Abstract

This utility model discloses a testing device for the mechanical characteristics and circuit resistance of a lower disconnect switch, relating to the field of lower disconnect switch testing technology. The device includes a frame; a support assembly is provided inside the frame; the support assembly includes a fixed plate fixedly installed with the frame; two symmetrical transverse slide rails are provided on the fixed plate; a carrier plate is movably mounted on the transverse slide rails via sliders; limit blocks are fixedly installed at the four corners of the carrier plate; double-round-head through slots are provided on both the carrier plate and the fixed plate; multiple limit blocks are installed in conjunction with the lower disconnect switch; a robot gripper places the lower disconnect switch into the limit blocks at the top of the carrier plate, effectively ensuring the accuracy of the lower disconnect switch's position during placement. After placement, the robot sends a signal for the next action, and the lower disconnect switch is manually pushed to one side of the housing to achieve a dynamic sealing connection between the lower disconnect switch and the break-in control mechanism.
