Abstract

See full text

The present disclosure relates to direct current arc extinguishing circuit and apparatus. The direct current arc extinguishing circuit and apparatus are suitable for quickly extinguishing arc of mechanical contacts such as mechanical switches, where a mechanical switch requiring arc extinguishing is connected with a load in series. It includes a voltage detection switch and a capacitor, wherein the voltage detection switch is connected with the capacitor. During the breaking of the mechanical switch, the capacitor forms a discharge loop by the voltage detection switch and the load, and is used for breaking arc extinguishing of the mechanical switch. The present disclosure is reasonable in design and has the advantages of low cost and high arc extinguishing speed.
