何谓微距断开开关
60335-1 附录H 里面15 Insulation resistance and dielectric strength
Subclause 15.1 is not applicable.
Subclause 15.2 is not applicable.
Subclause 15.3 is applicable for full disconnection and micro-disconnection.
NOTE This test is carried out immediately after the humidity test of subclause 15.3 of IEC 60335-1.
怎样算是micro-disconnection??
micro disconnection
disconnection that provides correct functional performance by contact separation in the case of
long-term temporary overvoltage
我已经找到了。。不用麻烦各位了 距離是多少? 上面印有符号 μ,小间隙开关的符号是 s 。 山炮 发表于 2012-9-13 15:01 static/image/common/back.gif

哦,原来这样,谢谢! micro or full disc;micro,一般用μ标示,电气间隙小于3mm(如果记得没错的话);EN 61058-1上有描述。。。 山炮 发表于 2012-9-13 15:01 static/image/common/back.gif
