Embodiment approach

[0021] As a second embodiment of the present invention, such as image 3 As shown, it also includes a deceleration drive motor 8 and a circuit control switch group 9, the circuit control switch group 9 is connected to the deceleration drive motor 8, and the iron core valve armature 5 is movably connected to the deceleration drive motor 8 through a guide rail assembly. The reduction drive motor 8 is used to control the movement of the iron core valve armature 5 between the main iron core 1 and the slave iron core 2 . The line control switch group 9 controls the deceleration drive motor 8, thereby controlling the iron core valve armature 5 to move smoothly and gradually from the iron core 2, thereby reducing the reactance value and maintaining the starting current value set for starting. Such as Figure 4 As shown, the line control switch group controls the deceleration drive motor 8, the deceleration drive motor 8 can be set according to the time required for the actual start ...

Abstract

The invention relates to an electric reactor type soft starter for an iron core valve. Compared with the prior art, the defect that existing soft starter is easy to generate higher harmonic, poor in overload capacity and high in failure rate. The electric reactor type soft starter for the iron core valve provided by the invention comprises an armature (5) of the iron core valve, an electric reactor winding (3), a main iron core (1), an assistant iron core (2) and a short-circuit circular winding (4) winding on the iron core (2), wherein the electric reactor winding (3) winds the main iron core (1) and the assistant iron core (2), and the short-circuit circular winding (4) forms a coupling circuit with the electric reactor winding (3) through the iron core (2) and the armature (5) of the iron core valve. According to the invention, the starting characteristic of a motor is softened without waveform distortion and higher harmonic, and the soft starter is free from pollution to a power grid.

Description

technical field [0001] The invention relates to the technical field of soft starting, in particular to an iron core valve reactor type soft starting device. Background technique [0002] In construction, metallurgy, mining and other power industry fields, electrical equipment has been widely used. When the motor starts, the starting inrush current is very large. When the power capacity of the motor is large, it will cause interference to the power grid and other loads, and even endanger the safe operation of the power grid. In order to solve this problem, most of them use the method of soft start. However, the magnetic saturation controllable reactor soft start or electronic soft start currently in use generally adopts DC excitation or AC isolation self-excited reactor, and its execution unit uses high-power solid components such as RSC and RS, and its control circuit is complicated. , easy to generate high-order harmonics, poor overload capacity, high failure rate, and ce...
