The WX1403 Charging Plum shaped Contact Pressure (Clamping Force) Measuring Instrument is suitable for measuring the contact pressure of high and low voltage isolating switches, plum shaped contacts, SF6 load switches, high voltage solid insulation cabinets, and low voltage drawer type switchgear main circuit connectors.
1. Overview
WX1403 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. The contact pressure of switch contacts is an important judgment parameter for the conductivity performance of the main circuit, and it is also an important influencing factor for whether the isolation contacts of the main circuit can withstand the impact current during operation and whether the temperature rise is qualified during full load operation. The variation of contact pressure of contacts is influenced by factors such as spring material and its processing technology, switch assembly accuracy, usage environment, load properties, and operating frequency. The influence of multiple factors. In order to ensure the long-term stable and reliable performance of switch contacts, it is necessary to regularly detect the contact pressure of the main circuit contacts.
