摘　　要：采用触点寿命试验机、单色仪、光电倍增管和四通道数字存储示波器组成探测系统,测量分析电触点的时变光谱,并获得了时域光谱。本文详细介绍了该光谱测量体系的构造和性能,并应用该体系对触点电弧研究,在电压DC24V,闭合电流18A条件下,检录银、银金属氧化物触点开断电弧的电压波形、强度,对获得的触点间开断电弧强度和电弧电压结果及电弧的动力学特性进行了分析。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 1 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.
