LWKK®无功补偿电容器专用接触器
LWKK®Reactive compensation capacitor special contactor
由于电容器投入运行的瞬间会有极大的高频涌流通过接触器的开关触头,所以要实现每一次投切的安全性,接触器必须有可靠的短时限流能力做保证。当投切完成并进入稳定工作状态后,回路实际电流长期在系统电压波动及谐波电流叠加的影响下持续偏高,有时可达1.3~1.4In,对于稳态要求,LWKK®电容器专用接触器过硬的材质条件充分满足对约定发热电流的要求,实现安全工作和更长的使用寿命。
由于电容器的输出容量会受电压和温度影响,接触器约定发热电流推荐从大选配。接触器线圈电压AC220V,辅助触点的个数请在订货时书面确认,可使用系统电压范围220V~660V
As a greatlarge high-frequency inrush current passes the switch contact of the contactorat the moment when the capacitor is put into operation, to achieve the safetyof each switching, the contactor must have reliable short-time currentlimiting capacity for this. When the switching is completed and the deviceenters into the stable working condition, the actual current in the circuitwill be continuously high under the influence of the system voltagefluctuations and harmonic current superposition for a long time, sometimes upto 1.3 ~ 1.4In; forsteady-state requirements, a special contactor of LWKK® capacitor ismade of excellent hard material, to fully meet the requirements of conventionalthermal current, achieving safe work and longer service life.
As the outputcapacity of the capacitor will be affected by voltage and temperature, thecontactor's conventional thermal current is recommended from the large value. Contactor coil voltage is AC220V, and the number of auxiliary contactsshall be confirmed in writing when ordering; the system voltage range is 220V ~660V.
