High-voltage AC current-limiting fuse has been used widely in distribution network

and is an important protective component to ensure safe operation of power system. Some high-voltage current-limiting fuses are installed with the strikers for indicating operation and driving other switching devices to open. The performance of the installed strikers is an important factor to ensure the correct coordination between fuses and switching devices in case of failure. It is therefore necessary to carry out research on the test technique of high-voltage AC current-limiting fuse strikers and analyze its feasible test verification method. In this paper

the research on operation test of the striker

including such contents as implementation of the operation test

measurement of released energy

measurement of the minimum withstanding force and measurement of duration of travel

is mainly performed through the research of performance verification and test method of high voltage AC limiting fuse and in combination with test requirement of the strikers in the standard

and both feasibility and rationality of the implementation of above research contents are proved by the test verification. The implementation method on performance test verification of high-voltage AC current-limiting fuse strikers proposed in this paper will be of great significance to the high-quality development of this kind of product and

at the same time

also provide help for reasonable selection of high-voltage current-limiting fuses for relevant switchgear.
