Problems solved by technology

The dispersive characteristics of the action time of the electromagnetic system exist both for AC electromagnetic appliances and for DC electromagnetic appliances, which makes it difficult to control electromagnetic appliances, and the influence is more obvious for electromagnetic circuit breakers that require fast action.
Although the time of the microprocessor control system is within the microsecond level, the dispersion of the action time of the mechanism often leads to control failure, and, with the frequent operation of the switching device, the wear of the contact system, the aging of the mechanism, etc. Will cause the action time to change
[0009] (3) Narrow working voltage range
[0011] (5) There is hysteresis eddy current loss in the magnetic circuit
For AC electromagnetic appliances, the alternating magnetic field leads to iron loss in the magnetic circuit. Although the iron core structure of silicon steel sheet is used, there is still a large loss, and it brings certain difficulties to product design and magnetic circuit analysis.

Description

technical field [0001] The invention relates to the field of intelligent control of equipment, in particular to a novel intelligent electronic coil. Background technique [0002] Electromagnetic appliances are devices that use electromagnetic systems for energy conversion. Electromagnetic systems are mainly composed of magnetic mechanisms and coils. The excitation coil is energized to magnetize the magnetic system to generate electromagnetic attraction to attract the armature and make it move to do mechanical work, so as to achieve the predetermined purpose. It is one aspect of the energy conversion of the electromagnetic system to absorb energy from the power supply through the coil and output mechanical work through the movement of the armature; to input the electromagnetic signal through the coil and output the command through the mechanical movement of the armature is another aspect of the control function of the electromagnetic system aspect. The electromagnetic syste...
