The utility model discloses a novel 35kV and below CT type spring operating mechanism vacuum circuit breaker. With the novel 35kV and below CT type spring operating mechanism vacuum circuit breaker adopted, problems such as burnout of a motor, a coil and a switch which are caused by mutual independence of two loops in the prior art can be solved. The novel 35kV and below CT type spring operating mechanism vacuum circuit breaker is characterized in that a travel switch is replaced by a high-power travel switch; the high-power travel switch is utilized to control a motor; and an energy storage motor loop and a switch-on coil control loop are made to be mutually locked; and therefore, the burnout of the motor, the travel switch and a switch-on coil can be prevented. The novel 35kV and below CT type spring operating mechanism vacuum circuit breaker has the advantages of reasonable structure, convenient installation, safe use, low failure rate and the like, and can be widely applied to transformer substations of which voltage level ranges from 10 to 35kV.
