| Popis: |
Life test of molded case circuit breakers (MCCB) on mechanical endurance test setup showed degradation in the functional deliverables of a MCCB, such as reset force and contact pressure. Degradation in functional deliverables affects the satisfactory working of the circuit breaker and decreases its reliability. Functional deliverables of a MCCB in development phase can be measured using two systems of measurement. A gage repeatability and reproducibility study using 2 operators, 5 parts and 3 trials was performed to select the best measurement system. MCCBs were then tested on a life cycle test setup, and the degradation in the deliverables was measured using the selected measurement system. These measured values were analyzed, and the circuit breaker reliability was then predicted using Minitab software. |
