| Abstract [eng] |
Comparison of the DC corona field in the system „wire-to-cylinder“ with the cylinders radius 2 times greater than the distance between electrodes and in the system „wire-to-plane“ with the same distance between electrodes is performed by using the Deutsch‘s– Popkov‘s method. The space charge of the „wire-to-cylinder“ system increases the field strength on the wire surface by 16 % and decreases it on the surface of cylinder by 69 %. Corresponding quantities of change of the field strength in „wire-to-plane“ system are 8 % and 54 %. Computed value of onset voltage for the system „wire-to-cylinder“ is 4.70 kV, the experimental one – 4.35 kV. Corresponding quantities for „wire-to-plane“ system are 4.55 kV and 4.10kV. Current of discharge for the system „wire-to-plane“ are greater by 25 % in comparison with the values of current for „wire-to-cylinder“ system in the range of voltages near the onset value. This difference is egual to 16 % in the range of voltages exceeding the onset value by 50 %. The DC corona field for the „wire-tocylinder“ system can‘t be changed by the field of the system „wire-to- plane“ for given values of geometric parameters without introducing the substantial errors. It may be done when the radius of cylinder exceed the distance between electrodes more than 10 times. |
