【摘要】：光聲光譜技術(shù)具有選擇性好、檢測范圍寬、準(zhǔn)確度高和免維護(hù)等優(yōu)點(diǎn),基于光聲光譜氣體檢測原理和變壓器油中溶解氣體的吸收光譜特征,對油中溶解氣體進(jìn)行定性和定量分析,構(gòu)建了結(jié)合動(dòng)態(tài)頂空脫氣和光聲光譜檢測的微量氣體檢測裝置,研究檢測器內(nèi)部噪聲、環(huán)境溫度和濕度等對檢測結(jié)果的影響,結(jié)合現(xiàn)場數(shù)據(jù)和實(shí)驗(yàn)分析空氣濕度的影響并提出解決方案,對比檢測了取自現(xiàn)場變壓器的油樣,結(jié)果達(dá)到了IEC和相關(guān)國家標(biāo)準(zhǔn)的要求。
[Abstract]:Photoacoustic spectroscopy has the advantages of good selectivity, wide detection range, high accuracy and no maintenance. Based on the principle of photoacoustic spectrum gas detection and the absorption spectrum characteristics of dissolved gas in transformer oil, Qualitative and quantitative analysis of dissolved gases in oil was carried out. A micro gas detection device combined with dynamic headspace degassing and photoacoustic spectroscopy was constructed to study the effects of detector internal noise, ambient temperature and humidity on the detection results. Combined with field data and experiments, the effect of air humidity was analyzed and a solution was put forward. The oil samples taken from field transformers were compared and tested. The results reached the requirements of IEC and relevant national standards.
