Recently, Baoguang completed the mechanical endurance verification on long-life vacuum interrupter of 1,500,000 times after running-in with a duration of 134 days, and the project has achieved remarkable results.

This project is for a key technical product set up by Baoguang at the beginning of the year. The project team built a workbench for long-life mechanical running-in in a very short time, and carried out in-plant mechanical endurance test and assessment on the product. After long-life verification of 1,500,000 times, the VI is still in good condition! The results fully verified that the design and manufacture of the VI and bellows completely meet the core technical indicators of long life.

In order to meet the requirement of high reliability and performance on the product, the project team started the project from its application, test condition, key parameters and key parts. After several times of scheme design and review, they completed the new product approval and the trial production of first batch of samples within one month. In order to ensure continuous test, they still conducted the test through remote video monitoring and holiday breaks. So that the project can pass the running-in test as soon as possible, and finally overcome all difficulties and achieve current major results.

Currently under the complex market situation, technological innovation is an important measure for enterprises to maintain their core competitiveness. Baoguang has focused on several technological breakthroughs in vacuum interrupter field this year, and successful research and development trial production have been reported frequently. The verification on long-life VI of 1,500,000 times will provide decisive support for the long-life operating conditions in domestic power system. Baoguang R&D team will continue to use this as an opportunity to contribute national manufacture and technological innovation strength to the final market transformation of the whole project!
