采用高温蒸汽处理医疗废物的过程中会产生冷凝残液,为了保证灭菌彻底还需对该残液进行二次灭菌。通过试验研究和实际运行效果观察,验证了利用高温灭菌方法对冷凝残液进行二次灭菌的可行性,并对两种残液处理工艺作了比较。试验结果表明:...采用高温蒸汽处理医疗废物的过程中会产生冷凝残液,为了保证灭菌彻底还需对该残液进行二次灭菌。通过试验研究和实际运行效果观察,验证了利用高温灭菌方法对冷凝残液进行二次灭菌的可行性,并对两种残液处理工艺作了比较。试验结果表明:①利用高温灭菌的方法可以有效地杀灭冷凝残液中的细菌微生物;②温度和灭菌时间是保证二次灭菌效果的关键,只有当温度≥120℃、时间≥15 m in时才能使灭菌率达到要求;③间歇排液流程相对于集中排液流程在实际应用上具有较大优势。展开更多
文摘针对现场气体绝缘组合电器(gas insulated substation,GIS)局部放电绝缘缺陷漏报、误报情况频发的问题,文中根据GIS实际运行温度范围对GIS内部常见固体绝缘缺陷开展不同温度下间歇性放电特性试验研究,搭建GIS电-热耦合间歇性放电模拟试验平台,采用脉冲电流法、特高频(ultra high frequency,UHF)法、超声波法和气体特征组分检测法获取不同温度下固体绝缘缺陷间歇性放电特征数据并进行分析。研究发现:UHF法和脉冲电流法在不同温度下均能有效检测到试验缺陷间歇性放电UHF信号,超声波法和气体特征组分检测法无法有效采集到有效放电数据;固体绝缘表面金属污秽缺陷和内部气隙缺陷间歇性放电电压与温度呈负相关,污秽缺陷间歇性放电电压呈较为明显的线性下降趋势,气隙缺陷间歇性放电电压呈先大幅下降后较平缓线性下降趋势;污秽缺陷间歇性放电的平均放电量和UHF信号幅值与温度的升高呈正相关;污秽缺陷放电间歇性在不同温度下随放电时间的增加会增强,而气隙缺陷放电时间间隔在26℃、40℃、50℃下能由秒级发展为毫秒级,存在演变成击穿放电的风险。文中研究成果进一步丰富了GIS间歇性放电理论体系,有助于提升现场GIS间歇性放电的有效诊断率。
