Transient resistance temperature distortion characteristic test device for iron tower grounding device

The invention provides a transient resistance temperature distortion characteristic test device for an iron tower grounding device, and the test device sets a test soil temperature through an upper computer, and carries out the sufficient and uniform temperature control of the soil around the iron tower grounding device through the test device. After the actual test temperature meets the requirement, transient voltage is injected into the iron tower grounding device through a transient voltage injection device, and the amplitude of transient discharge current is obtained through measurement; the transient resistance temperature distortion characteristic of the iron tower grounding device is evaluated through the transient discharge current amplitude in combination with the actual test temperature; the test device can effectively simulate the distortion process of the resistance of the iron tower grounding device under the transient voltage at different soil temperatures, improves the test precision through su
