我们有款电子式的电饭煲(适用60335-2-15),PCB板上有个0.1UF的X2电容器,是否需要测试插头两端的电压,且不能超过34V?我们的产品太给力了,插头拔掉1秒后有117V,( y3 Z- X* ]8 \9 C) E7 q& i$ |5 m) b
按标准的意思,超过0.1UF才要测试,这个超过是不是包含0.1UF?在语文的思维来说,应该小于或等于0.1UF不用测试的。2 }1 @3 N* `1 l4 F; m" V( C

Any switch is then placed in the off position and the appliance is disconnected from the supply mains at the instant of voltage peak. One second after disconnection, the voltage between the pins of the plug is measured with an instrument that does not appreciably affect the value to be measured. The voltage shall not exceed 34 V. ; l6 ^* x$ r8 {4 m7 i% @

Dear Luqing, Sorry that maybe it is a late notice, we have done the plug discharged test, although base on your circuit, it has a 0,1UF X2 capacitor, but the discharge voltage after 1 sec is very high, from 76 V to 117 V. In this case, it needs to add the breeding resistor parallel to the X cap. Please study it and come back to me with the solution. Thanks. Vriendelijke groet / Mit freundlichen Grüßen / Best regards / 以此致敬意 Mr. C.S. Man
