【正文】 控路燈控制器可以自動實現(xiàn)白天光線較暗和晚上遇到聲響時，路燈自動點亮，從而實現(xiàn)人來燈亮，人走燈滅，既方便又實用?？蓮V泛應(yīng)用于樓梯，走廊，衛(wèi)生間及生活小區(qū)等公共場所的照明控制。 四 畫出電路原理圖 晶閘管路燈自動限壓保護(hù)電路 元器件列表 元件名稱 元件參數(shù) R1 R2 2K R3 R4 R5 15K R6 2K R7 2K R8 R9 C1 200UF 50V C2 63V RP1 RP2 1K 五 .總結(jié)與體會 當(dāng)今中國的老百姓越來越重視節(jié)約能源，這個電路就是為了節(jié)約更多的能源設(shè)計的。比如近些年來，每到夏天到來，就會有許多能源高峰期，政府也會采取一些相應(yīng)措施限制人們用電。通過本次實驗，使我明白了路燈控制器的工作原理。達(dá)到了節(jié)能的目的，減少了不必要的浪費。由于光敏電阻的電阻值變化是連續(xù)的，因此在靠近臨界點時，容易造成不穩(wěn)定，在設(shè)計中若能用運放電路來完成處理，則可將運放接成電壓比較器的方式，這樣可以完成較為精確的起控 ；若采用分立元件來處理，可以采用穩(wěn)壓管來穩(wěn)定工作點，只有當(dāng)分壓大于穩(wěn)壓管的擊穿電壓時，電路才能起控。 六 .參考文獻(xiàn) 1 電力電子變流技術(shù) 王廷才編 機(jī)械工業(yè)出版社 2 晶閘管變流技術(shù)應(yīng)用圖集 王文郁編 機(jī)械工業(yè)出版社 3 電力電子變流技術(shù) 曾芳編 西安電子科技大學(xué)出版社 4 電類專業(yè)課程設(shè)計指導(dǎo) 張華編 機(jī)械工業(yè)出版 5 電力電子技術(shù)應(yīng)用 電路 王文郁編 機(jī)械工業(yè)出版社 ag an employment tribunal clai Emloyment tribunals sort out disagreements between employers and employees. You may need to make a claim to an employment tribunal if: you don39。t appealed against the disciplinary action your employer has taken against you. However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal. Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept i. If you are worried about how the time limits apply to you If you are being represented by a solicitor at the tribunal, they may ask you to sign an agreement where you pay their fee out of your pensation if you win the case. This is known as a damagesbased agreement. In England and Wales, your solicitor can39。re clear about the terms of the agreement. It might be best to get advice from an experienced adviser, for example, at a Citizens Advice Bureau. To find your nearest CAB, including those that give advice by , click on nearest CAB.
