    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。 在一些特例中，可以和LED复用一个控制口 有源蜂鸣器的优点是:程序控制方便。

      LED 是普通白炽灯人7倍。2、省电,在同样的亮度下省电N倍(参考1)3、寿命长,LED相对普通灯的优点1,节能。2,寿命长。3,适用性好,因单颗LED的体积小,可以做成任何形状。4,回应时间短,是ns(纳秒)级别的回应时间,而普通灯具是ms(毫秒)级别的回应时间。5,环保,无有害金属,废弃物容易回收。6,色彩绚丽,发光色彩,光谱范围窄,并能通过红绿蓝三基色混色成七彩或者白光。LED相对普通灯的缺点1,价格贵。2,目前能普遍做到的光效率和理论光效率还有很大差距。3,目前能做到的寿命和理论寿命(10w小时)还有很大差距。4,还是有一定的发热量。5,光衰还可以大幅度缩小。是普通节能灯的2-4倍,是普通白炽灯人10倍以上。9led轨道灯是室内照明灯还是室外照明灯能否用于室是室内装修灯,窒用的话一般用于打背景墙和形象墙,照明的话可以考虑用led筒灯或者吸顶灯###LED轨道灯属于室内照明系列,用于商业照明较多。可根据实际应用需要判定是否使用导轨射灯,可以灵活使用在各种场所###LED轨道灯是室内照明灯,也可以用于室。听朋友说霹雳灯饰的灯具质量很好,你有需要的话可以找这家买。工频耐压：AC1890V 50Hz .5s 绝缘电阻≥100MΩ。 交流指示灯允许电压波动±20% 连续工作寿命≥30000H。虹口区控制箱AD16系列蜂鸣器型号
