The invention discloses a
plasma generator with a middle section structure, which comprises a front
electrode, a middle section, a rear
electrode, a main gas inlet
cyclone gas ring and an auxiliary gas inlet
cyclone gas ring. One end of the front
electrode is connected with one end of the auxiliary gas inlet
cyclone gas ring, and the other end of the auxiliary gas inlet cyclone gas ring is connected with one end of the middle section; the other end of the middle section is connected with one end of the main air inlet cyclone gas ring, and the other end of the main air inlet cyclone gas ring is connected with one end of the rear electrode. The unique middle section structural design is adopted, the middle section and the front electrode do not need to be insulated,
jumping from the middle section of the arc root of the
electric arc to the front electrode is achieved through the exquisite design of the middle section structure, the pneumatic organization and the main air inlet and auxiliary air inlet
airflow distribution technology, and compared with a multi-stage middle section, the structure is simple, and large
voltage and large power can be stably output without adding a large-current arc jump device.
