【摘要】：大型變壓器生產(chǎn)完成以后,受運(yùn)輸條件及投運(yùn)時(shí)間的影響,并不會(huì)及時(shí)運(yùn)送到變電站現(xiàn)場(chǎng),運(yùn)輸之前都要充氣儲(chǔ)存一段時(shí)間,儲(chǔ)存期間,變壓器內(nèi)部的氣體壓力、露點(diǎn)、環(huán)境溫濕度都會(huì)對(duì)變壓器的絕緣造成影響,進(jìn)而影響變壓器的安全狀況,保證變壓器的儲(chǔ)存安全是大型變壓器正常運(yùn)輸?shù)浆F(xiàn)場(chǎng)并安全投運(yùn)的前提條件。針對(duì)大型變壓器的儲(chǔ)存安全,研制了一套大型變壓器儲(chǔ)存狀態(tài)在線監(jiān)測(cè)系統(tǒng),可實(shí)時(shí)監(jiān)測(cè)儲(chǔ)存在靜放場(chǎng)地的變壓器的內(nèi)部氣體壓力、露點(diǎn)、環(huán)境溫濕度等影響變壓器安全狀況的參數(shù),實(shí)現(xiàn)了實(shí)時(shí)預(yù)警功能,改變了目前封閉式監(jiān)測(cè)的現(xiàn)狀。本課題主要研究了以下內(nèi)容:分析了變壓器儲(chǔ)存過(guò)程中狀態(tài)監(jiān)測(cè)的必要性,設(shè)計(jì)了大型變壓器儲(chǔ)存狀態(tài)在線監(jiān)測(cè)系統(tǒng)。闡述了大型變壓器儲(chǔ)存狀態(tài)在線監(jiān)測(cè)系統(tǒng)的整體結(jié)構(gòu),包括其組成和功能。設(shè)計(jì)并完成了系統(tǒng)的硬件電路,詳細(xì)介紹了變壓器儲(chǔ)存運(yùn)輸狀態(tài)監(jiān)測(cè)系統(tǒng)數(shù)據(jù)控制中心、自動(dòng)補(bǔ)氣裝置及氣體自動(dòng)干燥狀態(tài)的設(shè)計(jì)開(kāi)發(fā)過(guò)程。完成本軟件平臺(tái)用到的數(shù)據(jù)庫(kù)的設(shè)計(jì)開(kāi)發(fā),網(wǎng)站系統(tǒng)整體設(shè)計(jì)和開(kāi)發(fā)部署。
[Abstract]:After the completion of large-scale transformer production, due to the influence of transportation conditions and operation time, it will not be transported to the substation site in time. Before transportation, it must be inflated and stored for a period of time. During the storage period, the gas pressure and dew point inside the transformer, The environmental temperature and humidity will affect the insulation of the transformer, and then affect the safety of the transformer. To ensure the storage safety of the transformer is the prerequisite for the normal transportation and safe operation of the large transformer. In view of the storage safety of large transformers, an on-line monitoring system for storage status of large transformers is developed, which can real-time monitor the internal gas pressure and dew point of transformers stored in static discharge sites. The parameters of environmental temperature and humidity which affect the safety condition of transformer realize the function of real-time warning and change the current situation of closed monitoring. The main contents of this paper are as follows: the necessity of condition monitoring during transformer storage is analyzed and the on-line monitoring system of large transformer storage condition is designed. The whole structure, composition and function of online monitoring system for large transformer storage state are described. The hardware circuit of the system is designed and completed, and the design and development process of the data control center, the automatic gas supply device and the automatic drying state of the transformer storage and transportation state monitoring system are introduced in detail. Complete the design and development of the database used in this software platform, the overall design and development of the website system.
