Description
Technical Field
[0001] The invention relates to the technical field of electric operating mechanisms, in particular to an energy storage type molded case circuit breaker electric operating mechanism. Background Art
[0002] With the continuous development of power systems, the operating requirements for circuit breakers are increasing day by day. The traditional manual operation method can no longer meet the automation needs of modern power systems. Therefore, the development of electric operating mechanisms has become the key to realizing remote control and automation of circuit breakers. The electric operating mechanism is driven by electricity and can quickly and accurately complete the opening and closing operations of the circuit breaker. Compared with manual operation, it greatly improves the operating efficiency. The electric operating mechanism reduces the safety hazards caused by manual operation and improves the overall safety of the power system. The development of energy storage technology provides a new source of power for the electric operating mechanism. Through the built-in energy storage module, the electric operating mechanism can provide the necessary operating energy in power outages or emergencies to ensure the reliable operation of the circuit breaker.
[0003] The housing of the electric operating mechanism of the molded case circuit breaker needs to have a clear mark, which is generally printed by hand-screen printing. As a traditional printing technology, manual screen printing has been used throughout history. It uses the screen as the base, and through the extrusion of the scraper, the ink is transferred to the substrate through the mesh of the graphic part to form the same graphic as the original. Due to the small number of printings and the large variety of varieties, manual screen printing is widely used due to its flexibility and strong adaptability.
[0004] According to the above-mentioned related technologies, the quality of manual silk screen printing depends largely on the technical level and experience of the operator. The difference in technical level between different operators may lead to unstable printing quality. This will cause the silk screen printing of the shell logo of the electric operating mechanism of the molded case circuit breaker to be sometimes deep and sometimes shallow, and it is impossible to grasp the clarity of the silk screen printing of the shell logo of the electric operating mechanism of the molded case circuit breaker.

The cylinder 14 pushes the slide 24 to slide to the bottom of the screen printing machine 35, and the slide 24 drives the sleeve body 26 to slide along the length direction of the track platform 21.
