Device and method for testing tensile property of nonmetal grounding material of transformer substation

The invention relates to the technical field of electrical material testing, in particular to a tensile property testing device and method for a non-metal grounding material of a transformer substation, the tensile property testing device comprises a bottom plate, a fixing mechanism and a stretching mechanism, the bottom plate is connected with a supporting mechanism, the stretching mechanism comprises a supporting seat, and the supporting seat is connected with a reinforcing plate and a moving plate; a double-shaft motor is arranged on one side of the supporting seat; the device has the beneficial effects that a flexible graphite composite grounding cable body is clamped and fixed through a supporting mechanism and a fixing mechanism, then a gear disc is driven to synchronously rotate in the opposite direction under the action of a double-shaft motor, a bevel gear I, a bevel gear II and a rotating shaft, and finally, a movable plate moves in a reinforcing plate; the anti-slip clamping plate is driven to stre
