Measuring Method of the Internal Temperature of UHV DC Voltage Measuring Device

Abstract

For many years, it has been difficult to measure the internal temperatures of gas insulated equipments in high voltage apparatuses. This paper presents a method of measuring the internal temperature of UHV DC Voltage measuring device, which uses the temperature sensor of fluorescent decay time optical fiber transmission as the instrument. The method could accurately measure the internal temperature when the device is running. The paper mostly expounds the selecting temperature sensor and arrangement mode of sensor and detailed test method. The test method could determine the internal temperature of UHV DC voltage measuring device, as the same time could also provide references for measuring the internal temperatures of gas insulated equipments in high voltage apparatuses.
