The energy storage motor for ZN12 mechanism will store energy immediately after being closed in use. That is to say, the spring energy is required when the circuit breaker is closed and opened, and the closing is provided by the closing spring, and the opening is provided by the opening spring. The energy source of the closing spring is provided by the energy storage motor, which is why the energy is stored immediately after closing.
The source of the energy of the energy storage motor for ZN12 mechanism opening spring is mainly provided by the closing spring when the circuit breaker is closed. The opening spring is connected to the main rotating shaft of the circuit breaker through the connecting rod. When the closing is closed, the closing spring releases the energy, which drives the main shaft of the circuit breaker to rotate, the main shaft drives the contact of the circuit breaker to close, and the main shaft rotates while the extension opens. The spring stores energy for the opening spring.
It can be seen that the energy storage motor for ZN12 mechanism is in operation, and its opening spring energy is completed synchronously with the circuit breaker closing, ensuring that the circuit breaker can be reliably opened as long as it is in the closing state. That is to say, the closing needs to close the energy of the spring, and the opening requires the energy of the opening spring.
