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?

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
1 _( j7 V7 @, X5 _) q3 B(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)

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。
