为安全起见,最好接入假负载对电源进行检修。但应注意的是,在检测中,不可人为地或因某种检测中的意外,使电源电路元件之间发生短路,这样会导致大面积的元器件的损坏,使故障扩大化。如拔下插接件时,输出电压正常,说明负载有短路性故障,如仍无输出,故障在电源电路(包括各电压输出端的滤波电容中某一个有严重漏电或短路);如拔下插接件,输出电压正常,但接入电路输出电压下降,说明电源带载能力下降或负载有漏电元器件;如拔下插接件或不拔下插接件检测时,某一绕组上输出电压为
For safety reasons, it is best to access the dummy load to repair the power supply. However, it should be noted that short circuit between power circuit components may occur during detection due to accidental or accidental detection. This will cause damage to large-scale components and enlarge the fault. If the plug is unplugged, the output voltage is normal, indicating that the load has a short-circuit fault. If there is still no output, the fault is caused by a serious leakage or short circuit in the power circuit (including one of the filter capacitors at each voltage output terminal) Connector, the output voltage is normal, but the output voltage of the access circuit is decreased, indicating that the power supply with a drop in load capacity or with leakage components; such as unplug the plug connector or unplug the connector detection, a winding output voltage for
