| High Voltage Outdoor Vacuum Breaker |
|
Model VH7 vacuum breakers are outdoor high-voltage switchgears used in three phase AC 50Hz electric systems with rated voltage of 40.5kV.These products feature anti-condensation, anti-fouling, aging resistance, high temperature resistance, long service life, and stable, reliable, maintenance free operation. This model is primarily used for protection and control in industrial, mining and power facilities, particularly in locations that receive heavy use.A knob insulation method is used, employing high performance insulating cement to seal the quenching pot in a common porcelain bushing. The phase pole is airtight and has a drier inside to ensure highly reliable insulation. Designed to be used at an altitude of 2500m, it may also be used in dirty areas of class IV.With outdoor CT able to be attached on lower outgoing terminals of the breaker, the spring actuator was independently developed according to international outdoor modular design construction principles.Additionally, with movement and speed able to be effectively controlled with an omni-range buffer, the breaker and support frame are split for greater operational performance.
