Background technology
The traditional electrical welding machine needs external AC, under the occasion that does not have civil power to support, uses very inconveniently, on construction site or ship, builds and waits when needing the use of welding occasion, often wants pull the wire to draw electricity, has great potential safety hazard.The use of traditional electrical welding machine is single, can only be used for welding, in the open air or some place constructions away from the signs of human habitation such as desert, must carry generator and electric welding machine simultaneously just can satisfy the demands, and the personnel that can cause bear a heavy burden too much, the wasting of resources etc.
The present invention proposes a kind of new type of digital Electricity generating welder, integrates the function of generator and electric welding machine, has realized the irrealizable function of traditional electrical welding machine and conventional electric generators.Reduced volume and weight greatly, helped carrying, and output voltage stabilization, output harmonic wave is low to can be used on any machinery equipment, in welding, also can use alternating current simultaneously.The output voltage quality of this number Electricity generating welder is higher than the output voltage quality of conventional electric generators.
Summary of the invention
The invention solves the key issue that runs in the application of traditional electrical welding machine, combine engine, generator; Power electronics; Automatically control, technical fields such as microelectronics integrate the function of generator and electric welding machine; Output AC electricity (220V, 50Hz) and direct-current arc realized the irrealizable function of traditional electrical welding machine and conventional electric generators simultaneously.
A kind of digital Electricity generating welder machine; Comprise: engine provides the power of generator; Three-phase permanent magnet electricity generator is contained on the engine output shaft and exports one group of three-phase intermediate frequency high-voltage signal; Three-phase intermediate frequency high-voltage signal connects generation one road DC high-voltage power supply on the three phase rectifier Voltage stabilizing module respectively; This DC high-voltage power supply shunting part exchanges modular converter (master section) through direct current and produces one road high-voltage AC signal, is the sine wave of 220V through output voltage after the effect of LC low pass filter; Another part of DC high-voltage power supply exchanges modular converter (electric welding machine part) through a direct current and produces one road high-voltage AC signal; High-voltage AC signal produces low-voltage ac signal through behind the high frequency transformer then; Produce low-voltage dc signal after the rectification of low-voltage ac signal process AC/DC rectification module, produce direct-current arc through the welding arc generator at last.
