  1. In view of this situation this article has conducted research to the design of metallurgy auxiliary biography with the frequency conversion table electrical machinery first multianalysis to the frequency changer and the frequency conversion table electrical machinery movement characteristic is carried out, the voltage waveform harmonious which the frequency changer outputs is big, attacks in a big way, and the voltage climbing rate reaches as high as 6600v / mu s which is 20 times ordinary sine alternating voltage, the rolling mill auxiliary biography table set the extremely strict request to the electrical machinery ; its movement frequency is very low, rate frequency in 8 - 20hz ; the velocity modulation scope is wide, the lowest movement frequency lowers to 1hz, and the starting number of times is quite frequently, each hour reaches as high as 600 - 800 time, the impact shoulders in a big way, the overload capacity request is high

    針對這一情況本文對冶金輔傳用變頻輥道電機的設計進行了系統研究。首先對變頻器和變頻輥道電機的運行特性進行詳細分析,變頻器輸出的電壓波形諧波大,沖擊大,電壓上率高達6600v / s ,是普通正弦交流電壓的20倍;軋機輔傳輥道對電機出了十分嚴格的要求:其運行頻率很低,頻率在8 - 20hz ;調速范圍寬,最低運行頻率低到0 . 5hz ,起動次數相當頻繁,每小時高達600 - 800次,沖擊大,過載能力要求較高。
  2. 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高供電可靠性有決性意義;並可以大大減少盲目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;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供的斷路器短路電流分斷次數,計算每次分閘對應的觸頭電壽命損耗,預測觸頭電壽命;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的方法,並根據此時的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。
