#1 家里一下子烧坏好几个电器
现在的房子住了几年了之前都没有电压surge的问题。最近几个月突然开始有问题,在不同时间烧坏了几个surge protector/power strip,但是没有跳过闸。
前两天突然一下同时烧坏了不同房间的几个电器,包括cable modem,打印机,电饭锅。
不太确定是什么引起的。是入室的电压突变 还是室内的电路自己引起的问题? 去年夏天装好的solar roof,加了一个额外的panel,但是电压问题是近几个月开始出现的。最近这次是用微波炉时突然烧坏电器的,但前几次记不清楚是不是每次都有用微波炉了,第一次时并没太在意。微波炉是built-in那种,看不到插头或者电线的连接,如果地线老化了能影响整个house的电路吗?
这种情况怎么处理比较好?

做error isolation。有没有实时监控电压的装置,不用一直显示,但可以自动记录下来一段时间,然后形成图表的那种?把太阳能系统和主要供电系统断开一阵试试?

微波炉和烤炉是一体嵌入在柜子里那种,根本看不到接线。看来只能拆下来了。
监控电压的话监控哪里的插口呢?哪里买这种装置? 目前平均几周可能发生一次这种烧坏东西的事。
问了一个电工说一定是电网的问题。可是我觉得并不太像啊。

一般公司用的非手持式(台式)的万用表都有按时间记录的功能,家用的比较少见有此功能。那就用手持万用表的最大电压锁定功能。另外,本坛前一段有关于surge 保护器的,那是对外界雷雨保护的。不知道是否有帮助。反正不贵,装一个呗。

另外,那些一直接电的小电器,比如电饭锅,modem,打印机,都通过一个有浪涌保护的插线排后再接上,就是说不要直接接墙上的电插孔。这种插线排不算贵,相当于给你的电器加了个保险缓冲。在问题没找出来之前,可以缓和一下。

家里供电是一个变压器出来的,即使220伏特插座也跟其他插座有关联。微波炉高压漏电可以传遍所有插座
楼主可以找一个退役的router或modem再实验一下开微波炉时是不是会烧坏。实验时把其他电器断开

美国入家供电是分相电,一个变压器上三个抽头,分别是火线A和火线B以及零线。零线跟地线相连。如果地线不接地了,也会造成某些插口电压异常,但对电压通用在110-220伏特的电器影响不大

AI 的看法:
a malfunctioning microwave oven can potentially cause high voltage surges in a house's electrical system under certain circumstances. Here's how:
Electrical arcing: If there is an electrical arcing or short circuit inside the microwave oven, it can draw a large amount of current from the electrical circuit, causing voltage fluctuations and surges.
Transformer failure: Microwave ovens contain a high-voltage transformer that steps up the household voltage to several thousand volts for generating microwaves. If this transformer fails or develops a short circuit, it can send high voltage spikes back into the household electrical system.
Magnetron failure: The magnetron, which is the component responsible for generating microwaves, can also fail and cause voltage surges if it short-circuits or experiences arcing.
Wiring issues: Loose or faulty wiring connections within the microwave oven or in the electrical circuit supplying power to it can also lead to voltage surges and fluctuations.
These voltage surges can potentially damage other electrical appliances and electronics connected to the same electrical circuit or even the entire household electrical system if the surges are severe enough.
To prevent such issues, it's important to maintain and regularly inspect microwave ovens for any signs of malfunction or wear and tear. If you notice any unusual behavior, such as sparking, burning smells, or flickering lights, it's advisable to unplug the microwave oven and have it inspected by a qualified technician.
