Product Description
1.Product overview:
This series of vacuum contactor is suitable for AC 50~60Hz,main circuit rated voltage 1140V, main circuit rated current from 160A to 1000A power network system for remote making and breaking and frequent starting and controlling AC motors, transformers and capacitor banks.
This series of vacuum contactor is divided into two types: the electromagnetic holding type and permanent magnet type. Totally enclosed structure, beautiful, elegant, stable and reliable in performance, maintenance free, and have a long service life.
Product features:
1).Adopts an integral insulating frame structure, with high-quality vacuum switch tubes, the secondary control is simple and reliable, and the performance is stable.
2).The vacuum contactor has a fast action speed, which shortens the arcing time and improves the safety and reliability of the product.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.Vacuum 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).
