Outdoor fully-sealed composite insulating post type current mutual inductor

An outdoor fully-sealed composite insulating post type current mutual inductor comprises a mutual inductor body, an encapsulating shell and a silicon rubber sleeve. The silicon rubber sleeve is arranged on the outer surface of the encapsulating shell in a composite mode, and the surface of the silicon rubber sleeve is provided with a large skirt and a small skirt; the mutual inductor body comprises a low-voltage coil and a high-voltage coil; the low-voltage coil comprises a metering coil body, a measuring coil body and two protective coil bodies; the metering coil body and the measuring coil body are located on the upper portion of the high-voltage coil, and the two protective coil bodies are located on the lower portion of the high-voltage coil; the low-voltage coil is provided with middle taps. The current mutual inductor has the advantages that high electric insulation and sealing performance are achieved; the mutual inductor has three or four current ratios due to the design of the middle taps of the low-
