Latest Patents
One of Lars Banghammar's latest patents is a DC switching device. This device includes a plurality of arc-extinguishing chambers and a series of contacting units that are conductively connected. Each contacting unit features a stationary contact and a movable contact, which can shift between a rest position and a working position. An air gap is created between the contacts when the movable contact is moved to the rest position. The chambers enclose the contacting units and contain a splitter plate unit designed to split and cool any arc that occurs in the air gap. Additionally, the chambers are equipped with a permanent magnet that generates a magnetic field between the contacting unit and the splitter plate unit. The splitter plates are made of non-ferromagnetic material, while the chambers' splitter plates are constructed from ferromagnetic material.
Another significant invention by Banghammar is a device for current limitation and protection against short-circuit. This invention aims to enhance safety and efficiency in electrical systems.
