Capacitively Coupled Static Eliminator With High Voltage Shield

US Patent:
4216518, Aug 5, 1980
Filed:
Aug 1, 1978
Appl. No.:
5/930028
Inventors:
Dolph Simons - Philadelphia PA
Assignee:
The Simco Company, Inc. - Lansdale PA
International Classification:
H01T 1904
US Classification:
361213
Abstract:
In a shockless type static eliminator having pointed discharge electrodes capacitively coupled to the high voltage side of an A. C. power source and a grounded conductive member or housing adjacently spaced from the discharge points, the improvement comprising the interposing of a high voltage shield about the capacitor plates from which the discharge points project in order to minimize the capacitance between such capacitor plates and ground. The reduced plate-to-ground capacitance, C. sub. g, enables a greater portion of the supply voltage, V. sub. s, to be applied to the discharge points without increasing the discharge electrode-to-high voltage capacitance, C. sub. p, thereby permitting the use of smaller and less expensive power supply and static bar constructions.
