Here a new interfluent stable power supply was proposed, which consists of two circles of magnetic flux transformer and the automatic control system
給出一種新型交流穩壓電源,由雙磁路變壓器和自動控制系統組成。During the period of measurement, the transduction circuits transform the differential pressures, the absolute pressures and the temperatures received by the sensors into the voltage signals, and then, the voltage signals are transformed into digital signals by the a / d convertor. the mcu processes these digital signals and calculates the cumulation of the flow. finally the totalizers contact with the pc by rs - 485 bus to form a distributed measuring network
在測量過程中,系統以流量計節流所獲得的差壓信號作為主信號、絕壓和溫度信號作為補償信號進行流量積算,這三種信號分別由相應傳感器感知后,經各自的物理信號測量電路轉換為電信號,再由a / d轉換模塊轉變為數字量,交微控制器進行處理、積算。The system is different from traditional silicon controlled dephasing method, such speedy modules as whole controlled electric and electronic equipment igbt and high frequency pwm controlling methods are employed, and the voltage of exchanging power supply of motor of beam pumping units can be controlled automatically, so there is no problem of power factor being decreased brought by silicon controlled phase single controlled, power factor in power net of beam pumping units " motor is enhanced really
由於雙管齊下,電機電網側的功率因數得到了大大提高。與傳統的可控硅移相控制方式不同,本系統採用全控型電力電子器件igbt等快速模塊及高頻pwm控制方式,對抽油機電機的交流供電電壓進行自動控制,不存在可控硅相控角所帶來的功率因數變差的問題,真正提高了抽油機電網側的功率因數。Intelligent tri - phase ac active reactive power instrument adopt advanced microprocessor carry out smart control, and to the inputed tri - phase ac voltage and current signal carry out accurate measurement, through cpu automatically count out the tri - phase ac active reactive power value total power, conduct clear and visual display by high brightness led display tube, it can be simultaneously transferred to standard voltage current signal to transmit output, and have super - limit control alarm standard serial communication function etc
智能三相交流有功無功功率儀表採用先進的微處理器進行智能控制,對輸入的三相交流電壓與電流信號進行精確的測量,經過cpu自動計算出三相交流有功無功功率值總功率,由高亮度led數碼管進行清晰直觀的顯示,同時可轉換成標準電壓電流信號變送輸出,並具有超限控制報警標準串列通訊等功能。Adopt advanced microprocessor carry out smart control, and to the inputed tri - phase ac voltage and current signal carry out accurate measurement, through cpu automatically count out the tri - phase ac active reactive power value total power, conduct clear and visual display by high brightness led display tube, it can be simultaneously transferred to standard voltage current signal to transmit output, and have super - limit control alarm standard serial communication function etc

本文提出了一種基於獨立正弦波逆變器的功能之上復合其他功能而成的多功能通用逆變電源系統的實現方法,此系統不僅可以作為獨立逆變電源使用,還可以與電網電壓的相位同步,作為后備式正弦波ups使用,在逆變電源和電網的相互切換時能做到對負載無影響,同時還可以由三臺逆變器進行組合自同步實現三相對稱交流輸出,實驗證明這種方式具有較強的抗三相不平衡負載的能力。Then some conclusions we could make as follows : the inferior level of population ' s education and poor traffic condition hinder the economic development severely ; there are lots of natural resources, but the methods of exploitation are unsound ; in the industry, on one hand, the traditional take most part, such as sugar factory, tea factory and hydroelectricity station, but most of th ose products quality is inferior and the ability of market competition is weak ; on the other hand, the infant industries development is very slowly ; the protruding environment problems in lincang are pollution and soil erosion
通過分析,我們可以得知本區低水平的人口素質和落後的交通條件是制約區域經濟發展的「瓶頸」因素;區內有著豐富的自然資源,但沒有從潛在優勢轉變成市場優勢;目前本區工業已形成以「糖、茶、電」為骨幹的工業結構,但產業總體發展水平低,產品質量差,缺乏市場競爭力,同時新興產業發展緩慢,開發力度不夠;由於本區以中山地貌為主,加上不合理耕作使得農業中的水土流失問題突出,工業技術的落後帶來的污染問題也在不斷加劇。分享友人
