Problems solved by technology

With this structure, due to the large diameter of the multi-core cable, the winding process on the magnetic ring is relatively difficult, and it is not suitable for mass production. In addition, the inter-turn voltage is very high, and the inter-turn insulation is easily damaged, and the insulation is difficult and difficult. Difficult to grasp, this is the main problem existing in the prior art

Embodiment Construction

[0009] In order to clearly illustrate the technical characteristics of this solution, the following describes this solution through a specific implementation and in conjunction with the accompanying drawings.

[0010] By attaching figure 1 It can be seen that the step-up transformer for arc welding of the argon arc welding machine of this scheme is mainly equipped with a contact Z1 and Z2 at both ends of a multi-core cable (2) as the secondary coil of the transformer. On the multi-core cable (2) between Z2, there are 2-5 sets of magnetic rings (3) composed of 2-5 identical magnetic rings (3). This specific embodiment consists of four identical magnetic rings (3). The ring (3) constitutes a set of four sets of magnetic rings (3), and each set of magnetic rings (3) is also wound with a single-core thin wire (1) a1a2, b1b2, c1c2 and d1d2, and each turn is thin The starting ends a1, b1, c1, and d1 of the wire (1) are connected, and the ends a2, b2, c2, and d2 of each turn of the thin...

Abstract

The invention provides a boost transformer for arc striking of an argon arc welding machine. The boost transformer provided by the scheme mainly comprises a magnetic ring and a multi-core cable and ischaracterized in that a connector Z1 and a connector Z2 are respectively arranged at two ends of the multi-core cable, two to five groups of magnetic rings sleeve the multi-core cable between the twoconnectors Z1 and Z2, a turns of fine wire is further wound around each group of magnetic ring, an initial end of each turns of wire is connected, a tail end of each turns of wire is used as a primary coil of the transformer, the multi-core cable is used as a secondary coil of the transformer, and each group of magnetic rings sleeving the multi-core cable is provided with two to five same magnetic rings.

Description

Technical field [0001] The invention relates to a transformer, in particular to a step-up transformer for arc ignition of an argon arc welding machine. Background technique [0002] In the prior art, the well-known technology is the step-up transformer currently used on argon arc welding machines. It is on a set of large magnetic rings, and a multi-core cable with a larger cross section is wound on the magnetic ring. As the secondary coil of the transformer, it is connected to the main circuit of the welding machine power supply. A thin wire is wound around the magnetic ring. As the primary coil of the transformer, it is connected to the high-frequency generator to form a primary and secondary ratio of 1:4 step-up transformer. With this structure, due to the large diameter of the multi-core cable, the winding process on the magnetic ring is difficult, and it is not suitable for mass production. In addition, the inter-turn voltage is very high, the inter-turn insulation is easily...
