  1. Because the monitoring of electricity equipment is still in the condition of traditional prophylactic test ( monitoring off line ), wordage list and management method of handwork operation, to strengthen the real - time monitoring of the operation state of electricity equipment ( monitoring on line ), find out the anomaly of equipment, monitor and analysis the fault, then take a corresponding measures to lower the fault loss so that we can make the transition between the regulations of periodic repairing equipment and the regulations of reasonable state repair, is the work which the department of power supply and operation make much of

    針對對現有電氣設備的監測大都還處于傳統的預防性試驗(離線監測) 、文字報表、手工操作的管理方式的現狀,加強對電力設備的運行狀態進行實時的監測(在線監測) ,及時發現設備的異常徵兆、對故障進行診斷分析,並採取相應措施,把故障損失降低到最低水平,進而將目前實行的設備定期檢修制過渡到更為合理的狀態檢修制,一直是供電和運行部門十分重視的工作。
  2. Experiments have failed in the process of debugging station fire mode of the first opening segment of guangzhou metro line 3, the main reason is the delay protect module of wind valve which cut off power supply

    摘要廣州地鐵3號線首通段車站火災模式調試過程中,出現火災模式執行失敗,主要原因在於風閥延時保護模塊動作切斷電源。
  3. A novel self - bias high - voltage device structure for the start - up circuit of an off - line switching model power supply ic is described

    摘要設計了一種新的用於離線式集成開關電源啟動電路的自偏置高壓器件結構。
  4. 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。
  5. Using this novel start - up circuit structure for the off - line switching model power supply ic can save the cell area, reduce the power consumption of the circuit, and easily control and supply the larger output voltage
