變壓器分接開關(guān)控制機(jī)構(gòu)設(shè)計(jì)計(jì)算（方案2-轉(zhuǎn)換觸頭）（本科畢業(yè)論文設(shè)計(jì)）
摘 要


從嚴(yán)格意義上講，分接開關(guān)應(yīng)稱為變壓器繞組的抽頭變換裝置，即在變壓器繞組的不同部位設(shè)置分接觸頭，調(diào)換分接抽頭的位置，改變其變壓器繞組的匝數(shù)，從而達(dá)到因負(fù)荷變化引起電壓波動(dòng)的調(diào)壓作用，穩(wěn)定電網(wǎng)電壓。
該課題研究的主要內(nèi)容是利用單向離合器，使兩對(duì)齒輪齒條傳動(dòng)不發(fā)生干涉。更重要的內(nèi)容是變壓器分接開關(guān)的控制機(jī)構(gòu)的設(shè)計(jì)。我們把這些控制機(jī)構(gòu)都設(shè)計(jì)成不同的凸輪轉(zhuǎn)動(dòng)形式的機(jī)構(gòu)。故凸輪的形狀決定了控制機(jī)構(gòu)。我們把凸輪輪廓的表面做成凹槽，從動(dòng)件的滾子置于凹槽中，依靠凹槽兩側(cè)的輪廓曲線使從動(dòng)件于凸輪始終保持接觸。從而我們主要是研究凸輪的運(yùn)動(dòng)特性，利用不同的凸輪曲線獲得相應(yīng)的運(yùn)動(dòng)。

Abstract

Says from the strict significance, tap switch is said to be the transformer winding's tap transducer. Namely that meeting the tap in transformer winding's different spot establishment, exchanging the tap switch’s position, and changing the transformer winding's number of windings. So it can achieve the load change to cause the voltage hunting accent to press the function and stable network voltage.
This topic research primary coverage is that use the free-wheeling system to make two counter gear rack drive do not have the interference. The more important content is the design of the transformer tap switch's control mechanism. We design these control mechanism the different cam rotation form the organization. So the cam shape has decided the control mechanism. We make cam contour's surface the scoop channel, puts in the scoop channel from the moving parts roller. The dependence scoop channel both sides' profile curve causes from the moving parts maintains the contact throughout in the cam. Thus we are mainly study the cam the state of motion, using the different cam curve to obtain the corresponding movement.
