  • Patent number: 10297402
    Abstract: The present invention discloses a magnetic pulse inducted transfer-type DC circuit breaker. The DC circuit breaker comprises a main current circuit and a transfer current circuit, the main current circuit comprising a combination of a fast mechanical switch or a mechanical switch with a power electronic device; the transfer current circuit comprises an arrester and a mutual inductor. The voltage generated through a mutual inductor may directly transfer current to the arrestor, thereby eliminating a process of transfer of the current to the capacitor or a power electronic device; it has a high current limiting or breaking speed, with a stability far superior to traditional technologies. The isolation between the capacitance charging unit and the DC system significantly reduces the voltage level and size of the charging unit, and enhances action reliability.

  • Patent number: 10283302
    Abstract: A electrical distribution system has been developed to provide a remote central control point for individual circuits, and methods have been developed for retrofitting it to existing service panels or installing it into new service panels. This system provides a power circuit monitoring and control system that fits inside standard residential service panels, both new and retrofitted panels. The entire system can be retrofitted into existing breaker panel systems without the need of removing any permanent structure such as a wall. During this retrofit process, the panel cover on the existing distribution panel is first removed after the power to it is disconnected. The old breaker assembly is removed from the panel, and a circuit controller is then installed in the now available space within the panel. A new service panel enclosure with a circuit breaker assembly is installed directly over top of the enclosure.
