Electrode Optimum Design and Experimental Study of Triggering Feature of Field Distortion Spark Switch |
| |
| Abstract: | The field distortionspark gap used as the switch in pulse generator for desulphurization of flue gases isstudied. Various electrode shapes are discussed, and Borda is selected. Using the rotatingellipse approximation method to optimize the electrode shape, an experimental study hasbeen carried out on the triggering feature and discharge distribution property of theoptimum designed switch. As a result the switch can be triggered reliably by relative lowtriggering pulse as well as the uniform discharge distribution has been acquired, whichcan prolong the life level of switch. |
