绝缘系统
我刚接触安规这个行业，UL测试工程师告诉我绝缘tap要包含在绝缘系统里报告才能报备这个tap。我以为绝缘系统是变压器最外面的那个tap，结果不是，哪位高手能不能帮我解释一下啊？ 绝缘系统 针对的是变压器整体的，不是单个某个部位，各个部位都要满足相应的温度 绝缘。60950里面有A E B F H绝缘等级 引用第0楼amanda0925于2010-10-25 16:18发表的 绝缘系统 :

是不是绝缘tape啊??? 绝缘系统是由客户提供的. 看下标准《ul446Systems of Insulating Materials– General》应该有帮助，其中INSULATION SYSTEM定义为：
“A unique intimate combination of two or more insulating materials used in
electrical equipment. One example of this is the combination of magnet wire, ground insulation, varnish,
lead wire insulations, and outer wrapping of a coil. These intimate combinations are evaluated as
unique groups. When multiple groups exist, either within a given insulation system or a different
insulation system, components of one unique group shall not be added to another unique group.
However, more than one group is able to be used within a single device when at least a 3.05 mm
(0.125 inch) air space is used to separate them. Any material or component existing outside the outer
wrap of the device or not in contact with the windings is not determined to be part of the insulation
system.” Insulation System : An intimate
Combination of Insulating Materials used in
Electrical Equipment.
For Example : the combination of a coil form,
separators, magnet wire coating, lead wire
insulators and other wrapping of a relay coil 每個公司的絕緣系統是不一樣的(除非是copy來源完全一致),你應該對照你所在公司對應此類產品的絕緣系統列名元器件管制清單使用才能滿足 normally insulation system is combined with motor or transformer, and it should include many materials, tap is tape?? 引用第5楼daxia121于2010-10-26 09:25发表的:

绝缘系统应该包含TAPE（绝缘胶纸）吧。 如果是变压器的绝缘系统，可能是指缠在绕组上起隔离作用的胶带吧。
