Magnet valve controlled arc suppression coil

The utility model discloses a magnet valve controlled arc suppression coil which is a conjugated triplex column iron core formed by an upper main iron core column and a lower main iron core column and two upper side column iron cores and two lower side column iron cores, wherein the main iron core columns are respectively wound with a winding; two controlled silicons are connected to the taps of the upper coil and the lower coil; and the iron cores of the two main iron core columns are provided with a plurality of stages of sections. The direct current control current is provided after self-coupling transformation of voltages at two ends of the arc suppression coil and silicon controlled rectifier, an independent high-capacity direct current excitation source is not needed, the voltage current characteristic of the arc suppression coil is ensured to have good linearity, as the iron cores of the upper column and the lower column are provided with a plurality of stages of saturable small sections, the two side column iron cores are not saturable, thus leading the harmonic wave of the magnet valve controlled arc suppression coil to be minimum, improving the compensatory accuracy and effectiveness, and having fast response speed, extremely high reliability, wide stepless capacity adjusting range, low noise, durability, free of maintenance, compact overall structure, novel and beautiful appearance, and convenient and fast wiring.
