Product Introduction

The ZW20-12 (ZW20B-12) outdoor pole-mounted high-voltage vacuum circuit breaker is an outdoor high-voltage switchgear with a rated voltage of 12kV and a three-phase AC 50Hz. Mainly used for breaking and closing the load current, overload current and short circuit current of the power system.
It is suitable for the protection and control of substations, industrial and mining enterprises and urban and rural power distribution networks, and is especially suitable for places with frequent operations and urban automation power distribution networks. This product is matched with the controller, which can meet the requirements of the distribution automation system and can reliably and effectively complete the traditional recloser function.

Technical characteristics
Electrical connection through aviation socket and outdoor sealed control cable, with fault detection function, protection control function and communication function reliable judgment, detection of zero sequence current and interphase short circuit fault current in and out of the field, and automatic removal of single-phase ground fault The main body switch of the short circuit fault between phases and phases is vacuum extinguishing and SF6 gas insulation. The box body refers to the gas seal of Toshiba, Japan, explosion-proof, and the insulation structure technology has the excellent overall sealing performance. The SF6 gas-filled inside does not leak and is not affected by the outside world.

Normal service condition:

1. Ambient air temperature: -40℃~+40℃; daily temperature difference: daily temperature change is not more than 25℃; According to the material properties of SF6 gas, when the ambient temperature is -40℃, if the air pressure inside the cabinet is 0.05Mpa, this When the SF6 is still in gaseous state, 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; at zero gauge pressure, the SF6 liquefaction point will not exceed -60°C).
2. The wind speed is not more than 35m/s;
3. There is no place where there is flammability, explosion hazard, strong chemical corrosives (such as various acids, alkalis or dense smoke, etc.) and severe vibration.
4. Altitude: ≤1000m;
5. Covering thickness: 10mm;
6. Air pollution degree: Level IV;
7. Earthquake intensity: ≤7 degrees;
8. The neutral point grounding method of the power grid: the neutral point is not grounded, the neutral point is grounded through the arc suppression coil, and the neutral point is grounded through low resistance.
