TEST FIXTURE FOR POWER SWITCHING DEVICE

摘要

PURPOSE: An apparatus for testing a power switching device is provided to prevent the fracture of the device due to excessive tightening operation by monitoring the tightening value of the device using a meter. CONSTITUTION: A frame(10) forms an opening part at one side. Upper and lower electrodes(20, 30) are arranged in the frame, and a switching device is installed between the electrodes. A load cell is arranged in either of the upper electrode or the lower electrode to measure pressure applied to the switching device. A tightening screw(40) vertically applies pressure to the upper electrode through the frame.
