【摘要】：按照國網(wǎng)公司大檢修建設(shè)要求,大量農(nóng)網(wǎng)變電站運(yùn)維、檢修工作全部歸并到地市公司檢修分公司,同時(shí)智能變電站大量投運(yùn)、變電站無人值守和遠(yuǎn)方操作的推廣應(yīng)用,原有變電站的管控模式存在的問題和困難逐步顯現(xiàn)。運(yùn)維人員開展紅外測溫的同時(shí),還要兼顧倒閘操作、日常巡視、特殊巡視,工作勞動強(qiáng)度大。高壓開關(guān)柜的絕緣能力除了柜體結(jié)構(gòu)和材質(zhì)的因素外,高壓開關(guān)室內(nèi)運(yùn)行環(huán)境的凝露、濕度、溫度等惡劣環(huán)境因素所導(dǎo)致的開關(guān)柜絕緣事故屢有發(fā)生,對安全生產(chǎn)造成了極大隱患。開關(guān)柜屬于封閉式設(shè)備,巡檢時(shí)紅外設(shè)備無法穿透柜體,對于內(nèi)部刀閘、斷路器連接處、主母線連接、電纜接頭處,無法第一時(shí)間客觀、直接、準(zhǔn)確的檢查其溫度變化情況,不能達(dá)到提前發(fā)現(xiàn)、提前預(yù)防的運(yùn)維管理要求。隨著變電站數(shù)量逐年增多,各變電運(yùn)維班組管轄范圍隨之增大,從隊(duì)部所在地到達(dá)其他變電站的平均距離達(dá)到60.73公里,個別偏遠(yuǎn)變電站的距離可達(dá)到一百公里以上,導(dǎo)致日常運(yùn)維管理中浪費(fèi)了大量時(shí)間在路程上,降低了日常巡檢效率,從而無法及時(shí)掌握設(shè)備的運(yùn)行情況。本文在現(xiàn)有運(yùn)維體系的基礎(chǔ)上,通過高壓室除濕系統(tǒng)、開關(guān)柜溫濕度在線檢測技術(shù)、戶外電氣設(shè)備在線紅外檢測技術(shù),解決了實(shí)際生產(chǎn)運(yùn)行中勞動強(qiáng)度大、巡檢頻率不高、開柜柜內(nèi)無法檢測等各類問題,并積極開展110千伏變電站的推廣工作,從整體上提升運(yùn)維過程中對設(shè)備狀態(tài)的監(jiān)控能力,進(jìn)一步推動變電設(shè)備由定期試驗(yàn)向狀態(tài)檢修的轉(zhuǎn)變,全面提升變電綜合管理水平。
[Abstract]:According to the requirements of the large maintenance construction of the national power network company, a large number of agricultural network substations are operated and maintained, and all the maintenance work is merged to the maintenance branch of the prefectural and municipal companies. At the same time, a large number of intelligent substations are put into operation, and the substation is unattended and widely used in remote operation The problems and difficulties existing in the control mode of the original substation gradually appear. Operation and maintenance personnel carry out infrared temperature measurement at the same time, but also take into account the switch operation, daily inspection, special inspection, labor intensity. In addition to the factors of the structure and material of the high voltage switchgear, the insulation accidents of the switchgear caused by the harsh environmental factors such as condensation, humidity and temperature in the operating environment of the high voltage switch room occur time and again. To the safety of production caused great hidden danger. The switchgear belongs to the closed equipment, the infrared equipment can not penetrate the cabinet body during the inspection, for the internal knife brake, the circuit breaker connection place, the main bus connection, the cable connection place, cannot first time objective, direct, accurate check its temperature change situation, Unable to meet the operational and maintenance management requirements for early detection and prevention. As the number of substations increases year by year, the scope of jurisdiction of the substation operation and maintenance teams increases, with the average distance from the team site to other substations reaching 60.73 km, and the distance from individual remote substations to more than 100 km. As a result, the daily operation and maintenance management wasted a lot of time on the distance, reduced the efficiency of daily inspection, and thus could not grasp the operation of the equipment in time. On the basis of the existing operation and maintenance system, through the high pressure chamber dehumidification system, the switch cabinet temperature and humidity on-line detection technology, the outdoor electrical equipment on-line infrared detection technology, has solved in the actual production operation the labor intensity is big, the patrol inspection frequency is not high, Open cabinets can not detect all kinds of problems, and actively develop 110 kV substation promotion work, from the overall operation and maintenance process to improve the state of the equipment monitoring ability, further promote the transformation of substation equipment from regular testing to condition maintenance, Improve the comprehensive management level of substation.
