Dual Toroidal High Frequency CT Sensor Unit for Partial Discharge Measurement of High Power Cables

摘要

According to the present invention, by using two toroids and connecting them using a combiner, the detection signal output can be maintained evenly for each frequency band, thereby improving the quality of the detection signal and improving the signal output in the high frequency band. A dual toroidal high-frequency Citi sensor device for partial discharge measurement of a high-power cable that can be made, The configuration of the present invention includes a front left case, a front right case installed parallel to the right side of the front left case, a rear left case installed behind the front left case, and a right side of the rear left case. The rear right case installed in parallel to the front left case, the semi-circular front left toroid installed inside the above-described front right case, and installed inside the front right case to contact the front left toroid to form a front circular core. The semi-circular front right toroid forming, the rear left toroid installed inside the rear left case described above, and installed inside the rear right case described above to contact the rear left toroid described above to form a rear circular core. The semicircular rear right toroid, the upper and lower clamps for coupling or separating the front left case and the front right case and the rear left case and the rear right case, and the front circular core and the rear circular core It comprises a combiner for combining signals, an external connection jack connected to the combiner, and an insulating member installed between the rear left and right cases and the rear circular core.
