SEFR 滤波电抗器
电网中有大量整流、变流、变频装置等谐波源,其产生的高次谐波会严重危害主变及系统中其它电器设备的安全运行。SEWARE SEFR滤波电抗器广泛用于高低压滤波柜中,与滤波电容器相串联,调谐至某一谐振频率,用来吸收电网中相应频率的谐波电流,电抗率有7%、14%等,能消除3、5、7、11、13次及更高次谐波。滤波电抗器与电容器相串联后,不但能有效地吸收电网谐波,而且提高了系统的功率因数,对于系统的安全运行起到了较大的作用。
Usually it is impossible to predict the operating conditions of the reactor, therefore all series reactor SEWER design can withstand harsh operating conditions,the implementation of international standards IEC60289.
通常我们不能预测串联电抗器的运行条件,因此SEWER设计的所有串联电抗器都能承受恶劣的运行条件,执行国际标准IEC60289。
Ambient temperature: Max.temperature +40℃
All low-voltage reactors can be fitted with a temperature control device in the center coil (available for all coils,if requested).
环境温度:低于40℃
在低压电抗器的中间线圈放入温度监控装置(如果需要,每个线圈都可以安装温度监控装置)。
