对于 assciated 和 independent的理解，可以参看IEC 61558-1中对类似类型变压器的解释3.1.6, 3.1.6.1, 3.1.6.2以及3.1.74 X' x7 g% ?# U2 N( Z
(61347-2-13在定义上极大程度地借鉴了IEC 61558-1, 当然一个是针对变压器，一个是针对控制装置)

associated 可以是incorporated （装在器具内部，需要依赖器具外壳来防触电）和specific use(可以在器具内部或者是在器具外部，可以依赖自身的外壳来防触电）。/ q6 w" K0 Z8 P

区分的重点在于associated是给特定的设备供电的（例如61347－2－13拿应急照明装置的情况来举了一个例子）;而indepedent是可以给不特定的设备供电的。

61347－2－13中提及的independent，特指可以给不特定照明设备供电的控制装置。 |
