1. Energy storage process
When the energy storage motor 14 is powered on, the motor drives the eccentric wheel to rotate. The roller 10 close to the eccentric wheel drives the arm 9 and the connecting plate 7 to swing, pushing the energy storage pawl 6 to swing, and the ratchet wheel 11 rotates. When the pin on the ratchet wheel 11 and the plate of the energy storage shaft sleeve 32 move together, the closing spring 21 hung on the energy storage shaft sleeve 32 is elongated. The energy storage shaft sleeve 32 is fixed by the positioning pin 13 to maintain the energy storage state. At the same time, the crank arm on the energy storage shaft sleeve 32 pushes the travel switch 5 to cut off the power supply of the energy storage motor 14, and the energy storage pawl is lifted to connect with the ratchet. Reliable detachment.
2. Closing operation process
When the mechanism receives the closing signal (the switch is off and the energy is stored), the iron core of the closing electromagnet 15 is sucked and moved downwards, pulling the positioning member 13 to rotate in a counterclockwise direction, releasing the energy storage maintenance and closing The spring 21 drives the energy storage sleeve 32 to rotate counterclockwise, and its cam presses the transmission sleeve 30 to drive the connecting plate 29 and the rocker arm 27 to move, so that the rocker arm 27 buckles the half shaft 25 and the mechanism is in the closed state. At this time, the interlocking device 28 locks the positioning member so that the positioning cow cannot rotate counterclockwise, achieving the purpose of mechanism linkage, and ensuring that the mechanism cannot be closed at the closing position.
3. Opening operation process
After the circuit breaker is closed, the opening electromagnet receives the signal, the iron core is closed, and the ejector rod in the opening release 19 moves upward, which causes the trip shaft 16 to rotate, drives the ejector rod 18 to move upward, and pushes the bent plate. 26 and drive the half shaft 25 to rotate in the counterclockwise direction. The half shaft 25 and the rocker arm 27 are tripped, and under the action of the opening spring, the circuit breaker completes the opening operation.
