Integrated test device for simulating DC system integrated type grounding fault

The invention belongs to the technical field of measurement and particularly relates to an integrated test device for simulating a DC system integrated type grounding fault. The device comprises a test control instrument and an integrated fault simulation generator. The test control instrument is connected to the integrated fault simulation generator and comprises a first shell which is internally provided with a control circuit board. The surface of the first shell is provided with a liquid crystal display screen, a setting panel, an operation button and a master switch. The control circuit board is connected to the liquid crystal display screen, the setting panel, the operation button and the master switch. The integrated fault simulation generator comprises a second shell which is provided with a pointer type voltage meter, a pointer type ammeter and a DC output device, the DC output device is connected to the pointer type voltage meter and the pointer type ammeter through a I section branch, and the DC ou
