摘要

A short circuit protector will quickly switch off power in case of an overload or short circuit fault in order to quickly isolate or eliminate the fault. This research uses the contradictions matrix of the TRIZ innovation theory and 40 innovation principles to innovate and improve the product. The improved short circuit protection employs an optical coupler for detection, and the control circuit is triggered synchronously at the moment when a short circuit happens so as to cut off the power and sound a buzzer alarm. The response time is 14 milliseconds, which is faster than the response time (0.1 seconds) of tripping a fuse circuit breaker so as to achieve circuit protection.
