Title: John F Burr: Innovator in Overcurrent Protection Technology
Introduction
John F Burr is a notable inventor based in Pittsburgh, PA, with a significant contribution to the field of electrical engineering. He holds a total of four patents, showcasing his innovative spirit and technical expertise. His work primarily focuses on enhancing safety and efficiency in electrical systems.
Latest Patents
One of Burr's latest patents is a junction box designed for overcurrent protection. This apparatus is particularly useful in underground mining operations, where it connects a trolley wire conveying direct current power to an electrically powered vehicle. The system includes a shunt connected in series with a power source, allowing the current drawn by the trolley wire to pass through a circuit breaker and the shunt. The shunt generates a voltage input signal proportional to the current drawn, which is then compared to a reference signal by a solid-state comparator device. If the current exceeds the permitted level, the comparator device terminates the output signal to the trip circuit, de-energizing the circuit breaker and ensuring safety by opening the contacts to stop current flow.
Career Highlights
Burr is currently employed at Consolidation Coal Company, where he applies his expertise in electrical systems to improve safety measures in mining operations. His innovative designs have made a significant impact on the industry, particularly in enhancing the reliability of electrical equipment used in hazardous environments.
Collaborations
