Fault Analysis and Elimination of External Power Supply System of a Equipment
In the process of power supply guarantee, undervoltage alarm often occurs in the external power supply system of a equipment, which leads to the failure of normal power supply. Through analyzing the field situation, ana-lyzing the fault causes, and locating the fault point according to the working principle of the equipment, the fault is fi-nally successfully eliminated. In the process of troubleshooting, in order to realize the normal operation of the external power supply system of the device, the transmission system fault, circuit system fault, and electrical component fault are tested in batches to verify the fault cause, and the fault is finally confirmed as the undervoltage of the external power supply system. In actual operation, the fault causes are sorted out and the tree diagram is established, the troubleshooting method is summarized, and the corresponding preventive measures are put forward, which provides a certain reference for ensuring the normal and stable operation of the external power supply system of the equipment.
