Description

Temperature sensor mounting structure of radiator for reactor

Technical Field

Background

The reactor comprises an inductor and a capacitor for power compensation, and also comprises a capacitor voltage transformer which work in a higher load area; for example, the capacitor voltage transformer mainly comprises a capacitor voltage divider C1 and a capacitor voltage divider C2 formed by high-voltage capacitors and a medium-voltage transformer T. The capacitive voltage divider consists of a porcelain bushing and a plurality of series capacitors arranged in the porcelain bushing, wherein the porcelain bushing is filled with insulating oil which keeps positive pressure of 0.1MPa, and the capacitive voltage divider can be used as a coupling capacitor to be connected with a carrier device. The medium voltage transformer consists of a transformer, a compensating reactor L, BL, a lightning arrester and a damping device Z which are arranged in a sealed insulating oil tank. The primary winding is divided into a main winding and a fine tuning winding, and a low-loss reactor is connected between the primary side and the primary winding in series. Since the nonlinear impedance and inherent capacitance of the capacitor voltage transformer sometimes cause ferromagnetic resonance in the capacitor voltage transformer, the resonance is suppressed with a damping device composed of a resistor and a reactor. Because the load of the existing capacitor voltage transformer is large, the insulating oil is used for helping heat dissipation, so that the good heat dissipation effect can be ensured, but the insulating oil is better to avoid oxygen oxidation in the air at a higher temperature, a special radiator (an aluminum or aluminum alloy metal radiator) is arranged on an oil tank, the heat dissipation is helped by the insulating oil, and the purpose of measuring accuracy and ensuring the working reliability of the capacitor voltage transformer is achieved. Improper installation of the temperature sensor and the thermal conductivity of the mounting structure can affect the measurement effect of the temperature sensor.
