請(qǐng)教大家IEC60335-1中問(wèn)題

大家好.我現(xiàn)在正在自學(xué)一些安規(guī)知識(shí),其中碰到一些問(wèn)題不好理解,因?yàn)樽约簺](méi)接觸過(guò),特向各位高手請(qǐng)教.不要笑話.
IEC600335-1 8.1.3 - Test probe 41 of IEC 61032 is applied without appreciable force to live part of visible glowing heating element, all poles of which can be disconnected by a single switching action

請(qǐng)問(wèn)當(dāng)中visible glowing heating element 是指什么,在什么產(chǎn)品中可見(jiàn)? all poles of which can be disconnected by a single switching action?這句話又怎么理解

全部回復(fù)(10)

IEC60335 8.1.4 中- for voltages having a peak value over 42.4 up to and including 450V, the capacitance shall not exceed 0.1uf 中 Over 42.4 up to and including 450V 是指由42.4 V 到450V之間嗎? the capacitance 處于電路中哪里?為什么不能超過(guò)0.1UF?

8.1.3 對(duì)Ⅱ類器具以外的其他器具用圖3中所示的試驗(yàn)探棒,而不用試驗(yàn)指和試驗(yàn)銷,用不明顯的力施加于一次開(kāi)關(guān)動(dòng)作而全極斷開(kāi)的可見(jiàn)灼熱電熱元件的帶電部件上.只要與這類元件接觸的支撐件在不取下罩蓋或類似部件情況下,從器具外面明顯可見(jiàn),則該試驗(yàn)探棒也施加于這類支撐件上.
試驗(yàn)探棒應(yīng)不能觸及到這些帶電部件.

3.8.3有解釋此加熱元件須達(dá)650度以上放,才可以當(dāng)灼熱電熱元件(我覺(jué)得烤麵包機(jī)內(nèi)的電熱線就是了)
烤麵包機(jī)都是全極斷開(kāi)的開(kāi)關(guān)動(dòng)作,所以試驗(yàn)棒不碰觸帶電部件,那就ok了

IEC603358.1.4中-forvoltageshavingapeakvalueover42.4uptoandincluding450V,thecapacitanceshallnotexceed0.1uf中Over42.4uptoandincluding450V是指由42.4V到450V之間嗎?thecapacitance處于電路中哪里?為什么不能超過(guò)0.1UF?

8.1.4的測(cè)試我也弄不懂它會(huì)出現(xiàn)在那一些電器具,有那為大大可能說(shuō)明一下?
