一体式是什么意思呢 . ]2 Y1 C2 N" G/ L# y% R

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)

' a' ^* G7 L9 Gassociated 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）。( Y1 D6 m; U: W1 L

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。; e4 W# J/ ^) J! z/ O
3 p$ H9 A; j5 b) G8 A( k
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。
