The invention discloses a centralized rectification variable-voltage distributed chopping pulse power supply. The centralized rectification variable-voltage distributed chopping pulse power supply ischaracterized by comprising a voltage regulating station and a plurality of station choppers, wherein the voltage regulating station is electrically connected with each station chopper through a two-phase power line or a copper plate, and the voltage regulating station is in communication connection with each station chopper through a signal line; and the voltage regulating station provides a low-voltage direct current to the station choppers, and the power of the multiple station choppers at the same time is lower than that of the voltage regulating station. The centralized rectification variable-voltage distributed chopping pulse power supply can be used for multi-station electric spark machining, electrolytic machining, electrochemical deburring and the like, and can provide pulse electricity with different parameters for each station. One voltage regulating station can provide the low-voltage direct current to the plurality of station choppers, a voltage regulating circuit with a large volume is placed into the voltage regulating station, the size of each station chopper is small, the direct current is changed into a pulse to be output to a machine tool, the station is convenient to install, and the plant space is saved.
Description
technical field [0001] The invention belongs to the field of electrical processing, and in particular relates to a centralized rectification and transformation distributed chopper pulse power supply. Background technique [0002] Special processing refers to those processing methods that do not belong to the category of traditional processing technology. It is different from traditional processing methods that use knives, abrasive tools, etc. to directly use mechanical energy to remove excess materials. Special processing is a new technology developed in recent decades. It is an important supplement and development to traditional processing methods. It is still being researched, developed and improved. Direct use of electrical energy, heat energy, sound energy, light energy, chemical energy and electrochemical energy, sometimes combined with mechanical energy to process workpieces. In special processing, electric spark machining and electrolytic machining, which mainly use ...
