ZN63A (VS1)-12 Fixed Indoor High Voltage Vacuum Circuit Breaker

Overview

ZN63A(VS1)-12 series indoor fixed high-voltage vacuum circuit breaker is an indoor switchgear with three-phase AC 50Hz and rated voltage of 12kV. It can be used for control and protection of industrial and mining enterprises, power plants, substations, and electrical facilities. And suitable for places with frequent operations. The operating mechanism is integrated with the circuit breaker body, and the design can be used as a fixed installation unit, or it can be equipped with a special propulsion mechanism to form a handcart unit. The main circuit part can use the integral solid-sealed pole to realize the miniaturization, high reliability and maintenance-free of the circuit breaker.

Normal Use Environment

◆Ambient temperature: not higher than 40℃, not lower than -10℃ (storage and transportation at -30℃ are allowed).
◆Altitude: no more than 1000m. (If the altitude needs to be increased, the rated insulation level will be increased accordingly)
◆Relative humidity: the daily average is not more than 95%, the daily average of saturated vapor pressure is MPa, and the monthly average is not more than 1.8×10.
◆Earthquake intensity: no more than 8.
◆A place without fire, explosion, serious pollution, chemical corrosion and severe vibration.

Environmental Conditions

1. Ambient air temperature: -5~+40, 24h average temperature does not exceed +35.
2. Install and use indoors. The altitude of the work site shall not exceed 2000M.
3. At maximum temperature +40, the relative humidity should not exceed 50%. Higher relative humidity is allowed at lower temperatures. predecessor. 90% at +20. However, due to changes in temperature, it is possible to inadvertently produce moderate dew.
4. The installation slope should not exceed 5.
5. Install it in places without severe vibration and impact, and in places with insufficient corrosion to electrical components.
6. For any specific requirements, please negotiate with the manufacturer.
