Product Description
1.Application &Feature
This series of vacuum contactor is mainly used for AC 50-60Hz,the main circuit rated voltage 1.14kV below,the rated current from 160A to 1000A power network systems for remote making and breaking and frequent starting and control of AC motors, transformers and capacitor banks and other occasions.This series of vacuum contactor conform to the GB14048.4 standard,to current
international advanced level.The contactor with vacuum switch tube for arcing element,have no arcing,long life,without noise,small volume,safety, reliability,etc.
Advantages:good compatibility,stable and reliable performance,free maintenance and long service life.
2.The use of the environment conditions
2.1.Ambient temperature:-25 ºC ~ +40 ºC.
2.2.Installation site altitude does not exceed 2000m.
2.3.The relative humidity of the air,the wettest month average monthly maximum relative humidity of 90%,monthly average minimum temperature of 25ºC,and taking into account the cream of temperature changes on the surface of the product.
2.4.Environment:anhydrous invasion,non-corrosive and flammable gas and excessive vibration occasions.3.Operation and Maintenance
3.1.When using,firstly connect the ground wire,then connect the rated control voltage to the contactor power terminal.
3.2.The contactor has been adjusted well in the factory,in gerenal no need to adjust again.
3.3.For the newly exchanged vacuum switch tube,the vacuum degree can be checked by the power frequency withstand voltage method.Withstand voltage up to 10kV for 1 minute should no breakdown and no flashover phenomenon.If this condition is not available,could use 5000Vmegohmmeter to measure the vacuum switch tube insulation resistance.Insulation resistance of new vacuum switch tube should be more than 1000MΩ.Long-term use of vacuum switch tube insulation resistance should be more than 20MΩ(Test must ensure that the vacuum switch tube's appearance is clean and dry).
3.4.If have one of the following cases,we should check and adjust the vacuum contactor.
1).It's about six months since first time using.
2).Frequent operation place, operation 100000 times.
3).Find the vacuum switch tube contact open distance less than 1.5 mm,over
travel is less than 0.5 mm.
4).After replace vacuum switch tube.
5).Mechanical operation have abnormal.4.Detailed Technical Parameter
