按照associated controlgear的定义，它是给特定仪器供电的，可以在特定仪器内或外，那在外面的时候可不可以是独立式？

(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）。" ~0 A# u3 M$ S7 h( e( x2 |7 D

由此看来，装不装在器具内部，有没有自身的外壳，不是区分associated和independent的重点。

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。( c0 P$ y: K) \. A

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。 |
