If it is from the tank cover or the ring flange, screw the M422 round nut tightly. If it is from the upper axle or the ring flange, screw the gland nut tightly, but do not overdo in order to prevent the increased turning force distance. 3. 在檢修變壓器時(shí)應(yīng)對分接開關(guān)進(jìn)行檢修，其停留在空氣中的時(shí)間，不得超過同絕緣級次的變壓器器身在空氣中停留時(shí)間，否則應(yīng)按變壓器使用說明書的規(guī)定進(jìn)行干燥處理。如果是箱蓋和法蘭盤處滲油，應(yīng)即扭緊 M422 圓螺母。如果不需更改變電壓時(shí)，在轉(zhuǎn)動(dòng)后仍舊固定在原來的位置上，轉(zhuǎn)動(dòng)方法按本使用說明書第 7 條進(jìn)行。 Carrete del transformador Contactor movible Diagrama 1 14 From the threephase coil as shown in the above item 1, it can be seen that the position change of tap changer will correspondingly change the number of windings of transformer coil, that is to say, it changes the voltage of the transformer. 3．無載分接開關(guān)的 操作方法，首先應(yīng)切斷電源，旋下手柄罩，將定位件向上拔平，用手旋轉(zhuǎn)手柄，使其箭頭對準(zhǔn)數(shù)字牌上所需檔位，再把定位件按進(jìn)相對應(yīng)的槽口，最后旋緊手柄罩。 space. The top end of the insulation base is fixed on the ring flange while the ring flange is fixed under the tank cover by a M422 round nut. Moving contactor is positioned at the lower end of the central insulation post. There is sealing device between the upper axle and the ring flange. The handle and the locating piece are set on the top, showing the position the switch points. When rotating the handle, moving contactor moves to the corresponding position of the fixed contactor following the movement of the upper axle of the insulation post. A snapgauge is welded under the tank cover in order to prevent the turning of the whole tap changer. 無載分解開關(guān)的工作原理和手動(dòng)操作 Working principle and manual operation of noload tap changer 1． SWX1310/60120 無載分接開關(guān)與變壓器線圈聯(lián)接圖。間隔固定于絕緣座盤上，絕緣座盤上端固定在法蘭盤上，法蘭盤又被一個(gè) M422 圓螺母固定在變壓器的箱蓋下，動(dòng)觸頭套在中心的絕緣柱下端，上半軸與法蘭盤間有密封裝置，上部裝有手柄和定位件，可以指示出開關(guān)所處之位置，當(dāng)旋轉(zhuǎn)手柄時(shí)，動(dòng)觸頭隨上半軸絕緣柱轉(zhuǎn)動(dòng)到相應(yīng)的定觸頭上，為防止整個(gè)分接開關(guān)轉(zhuǎn)動(dòng)，在箱蓋下焊裝一個(gè)卡板。 This kind of tap changer adopts a M422 round nut, which hangs the tap changer under the oil tank cover of the transformer. In order to seal all the parts of the tap changer exposed in the air, a handle cover is used。 Fill the transformer oil fully into the pedestal when installing the mercurial thermometer and the signal thermometer. 概述 Introduction 1. SWX1310/60120 無載分接開關(guān)供三相中性點(diǎn)調(diào)壓使用，電壓等級為 10 千伏，負(fù)載電流限值 60A 和 120A SWX1310/60120 noload tap changer is used for threephase voltage regulation, with the voltage being 10 kilovoltage and the limited value of load current being 60A and 120A. 2. 在操作分接開關(guān)時(shí)，必須嚴(yán)格禁止帶電操作。拆卸運(yùn)輸?shù)淖儔浩鳎仨毾妊b好儲油柜，安全氣道。對于拆卸儲油柜運(yùn)輸?shù)淖儔浩鳎谶\(yùn)到貯存地后必須端裝上儲油柜，以保證有一定的油壓與油量，以適應(yīng)貯存期間溫度變化的需要。 Whether products and parts are damaged. （ 3） 易損部件，如安全氣道膜、信號溫度計(jì)、套管氣體繼電器等有無損壞。 and then according to the list of documents, check whethcer the technical documents, products and auxiliary parts are all present, and then check: （ 1） 變壓器有無漏油、滲油現(xiàn)象。 Inclination pitch of the transformer shall not exceed 15176。 When lifting the transformer, use the four joint hinges on the container sides at the same time. These four joint hinges can bear the transformer and the ring on the top tank cover is only used for the lifter. The included angle between the rope and the vertical line shall not exceed 30176。 Transportation approach of the transformer to the installation site: mainly by highway or railway transporation. This kind of transformer should be transported in fullo
