摘要
Abstract
Investigation is performed on the method of arc temperature measurement in SF6 circuit breaker' s nozzle during heavy current interruptions.Tests are conducted with a 126 kV SF6 circuit breaker;the measurement is implemented by means of spectral method to obtain the spectral line intensity of Cu Ⅰ 510.5 nm,Cu Ⅰ 515.3 nm and Cu Ⅰ 521.8 nm.By using relative intensities lines method obtain the arc temperature.In order to measure the spatial distribution of arc temperature effectively,the nozzle is replaced with a transparent organic glass material from a PTFE material,which leads temperature axial distribution of the arc is effectively obtained.Measurement is performed at each interval 1 ms during the whole operating process,which obtains the variation low of arc temperature with time.The temperature measurement method established is effective for measuring the temperature variation in the whole operating process.关键词
