Abstract
The present invention is a kind of transformer type arc welder with tapping, and this device has a square shape iron core, is wound with primary and secondary coil on two side columns.By the bind mode of one group of activity contact change secondary windings, make full use of the idle part of coil, strengthen leakage field, reduce the copper iron ratio of transformer.Be a kind of efficient height, Arc Welding Power that cost is low.
Description
The present invention relates to a kind of Arc Welding Power, particularly the method with the conversion coil tap changes leakage field, regulates the transformer type arc welder with tapping of welding current.
The arc-welding machine of tapped transformer formula has a square shape iron core, and one is the elementary post that is wound with based on primary coil in two side columns, and another is the secondary post that is wound with based on secondary coil.The primary coil separated into two parts respectively has tap, is enclosed within respectively on elementary post and the secondary post.A change-over switch that is serially connected in the primary coil branch road is regulated welding current by the conversion tap.Secondary coil is separated into two parts also, and a winding is arranged on elementary post, and two windings are arranged on the secondary post.Secondary windings has two kinds of bind modes: when using big welding current, with winding positive polarity series connection on a winding on the secondary post and the elementary post; When using little welding current, with two winding positive polaritys series connection on the secondary post.
There are two problems in this arc-welding machine: the one, and idle idle winding is many, has increased amount of copper consuming.The 2nd, leakage reactance is little, thereby coil turn is many, makes transformer copper iron than big, and efficient is low, cost is high.Therefore this class welding machine only suits to make the specification of little electric current, low cyclic duration factor.
Be sort this problem out, 1988 the 1st phases, the 11 pages of propositions of " electric welding machine " magazine are connected in series a part of winding in the primary coil reversed polarity, to increase leakage reactance, to reduce electric current.The method of playing a reversed role has two kinds: a kind of is to play a reversed role when specially being equipped with a winding for little electric current gear, and its shortcoming is to have increased new idle winding when other electric current gears.Another kind is to use the idle winding of part, but elementary effective turn is reduced, and exciting curent increases, and the corresponding reduction of leakage reactance has weakened the effect that leakage reactance is increased because of playing a reversed role.And and be subjected to the restriction of core sataration, can participate in the number of turn of playing a reversed role can not be many, make total effect little.
The objective of the invention is to provide a kind of copper iron than little, the transformer type arc welder with tapping that cost is low.
The object of the present invention is achieved like this: by one group of activity contact, when using big electric current with secondary post on the secondary windings of two equal turn numbers connect with secondary windings positive polarity on utmost point And connection back and the elementary post, reduced idle winding; When using little electric current with secondary post on two secondary windings positive polaritys series connection backs connect with secondary windings reversed polarity on the elementary post, utilize idle winding to play a reversed role, increase leakage reactance, minimizing welding current.
The voltage that the voltage that the present invention is offset because of the reversed polarity series connection increases from secondary windings in series on the secondary post, ratio is big, thereby the leakage reactance increase is big, and welding current is little.Make primary coil can adopt the less number of turn, add and reduced idle winding, transformer copper iron is reduced than reduction, efficient raising, cost.
The concrete structure of invention is provided by following embodiment and accompanying drawing.
Fig. 1 is the electric hookup of the transformer type arc welder with tapping of proposition according to the present invention.
Fig. 2 is the installation diagram of the activity contact of a kind of embodiment of proposition according to the present invention.
