2.5 Electric strength
2.5.1 This test shall not apply to lamps having caps with internal resistors.
2.5.2 The insulation between the shell of the cap and the pin(s) or contacts shall withstand the test voltage. No flash-over or breakdown shall occur during the test.
2.5.3 Compliance is checked with a 1 500 V a.c. voltage of substantially sine-wave form, with a frequency of 50 Hz or 60 Hz and applied for 1 min. Initially, not more than half the prescribed voltage shall be applied; it shall then be raised rapidly to the full value.
Glow discharges without a drop in voltage are neglected.作者: 622 时间: 2012-1-27 17:29
谁能解释一下，为什么针脚到金属帽之间的耐压测试是1500Vac吗？我们的危险带电体与可接触部件之间一般进行3000Vac以上的耐压测试呀。现在的1500Vac是从哪个角度考虑的？作者: mdjljqmcy 时间: 2012-1-27 17:29
