Abstract
The invention discloses an energy-saving and non-energy saving switching circuit on a condition of no power off. The switching circuit comprises an energy-saving bypass control loop and a circuit breaker control loop, wherein the energy-saving bypass control loop is connected with the circuit breaker control loop. The switching circuit has the advantages that switching directly from bypass to energy saving or from energy saving to bypass can be achieved within 0.02 second on the condition of no power off by using the switching circuit if another loop is needed to be switched for use during fault occurring in an energy-saving loop state or a bypass running state by a user, and a power utilization device cannot be cut off when the switching is achieved within a sine wave period.
