2.問題描述(請詳述問題在哪):
樓梯間電燈是用PL-C 26W/840/2P,
因不好買又貴,想換成一般的螺旋燈泡。
拆下燈具後,電燈孔有兩條線,以下稱A,B
分別量測對地電壓(電錶負極接燈孔座金屬框)
A線 維持222V
B線 開關ON: 224V 開關OFF: 63V
B線確定是開關控制線,但OFF時還有63V
(漏電流產生的分壓電壓?)
我納悶的是為什麼A跟B都是火線?不是一條110V另一條0V?
這樣要改裝成螺旋燈具的話要怎麼做?
PS: 我看其他住戶的改法是把原本燈具的220v/60Hz安定器拿來用
A線220V先過安定器再接去110V的螺旋燈泡,B線則直接接螺旋燈泡
他們的燈用120V白光23W,感覺比我自己房間的23W還亮很多,
不知道會不會很快就燒了。
