Wattless automatic compensation arrangement

Disclosed is a wattless automatic compensation arrangement, comprising a capacitor unit composed of a mutual inductor reactor integration device, a hurl-slices switch, and a parallel capacitor, wherein the mutual inductor reactor integration device, the hurl-slices switch, and the parallel capacitor are integrally packaged; the hurl-slices switch is a permanent magnetism hurl-slices switch; the permanent magnetism hurl-slices switch adopts the oil insulation packaging and is connected with the reactor in the mutual inductor reactor integration device; the mutual inductor in the mutual inductor reactor integration device is the Rogowski mutual inductor; and the Rogowski mutual inductor is designed into an opening type sampling current transformer. The wattless automatic compensation arrangement effectively reduces the size of the wattless automatic compensation arrangement, decreases the heating amount of the capacitor unit, and makes the hurl-slices switch have long service lifetime, thereby decreasing the failure rate of the wattless automatic compensation arrangement.
