<p><P>PROBLEM TO BE SOLVED: To automatically inhibit a leakage current of a rectifier circuit and an exciting current during suspension of a charging generator, and to prevent discharge of a storage battery. <P>SOLUTION: The number of revolutions of the charging generator driven by a motor is always detected by a wind pressure sensor, and a closing signal is provided to an electromagnetic contactor at the predetermined number of revolutions or more. An opening signal is provided to the contactor at the predetermined number of revolutions or less, then outputs of the storage battery and the charging generator are automatically opened and closed by the electromagnetic contactor, by which the exciting current of the charging generator and the leakage current of the rectifier circuit are inhibited which are caused at the suspension of the charging generator or at a low rotating speed in which the generated output is not obtained, and the discharge of the storage battery is prevented. There exists an advantage that the storage battery is connected only when such the number of revolutions is obtained as is larger than the number of revolutions at which the generator can output, and the discharge of the storage battery is prevented without consuming power at all times like a semiconductor sensor by physically detecting the number of revolutions of the charging generator. Moreover, there exists a greatest feature that power consumption during monitoring by the sensor is zero, for the wind pressure sensor physically detects. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
