    摘要:

    采用觸點壽命試驗機、單色儀、光電倍增管和四通道數(shù)字存儲示波器組成探測系統(tǒng),測量分析電觸點的時變光譜,并獲得了時域光譜。本文詳細介紹了該光譜測量體系的構(gòu)造和性能,并應用該體系對觸點電弧研究,在電壓DC24V,閉合電流18A條件下,檢錄銀、銀金屬氧化物觸點開斷電弧的電壓波形、強度,對獲得的觸點間開斷電弧強度和電弧電壓結(jié)果及電弧的動力學特性進行了分析。

    Abstract:

    A spectroscopic measuring system was described and developed to analyze the time-varying optical spectra of electrical contacts. A simulaton system of contact life, a monochromator, a photomultiplier tube (CR114) and a four channel digital storage oscillograph are used as optical detectors, so that the precise and quick measurements can be made for the spectrums with tim. At the same time, arc voltage waveform is measured for the breaking arc at the source voltage E of 24 V and the closed contact current I of 18 A. It is shown that this system can be applied to analyse the electric arc light and voltage for spectrums, and the dynamic characteristic of the breaking arc on Ag and Ag/MeO electric contacts.
