In the electromagnet power supply circuit disclosed in No. 126828 (Japanese Unexamined Patent Publication No. 51-65360), a cutoff switch is connected between the rectifier bridge circuit and the power supply terminal connected to the AC power supply, and the auxiliary winding is It is connected between both terminals of a series circuit consisting of a cutoff switch and a bridge circuit. In such an electromagnet power supply circuit, the electromagnet necessary to attract the armature during the retraction operation is provided by the rectified current flowing through the main winding. However, when the electromagnet drives a switch and the switching operation is performed at a high speed of, for example, 1200 times per hour, there is a risk that the main winding will heat up.

抑制出来るのである。 The illustrated power supply circuit includes a rectifying bridge circuit connected between AC supply terminals A 1 and A 2 so as to supply AC power, and consisting of diodes D 1 to D 4 . An auxiliary winding, that is, a holding winding, is connected between the connection point of diodes D 1 and D 2 and terminal A 2 .
M2 is connected. Also, diodes D 2 , D 3
A cutoff switch C2 is connected between the connection point of and terminal A2 . Switch C1 is an electromagnetic overall control switch. The lead-in winding M 1 is connected as a diagonal branch between the connection points of the diodes D 1 , D 2 and D 3 , D 4 . During the retraction operation, the retraction operation switch C2 is closed. At this time, a full-wave rectified current flows through the main winding M1 . Furthermore, a half-wave rectified current flows through the diode D1 to the subwinding M2 . At this time, diode D2 acts as a free-wheel diode. This half-wave rectified current contributes to an approximately 10% increase in the ampere-turns required to attract the movable magnetic circuit portion of the electromagnet by appropriately setting the winding directions of the main and auxiliary windings. This point is different from the circuit disclosed in Japanese Patent Application No. 50-126828, in which the auxiliary winding is connected between the so-called AC terminals of the bridge circuit. Furthermore, the interaction between the main and sub windings is significantly reduced compared to conventional circuits, and as a result, fluctuations in the excitation current in the main winding during the pull-in operation can be suppressed, improving efficiency and reducing the Temperature rise can also be suppressed.

Note that the subwinding M2 may be connected between the connection point of the diodes D3 and D4 and the terminal A2 . In other words, the subwinding M2 is connected so as to bypass the cutoff switch and the one diode connected thereto.
