Surge arrester with reinforced varistor and winding layer
The patent US11996218B2 describes a surge arrester designed to enhance electrical protection through a unique structural configuration. The device comprises two opposing end fittings that house a stack of one or more varistors, which are essential for voltage regulation. A key feature is the winding layer, made from resin-impregnated fiberglass thread, that wraps around the varistors. This winding layer can be either partly or fully closed, providing structural integrity and insulation. Additionally, a reinforcement element, characterized by an open cross winding, maintains tension between the end fittings, ensuring stability and durability. The design also allows for specific cross-sectional thickness ratios between the reinforcement element and the winding layer, enhancing the overall strength of the surge arrester.
Further specifications include the use of a cationically crosslinking epoxy resin within the winding layer, which may contain UV or thermal initiators to improve adhesion and performance. The patent outlines that the winding layer can cover the entire outer surface of the varistors, and it also describes the presence of open rhombic areas within the cross winding, which are strategically designed with angles ranging from 20 to 160 degrees. The surge arrester may also feature a silicone outer housing, providing additional environmental protection. The method for producing this surge arrester involves wrapping the stack with the fiberglass thread while employing a specific axial and rotational movement to create the desired winding structure. This innovative design aims to improve the reliability and efficiency of surge arresters in electrical systems.
