中文拼音 [édìngjiēwēn]
額定結溫
英文
rated junction temperature-
This article aims at the boiler ' s problems in operation : 1 ) under nominal load, the smoke temperature at the outlet of hearth reaches 1200, far more exceeds 1050 the original designed temperature. this will always result in slag inside boiler and the temperature of overheater ' s pipe superheat, so that boiler cannot take nominal load and all these influence boiler ' s nomal operation heavily, 2 ) this article also studied the reason why the assistant oil becoming necessary when coal changes. during the nomal operation, many factors ( makeup of combustor and its disposal, smirch and encrust of water wall, excessive air coefficient, temperature of primary air, coal type and density of coal dust ) can deviate the designed working conditions, then affect the boiler ' s nomal operation
本文針對該鍋爐在實際運行中存在的問題：在額定負荷下，爐膛出口超溫、低溫段過熱器前煙溫高達936 ，遠遠超過815的設計值；噴燃器四周水冷壁結焦嚴重，過熱器管壁溫度超標，無法帶上額定負荷；甚至有時因燃煤質量的變化，必須投油助燃的嚴重情況進行了分析研究。在實際生產過程中，燃燒器的結構、布置，水冷壁的粘污、結垢，過剩空氣系數、一次風溫、煤種及其濃度變化等許多因素都會偏離鍋爐的設計工況，從而影響爐內的傳熱和燃燒，造成爐膛出口超溫、水冷壁結渣等問題。Touching is used to feel a certain part of the body, like the forehead or limbs with the fingers of palms, thereby detecting the body temperature, dampness or dryness ; stroking refers to examining the patient ' s some parts of the body with the hands, e. g., a swelling, to learn the shape, size and sensation of the swelling ； pressing means pushing and pressing over some parts of the body with the hands, e. g., the chest or abdomen, to make sure if they are tenderness, or have any cakings when pressed
觸用於感覺身體得某一部位，如通過觸摸額、四肢的指掌，觀測體溫、燥濕；扣是指用手檢查病人身體的一些部位，如扣膨出的部位可以感覺膨出的形狀和大小；按指的是用手推和按壓身體的一些部位，例如，按壓胸腹可以確定它們是否緊張，有無結塊。On - line monitoring of hvcb is the precondition of predicting maintenance, is the key element of reliable run, and is the important supplement to the traditional off - line preventive maintenance in fact, the faults are made by hvcb, no matter in number or in times, is over 60 % of total faults so it has determinative importance for improving the reliability of power supply and this can greatly decrease the capital waste used by - dating overhaul in this paper, the inspecting way of hvcb mechanism characteristic is discussed the concept of sub - circuit protector is presented, the scheme that we offered has been combined with sub - circuit integrality monitoring theory, to ensure that it has the two functions as a whole according the shut - off times at rated short circuit given by hvcb manufacturer, the electricity longevity loss can be calculated in each operation, and the remained longevity can be forecast too an indirect way for calculating main touch ' s temperature by using breaker shell temperature, air circumference temperature and breaker ' s heat resistance is improved in this paper, and main touch resistance can be calculated if providing the load current msp430, a new single chip microcomputer made by ti company, is engaged to develop the hardware system of the on - line monitoring device, and special problem brought by the lower supply voltage range of this chip is considered fully
高壓斷路器所造成的事故無論是在次數，還是在事故所造成的停電時間上都占據總量60以上。因此，及時了解斷路器的工作狀態對提高供電可靠性有決定性意義；並可以大大減少盲目定期檢修帶來的資金浪費。本文論述了斷路器機械特性參數監測方法；提出了二次迴路保護器的概念，並將跳、合閘線圈完整性監視和二次迴路保護結合起來，給出具有完整性監視功能的二次迴路保護器實現方案；根據斷路器生產廠家提供的斷路器額定短路電流分斷次數，計算每次分閘對應的觸頭電壽命損耗，預測觸頭電壽命；提出根據斷路器殼體溫度和斷路器周圍空氣溫度結合斷路器熱阻來計算斷路器主觸頭穩態溫升的方法，並根據此時的負荷電流間接計算主觸頭迴路的電阻；在硬體電路設計上，採用美國ti公司最新推出的一種功能強大的單片機msp430 ，並充分考慮該晶元的適用電壓范圍給設計帶來的特殊問題；在通信模塊的設計中，解決了不同工作電壓晶元之間的介面問題，並給出了直接聯接的接線方案。Under different load, when we apply this software to any time, region and cooling way, we can get the hottest spot increment and aging rating. to manufactory, the software means sounder thermal design, which will meet the load, putted forward by user, while to user, the software equal to a master who can help them decide the capacity rating of the transformer, which will fit the load. by using the software, the potential danger and the waste, caused by unfit load choice may be avoided
研究開發了計算乾式電力變壓器負載能力的計算軟體，可對于各種絕緣結構，各種冷卻方式和任一地區、任一時間下運行的變壓器在不同運行載荷下的最熱點溫升絕緣老化率進行分析和計算，同時利用該軟體製造廠可以依據用戶提出的運行負載量給出相應的熱設計方案，用戶可根據運行負載情況利用軟體計算所需變壓器的額定容量，避免額定容量選擇不當造成隱患和浪費。Full - sealed assembling capacitor is applied to ac power sys - tem 50 60hz with rated voltage of 6kv 10kv 35kv for improving power factor and quality of power grid, reducing transmission loss and raising the efficiency of transmission transformation faciliti - es. this type of capacitor has an assembling full - sealed struc - ture, and it is comprised of capacitor unit body, container, insula - ition cooling impregnant, outlet ceramic bushing, pressurereleas -
