High-power switching power supply test maintenance tool with overcurrent protection

The utility model relates to a high-power switching power supply test maintenance tool with overcurrent protection, which comprises a box body, an alternating-current voltage input connector arranged at the outer end of the box body, an alternating-current voltage output socket, an alternating-current voltmeter, an alternating-current voltmeter power supply connector, a switch, a bulb observation window and a lamp holder arranged in the box body, the bulb is located on the inner side of the bulb observation window. The AC voltage input connector is used for connecting a power supply, and the AC voltage output socket is used for connecting a to-be-tested product. According to the high-power switching power supply test maintenance tool with the overcurrent protection function, when the high-power switching power supply is maintained or subjected to parameter debugging, the explosion phenomenon caused by short circuit can be avoided, the safety coefficient of product maintenance and debugging is effectively impr
