class="neirong"> <div id="MyContent"> <p> 大金空调维修中心告诉员工，空调通常有那些大模块检查</p> <p> 1）、通信电路在检测通信故障时，用万用表交流电压档250V测试，在零线和信号线间如果有电压来回变化且室内机通信指示等持续闪烁，则表明通信正常，否则通信电路有故障。</p> <p> 2）、维修功率模块：在检测功率模块故障时，第一种方法是用万用表二极管档测量功率模块，“+”极与U、V、W极，或U、V、W极与“-”极间正向电阻应约为380-450Ω间，且反向不导通，否则功率模块有故障;第二种方法是用万用表交流电压档，测量功率模块驱动压缩机的电压，其任意两相间的电压应在0~160V之间并且相等，否则功率模块损坏。</p> <p> 3）、维修电抗器：在检测电抗器时，用万用表R X1档进行测量，其绕组电阻值约为1Ω。</p> <p> 4）、维修压缩机：在检测压缩机时，用钳子先拔下U、V、W的导线，测量三相间的电压，若三相间的电压相同，说明压缩机绕组良好，否则压缩机绕组有故障。</p> <p> 5）、维修电解电容：变频空调器中有大容量的电解电容，最大为2000-4500uF，即使切断电源仍然会残留有充电电荷，所以对电解电容器要先用烙铁、插头等物体充分释放残留电荷。电荷放尽以后，用指针式万用表RX10K档检测，指针应是指到0，然后慢慢退到∞，否则电解电容器损坏。</p> <p> 6）、维修传感器：如果空调器出现频率无法升降与保护性关机等故障，应首先考虑检查传感器，大多数传感器可以从插座上拔下，从外表上即可以判断是否损害、断裂、脱胶。用手或温水加热，用万用表RX100档测其阻值，看它的阻值是否变化，无变化则可以判定传感器损坏。</p> <p>本文地址：https://www.ktwxx.com/wenda/10811.html</p> <p><strong>TAG标签：
