Abstract: Aiming at the existing surge protector device (SPD) structure characteristic and reliability problem, this article proposed a new structure for improvement and presented the improved design scheme for separator, low temperature material and inserting and pulling structure. The test result shows that the improved structure has solved the operating imbalance problem of surge protector device separator in theory, which enhances thermal stability of SPD product, reinforces capability of short-circuit short time endurance, reducing the failure, and improves convenience of changing SPD module.
Key words: surge protector device; reliability; separator; thermal stability; inserting and pulling force
