Abstract
The utility model relates to a multi-magnetic-path all-magnetic control electric welder transformer. The utility model is characterized in that a traditional quadrate main iron core with an interface is replaced by an annular main iron core without an interface, and a traditional cuboid translational movable iron core is replaced by a fan-shaped rotating movable iron core, so that the traditional methods of controlling voltage, reactance and current by a circuit are completely discarded, and accordingly, the voltage, the reactance and the current can be controlled completely by changing magnetic paths. The utility model has the advantages of reasonable design, good dropping characteristic, safe and convenient operation, simple structure, convenient maintenance, small size, light weight, low noise, long service life, low cost, small no-load current, energy saving and electricity saving; the utility model also has the advantages that no electronic element is used, but the utility model can be adjusted freely, and current can be controlled to small enough to be beneficial for welding thin material. The utility model has broad prospect to develop to various magnetic controlled voltage regulators.
Description
The utility model relates to a kind of dependence fully and becomes the ac arc welder (being called for short full magnetic control electric welding machine) that magnetic circuit comes regulation voltage, reactance and electric current.A new architecture that belongs to welding transformer.Have the desirable outer feature of falling suddenly, be specially adapted to the welding of thin material.
Existing moving-iron type ac arc welder, the way that changes floating voltage are to rely on the turn ratio that changes former and deputy winding.Change the way of reactance: the one, the number of turn of that part of winding of double as reactance coil in the change auxiliary winding; The 2nd, change the degree of depth that moving iron inserts " window ", with change secondary leakage field can what.
It is to realize by the connection that changes secondary terminal plate or with shift switch that older models changes turn ratio, often because of the tie point loose contact of the switching on damage of generating heat.The moving iron of translation will be handled with the special transmission mechanism of a cover, has increased parts and cost thus.Certain space be must leave between moving iron of translation and the main iron core, thereby the magnetic resistance and the work noise of leakage magnetic circuit increased.In order to guarantee enough leakage field magnetic circuit cross sections, moving iron will have enough big sheet wide and repeatedly thick, very huge to activate iron, and this huge moving iron is only just all utilized when requiring leakage field maximum, therefore welding machine is had to and increase weight, volume and cost, thus the small electrical welding machine is not used moving iron mostly.
Advanced electric welding machine comes pressure regulation, current limliting, technical sophistication, cost to improve with controllable silicon or with magnetic saturation device and inverter, and the welding technology institute that but is not the ordinary skill requirement is necessary.Magnetic saturation control technology itself is not a good method of utilizing ferromagnetic material economically yet.
Goal of the invention of the present utility model be exactly for the above-mentioned many shortcomings that overcome existing electric welding machine well-designed go out a kind of novel, technical scheme is rational, simple in structure, function admirable, easy to use, handling safety, volume is less, weight is light, cost is lower, noise is very little, energy saving, and is specially adapted to weld the electric welding machine of thin material.
The technical scheme of the full magnetic control electric welding machine of the utility model is as shown in drawings:
(1) non-magnetic conduction supporting tooth, (2) primary winding, (3) fan-shaped moving iron core, (4) annular main iron core, (5) auxiliary winding among the figure.Along some magnetic tooth and line embedding grooves of drawing are arranged, primary winding is entangled in an anodontia side separately in the annular main core, and auxiliary winding is distributed in each groove of tooth one side.Fan-shaped moving iron can be used for rotating.
Operation principle is as follows: fan-shaped moving iron position is as when figure, the ferromagnetism leakage field magnetic circuit that provides for auxiliary winding is maximum, thereby auxiliary winding leakage reactance maximum, and each circle of auxiliary winding is a part by main flux all, the passive iron of another part has been shunted, and output voltage, electric current are all minimum at this moment.Moving iron turns over certain angle clockwise, is then reduced by the number of turn of " shunt magnetic ", do not increased by the number of turn of " shunt magnetic ", thereby output voltage and all correspondingly increases of electric current.Moving iron turns over the angle difference, and output voltage is also different with electric current.
The advantage of the technical program is:
(1) given up fully to rely on and changed the old technical scheme that circuit comes regulation voltage, reactance, electric current, thus the introducing of electric welding machine, lead-out wire once connect just need not again moving, also without shift switch.
(2) replace the square shape main core with annular main iron core, magnetic circuit shortens 1/5th, and does not have interface and can reduce magnetic resistance, thereby has improved the efficient of electric welding machine, has reduced no-load current.
(3) the moving iron of fan-shaped rotary type replaces the moving iron of cuboid translation, makes the electric welding machine compact conformation, performance optimization, and volume reduces, and cost reduces, energy-conservation economize on electricity, noise lowers.
(4) electric current can be transferred to very for a short time, is specially adapted to weld thin material, and can develop into magnetic controlled voltage regulator and satisfy extensive needs.
Claims (3)
1. full magnetic control electric welding machine of multipath magnetic circuit, mainly formed by annular main iron core, fan-shaped moving iron core and former and deputy winding, fan-shaped moving iron core can rotate different angles in annular main iron core, it is characterized in that: primary winding (2) auxiliary winding (5) is respectively in the teeth groove of annular main iron core (4); The interior garden cambered surface of the outer garden cambered surface of fan-shaped moving iron core (3) and annular main iron core (4) increment is a pair of smooth mating surface of same tapering, its not self-locking of tapering; Can draw back the gap during adjusting and rotate, the outer garden cambered surface of fan-shaped moving iron core (3) is communicated with all or part of magnetic tooth that draws on the interior edge of annular main iron core (4), thereby can change the size of welding current, voltage simultaneously.
