videoconference, Secretary of the provincial Committee of Xia Baolong stressed: this year is the five water treatment 357 timetables for three years to resolve outstanding issues, obviously worked, victory of the year. The Countys departments at all levels must firmly establish the guanghui is gold and silver green development concept, convinced that Castle is not relaxed, always maintaining strategic ability and strong determination to improve the environment, consistently playing well five water treatment of winning the war, ever-higher levels of comprehensive well-off society was built. (A) lay the sewage uphill battle. This year we will river water quality improved at the county level, up to five this basic objective grasp of pollution control that focus, with the focus on three things: a good job, clear rivers reaching the County created. Organization look back special inspection, the County garbage River, black and odorous River is Dragnet investigation, timely rectification of problems found in place firmly to prevent river pollution rebound. In accordance with the one-stop strategy, improving the inferior five water quality monitoring stations work this year to ensure the Elimination of 1 provincial control, five water quality section 3 municipalities controlled deterioration, ensure the creation this year of clear rivers standards. Second, pay special attention to pollution-cutting construction of nanotubes. Intercepting nanotubes are the basis of pollution of water source engineering, engineering, matter of success or failure of water management. Urban sewage treatment, to improve effluent from sewage treatment rate, running accuracy, compliance requirement, speed up the towns support network construction, is focusing on nanotubes home last meters question. Domestic sewage treatment in rural areas, this year is the final year of the three-year action, determination to fight and the momentum around, ending the battle on which fully to ensure the realization of all County 648 formed village coverage. Also, be sure to attach importance to focus on rural domestic wastewater treatment facility operation and management, ensure that wastewater treatment facility up and running, role play, avoid the Sun problem. Third, pay special attention to the River Lake pond desilting operation. Provinces now have focused on pollution control of water go to dig up mud, as the deepening water of this years plays. Next, to jump-start an investigation line touches work, implementation plan according to the priorities and the programme of work, in accordance with the one river one policy requires detailed cleaning, dredging plan, planning ahead of time cleaning out mud way out, according to local conditions to do sludge, promote scientific resource utilization of silt and mud. (B) the heavy regulation of heavily polluting industries. Pollution of water must grab the source, wastewater is primarily the source of backward production capacity, increase the intensity of设备状态检修状态检修是一种以设备状态为基础、以预测设备状态发展趋势为依据的检修优化方式，其优化过程为状态数据获取、状态评估、检修方式决策。状态检修方式以设备当前的实际工况为依据，而非以传统的设备使用时间为依据。*市电网变电部分运行现状：35kV及以上变电站 23座， 其中110kV站10座， 35kV站13座。 挂网运行的35kV以上主变压器共37台， 总容量.0kVA， 其中110kV主变14台， 容量.0kVA； 35kV主变23台， 容量.0kVA。1 状态检修必要性在以前的变电设备维护中，以传统的定期设备检修为主。然而，随着新技术、新工艺在电力设备制造业中的广泛应用，电力设备的质量和性能已经大大提高，有的设备在设计使用年限内已达到免维护水平，若仍延用定期检修管理模式显然已不符合时代的进步。传统的定期设备检修的理念和规程已不能完全适应当前电力生产的发展需要，为了充分保障设备运行的可靠性，状态检修更加显现出不可替代的作用。2 状态检修方案2.1 状态检修基本流程A、 设备信息收集B、 设备状态评估C、 设备风险评估D、 检修策略E、 检修计划F、 绩效评估2.2 状态检修方案实施状态检修的基础条件是具有健全的设备管理体制；完善的检修质量管理体系；灵活的设备运行方式；齐全的设备管理台帐；高素质的检修和运行队伍及设备管理人员；先进的测试、分析设备。我们在具备以上条件的前提下从以下几个环节入手，开展状态检修：（一）设备的初始状态即初始值初始值可以是出厂值、交接试验值、大修后首次试验值（案例35kV*变电站1#主变大修试验）等。例如：1、设备出厂合格证、出厂试验记录；2、设备使用说明书；3、安装交接有关资料；4、设备改进、大小修施工记录及竣工报告；5、历年大修及定期预防性试验报告；6、设备事故、障碍及运行分析专题报告；7、设备缺陷记录；8、设备移动情况记录；9、设备改造记录。这个环节包括设计、订货、施工等一系列设备投入运行前的各个过程，做为一个参照标准确定检修的恰当时机。状态检修不是单纯的检修环节的工作，而是设备整个生命周期中各个环节都必须予以关注的全过程的管理。（二）设备巡检在设备运行期间，对各类设备规定的巡检内容和巡检周期进行巡检（例如日常巡视记录、设备测温记录、蓄电池测量记录等），巡检情况有详细的记录，特殊天气及满负荷运行、大修之后重新投运的设备酌情加强巡检，对设备的巡检要点重点巡视，巡视人员能熟练操作巡检中使用设备（如设备测温仪），清楚设备的正常值范围（如GIS各设备SF6气压等），给设备管理者提供综合分析诊断的依据，进行例行性试验或诊断性试验。（案例35kV*变电站1#主变吊芯大修，原因日常巡视发现运行声音异常，经高压试验及变压器油跟踪色谱分析，判断绕组抽头温度过高，经吊芯大修处理后正常运行）。（三）设备状态的周期调整设备运行中的带电检测项目（如SF6气体压力、变压器油面温度、轻/重瓦斯报警等），如确认其显示数值准确度足以反映设备正常状态、且实时数据反映设备状态良好，不管是否到预试时间，可以延长或免除例行各类试验。如果设备带电检测或巡检中发现设备异常、经历了严重的不良工况等，可能危及设备安全运行，经设备管理者裁定是否需要停电进行诊断性试验或列入例行试验计划，严重者大修，不适宜大修的予以更换。（案例110kV*变电站1#主变瓦斯继电器误报信号，原因瓦斯继电器烧毁，及时更换后正常运行）（四）状态量的评估和处置原则状态量达到注意值时，预示设备有可能存在或有可能发展为某种缺陷，一般是对于正在运行的设备，应跟踪监测，并及时报告设备管理者对于停电设备，在确认并非重大缺陷所致之前一般不宜投入运行。状态量超过警示值时，对于运行设备尽快安排停电进行诊断性试验或维修，并及时报告设备管理者，隐患消除前一般不应投入运行。在相近的运行和检测条件下，同一家设备的同一状态量不应有显著性差异，否则应引起注意。（案例35kV*变电站1#主变变压器油色谱跟踪分析）（五）例行维修和试验计划要对设备的运行状态进行综合分析与判断，据此安排当年的设备检修计划，工作的针对性、目的性就很强。把一台设备历(次)年的试验结果作纵向比较，与同类型设备的试验结果作横向比较，与规程的要求值相比较，对设备运行状态做出准确判断。对于充油设备，由于油是设备的主要绝缘材料，还应把设备的电气实验和油试验结果结合起来进行全面考虑。计划依据设备巡检和状态量的评估处置原则，按照可靠、安全缜密制定例行维修和试验计划，而不是简单地按基准周期定期进行。平时做好维修和试验的预案及设备分析工作，只要有停电机会，应充分利用停电时间安排设备的维修和试验。 （六）设备运行状态的统计分析 对设备状态进行统计分析，准确掌握设备的状态。目前在线监测技术还不够成熟，我们要充分利用成熟的在线和离线监测装置和技术，如红外热成像技术、变压器油气像色谱测试等，对设备进行测试，以便分析设备的状态，设备运行状态的统计分析是一项复杂的工作，涵盖变电运行与检修、试验、继电保护、调度和安全监察等专业，涉及面广。我们建立了生产管理系统，利用系统所具有的分析和统计功能，为设备的状态检修提供比较高效的信息，以完善的管理系统对设备状态数据进行综合分析，得到准确、科学合理的结果，正确的指导状态检修工作。3 总结几年来，随着状态检修管理理念的大力推行，逐步建立了状态检修机制。通过对变电设备在线监测数据、交接预试信息、运行信息的分析，科学地判断设备综合健康状况，对设备进行状态评估，并根据评估结果，确定维修计划，做到当修必修、需修才修，从而节约了维修费用，减少了停电时间。 变电设备设备状态检修工作的实施在我局取得了良好的效果，收到了很好的经济和社会效益。据统计，近几年来我们共推迟了20台次变电设备的大修，节约了维修费，并提高了变电设备的设备可用率；还根据状态评估结果，提前对1台主变进行大修，因维修及时，避免了重大设备损坏，最大程度上维护了企业利益。参考文献： 1状态检修试验规程中国电科院07年4月版。2国家电网公司设备状态检修规章制度和技术标准汇编。3国网公司状态检修验收细则。4基准周期为DL/T 596-1996 电力设备预防性试验规程所列试验周期5国网公司输变电设备状态检修 设备状态检修为了促进本公司各项经营活动由事后管理向事前管理方式的转变，强化生产经营全过程控制，提高资金使用的计划性，特制定本管理办法，以增加公司资金运行的透明度treatment of heavily polluting industries. According to municipal, and municipal government deployment of seven big heavy pollution industry regulation three years action plans, requirements to December 2016 end of Qian, all included shut stopped eliminated of enterprise all shut stopped eliminated in place; June 30, 2017 Qian, all included place regulation upgrade and agglomeration restructuring of enterprise by unified standard regulation in place, late not standard of enterprise are implementation discontinued; June 30, 2018 Qian, all intends Park production of enterprise relocation Park in place, late not Park of are discontinued. In the process of renovation, will focus on four aspects: to firmly close the high energy consumption and heavy pollution, hopeless enterprise governance and production lines, eliminated a number of yearly emission intensity, low value-added products of backward production capacity. Second, we must strictly enforce the space, total project Trinity environment access system, promoting industry access and environmental conditions of access of enterprises to the Park, industrial park, in principle, no longer the class on the new project. Thirdly, promoting replacement and reconstruction of heavily polluting industries, mergers and reorganizations, guide enterprises to energy conservation, recycling and low-carbon and clean production, and improve the level of green development. Four to establish a long-term supervision mechanism, increase the intensity of special inspections, investigate and punish the rectification is not in place, normal business of running anti-pollution installations do not.
