Abstract
High-voltage current-limiting fuses have been extensively employed for the protection of transformer circuits, motor circuits, capacitor circuits and voltage transformer circuits, with excellent protective performance achieved. Under different circuit conditions, high-voltage current-limiting fuses are required to withstand various transient impacts without incurring partial damage or deterioration, such as transformer inrush current, motor starting current, capacitor charging current, or the excitation current of voltage transformers. During the design process, high-voltage current-limiting fuses need to be verified through a substantial number of tests to confirm that their withstand performance meets the application requirements. In combination with IEC standards, GB standards and nuclear power standards, this paper summarizes and compares the withstand performance requirements of high-voltage current-limiting fuses, with a focus on the differences between the specific requirements for power grid applications and nuclear power plant applications. Meanwhile, a technical analysis is conducted on the verification conditions for the withstand performance of high-voltage current-limiting fuses, providing a technical foundation for the implementation of this test.
