封閉外殼內(nèi)的低壓交流電力線路保護(hù)器的試驗(yàn)程序 - Low - voltage power circuit breakers and ac power circuit protectors , preferred ratings , related requirements and application recommendations for
低壓電力斷路器和交流電力電路保護(hù)器的優(yōu)選額定值相關(guān)要求和應(yīng)用建議 - 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(shí)間上都占據(jù)總量60以上。因此,及時(shí)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(jì)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(jì)算斷路器主觸頭穩(wěn)態(tài)溫升的方法,并根據(jù)此時(shí)的負(fù)荷電流間接計(jì)算主觸頭回路的電阻;在硬件電路設(shè)計(jì)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(jì)帶來的特殊問題;在通信模塊的設(shè)計(jì)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。 - It's difficult to find circuit protector in a sentence. 用circuit protector造句挺難的
