Product Description
Applications and feature
JCZ9 series AC high voltage vacuum contactor is suitable for AC 50 ~ 60HZ,rated voltage of the main circuit voltage 40.5kV,rated current from 160A to 1250A power network system for remote making and breaking and frequent starting and controlling AC motors, transformers and capacitor banks and other occasions.This series contactor have the feature of long life time ,good performance.
Contactor normal working conditions
Ambient temperature -25 ºC ~ +40 ºC.
Installation site altitude does not exceed 2000m.
The relative humidity of the air , the wettest month average monthly maximum relative humidity of 90%,monthly average minimum temperature of 25°C,and taking into account the cream of temperature changes on the surface of the product.
Environment:anhydrous invasion,non-corrosive and flammable gas and excessive vibrati- on occasions.
Action PerformanceWhen the ambient air temperature is -25 ºC ~ +40 ºC,the contactor control supply voltage in the range of ratings(rated voltage) of 85-110% should be able to reliably pull.Use contacts in the coal mine,in the control power supply voltage rating (rated voltage) in the range of 75-110% should be able to reliably pull. Release voltage should not be higher than the rated voltage control supply voltage (rated voltage) of 75% at rated frequency AC voltage release should not be less than 20% us, DC is not less than 10% us.
Use and Maintenance
First take a good ground wiring connection when used,and then connected the rated control voltage to the terminals of the contactor power board (have left).
The contactor must be installed RC overvoltage protection devices and auxiliary circuits snubber capacitor.RC overvoltage protection device connected to the three leads contactor output (user-supplied).
When the contactor factory adjusted, generally without adjustment.
For a new replacement vacuum switch, power frequency voltage method can be used to check the degree of vacuum,pressure reaches 10kv lasted 1min,should be no breakdown,no flashover.No such condition can be 5000v megger insulation resistance test switch.The new vacuum switch tube insulation resistance should be greater than 1000Μ.Long-term use of the insulation resistance should be greater than the vacuum switch tubes 20ΜΩ(must ensure that the test vacuum switch looks clean and dry).
Where belong to one of the following conditions, and the contactor should check and adjust.
A,From the start to run after six months.
B,The more frequent operating sites, each operating 100,000 times;
C,Found that vacuum switch tube contacts the spacing less than 1.5 mm, the ultra-distance less than 0.5 mm,
D,When replace the vacuum switch tube;
E,Mechanical operation is an exception.
Product structure
This series contactor separated by insulating electric frame,metal base,drive crank arm, electromagnetic system,auxiliary switch,vacuum switch parts,split up and down the structure of high-voltage circuit and low voltage control structure layout is beautiful,safe, reliable,easy to install and maintain.Independent insulating frame of each phase,the phase-to-phase insulation is very reliable,the metal base of the product structure is solid, reliable work .
