例句與用法
- 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(shù)，還是在事故所造成的停電時間上都占據(jù)總量60以上。因此，及時了解斷路器的工作狀態(tài)對提高供電可靠性有決定性意義；并可以大大減少盲目定期檢修帶來的資金浪費(fèi)。本文論述了斷路器機(jī)械特性參數(shù)監(jiān)測方法；提出了二次回路保護(hù)器的概念，并將跳、合閘線圈完整性監(jiān)視和二次回路保護(hù)結(jié)合起來，給出具有完整性監(jiān)視功能的二次回路保護(hù)器實(shí)現(xiàn)方案；根據(jù)斷路器生產(chǎn)廠家提供的斷路器額定短路電流分?jǐn)啻螖?shù)，計算每次分閘對應(yīng)的觸頭電壽命損耗，預(yù)測觸頭電壽命；提出根據(jù)斷路器殼體溫度和斷路器周圍空氣溫度結(jié)合斷路器熱阻來計算斷路器主觸頭穩(wěn)態(tài)溫升的方法，并根據(jù)此時的負(fù)荷電流間接計算主觸頭回路的電阻；在硬件電路設(shè)計上，采用美國ti公司最新推出的一種功能強(qiáng)大的單片機(jī)msp430，并充分考慮該芯片的適用電壓范圍給設(shè)計帶來的特殊問題；在通信模塊的設(shè)計中，解決了不同工作電壓芯片之間的接口問題，并給出了直接聯(lián)接的接線方案。
