Abstract
The combination type power source is comprised of two or more sets of plasma cutting machine power sources including constant-current voltage transforming circuit, rectifier circuit, filter circuit, high-frequency high-voltage circuit, program control circuit, non-transfer arc circuit, air supply circuit and cooling circuit, it features wide application range and low energy consumption.
Description
The invention belongs to cutter sweep, particularly relate to a kind of plasma cutter.
CUT is because of it has plasma arc temperature height, cutting speed height, characteristics have obtained extensive use to the performance impact that is cut workpiece is little etc., but in, the price height, the volume heaviness that exist of high-power CUT, be suitable for shortcomings such as working range is narrow, when particularly cutting thin plate and middle plate, energy consumption is big, efficient is low, slot is of poor quality.
The purpose of this invention is to provide a kind of combination march-past power supply apparatus for plasma cutter, this plant energy consumption is low, and the scope of application is big.
The present invention realizes by following technical scheme: it comprises power supply A and B and a combined controller of at least two cover unit CUTs, combined controller is made of terminals and switch, the unit plasma generator is received in the power supply A of unit CUT and the output of B respectively separately, perhaps and be connected to combined controller, high-power plasma generator is received in the output of combined controller.
The power supply of unit CUT comprises the constant current transforming circuit, rectification circuit, filter circuit, high-frequency and high-voltage generator, the untransferable arc circuit, programme control circut, the air feed circuit, cooling circuit, rectification circuit is delivered in the output of constant current transforming circuit, rectification circuit be transported to filter circuit, after coming out one after another, the output of filter circuit and high-frequency and high-voltage generator is added to the input of combined controller, perhaps directly be added to the electrode of unit plasma generator, another input of combined controller is received in the output of untransferable arc circuit, perhaps directly receive the nozzle of unit plasma generator, the signal of programme control circut output is added to the constant current transforming circuit respectively, high-frequency and high-voltage generator, untransferable arc circuit and air feed circuit, the untransferable arc circuit is made of resistance and switch serial connection, air feed electric routing switch device and the magnetic valve that controlled by switching device constitute, and cooling circuit comprises switching device and is subjected to the motor of switching device control.
The present invention is with two covers or overlap unit CUT power supply circuits and combined controller constitutes together more, both can be used for big or middle power CUT, can be used for two or many small-power CUTs again simultaneously, the scope of application is big, and can cut down the consumption of energy, improve cut quality, raising utilization rate of equipment and installations.
Fig. 1 is a combination march-past power supply apparatus for plasma cutter block diagram.
Embodiment:
Three-phase alternating current is added to three-phase bridge rectifier circuit after the constant-current transformer transformation, DC voltage after the rectification carries out the positive pole that superposition is added to the unit plasma cutting-torch again with the output of high-frequency and high-voltage generator after filter circuit filtering, one of untransferable arc circuit terminates to the nozzle of unit plasma cutting-torch, and public end of another termination power and the workpiece that is cut.The program control signal that programme control circut produces is controlled constant-current transformer, high-frequency and high-voltage generator, untransferable arc circuit and air feed circuit respectively.The output of unit power supply is received the corresponding output end of combined controller, through being received respectively by output on electrode, nozzle and the control element of high-power plasma generator after the parallel connection.Cooling circuit provides plasma generator electrode interior cooling device operation power and program.
