Background

The quality of the main circuit connector of the switch cabinet in the operation and maintenance work of the daily switch cabinet plays a significant role in safe and reliable operation of the switch cabinet, and whether the contact pressure of the contact of the main circuit connector is enough is an important index of the quality of the connector, which determines whether the temperature rise is qualified when the drawer is in full-load operation and whether the impact of the starting current of the motor can be resisted when the motor is started, particularly when the motor is frequently started. The measurement and control of the plum blossom contact pressure are very important links for ensuring the quality of the main loop connector. However, at present, no instrument for directly measuring the pressure of the contact is available, so that the pressure of the contact of the connector cannot be directly measured.

At present, the industry adopts a 'plug-in method', namely a spring scale is used for measuring the force when a movable plug-in unit is inserted into and pulled out of a static socket, so as to indirectly judge whether the contact pressure is enough. Because the plugging force is related to the contact shape, the surface finish, the friction coefficient of the contact material, the spring pressure and other factors, the plugging force is not in one-to-one correspondence with the contact pressure; this method is not effective in obtaining a true value of the contact pressure.
