Abstract
The invention relates to the technical field of circuit breakers, in particular to an energy-saving miniature circuit breaker, and overcomes the defects of incomplete arc division and arc extinction and big influence on service life of the circuit breaker. The energy-saving miniature circuit breaker comprising an arc extinction system and a tripping mechanism is characterized in that the arc extinction system is composed of an arc striking corner and an arc striking plate; the arc connection end of the arc striking plate is an arc bend, and the middle of the arc striking plate is provided with a convex surface; a main spring of the tripping mechanism is a main tension spring and located at the center of the tripping mechanism, one end of the main tension spring is a hole-shaped semicircle while the other end is in the shape of a double-right-angle bent hook and hinged to an internal groove in a lever, and the tension spring is fixed through two positioning bosses on two sides of the internal groove. The tripping mechanism is flexible and reliable in action, and the energy-saving miniature circuit breaker is long in service life, small in internal resistance and low in power consumption, material saving, energy saving and environment friendly as an arc partition wall and upper and lower magnetic conductive sheets are unarranged, and faster in arc striking, smoother in arc migration and higher in performance due to the design of the arc extinction system.
