Title: Alternating current switching device
Inventor: YIN XIANGYANG
IPC: H01H9/54
Filed: 2018-02-02
Abstract: The invention provides an alternating current switching device using two alternating current switches. At the respective two ends of alternating current switches are provided intersecting and connected current transfer circuits formed from two silicon-controlled rectifiers disposed in parallel and flowing in reversed directions, thus forming two current transfer circuits. By means of detecting the direction of an input voltage and the direction of an input current, one of the current transfer circuits can be selectively switched on, such that the direction of the input voltage and the input current can be reversed immediately, or, by means of the two silicon-controlled rectifiers in the current transfer circuit, an arc voltage across the two ends of the alternating current switch can be clamped to an input voltage. The addition of a current transfer circuit to each of the two alternating current switches enables full realization of energy recovery without being limited by the direction of the voltage and current at the time of a fault. When either of the two alternating current switches is disconnected, the current flows via the current transfer circuit without generating an electric arc at the contacts of the alternating current switch. The silicon-controlled rectifiers automatically perform switching-off without generating an electric arc, enabling a fast breaking response speed of the alternating current switch.
