求变压器初次级绕组不能接触的标准或决议
本帖最后由 lds08080808 于 2021-6-3 13:53 编辑变压器次级绕组是三层绝缘，和初级绕组是否能接触，求相关标准条款，谢谢！
这个还需要决议吗？ 漆包线不认为是绝缘，那么主次级的带电件能接触吗:lol mf0715 发表于 2021-6-3 10:00

是指三层绝缘线与初级，三层线不是认为加强绝缘了吗，好像有标准或决议说明的，但找不到。
即便是现在开关电源的高频变压，主次级之间也有会黄色绝缘胶带隔下，直接贴一起的貌似很少见吧？
另外在GB19212的19.1章节结构里面有说，输入和输出在电气上要彼此隔离。 IEC 61558-1:2017 © IEC 2017 中有提到
Where the insulation on the winding wire is used to provide reinforced insulation in a
wound part:
– the insulated wire (for example polyimide or insulation of equivalent quality) shall
comply with Annex K;
– the insulation of one insulated winding wire shall consist of at least three layers;
– the insulation is subjected to the relevant dielectric strength test of 18.3.
Where the insulated winding wire is wound:
– upon metal or ferrite cores; or
– upon enamelled wire; or
– under enamelled wire,
insulation for mechanical separation which fulfils the dielectric strength test for basic
insulation shall be provided between the insulated wires and the core or between the
insulated wires and the enamelled wires. These independent windings shall not be able to
contact each other or the core. 去试试是不是 PDSH-1031？
