Title: The Innovations of Robert H. Lechner
Introduction
Robert H. Lechner is an accomplished inventor based in Southampton, PA (US). He is known for his significant contributions to the field of electrical engineering, particularly in the development of automatic reclosing systems for direct current (D-C) feeder breakers. With a focus on enhancing the safety and efficiency of transit systems, Lechner has made a notable impact in his area of expertise.
Latest Patents
Lechner holds a patent for a "Voltage sensing and load measuring automatic reclosing system for D-C." This innovative system is designed for D-C feeder breakers in transit systems that utilize cars with chopper-type regulated power. The patent outlines a circuit that includes voltage-sensing and load-measuring circuits, which ensure that there is no short circuit on the respective feeder line before the circuit breaker can be closed. The system operates in two sequential modes: the voltage-sensing mode and the load-measuring mode. In the voltage-sensing mode, the system detects a voltage on the feeder circuit greater than a specified magnitude, prompting the closing of the feeder breaker. If no voltage is sensed, the system transitions to the load-measuring mode, where a current is injected into the feeder circuit. The resulting voltage drop is monitored, and if a sufficiently high voltage is produced, indicating that the feeder circuit is free of faults, the feeder breaker is closed.
