Title: Weie Chen: Innovator in Overvoltage Protection Technologies

Introduction

Weie Chen is a notable inventor based in Shanghai, China, recognized for his contributions to overvoltage protection technologies. With a total of two patents to his name, Chen has made significant advancements in the field of electrical safety, particularly for direct current (DC) systems.

Latest Patents

Chen's latest patents include a disconnection and switch-over device for overvoltage protection, specifically designed for DC systems. This invention features an arresting element and a thermal cut-off point that is integrated into the electrical interconnect path. The thermal cut-off point consists of a movable mechanically prestressed conductor element that transitions from a first position to a second position during a cut-off event. When the second position is reached, an electrical switch-over to a safety device is activated. The design ensures that a complete electrical cut-off occurs only when the movable conductor element surpasses the second position and reaches a third position.

Another significant patent by Chen is an overvoltage protection arrangement that incorporates multiple planar varistors arranged on one side of an N-cornered supporting plate. This arrangement includes at least one gas arrester and a thermal disconnection device that is thermally connected to the varistors. The components are encased in an outer housing, with electrical connection means provided for soldering to a printed circuit board. The varistors are organized in a parallel stack, separated by insulating partition walls that facilitate the thermal disconnection process.
