The invention provides an isolation switch contact pressure measuring device which comprises a base. Two sides of the base are respectively equipped with a positioning assembly for fixing the moving contact of an isolation switch to be detected and a telescoping drive assembly for driving simulated static contact and moving contact to connect or disconnect. The action end of the telescoping drive assembly is connected to one end of a guide rod. The middle part of the base is equipped with a guide seat. The guide rod goes through the guide hole of the guide seat. The other end of the guide rod is equipped with a simulated static contact bracket. The simulated static contact is fixed by the simulated static contact bracket. The simulated static contact is equipped with a pressure sensor for detecting the pressure when the simulated static contact and moving contact are closed and connected. The invention provides isolation switch contact pressure measuring device with high accuracy and good practicality.
Description
technical field [0001] The invention relates to the field of isolating switches, in particular to a device for measuring contact pressure of isolating switches. Background technique [0002] Contact pressure is an important indicator of the quality of the isolating switch, which affects the closing and opening speed, bounce and loop resistance of the switch, as well as the power requirement of the operating mechanism. At present, there is no professional contact pressure (clamping force) detection method. Only by measuring the circuit resistance of the switch to determine the clamping force requirement, but there are many factors that affect the circuit resistance, and it cannot be accurately judged. Contents of the invention [0003] In order to overcome the disadvantages of low accuracy and poor practicability of the existing isolating switch contact pressure measuring method, the present invention provides a isolating switch contact pressure measuring device with high a...
