Insulated pull rod testing device

Abstract

The utility model relates to machine parts testing technical field, concretely relates to an insulating pull rod testing device. The insulating pull rod testing device includes the test platform, and the test platform is installed with the pull rod support frame, load mechanism and drive mechanism, and the pull rod support frame is equipped with the guide channel for with the both ends of insulating pull rod guide cooperation, and the drive mechanism is used for with the one end transmission connection of insulating pull rod and drives insulating pull rod to move in the guide channel along its axial direction, and the load mechanism is used for with the other end transmission connection of insulating pull rod and cooperates drive mechanism to make insulating pull rod move when bears axial load. Simulate the stress state of actual insulating pull rod in actual high -voltage switch, reach the purpose of testing insulating pull rod axial bearing capacity, do not have to with the dismounting of other components or parts of switch, can improve the test efficiency of insulating pull rod mechanical strength, do not influence the life test of high -voltage switch.
