The contact pressure measuring instrument | contact clamping force measuring instrument has four functions for manufacturers and operating units of Great Wall low-voltage drawer type switchgear:
1) Measuring contact pressure can be an important basis for selecting connector and switchgear suppliers;
2) Prevent inferior products with low or high contact pressure from flowing into the assembly or use site during the procurement process of connectors from switchgear manufacturers or spare parts from operating units;
3) During the use of the switchgear, due to various reasons, the contact pressure of the main circuit connectors will gradually decrease. The contact pressure detector can be used to regularly check whether the contact pressure of the connectors in operation is still within the allowable range, evaluate the stability of the contact pressure of the connectors, and then evaluate the quality of the connectors;
4) Assist in analyzing the causes of overheating or burning of connectors in the event of equipment abnormalities or accidents during the operation of low-voltage drawer type switchgear.

The low voltage drawer switch cabinet contact pressure measuring instrument can measure the low voltage drawer switch cabinets of brands such as ABB, Great Wall, Schneider, Dongfang Electric, Siemens, etc. that are circulating on the market,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 is influenced by various factors such as spring material and processing technology, switch assembly accuracy, usage environment, load properties, and operating frequency. 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.
