It is one of my faults, that though my tongue is sometimes prompt enough at an answer, there are times when it sadly fails me in framing an excuse ; and always the lapse occurs at some crisis, when a facile word or plausible pretext is specially wanted to get me out of painful embarrassment
我有一個缺陷，那就是盡管我口伶俐，對答如流，但需要尋找藉口的時候卻往往一籌莫展。因此某些關鍵時刻，需要隨口一句話，或者站得住腳的遁詞來擺脫痛苦的窘境時，我便常常會出差錯。 -
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。 -
Experimental results show that more than 20 % stuck - open faults in part of is85 and iscas89 circuits can produce 2. 5 times iddr variation, and then can be detected by iddt testing
實驗結果表明，電路中相當一部分故障是i _ （ ddt ）可測的。並與以前的自動測試產生演算法做了比較，此演算法穩定性好、速度快且可測性測度值好。
