Description
The utility model relates to a kind of A.C. welder, especially the annular core energy-saving electric welding machine.
Compare with the utility model, comparatively approaching in the prior art is Chinese patent " efficient ac arc wedling machine ", the patent No. 94244660.7.This machine is provided with closed circuit annular core in cabinet, primary coil is wrapped on the full annular iron core in the form of a ring equably, secondary coil is wrapped in the primary coil outer surface more equably, one termination electrode holders of this secondary coil, another termination bonding, it is by handling the centre tap of shunting switch conversion primary coil, regulate operating current, to reach the purpose that reduces power consumption, steady operation electric arc.But also there is following some deficiency in the design of this machine structure or structure: the one, though the intrinsic permeance of silicon steel sheet determine that it makes annular core can closed circuit magnetic conduction, but can not directed magnetic conduction, be that no-load current and no-load loss are bigger: the 2nd, its annular core is formed by stacking after being washed into annular by the multi-disc silicon steel sheet, the interior circle of silicon steel sheet and leftover pieces are nearly more than 50%, the square-section of annular core is long-pending bigger in addition, corresponding coil turn is many, so cost of manufacture is higher; The 3rd, its secondary coil is wrapped in the primary coil outer surface, and the operating current of generation is bigger, has both used shunting switch to switch adjusting, also is difficult to turn down electric current (according to minimum current greater than 150A), and the scope of promptly regulating electric current is restricted.In addition, the cross section of its annular core is a rectangle, and the flat type copper wire of dimension level coil is thicker, so the right angle transition is difficult for when twining.
The purpose of this utility model provides a kind of improved A.C. welder, annular core energy-saving electric welding machine especially, and it can reduce manufacturing cost and use cost effectively, can regulate little electric current again.
The purpose of this utility model is achieved in that
Adopt the silicon steel sheet billot to coil and be overlapped into annular core, primary coil and secondary coil insulated separately separate and be wrapped on the annular core equably, one reactance coil is wrapped in the primary coil outer surface, one end of reactance coil and secondary coil one end be connected into a contact, the other end therewith contact can connect bonding respectively, the other end of secondary coil then connects electrode holders.
Described annular core can be selected for use the silicon steel sheet billot of 9 following odd numbers to coil poststack to become cross section to be four jiaos the trapezoidal of 0～3 ladder mouth respectively arranged.
Adopt section superimposed or ring is radially superimposed when coiling the above superimposed annular core of silicon steel sheet with 1.
When the tapping point of the centre tap of handling shunting switch conversion primary coil or conversion bonding, the scalable size of current, make electric welding machine efficient, energy-conservation, stably work.
The utility model is overlapped into closed circuit annular core because adopt the silicon steel sheet billot to coil, so high, the directed magnetic conductivity of utilization rate of raw materials is good, magnetic flux is big; Owing to insulating separately with secondary coil, separates by primary coil simultaneously, even on annular core, so its no-load loss is little, can effectively regulate little operating current: again because primary coil is outer around reactance coil, reactance coil two ends (connecing) but some tap bonding, so electric current is steady can make big current work state the time; Because four jiaos of annular core rectangular cross section can have the ladder mouth, institute is so that wound coil in addition.
The concrete structure of utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is according to the annular core energy-saving electric welding machine structural representation that the utility model proposes.
Fig. 2 is according to the superimposed schematic diagram of annular core energy-saving electric welding machine annular core A-A section section that the utility model proposes.
Fig. 3 is according to the radially superimposed schematic diagram of annular core energy-saving electric welding machine annular core A-A section ring that the utility model proposes.
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the electric welding machine that the utility model proposes.
Referring to Fig. 1, this electric welding machine includes middlebrow cabinet, so omit in the drawings.Cabinet is built-in with annular core (3), primary coil (2) and secondary coil (4) insulate separately and separate and be wrapped in equably on the annular core (3), and the end and secondary coil (4) one ends that are wrapped in the reactance coil (7) of primary coil (2) outer surface are connected into a contact (A
2), the other end (A
1) contact (A therewith
2But) tap bonding (6), the other end (B) of secondary coil (4) connects electrode holders (5).Primary coil (2) is provided with three centre taps, and (c) and shunting switch K, primary coil one end (o) connects zero-power line for a, b, and (a, b c) are fixed on the shunting switch K other end (d) successively, and shunting switch K connects power firestreak with three centre taps.Annular core (3) is illustrated oval ring, also can be annular, and the former is suitable for the electric welding machine of various power, and the latter is suitable for low power electric welding machine.Referring to Fig. 2, be a kind of cross sectional representation of annular core A-A section, it is four jiaos of rectangles that a ladder mouth (9) is respectively arranged, and the periphery is a circle insulating barrier (8), and one wide two narrow three to coil the silicon steel sheet section superimposed.Referring to Fig. 3, also be a kind of truncation surface schematic diagram of annular core A-A section, diagram and Fig. 2 with, just one wide two narrow three to coil silicon steel sheet radially superimposed for ring.(cross section is four jiaos respectively has a ladder mouth (9) electric welding machine to be fabricated to example: primary coil (2) is totally 279 circles with the oval ring iron core of rated power 10KW, secondary coil (4) is totally 59 circles, reactance coil (2) totally 10 circles, oval ring outer minor axis 20mm, internal moment axle 8mm, outer major axis 30mm, interior major axis 18mm, silicon steel sheet billot with a wide 40mm and two each wide 10mm is coiled, section is superimposed or it is radially superimposed to coil, encircle with the silicon steel sheet billot of a wide 60mm and two each wide 40mm, just becomes through heat treatment.Handle shunting switch K, conversion primary coil (2) one ends (d) and centre tap (a, b during work, c) with being connected of power firestreak, just can regulate operating current, when being adjusted to big electric current, reactance coil (7) promptly works, and bonding (6) meets reactance coil (7) one end (A
