DEVICE FOR VOLTAGE SUPPLY OF NETS OF HIGH-VOLTAGE INSECT KILLER Russian patent published in 1995 - IPC

FIELD: agriculture. SUBSTANCE: an insect flying through nets of high-voltage insect killer is killed by an electric discharge. Simultaneously, a sharp surge of current occurs in primary circuit of transformer supplying these nets because the load in transformer secondary circuit at the moment is close to zero. Cutting a nonlinear resistance into transformer primary circuit reduces current therein because said nonlinear resistance grows with the increased current flowing therethrough. This rules out the generation of an electric arc between nets. EFFECT: improved design. 1 dwg
