Abstract

The embodiment of the invention discloses a three-phase filter inductor and an arc welding machine. The three-phase filter inductor comprises a fixed iron core, a movable iron core group, an inductance coil group and a movable assembly, the inductance coil group is fixed on the fixed iron core; the inductance coil group comprises three inductance coils; at least part of the movable iron core groupis positioned in the inductance coil group; the movable iron core group comprises three iron core columns, and each iron core column corresponds to one inductance coil; and the movable assembly is connected with the movable iron core groups and used for adjusting the distance between the movable iron core groups and the fixed iron core. According to the embodiment of the invention, on the basis of simplifying the structure and reducing the cost, the current wide-range adjustment of the three-phase filter inductor is realized.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of inductance, in particular to a three-phase filter inductance and an arc welding machine. Background technique [0002] Arc welding machine, also known as arc welding transformer, is a special transformer that converts the alternating current of network voltage into low-voltage alternating current suitable for arc welding. DC arc welding machine, also known as DC arc welding power supply, is composed of DC arc welding power supply, welding tongs and other welding accessories. However, the inductance adjustment of the existing DC arc welding machine has the problems of complex structure and high cost. Contents of the invention [0003] The embodiment of the present invention provides a three-phase filter inductor and an arc welding machine, so as to realize wide-range adjustment of the current of the three-phase filter inductor on the basis of simplifying the structure and reducing ...
