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設備狀態(tài)檢修狀態(tài)檢修是一種以設備狀態(tài)為基礎、以預測設備狀態(tài)發(fā)展趨勢為依據(jù)的檢修優(yōu)化方式，其優(yōu)化過程為狀態(tài)數(shù)據(jù)獲取、狀態(tài)評估、檢修方式?jīng)Q策。狀態(tài)檢修方式以設備當前的實際工況為依據(jù)，而非以傳統(tǒng)的設備使用時間為依據(jù)。*市電網(wǎng)變電部分運行現(xiàn)狀：35kV及以上變電站 23座， 其中110kV站10座， 35kV站13座。 掛網(wǎng)運行的35kV以上主變壓器共37臺， 總容量.0kVA， 其中110kV主變14臺， 容量.0kVA； 35kV主變23臺， 容量.0kVA。1 狀態(tài)檢修必要性在以前的變電設備維護中，以傳統(tǒng)的定期設備檢修為主。然而，隨著新技術、新工藝在電力設備制造業(yè)中的廣泛應用，電力設備的質量和性能已經(jīng)大大提高，有的設備在設計使用年限內(nèi)已達到免維護水平，若仍延用定期檢修管理模式顯然已不符合時代的進步。傳統(tǒng)的定期設備檢修的理念和規(guī)程已不能完全適應當前電力生產(chǎn)的發(fā)展需要，為了充分保障設備運行的可靠性，狀態(tài)檢修更加顯現(xiàn)出不可替代的作用。2 狀態(tài)檢修方案2.1 狀態(tài)檢修基本流程A、 設備信息收集B、 設備狀態(tài)評估C、 設備風險評估D、 檢修策略E、 檢修計劃F、 績效評估2.2 狀態(tài)檢修方案實施狀態(tài)檢修的基礎條件是具有健全的設備管理體制；完善的檢修質量管理體系；靈活的設備運行方式；齊全的設備管理臺帳；高素質的檢修和運行隊伍及設備管理人員；先進的測試、分析設備。我們在具備以上條件的前提下從以下幾個環(huán)節(jié)入手，開展狀態(tài)檢修：（一）設備的初始狀態(tài)即初始值初始值可以是出廠值、交接試驗值、大修后首次試驗值（案例35kV*變電站1#主變大修試驗）等。例如：1、設備出廠合格證、出廠試驗記錄；2、設備使用說明書；3、安裝交接有關資料；4、設備改進、大小修施工記錄及竣工報告；5、歷年大修及定期預防性試驗報告；6、設備事故、障礙及運行分析專題報告；7、設備缺陷記錄；8、設備移動情況記錄；9、設備改造記錄。這個環(huán)節(jié)包括設計、訂貨、施工等一系列設備投入運行前的各個過程，做為一個參照標準確定檢修的恰當時機。狀態(tài)檢修不是單純的檢修環(huán)節(jié)的工作，而是設備整個生命周期中各個環(huán)節(jié)都必須予以關注的全過程的管理。（二）設備巡檢在設備運行期間，對各類設備規(guī)定的巡檢內(nèi)容和巡檢周期進行巡檢（例如日常巡視記錄、設備測溫記錄、蓄電池測量記錄等），巡檢情況有詳細的記錄，特殊天氣及滿負荷運行、大修之后重新投運的設備酌情加強巡檢，對設備的巡檢要點重點巡視，巡視人員能熟練操作巡檢中使用設備（如設備測溫儀），清楚設備的正常值范圍（如GIS各設備SF6氣壓等），給設備管理者提供綜合分析診斷的依據(jù)，進行例行性試驗或診斷性試驗。（案例35kV*變電站1#主變吊芯大修，原因日常巡視發(fā)現(xiàn)運行聲音異常，經(jīng)高壓試驗及變壓器油跟蹤色譜分析，判斷繞組抽頭溫度過高，經(jīng)吊芯大修處理后正常運行）。（三）設備狀態(tài)的周期調整設備運行中的帶電檢測項目（如SF6氣體壓力、變壓器油面溫度、輕/重瓦斯報警等），如確認其顯示數(shù)值準確度足以反映設備正常狀態(tài)、且實時數(shù)據(jù)反映設備狀態(tài)良好，不管是否到預試時間，可以延長或免除例行各類試驗。如果設備帶電檢測或巡檢中發(fā)現(xiàn)設備異常、經(jīng)歷了嚴重的不良工況等，可能危及設備安全運行，經(jīng)設備管理者裁定是否需要停電進行診斷性試驗或列入例行試驗計劃，嚴重者大修，不適宜大修的予以更換。（案例110kV*變電站1#主變瓦斯繼電器誤報信號，原因瓦斯繼電器燒毀，及時更換后正常運行）（四）狀態(tài)量的評估和處置原則狀態(tài)量達到注意值時，預示設備有可能存在或有可能發(fā)展為某種缺陷，一般是對于正在運行的設備，應跟蹤監(jiān)測，并及時報告設備管理者對于停電設備，在確認并非重大缺陷所致之前一般不宜投入運行。狀態(tài)量超過警示值時，對于運行設備盡快安排停電進行診斷性試驗或維修，并及時報告設備管理者，隱患消除前一般不應投入運行。在相近的運行和檢測條件下，同一家設備的同一狀態(tài)量不應有顯著性差異，否則應引起注意。（案例35kV*變電站1#主變變壓器油色譜跟蹤分析）（五）例行維修和試驗計劃要對設備的運行狀態(tài)進行綜合分析與判斷，據(jù)此安排當年的設備檢修計劃，工作的針對性、目的性就很強。把一臺設備歷(次)年的試驗結果作縱向比較，與同類型設備的試驗結果作橫向比較，與規(guī)程的要求值相比較，對設備運行狀態(tài)做出準確判斷。對于充油設備，由于油是設備的主要絕緣材料，還應把設備的電氣實驗和油試驗結果結合起來進行全面考慮。計劃依據(jù)設備巡檢和狀態(tài)量的評估處置原則，按照可靠、安全縝密制定例行維修和試驗計劃，而不是簡單地按基準周期定期進行。平時做好維修和試驗的預案及設備分析工作，只要有停電機會，應充分利用停電時間安排設備的維修和試驗。 （六）設備運行狀態(tài)的統(tǒng)計分析 對設備狀態(tài)進行統(tǒng)計分析，準確掌握設備的狀態(tài)。目前在線監(jiān)測技術還不夠成熟，我們要充分利用成熟的在線和離線監(jiān)測裝置和技術，如紅外熱成像技術、變壓器油氣像色譜測試等，對設備進行測試，以便分析設備的狀態(tài)，設備運行狀態(tài)的統(tǒng)計分析是一項復雜的工作，涵蓋變電運行與檢修、試驗、繼電保護、調度和安全監(jiān)察等專業(yè)，涉及面廣。我們建立了生產(chǎn)管理系統(tǒng)，利用系統(tǒng)所具有的分析和統(tǒng)計功能，為設備的狀態(tài)檢修提供比較高效的信息，以完善的管理系統(tǒng)對設備狀態(tài)數(shù)據(jù)進行綜合分析，得到準確、科學合理的結果，正確的指導狀態(tài)檢修工作。3 總結幾年來，隨著狀態(tài)檢修管理理念的大力推行，逐步建立了狀態(tài)檢修機制。通過對變電設備在線監(jiān)測數(shù)據(jù)、交接預試信息、運行信息的分析，科學地判斷設備綜合健康狀況，對設備進行狀態(tài)評估，并根據(jù)評估結果，確定維修計劃，做到當修必修、需修才修，從而節(jié)約了維修費用，減少了停電時間。 變電設備設備狀態(tài)檢修工作的實施在我局取得了良好的效果，收到了很好的經(jīng)濟和社會效益。據(jù)統(tǒng)計，近幾年來我們共推遲了20臺次變電設備的大修，節(jié)約了維修費，并提高了變電設備的設備可用率；還根據(jù)狀態(tài)評估結果，提前對1臺主變進行大修，因維修及時，避免了重大設備損壞，最大程度上維護了企業(yè)利益。參考文獻： 1狀態(tài)檢修試驗規(guī)程中國電科院07年4月版。2國家電網(wǎng)公司設備狀態(tài)檢修規(guī)章制度和技術標準匯編。3國網(wǎng)公司狀態(tài)檢修驗收細則。4基準周期為DL/T 596-1996 電力設備預防性試驗規(guī)程所列試驗周期5國網(wǎng)公司輸變電設備狀態(tài)檢修 設備狀態(tài)檢修為了促進本公司各項經(jīng)營活動由事后管理向事前管理方式的轉變，強化生產(chǎn)經(jīng)營全過程控制，提高資金使用的計劃性，特制定本管理辦法，以增加公司資金運行的透明度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.
