Abstract
The utility model relates to a multiple energy source ac/dc two-purpose electric welding machine which is suitable for construction occasions with or without an electric network such as mines, bridges, railways, highways, oil wells, construction sites, farms, etc. The aim of the utility model is to provide a low power consumption, multi-energy (electric network, diesel engines, hydraulic turbines, etc.), and multipurpose ac/dc two-purpose electric welding machine. Two groups of star-connected three-phase windings are added on the stator. The utility model has the advantages of wide application range, small power consumption, high efficiency, and multifunction. The utility model can be directly used for ac or dc electric welding, and can be used for providing a 15 kw domestic power supply source to small mountain villages.
Description
The utility model relates to welding equipment, is applicable to that there is electrical network on mine, bridge, railway, highway, oil well, construction site, farm etc. or does not have used electric welding machine under the electrical network construction occasion.
Commercially available electric welding machine adopts the electrical network electric energy to convert low-voltage and high-current output to mostly, exchanges electric welding, direct-current electric welding, submerged-arc welding, falling property gas shielded arc welding and the required power supplys of technology such as plasma welding and cutting to provide.Do not have the suitable direct current electric welding equipment to use and there is the electrical network occasion, and have only mutually electricity and be inconvenient to turn round at no three phase mains place three phase electric machine.
The utility model purpose is to provide the multiduty alternating current-direct current of low-power consumption various energy resources (electrical network, diesel engine, the hydraulic turbine etc.) to weld dual-purpose electric welding machine.
The utility model purpose is achieved in that
A kind of multipotency source alternating current-direct current welds dual-purpose electric welding machine, comprise rotor and stator, it is characterized in that on described stator increasing by three phase windings of two groups of Y-connections, wherein connect the rectifier bridge of silicon diode between one group of three winding, two end points of rectifier bridge output are two deliveries of direct-current electric welding; At three phase windings of another group Y-connection of stator, common point is made center line, and three-way group the other end is made triple line A, B, C, D, and the three-phase of forming three-phase four-wire system inputs or outputs.
In conjunction with the accompanying drawings, further specify the utility model content.
Fig. 1 the utility model structure chart.
Among the figure:
D1-D6, diode L0-L2, Y-connection winding
A, B, C, N, triple line and center line AW, AC arc soldering tip
CW, direct current soldering tip ES, collector ring VR, variable resistor
Fig. 1 is the utility model structure chart.Frame of broken lines institute coil element is invention of the present utility model.In the drawings, generator unit stator is represented in outer garden, and generator amature is represented in interior garden, and ES represents it is the collector ring of magnet exciting coil; L0 is the auxiliary winding that extracts exciting current, and D7-D12 is a diode, and it connects into rectifier bridge, uses for magnet exciting coil.L1 is three windings of Y-connection, and connecting silicon diode D1-D6 between this three winding becomes rectifier bridge, and output two end points of rectifier bridge are two output points of direct-current electric welding, about 75 volts of its output dc voltage, and one of them end connects ground wire.L2 is another three winding of Y-connection, and its common node is made center line, and three-winding other three end points are respectively that A, B, C three-phase input or output a little.This A, B, C and N line can connect 380 volts interchange three phase electric machine.All windings are all on stator.
The utility model advantage:
1, be widely used, energy consumption is little, efficient is high;
2, a tractor serves several purposes can be directly used in interchange or direct-current electric welding;
3, use the electrical network three-phase alternating-current supply, can drive novel electricity generator, the output AC/DC Arc Welding Power.
4, drive with the hydraulic turbine, can be the household electricity power supply that little mountain village provides 15KW.
Embodiment 1
In the bridge construction building site, existing device is that the 50KW diesel generating set drives a dc welding machine, separate unit fuel consumption 5kg/ hour;
This novel device is the 15KW generating set, drives with the HP diesel engine, and during welding, separate unit fuel consumption 3kg/ hour, separate unit can be saved 2kg/ hour oil mass.
Embodiment 2
With 380 volts of civil power inputs, its A, B, C, N connect three phase electric machine, and three phase electric machine runs well.
Embodiment 3
Drive with the hydraulic turbine, can be the abundant little mountain village of waterpower resourses 15KW life and production electricity consumption are provided.
