Abstract
The utility model relates to a plasma generator comprising a cathode and an anode, which correspond with each other, wherein the cathode and the anode are connected with a rectifying power source and an arcing power source, a driving mechanism is connected on the cathode, the driving mechanism and the arcing power source are both connected with a controller, and the driving mechanism is also connected with a driving power source. When the contact-type arcing is performed, the controller controls the driving mechanism to move the cathode and the anode in the opposite direction until the cathode and the anode contact with each other and then separate from each other, thereby completing the contact-type arcing process; when the non-contact type arcing is performed, the controller controls the driving mechanism to move the cathode and the anode in the opposite direction; and when the distance between the cathode and the anode reaches a preset value, the arcing power source is started to arc between the cathode and the anode. By the adoption of the two mutually-complementary arcing modes, the stability and the reliability of arcing of the plasma generator are improved.
Description

When plasma generator 10 starts, under the control of controller (not shown), motor 11 drives 14 motions of negative electrodes 12 anode, and negative electrode 12 is with after anode 14 contacts, and negative electrode 12 and anode 14 conduct electricity, motor 11 drives negative electrode 12 again away from anode 14, up to setpoint distance, the gas ionization between negative electrode 12 and the anode 14, and produce gas discharge, negative electrode 12 and anode 14 are switched under the effect of dielectric gas, and plasma generator 10 is finished contact starting the arc process since then.
Though it is little, simple in structure and to the quality requirements of dielectric gas advantages of higher not that contact starting the arc mode has a starting the arc moment impact electric current, but also exist not enough, the main performance both ways: the one, in starting the arc process, the contact point of negative electrode 12 and anode 14 has damage, and is influential to electrode life; The 2nd, in starting the arc process, negative electrode 12 needs to move towards anode 14 earlier, retreats again, and starting the arc speed is slower.
Fig. 2 shows a kind of plasma generator that adopts contactless starting the arc mode, and plasma generator 20 comprises that negative electrode 21, positioning component 22, anode cooling water channel 23, anode 24, negative electrode cooling water channel 25 have reached arc power 26.
The anode 24 of plasma generator 20 fixedly installs, and inside is provided with and is used to circulate the anode cooling water channel 23 of water flowing with cooling anodes 24; Negative electrode 21 is fixed on the positioning component 22, and negative electrode 21 inside are provided with and are used to circulate the negative electrode cooling water channel 25 of water flowing with cooling negative electrode 21; Between negative electrode 21 and the anode 24 fixed interval (FI) is arranged; The positive and negative electrode that plays arc power 26 is connected with anode 24 with negative electrode 21 respectively.
When plasma generator 20 starts, under the control of controller (not shown), playing arc power 26 at first starts working, make the breakdown and ionization of gas between negative electrode 21 and the anode 24, negative electrode 21 and anode 24 are at dielectric gas and play arc power and be switched on and produce electric arc 26 times, and plasma generator 20 is finished contactless starting the arc process since then.
Though but noncontact starting the arc mode has the fast continuous several times starting of the starting the arc, no starting the arc contact point reaches and do not damage advantages such as negative electrode and anode, because of its quality requirements to dielectric gas higher, if dielectric gas is contaminated, the normally starting the arc.
As seen, plasma generator 10 still is that the starting the arc mode of plasma generator 20 all exists certain defective, is difficult to guarantee starting the arc process stabilization, efficient, can't adapt to practical application request.
