請教負離子產生器放電端輸出電壓量測方法與空間沿面距離
各位資深的大大們想請問負離子產生器如何去量測輸出端放電的電壓與
要依他工作電壓如何判定空間沿面距離??
請各位大大幫幫忙~~謝謝!!
负离子一般串联保护阻抗,电压虽高,但电流较小,不足以电死人,只要满足8.1.4的要求就不属于带电部件了,那么就不用考虑爬电距离。用示波器测量。
not exceed 2 mA for d.c., its peak value shall not exceed 0,7 mA for a.c. and
– for voltages having a peak value over 42,4 V up to and including 450 V, the capacitance shall not exceed 0,1 uF
– for voltages having a peak value over 450 V up to and including 15 kV, the discharge shall not exceed 45 uC
– for voltages having a peak value over 15 kV, the energy in the discharge shall not exceed 350 mJ.
Compliance is checked by measurement, the appliance being supplied at rated voltage.
Voltages and currents are measured between the relevant parts and each pole of the supply source. Discharges are measured immediately after the interruption of the supply. The quantity of electricity and energy in the discharge is measured using a resistor having a nominal non-inductive resistance of 2 000 ohms 其电压可用负电压测试仪测试, 但具体是什么仪器, 现在不记清. 另外, 其常不串联保护阻抗, 电流小不假. stey 发表于 2012-8-20 13:31 static/image/common/back.gif

输出端对地串一2000欧无感电阻,用示波器探头接到电阻两端,示波器读出电压值再除以2000欧,得出电流值。测得的DC电流不超过2mA,AC不超过0.7mA。 stey 发表于 2012-8-20 15:40 static/image/common/back.gif

先感謝大大~~慷慨解囊
我試試看~~~ 那个电压只能用静电电位计,近万伏,不是谁都能测。其他听美女说的。
