请教测温升时的电压问题
各位好,在此请教一下灯具测温升时的工作电压标准?如额定工作电压是AC220V,我在做温升测试时点灯时的电压是按220V还是要220*1.1=242V.还是其他电压,我们的代理是按220*1.1*1.06=256V来测试的。这应该是家电标准吧,灯具没有找到这样的说法。当然是…………按标准做,什么灯就按什么灯的标准:lol 灯具分类型的哦 LED是1.06倍 除特低电压以外的钨丝灯的温升是光源达到1.05倍额定功率时的电压,其它灯具是1.06倍额定电压. 学习了
:) 除了钨丝灯,其他都是按照1.06倍的额定电压,你的光源应该是LED吧。 如果是欧规,按EN 60598-1的这项来.
d) The test voltage for the luminaire shall be as follows.
– Filament lamp luminaires other than ELV: that voltage which produces 1,05 times the
rated wattage of the test lamp (see Annex B) except that heat test source (HTS) lamps
are always operated at the voltage marked on the lamp.
– For other luminaires 1,06 times the rated voltage or the maximum of the rated voltage
range.
– For motors contained in luminaires: 1,06 times the rated voltage (or the maximum of the
rated voltage range of the luminaire).
Exception
For determination of the average temperature of the winding of a component with tw
marking and for the determination of the case temperature of a component with tc marking,
except capacitors, the test voltage shall be 1,00 times the rated voltage. This exception
applies only to the measurement of the winding or case temperature and does not apply, for
example, to the measurement of a terminal block on the same component.
Capacitors whether carrying tc or not are tested at 1,06 times rated voltage when operated
within fluorescent and other discharge luminaires.
NOTE 1 If a luminaire contains both a filament lamp and a tubular fluorescent or other discharge lamp or a
motor, it may be necessary to provide it temporarily with two separate supplies. 了解一下,学习了! 谢谢各位的回复。
