The invention relates to a spring operating mechanism which belongs to the technical field of electric transmission and transformation. The spring operating mechanism comprises a stand plate, a spring cylinder, a ratchet wheel, a guide wheel, a connecting rod, a support plate, a guide seat and a switching-on spring, wherein a switching-off spring is arranged in the switching-on spring; the upper end of the switching-off spring is fixed in the spring cylinder; the lower end of the switching-off spring is connected with a spring seat; the lower end of the spring seat is simultaneously articulated with a bridge-shaped connecting plate and an output crank arm; the lower end of the bridge-shaped connecting plate is articulated with the front end of a drive crank arm; a switching-off roller anda press rod are arranged on the drive crank arm; the front end of the press rod is in contact with a front roller on a large switching-off pawl; and a rear roller on the large switching-off pawl is in contact with a front locking rod of a small switching-off pawl. The spring operating mechanism reduces the volume of the operating mechanism by coaxially distributing the switching-off spring and the switching-on spring and has the advantages of short switching-off and switching-on time, stable mechanical characteristic, high reliability, small size, and the like.
Description
technical field [0001] The invention belongs to the technical field of power transmission and transformation equipment, in particular to a spring operating mechanism. Background technique [0002] The operating mechanism is the main equipment for high-voltage power transmission and transformation, and is an important part of the high-voltage circuit breaker. The opening and closing operations of the high-voltage circuit breaker are realized by the operating mechanism. The operating mechanism of high-voltage circuit breaker is mainly divided into hydraulic operating mechanism and spring operating mechanism. The hydraulic operating mechanism has the advantages of short opening and closing time, stable opening and closing time, etc. Oil and other shortcomings; because the spring operating mechanism does not have oil leakage problems, compared with the hydraulic operating mechanism, it has the characteristics of lower cost, simple structure, and long service life. It will be wid...
