    大家好，教大家制作一个简单的水满提示装置。只需三个简单的元器件就能制作一个水满提示装置，再也不用担心水溢出来了！我们知道厨房安装有净水器，净水器会产生废水，想利用起来，放一个小桶来装水，但又怕平时没有注意水满出来，我们就想设计一款电路，当水到一定的界限时由蜂鸣器或者LED灯来提醒。于是有了水满提示装置。只需三个元器件，8050NPN一个，发光二极管一个，蜂鸣器一个。焊接好并成为三极管开关电路。接下来就是泡沫装置，这个所要的材料有：一根铁条绕成的U形，泡沫、一片金属片、两个绕成S型的两根导线，一块木块。整个装置的原理是：当水位上升泡沫开关闭合时，三极管的B极接高电平，三极管导通，LED灯亮，蜂鸣器响起来，当断开时，三极管的B极断电，三极管截止。LED灯灭，蜂鸣器不响。起到提示作用。徐州主营AD16系列蜂鸣器厂家现货适用于电力、电讯、机床、船舶、纺织、印刷、矿山机械等设备的线路中的声音信号。

    这三个晶体管都有被击穿的嫌疑。用热风枪吹下这三个晶体管测量其两个结之间的正反向电阻又符合PN结的单向导电性，击穿漏电现象消失。测这三个晶体管在主板上的焊接脚位②脚和③脚间的正反向电阻仍表现为击穿特征，说明这三个晶体管是完好的，短路问题仍在主板上与这三个晶体管②、③脚相关的其他元件或电路上。测主板上的所有电解电容，发现CPU周围的C609-C612、C615～C617的正反向电阻都为5Ω，试取下CPU时，其正向电阻充电至无穷大，反向电阻为505Ω。用放大镜仔细观察，发现CPU插座内一脚的两个铜触片严重变形，紧紧地绞合在一起，通过放大镜观察，用镊子细心地分离开已经绞合在一起的铜触片，并校正好，安上CPU时，这些电容两极间的正反向电阻又都变为5Ω。是CPU内部击穿了吗？设法购回一个DELL厂原装的同型号新主板，测其电源各输入脚与地间的正反向电阻与坏主板比较，看来问题就出在、电源开关机控制绿线和灰线与地间有元件击穿或漏电。测新板Q55的②脚与③脚间正向电阻为615Ω，反向电阻为672Ω，Q54的②脚与③脚间正向电阻为887Ω，反向电阻为1049Ω，Q52的②脚与③脚间的正向电阻为22Ω，反向电阻为24Ω。
