Embodiment Construction

[0016] The prior art is used for reference, the original electromagnet core is replaced by a cylindrical permanent magnet 1, a cylindrical electromagnet 2 is set outside it, the outermost layer is a coil 3, and capacitors 4 and 5 are installed in appropriate positions. Such as figure 2 , Connect the capacitors 4 and 5 in series according to the polarity, and connect the common point to the lower end of the coil, and then connect to the terminal N. Connect the anode of the capacitor 4 to the static contact 7 of the normally closed moving contact through the diode 8, and connect the moving contact to the terminal L through the current limiting resistor 10; connect the cathode of the capacitor 5 to the static contact of the normally open moving contact through the diode 9 Point 6: Connect the "start" and "stop" signals between the other end of the coil and capacitors 4 and 5 respectively. When in use, just connect the power supply between L and N. In the state of working prepa...

Abstract

The invention relates to an electromagnetic system which is used for driving an armature-contact system in a relay (contactor). The electromagnetic system consists of a cylindrical permanent magnet, a cylindrical electromagnet, a coil and a capacitor. The capacitor is used for slowly charging to store energy and fast discharging so as to provide corresponding power for starting up and releasing, and the permanent magnet is used for keeping a continuous suction state, so that low-consumption and silent running of the relay (contactor) is realized. Additionally, the electromagnetic system has a simple control circuit, large input impedance, stable and reliable control manner, and no potential safety hazards, such as overheating and aging, overcurrent, action competition and the like, so that the work reliability and the service life of the system are enhanced, the technical performance, such as restitution coefficient and control coefficient and the like of the relay (contactor) is continuously improved, and the electromagnetic system is more convenient and more feasible.

Description

Technical field [0001] This case belongs to the electromagnetic system driving the armature-contact system in relays and contactors, which is the basic component of relays and contactors. Background technique [0002] With the process of industrialization and electrification, relays and contactors have emerged as the times require, and are widely used and constantly evolving. But in any case, it is inseparable from the electromagnetic system composed of electromagnet, armature and coil. The closing or connection of the armature-contact must rely on the electromagnetic torque generated by the coil to pass the current. In an automation system, hundreds of relays (contactors) are used, only a small part of the electrical power consumed by it is converted into mechanical force, and most of it is turned into heat, which heats up the system; and the AC electromagnetic system The humming sound often generated in the system not only wastes electric energy, pollutes the environment,...
