Testing And Verification Of The Fusing Characteristics Of Drop-out Fuses
Date: | Read: 2
An adjustable test power supply is used, set at twice the rated current, and the fuse breaking time must be controlled within 120 seconds. This test verifies the response speed and accuracy of the drop out fuse fuse under overload conditions, ensuring it can promptly disconnect the circuit within the set time to prevent damage to electrical equipment or wiring due to overload.
During the test, it is also necessary to observe whether the fuse's operation is smooth, and whether there are excessive delays or failures to blow, in order to further adjust design parameters or manufacturing processes to ensure its long-term operational stability and safety.
