Abstract

The invention discloses a modular spring actuator closing cam tripping device which is characterized in that the device comprises a manual closing mechanism (10) arranged on a right side plate (11) of an actuator, the manual closing mechanism (10) is equipped with a closing push rod (12), the closing push rod (12) directly faces the vertical side of an inverted L-shaped energy storage pawl (7), the end of the horizontal side of the energy storage pawl (7) is an arc head, the arc head contacts a roller (3), the roller (3) is located on the flange of a cam (8), an energy storage shaft (6) passes through the center of the cam (8), and the middle of the energy storage shaft (6) is sleeved with a shaft sleeve (5). The modular spring actuator closing cam tripping device provided by the invention has a simple structure, reduces the closing resistance, has parts not easy to wear, has a long service life, and increases the reliability of energy storage and closing tripping.

Description

technical field [0001] The invention relates to a closing cam release device of a modular spring operating mechanism, which belongs to the technical field of high-voltage switchgear. Background technique [0002] In the existing spring operating mechanism closing cam release device, the closing detent and the cam are generally in rigid contact. After many times of closing, the closing detent and the cam will be severely worn, and the service life is short. The reliability and the reliability of closing and tripping are poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a modular spring operating mechanism closing cam with simple structure, reduced closing resistance, less wear and tear of parts, long service life, increased energy storage and reliability of closing and tripping trip device. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the pres...
