: Neutral point is ungrounded, neutral point is arc-extinguished coil grounded, and neutral point is grounded by low resistance. Fourth, ZW20-12F outdoor high voltage vacuum circuit breaker operating power: ZW20-12 outdoor high voltage vacuum circuit breaker needs to operate the power when working. The operating current can be external AC or DC 220V power supply, but it is generally on the 10KV line external operation.
