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* @' Z3 c! a! ]# `/ a K& S9 ?

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。5 T; d) i4 P7 T0 E# ]+ v; U

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。 |
