ZN85-40.5 Indoor High Voltage Vacuum Circuit Breaker

Summary

ZN85-40.5(3AV3) indoor high voltage vacuum circuit breaker is of rated voltage 40.5kV, three-phase and AC 50/60Hz. It applies to mining firms, power house and substation acting as protection and control electric apparatus. It is also applicable in occasions with frequent operation.

Ambient condition

1. Altitude: ≤1000m;2. Ambient temperature: -25℃~+40℃;3. Relative humidity: daily average ≤95％, monthly average ≤90％;4. Earthquake intensity: ≤8 degree;5. Applicable occasions should free from inflammables, explosives, corrosivesand severe vibration.

Structure feature

1. The arc-extinguish chamber is on the upper part and the mechanism is on the lower part. This structure is convenient for debug.2. Complex insulating structure using air and organic material; Compactable dimension and small weight.3. Vacuum arc-extinguish chamber of Cutler-Hammer Company (USA) and domestic ZMD are both applicable for the VCB. Both twokinds of chambers extinguish arc by vertical magnetic field and featuring with low cut-off and good on-off capability with asymmetry.4. Simple spring operation mechanism is free from maintenance within 10000 times of operations.5. Lead-screw propeller, easy and stable operation and good self-locking capability.
