Energy storage switch operation method does not store energy how to do?

In addition to spring energy storage and hydraulic energy storage, there is also compressed air energy storage. The advantage of spring energy storage is that after energy storage, even if the loss of external power supply, can rely on the energy storage spring tripped open the circuit breaker, of course, can not be in the case of loss of power to let the circuit breaker close. The disadvantage is that the spring force is transmitted very quickly, the impact on the circuit breaker operating mechanism is relatively large. Due to process improvements, the electric operating mechanism is easy to break this disadvantage has now basically no. Hydraulic energy storage energy transfer is relatively slow, the impact of the circuit breaker operating mechanism is slightly smaller. The disadvantage is that it is easy to leak oil and cause the loss of pressure. The advantage of compressed air energy storage is that the loss of power in the case, only by compressed air tank of compressed air, can be several times the closing and tripping operation, which is very important for some of the external power supply to start the factory, once the loss of power, other switches can not be closed, but compressed air energy storage of the circuit breaker is still able to act. We survived an embarrassment in Bangladesh with this type of switch. But this type of energy storage also has the problem of leakage, and there is also the problem of the moisture in the air freezing in the winter and blocking the air ducts
