Abstract
PURPOSE: To enable prevention of such a phenomenon as the stoppage of an engine and the breaking of the circuit of the main electromotor at the time of the transitional change in normal operation by providing a release time element between a wind-velocity detecting switch and an auxiliary relay.
CONSTITUTION: The release time element 20 is inserted and connected between the wind-velocity detecting switch 7 and the auxiliary relay 18. By this, the operation of the auxiliary relay 18 is stopped only while the velocity of the wind decreases instantaneously. That is, even when the velocity of the wind comes to the level where the wind-velocity detecting switch 7 is operated by the sharp change of the rotational number of the engine, the auxiliary relay 18 is set not to operate for about 5W6sec by the work of the release time element 20. At this time, the transitional change of the rotational number of the engine wherein the velocity of the wind falls below a prescribed value continues only for about 2W3sec and it soon returns to the rotational number of idling. Thus, such a phenomenon as the stoppage of the engine and the breaking of the circuit of the main electromotor at the time of the transitional change can be prevented.
