电气间隙:导电体间测的最短空间经历。爬电距离:导电体间测的最短表面绝缘距离。

1.对于AC-DC电源    (没PFC电路及额定电压110V-240V)

                                   电气间隙 (mm)                爬电距离(mm)

L线 -N线(保险前)           2.0                                            2.5

输入地(整流桥前)           2.0                                            2.5

输入地(整流桥后)           2.2                                            3.2

输入-输出(变压器)          4.6                                           6.4

输入-输出(除变压器外)    4.5                                            5.5

输入-输出(磁心)             2. 0                                           2.5

 

2.对于AC-DC电源    (有PFC电路及额定电压110V-240V)                                       

                                电气间隙 (mm)              爬电距离(mm)

L线 -N线(保险前)           2.0                                            2.5                          

输入地(整流桥前)           2.0                                            2.5

输入地(整流桥后)           2.2                                            3.2

输入-输出(变压器)          5.2                                           7.5

输入-输出(除变压器外)    4.5                                           6.4

输入-输出(磁心)             2. 2                                          3.2

你好,请帮忙指导一下。

这几个距离是怎么算出来的,感谢。

输入地(整流桥后)
