The basic operation principle of the spring operating mechanism is independent, and the energy storage mechanism is generally only supplied to the closing spring, and the trip spring is generally accommodated by the circuit breaker. There is a switching energy contact in series in the closing circuit, that is, the switch is not stored. However, there is no in series with a switching without the energy storage contacts in the width circuit. Therefore, even if the switch is not energy, you can also jump. (Note: The switching of the switch is not stored here that the hierarchy spring is not accumulated, while the hierarchy spring is not stored.).

When the circuit breaker is turned off, the hierarchy spring is still not necessarily stored, while the closing spring is accommodated. When the closing is closed, the hierarchy spring releases energy, and the hierarchy is accomplished. To ensure that the switch can be jumped when the switch is closed. When the hierarchy spring is released (the switch is just closed), the motor starts to the closing spring energy, this approximately ten seconds, at this time, it is fault, because the springs are accommodated, so you can jump.

This also illustrates that the switch can jump immediately when the hand is in the fault, but this kind of jump cannot be again compiled immediately (it needs to be different from the heavy closing), because the closing is still not energy, etc. Electricity. If the switch is originally closed, the shutter spring and the hierarchy spring of the switch are accommodated. When there is a fault, the hierarchy spring releases the energy shift. In addition to about 1 second, (due to the closed spring accommodation) the shutter is released. At the end of the closet, the hierarchy spring has been stored, but the closing spring has not been accomplished.

If this closing is over, the switch can be jumped immediately because the hierarchy spring ends. But after the jump is open, I can't immediately immediately immediately, it is necessary to wait until the end of the shutdown spring energy, it takes 30 seconds after 30 seconds, but the actual situation will wait until the accident is completed, can re-trial again )
