Product Description
1.Product descriptions and Product features:
CKG4-12KV vacuum contactor is suitable for AC 50~60Hz,main circuit rated voltage 12kV,rated current from 160A to 6300A power network system for remote making and breaking and frequent starting and controlling AC motors,transformers,capacitor banks and other occasions .
This series of vacuum contactors used switched capacitor vacuum switching tube and insulating bracket, metal frame firmly into one, safe and reliable. The agency travel and breaking capacity, together, opening bounce is small, stable, three-phase over the same period type.
Product features:
1.1.This kind of vacuum contactor has 2 models: the electromagnetic holding type and the permanent magnet type and the secondary control is simple and reliable.
1.2.Especially has good performance in the capacitor banks.
1.3.Vacuum contactor main contact has the small bounce,avoid or reduce the re-ignition probability of the switch,protect the line.
1.4.Vacuum contactor action fast,shortens the arcing time,Improves product safety and reliability.
1.5.Long mechanical life,switch close/open is reliable.
1.6.The operating mechanism is the fully enclosed mechanism,smaller influenced by the outside environment and lower failure rate.
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.Use requirements
3.1.Select the contactor technical parameters correctly,including the auxiliary switch contacts can not be overloaded use.
3.2.Contactor around and above to leave enough insulation space to ensure safety of use.
3.3.When the control power is turned on,but no reaction,cut off the control power immediately to check the reasons to avoid burning the solenoid coil.
3.4.The electromagnetic system have strong magnetic attraction when it's working,we should keep the things with ferromagnetic material away form the machine.
3.5.The main circuit connection principle is:the upper end (static end) is the incoming terminal,the lower end (moving end) is the outgoing end.
4.Product Specification
Rated voltage:12kV, rated current:160A,250A ,400A ,630A,800A and1000A.
5.Product structure
This series of contactor is composed of insulating frame,driving crank arm, electromagnetic system,auxiliary switch,vacuum switch tube and other components.The structure of high voltage circuit and low voltage control upper and lower split structure,with layout beautiful,safe and reliable,easy to install and maintain.
6.Maintenance
6.1.We recommend the user establish a regular maintenance system to ensure that the vacuum contactor is in good condition.Periodically clean the insulation frame,the vacuum switch tube and circuit system to ensure work insulation and normal operation.
6.2.Check if the fasteners are loose and the structure components are abnormal.
6.3.Auxiliary switch should be normal operation and good contact.
6.4.Check if the open distance and the overtravel meets the requirements.
6.5.Check if the electrical wiring is loose,and make sure it is firmly connected.
6.6.Vacuum switch tube vacuum degree test,in general use the power frequency withstand voltage method to check,the withstand voltage value should not be less than 1/2 of the rated value.
