好太太油烟机为什么一开灯抽油烟机就不能用了

肯定是线路有问题，至于你的不能使用是什么概念？是电机不转了还是什么都不行了？一般如果说烟机的照明灯会亮，但是电机不转的话，一般是电路板里的电容出问题了，一般用的是5微伏的电容，换一个就行了！——美敦电器为您解答！

如图所示电路中，电源电压u=311sinl00πt（V），A、B间接有“220V，440W”的电暖宝、“220V，220W”的抽油烟机、交流电压表及保险丝．下列说法正确的是（　　）A．电路要正常工作，保险丝的额定电流不能小于3AB．交流电压表的示数为311&V，频率为50HzC．电暖宝发热功率是抽油烟机发热功率的2倍D．工作2min抽油烟机消耗的电能为2.64×104J
A、由P=UI得，I=，故干路电流为I=，故A错误；B、交流电压表的示数为有效值，故B错误；C、电暖宝是纯电阻，消耗的电能全部转化为内能，产生热量，而抽油烟机是非纯电阻，耗的电能部分转化为机械能，部分转化为内能产生热量．电暖宝发热功率是抽油烟机总功率的2倍，故C错误；D、2min抽油烟机消耗的电能为W=Pt=2.64×104J，故D正确．故选：D．
本题考点：
电功、电功率；焦耳定律．
问题解析：
交流电压表的示数为有效值，由公式P=UI知电路要正常工作，干路中电流为3A，电暖宝是纯电阻，而抽油烟机是非纯电阻．（2011o齐齐哈尔）小艳同学某天在家开灯时，灯不亮，经检查发现保险丝被烧断．她在爸爸的协助下用一盏标有“220V

（2011o齐齐哈尔）小艳同学某天在家开灯时，灯不亮，经检查发现保险丝被烧断．她在爸爸的协助下用一盏标有“220V&&40W”的灯泡L0（检验灯泡）取代保险丝接入电路，如图所示．然后进行如下操作，并观察到相应的现象：当只闭合开关S1时，L0和L1均发光，但都比正常发光暗；当只闭合开关S2时，L0正常发光，L2不发光．由此可以判断（　　）A．L1和L2所在的支路均短路B．L1所在的支路完好，L2所在的支路短路C．L1所在的支路完好，L2所在的支路断路D．L1所在的支路短路，L2所在的支路断路
（1）当只闭合开关S1时，L0和L1均发光，但都比正常发光，是因为L0与L1串联，两个灯得到的电压小于220V，故不能正常发光，说明该支路是通路，是正常的；（2）当只闭合开关S2时，L0正常发光，L2不发光，说明L0得到了220V的电压，该支路是发生了短路．故选B．
本题考点：
家庭电路的故障分析．
问题解析：
将额定电压220V的“校验灯”，取代保险丝接入电路，相当于把此灯串联入电路中，它会有三种状态：“校验灯”恰能正常发光，说明该支路短路，“校验灯”发光不正常（暗红色）说明该支路工作正常，“校验灯”不发光说明该支路断路．抽油烟机刚启动转,转一下烧保险丝什么原因?_百度知道
抽油烟机刚启动转,转一下烧保险丝什么原因?
排油烟机内部的电线短路了，只有短路了才有这种情况，检查看看哪儿漏电了，哪儿掉线了，哪儿电线接触到一起了，哪儿的电线外皮破了导致短路了，总之好好查查线路，就会发现问题，这种事情用电笔一测就知道了。

We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you to live green life.
Remember these three words: reduce, reuse and recycle.
Reduce means"use less". Don"t waste things. This saves money and reduces pollution and waste goinginto the environment. Before we buy something new, think if it is really necessary or maybe the old one willbe just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.
Reuse means"use again". Use things for as long as possible. When we buy things, make sure that they lasta long time. We should take care of them so that they will last, and we should repair them if we can insteadof throwing them away and buying new ones. Don"t use a paper cup or a paper bag. It"s better to use a china cup and a lunch box because you can use them again.
Recycle means"change things into something else". Although it takes energy to change something into something else, it"s better than throwing things away or burning them. Find out what can be recycled in yourneighborhood and take part in recycling programmes. We should also buy products made from recycledmaterials, such as recycled paper, to help save trees.
