Abstract

The invention relates to a testing device adopting a high-voltage medium-frequency power supply low-voltage circuit and a dummy load. The testing device comprises a touch screen, the high-voltage medium-frequency power supply low-voltage circuit, the dummy load and an oscilloscope, wherein the high-voltage medium-frequency power supply low-voltage circuit and the touch screen perform communication through a serial port; the touch screen serving as a human-computer interface is used for controlling the high-voltage medium-frequency power supply low-voltage circuit; the high-voltage medium-frequency power supply low-voltage circuit comprises a control circuit board, a mutual inductor and a low-voltage power circuit. The testing device is simple in structure, can effectively detect the work state of the high-voltage medium-frequency power supply low-voltage circuit to ensure normal work of the high-voltage medium-frequency power supply low-voltage circuit and lays a good foundation for following access of a high-voltage rectifier transformer for complete computer testing.

Description

technical field [0001] The invention relates to a dummy load testing device, in particular to a dummy load testing device for a low-voltage circuit of a high-voltage intermediate frequency power supply. Background technique [0002] At present, in order to ensure the quality and performance of data center computer room delivery, many newly built computer rooms use dummy loads to simulate real server load heating and power consumption to test the availability of the entire computer room system. This process is called computer room comprehensive testing. The available data center computer rooms basically adopt the dual bus mode of dual power supply. Under normal operating conditions, the dual power supplies in the data center computer room each bear 50% of the load in the computer room. Currently, the dummy load used for the comprehensive test of the computer room Both adopt single-channel power supply mode, so when testing dual-channel power supplies, only one power supply ca...
