【正文】 has many advantages, such as, less parts, higher reliability, no maintenance and so on. It provides hardware basement for enhancing stability of breakers and also can be used to realize intellectual control.Focuses is placed on the reliability of the vacuum circuit breaker control in this paper. First of all the requirements for the the actuator of vacuum circuit breaker were analysised. Typical permanent magic actuator of the structure and principle are discussesed, according to the characteristics of permanent mag actuator,which provided a theoretical foundation for control. Then based on the theory analysis on the vacuum circuit breaker, the hardware control system design, coding and decoding using EPM7064 measures are adopted to improve the permanent magic actuator operation last, considering the work characteristics and system performance requirements for permanent magic actuator, integrated hardware and software aspects, and the control system in antiinterference were improved, thus one way to seek more stable and reliable hardware and software implementation techniques can be achieved. Both hardware and software systems in terms of permanent magic actuator of the control system was introduced detailedly in this reserach. The hardware contains power supply modules, manual control unit, munication module, data processing module and subclosing coil driver module. And the sofeware contains main module, code and decode module of CPLD, data processing module and munication module,The functions of manual control, PC control are presented also. Some design experience and design methods in the research and realization of the reliability of the process control device are summarized, and the control hardware deficiencies were design of this work has some practical value in vacuum circuitbreakers’ control.Key words:circuit breaker。intellectual control。reliability目 錄引言 .......................................................................................................11 緒論 .................................................................................................1 中壓斷路器的現(xiàn)狀 ..............................................................................................................1 傳統(tǒng)中壓斷路器的操動(dòng)機(jī)構(gòu)............................................................................................2 真空斷路器對(duì)操動(dòng)機(jī)構(gòu)的要求........................................................................................2 永磁操動(dòng)機(jī)構(gòu)的發(fā)展及其優(yōu)勢(shì)........................................................................................3 國(guó)內(nèi)外對(duì)永磁操動(dòng)機(jī)構(gòu)的研究現(xiàn)狀 ..................................................................................4 本課題的研究?jī)?nèi)容與意義 ..................................................................................................5 本文的主要工作 ..................................................................................................................52 永磁操動(dòng)機(jī)構(gòu)的原理與分類(lèi) .........................................................6 永磁操動(dòng)機(jī)構(gòu)的分類(lèi) ..........................................................................................................6 雙穩(wěn)態(tài)永磁操動(dòng)機(jī)構(gòu)........................................................................................................6 單穩(wěn)態(tài)永磁操動(dòng)機(jī)構(gòu)........................................................................................................8 單穩(wěn)態(tài)與雙穩(wěn)態(tài)永磁操動(dòng)機(jī)構(gòu)的比較............................................................................93 永磁操動(dòng)機(jī)構(gòu)智能控制裝置硬件設(shè)計(jì) .........................................9 系統(tǒng)設(shè)計(jì)總體方案 ..............................................................................................................9 電源設(shè)計(jì) ............................................................................................................................10 單片機(jī)系統(tǒng)供電電源設(shè)計(jì)..............................................................................................10 電容器的充電電路..........................................................................................................11 分合閘驅(qū)動(dòng)模塊 ................................................................................................................12 驅(qū)動(dòng)電路原理..................................................................................................................12 光電隔離..........................................................................................................................14 控制電路與主電路的總體原理圖..................................................................................15 手動(dòng)控制單元 ....................................................................................................................15 通訊單元 ............................................................................................................................16 CPLD 編解碼單元 .............................................................................................................17 器件 簡(jiǎn)介與選型 ....................................................................................................18 核心部分 ...............................................................................................................21 數(shù)據(jù)接收單元 ....................................................................................................................224 控制系統(tǒng)軟件設(shè)計(jì) .......................................................................23 主程序模塊設(shè)計(jì) ................................................................................................................24 通訊程序模塊設(shè)計(jì) ............................................................................................................24 編解碼程序設(shè)計(jì) ................................................................................................................25 的描述風(fēng)格 ..........................................................................................................25 數(shù)據(jù)流描述......................................................................................................................26 用 maxplusⅡ進(jìn)行 CPLD 開(kāi)發(fā)的簡(jiǎn)單流程 .
