<p>PURPOSE:To simplify the structure of a voltage detecting circuit and to improve the reliability in the detection of a voltage by combining an AC type low voltage relay and a DC time limiting relay. CONSTITUTION:An AC type low voltage relay ACLVR1 and ACLVR2 are respectively connected to the output sides of generators G1, G2 of respective motor generators. The contacts of the AC type relay ACLVR1, ACLVR2 are respectively connected in series with the DC type relays GVTR1, GVTR2, and the contacts of the relays GVTR1, GVTR2 are respectively connected in series with a DC type low voltage relay MGLVR. In this manner, the low voltage detection output can be detected by the AC type relay, and sufficient time limit can be provided in a low voltage detection signal from the DC relay fed through the DC relay.</p> |
