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？8 ` u# b( K- F4 G

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3.1.7
6 ^( h$ G+ E: a, I- J8 Y& d(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）。

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。9 J: u& A t! ^/ N; Y
