南京电脑控制仪器厂生产的 ZDZ—3型自增遥控多功能经络导平治疗仪,其工作电压有六组:5V、18V、10V、20V、40V、60V,它们是由电源变压器厂提供的。故障现象:接通电源后,仪器面板上的各指示灯亮,但无电压输出。经检查,发现线路(见图1)中电源变压器的次线圈12、13组线圈烧断。对此类故障,重绕或更换变压器都很麻烦,因为该变压器共有8组线圈,体积又较大。
ZDZ-3-type remote control multi-function Meridian-guided therapeutic apparatus manufactured by Nanjing Computer Control Instrument Factory has six groups of working voltage: 5V, 18V, 10V, 20V, 40V and 60V. They are provided by power transformer factory. Symptom: After the power is turned on, the indicator light on the instrument panel is on, but no voltage output. After examination, found that the line (see Figure 1) in the secondary coil power transformer 12, 13 sets of coils blown. For such failures, rewinding or replacement of the transformer is very troublesome, because the transformer a total of 8 sets of coils, the volume is larger.
