This paper starts with resolving reliability of steam sets , then illuminates the problem and design principle of oil test device of overspeed protection system , which is made by shanghai turbine company ltd . <中文摘要> =本文从提高机组可靠性的问题入手，探讨了上海汽轮机厂所产超速保护系统注油试验装置存在的问题及改进原理。
It is proved by the result of oil test that the combination of such three parameters as the density of fissures , porosity data and permeability data can be used to evaluate the quality of reservoirs in huang - yu - re area more exactly , among which the density of fissures is the leading reference for the evaluation 实际试油结果表明裂缝密度孔隙度渗透率3个参数结合能够较好地反映该区储层的好坏，其中裂缝密度是评价储层质量的主要依据。裂缝改善了火山岩的储集性能，断裂活动控制着储层中裂缝的发育。
This paper analyzed the situation of substation equipment reparation and management of baotou electric power bureau and presented the plan of management information system of substation equipment reparation . the paper designed the structure of management information system of substation equipment reparation . the paper designed five databases such as working ticket management , power supply cut application ticket , oil test management , electrical meter test management and high voltage test management 本文分析了包头供电局变电检修管理的现状，提出了变电检修管理的信息化解决方案，并进行了系统总体设计，在统一数据平台基础上进行了数据库设计和规范化的代码设计，建立了工作票管理、停电申请票管理、油务监督管理、仪表监督数管理和高压监督管理5个专业数据库。
The paper analyses the on - line monitoring power transformer " s chromatogram of oil in the pingliang 110kv substation and investigation the status in quo of transformer insulation monitor based on chromatogram of transformer oil . after the analysis of deflection sources in routine chromatogram of oil test , the paper brings into effect successfully the equipment on the base of characteristic infiltrative film monitoring six gases dissolved in transformer oil in the pingliang substation 2 # transformer . through analyzing a great deal practical data , it is proved that the monitoring system is stable and reliable , and has the ability to show the transformer ' s running state 论文通过对平凉110kv变电站实施主变压器油色谱在线监测及目前国内外对变压器油色谱在线监测技术的现状分析，结合影响常规油色谱测量结果及误差来源分析，在平凉变电站2 #主变压器上成功实施了以渗透气体膜原理为基础的变压器油中六种溶解气体在线监测及诊断装置，通过大量运行数据分析，系统运行稳定，能正确反映变压器的实际运行情况，并有效抓住了变压器的一次故障，可作为状态维修的依据。
