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

這篇論文的主要任務(wù)是：通過設(shè)計(jì)變壓器分接開關(guān)的控制機(jī)構(gòu)來實(shí)現(xiàn)對(duì)變壓器主觸頭、轉(zhuǎn)換開關(guān)、真空管的自動(dòng)控制。它的實(shí)現(xiàn)方法是：設(shè)計(jì)兩組齒輪齒條傳動(dòng)來準(zhǔn)確實(shí)現(xiàn)軸每次旋轉(zhuǎn)60°，而軸的旋轉(zhuǎn)帶動(dòng)所要設(shè)計(jì)的凸輪同時(shí)旋轉(zhuǎn)60°，凸輪控制并實(shí)現(xiàn)撥動(dòng)主觸頭、轉(zhuǎn)換開關(guān)、真空管的通斷與轉(zhuǎn)換。其中兩大重要任務(wù)是對(duì)齒輪齒條和凸輪的設(shè)計(jì)，這篇文章對(duì)這兩方面進(jìn)行了詳細(xì)而系統(tǒng)的計(jì)算與說明。另外這篇文中還對(duì)各部分配件進(jìn)行了選型及設(shè)計(jì)，主要實(shí)現(xiàn)對(duì)變壓器主觸頭的控制，這篇文章最終完成了對(duì)整個(gè)變壓器分接開關(guān)的控制部分裝置的裝配圖設(shè)計(jì)。另外這篇論文注重實(shí)踐，它是利用合作單位提供的M型開關(guān)的有關(guān)的圖紙資料，進(jìn)行調(diào)研和研究，最終設(shè)計(jì)出符合合作單位的要求，準(zhǔn)確實(shí)現(xiàn)其作用。

ABSTRACT

The main task of this paper is: through the design of control device of the tap switch of the transformer to achieve the control of the main contactor, the switch and the vacuum tube. It is the method: It designed two pairs of rack and pinion gearing, the rack and pinion gearing was designed to achieve accurate rotation axis every 600, and the axis of rotation would drive the cam (the cam was designed in the paper)rotating 600 at the same time. And the cam would control the main contactor, the switch and the vacuum tube to switch-on and break. There had two important problems to settle. One is the design of the rack and pinion gearing, the other one is the design of the cam. The paper had more details and the system of calculation and description of those two. This paper also represented the electrotype and design of the fitting parts of the main device. The paper was mainly represented the design of the main contactor. In the final of the paper there had the assembly diagram of the tap switch of the transformer.

Key words：gear, gear rack ,cam
