Research and Development Technique of Low-Voltage Arc Quenching System Based on Modern Measuring and Testing Approaches

A research and developed technique of low-voltage arc quenching system based on modern measuring and testing approaches was proposed. This technique takes synthetic circuit as testing source instead of traditional short circuit test station with demountable quenching chamber to do the interrupting test together with modern measuring and testing approaches to get the key information of interrupting performance. This allows the development process to be speeded up, significant optimization of the chamber configuration and geometry, considerably reduction of development cost, uprading quality of design and saving the electrical power. Some real examples for this technique applied in low-voltage electrical apparatus were introduced in this paper.
