ELECTROMAGNET BOOSTER CONTROL DEVICE Russian patent published in 2000 - IPC

Abstract RU 2153726 C1

FIELD: electromagnetic operating mechanisms for switching equipment. SUBSTANCE: device that has single-phase diode bridge rectifier with series-connected break contact, controlled electromagnet, and electromagnet coil inserted between its output terminals, as well as other coil whose first lead is connected to common point of connection of break contact and electromagnet coil is provided, in addition, with diode connected between second coil lead and one of input terminals of bridge rectifier; additional diode is connected through other coil and break contact to two diodes of bridge rectifier by means of like-polarity electrode. Other coil may be that of other electromagnetic operating mechanism. Device is suitable for use in automatic control equipment supplied with booster voltage from alternating-voltage sources. EFFECT: improved reliability, reduced power requirement and cost of device. 3 cl, 4 dwg
