Abstract

The utility model relates to a pulse transformer for electronic welders, which is composed of a fixing seat (1), an iron core (2) and operating line packages, wherein the iron core (2) is a soft magnetic ferrite iron core or an amorphous alloy iron core; a primary operating line package and a secondary operating line package are copper plates (3). The utility model is mainly used in an intelligent electronic welder for electrical energy transformation, has the advantages of small size, light weight, little high frequency loss, almost no vortex and circumfluence loss, obvious energy saving effect and strong overload operating capability.

Description

The pulse transformer of electronic welding machine

Technical field

The utility model relates to a kind of high-frequency pulse transformer, particularly the pulse transformer of the electronic welding machine that uses on the smart electronics electric welding machine.

Background technology

Existing portable electric welding machine is to be made of pulse generating circuit and high-frequency pulse transformer mostly at present.High-frequency pulse transformer is made of the coil of E sections core and the coiling of paper bag flat type copper wire, the secondary low-voltage winding then is to adopt a copper cash several paralleled conductor to turn to, the weak point that has the distributed capacitance increased circuit and contact resistance etc., not only eddy current loss or circulation loss are big, and the high-frequency loss on the increase circuit, reduce operating efficiency, limited the complete permanent power output of transformer.

Summary of the invention

The purpose of this utility model is in order to overcome above-mentioned weak point, and provides a kind of high-frequency loss few, does not have eddy current, circulation loss substantially, and energy-saving effect is obvious, the pulse transformer of the electronic welding machine that the overburden serviceability is strong.

In order to solve above-mentioned task, solution of the present utility model is: a kind of pulse transformer of electronic welding machine, form by holder, iron core and active line bag, iron core has adopted soft magnetic ferrite iron core or amorphous alloy iron core as the high frequency transformer core material, the space is penetrated with first and second copper coin of coiling in iron core, the head of secondary copper coin, in, end respectively draws three copper bar electrodes, between the copper coin of coiling being superimposed between the position and copper coin around be provided with insulating material.

The utility model is owing to adopt above architecture advances, the winding of will working is reeled by copper coin, high-frequency loss is few, substantially there are not eddy current and circulation loss, fundamentally solved the problem of can not the be complete permanent power output of pulse transformer of electronic welding machine, satisfied the requirement of welding procedure to transformer, energy-saving effect is obvious, the overburden serviceability is strong, and noise is little.The utility model has alleviated the weight of electric welding machine owing to use the amorphous alloy iron core to dwindle the volume of electric welding machine as the high frequency transformer core material.
