8 H# h* c: M- `% O; T9 D从标准意义上来说,放保险丝前面和后面都是允许的,前提是VDR满足标准的相关要求!VDR通过认证,是不需要承受基本绝缘的抗电强度测试,测试时需要断开此元件。 IEC60065"Resistors, capacitors and RC-units complying with 14.1, 14.2.1 and 14.2.2 respectively,; i1 `- X* E; u1 F, T% ]
connected in parallel with the insulations to be tested, are disconnected. Inductors and. t4 o6 ^3 z! X
windings which otherwise would prevent the test from being made, are also disconnected.
" {+ u; I0 v9 D3 hTable 5 – Test voltages for dielectric strength test and values for insulation resistance".可没说要断开压敏电阻来测抗电强。
