The device comprises a base, wherein a fixed seat and a driving mechanism are oppositely arranged on the base; a damping device is arranged between the fixed seat and the driving mechanism; the damping device is close to the fixed seat; a first connecting rod is arrangedon the damping device; the driving mechanism is provided with a second connecting rod, the first connecting rod and the second connecting rod are respectively used for connecting two ends of the to-be-tested insulating pull rod; the driving mechanism is further connected with a control processing display system, and the control processing display system controls the driving mechanism to drive theto-be-tested insulating pull rod to axially simulate opening and closing reciprocating motion.

Description

technical field [0001] The invention belongs to the field of high-voltage equipment testing, and in particular relates to a device for testing the overall stability of insulating pull rods for high-voltage circuit breakers. Background technique [0002] High-voltage circuit breakers are widely used in power grid equipment, and play an important role in the power grid system because of their control and cut-off functions in high-voltage circuits. Insulation tie rod is an important part of high-voltage circuit breaker, which plays an important role in power transmission and insulation isolation in the circuit breaker. Since the moving contact part of the circuit breaker and the operating mechanism need to conduct precise movement through transmission components such as insulating rods to ensure the accurate movement of the contacts, so as to achieve reliable movement during the arc extinguishing process. Therefore, the quality of the insulating rod directly affects the reliab...
