In response to the current maintenance status of the power supply system, this portable charging contact pressure measuring instrument (also known as the overall plum blossom contact clamping force tester) can display the contact pressure of each pair of contact fingers in real time by simply inserting the sensor of the device's simulated contact into the contact position of each pair of contact fingers. Effectively solved a major problem in measuring finger pressure. This portable charging contact pressure measuring instrument (integral plum blossom contact clamping force tester) can also be used for plum blossom contact manufacturers to inspect the contact finger pressure.

The contact pressure measuring instrument is suitable for measuring the contact pressure of high and low voltage isolating switches, plum blossom contacts, SF6 load switches, high voltage solid insulation cabinets, and low voltage drawer type switchgear main circuit connectors. Compared with existing indirect measurement methods, this measuring instrument has the advantages of intuitive and accurate measurement, no need for AC power supply during measurement, and easy and fast operation. The measuring instrument is widely used in the manufacturing plants of the above-mentioned switch contacts, high and low voltage switchgear production plants, as well as various high and low voltage switches and switchgear operation sites.
