EN 60598-1 Abnormal circuit conditions 附录C
各位同学!那位同学做过附录C的测试,看红色字体(灯管与合适的等效电阻的中点连接),合适的等效电阻具体是多大电阻呢?怎么算出来的?谢谢!:)
b) Lamp rectification
1) Luminaires for fluorescent lamps (Figures C.1 and C.2)
This is a fault condition which may occur after extended use in luminaires employing
starterless ballasts with capacitive reactance control. When testing luminaires for the
rectifying effect, the circuit shown in Figure C.1 shall be used. The lamp is connected to
the midpoint of the appropriate equivalent resistors. The rectifier polarity is chosen so
as to give the most unfavourable operating conditions. If necessary, the lamp is started
using a suitable starting device.
标准里面有计算公式的啊,你再看看 Nezof 发表于 2012-12-19 09:46 static/image/common/back.gif

标准上的16.1
In可以根据灯管在IEC60081上面查到的 学习了,
