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？

" S4 K, A2 I. Q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3.1.77 ^ I; \. P( o6 t& S& _
(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)

" T& l, r1 K$ t( iassociated 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）。

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。& M' `; e+ {3 W9 l" d) u3 U

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。 |
