【正文】 ation 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。 （圖 1） Linkage diagram of SWX1310/60120 noload tap changer and the transformer coil (Diagram. 1) 1 條所示三相線圈圖中可以看出，當(dāng)分接開關(guān)改變位置時，相應(yīng)地改變了變壓器線圈的匝數(shù)，即改變了變壓器的 電壓。 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，再把定位件按進相對應(yīng)的槽口，最后旋緊手柄罩。 Noload tap changer operates in the following way: first cut off the power supply, screw off the handle cover, pull out the locating piece upward, screw the handle with the hand to make the arrow point at the desired gear on the numerical plate, press the locating piece into the corresponding groove, and finally screw the hanle cover tightly. 分接開關(guān)的維護和檢修 Maintenance and Overhauling of the tap changer 1. 無載分接開關(guān)經(jīng)常在一個位置上工作時，為消除觸頭部分氧化膜及油 污等物，保證接觸良好，不論變壓器是否需要改變電壓，每年至少要轉(zhuǎn)動分接開關(guān) 10 周以上。如果不需更改變電壓時，在轉(zhuǎn)動后仍舊固定在原來的位置上，轉(zhuǎn)動方法按本使用說明書第 7 條進行。 If the noload tap changer often works in the same position, in order to remove the oxide coating and grease and ensure better contact, it is necessary to turn the tap changer at least 10 rounds every year, no matter whether the transformer needs to change the voltage or not. If the voltage is unnecessary to change, fix to the original position after turning. The turning method shall be operated in accordance with Item 7 in the Instructions. 2. 發(fā)現(xiàn)有變壓器油從分接開關(guān)外滲漏出時，應(yīng)查明滲漏部位。如果是箱蓋和法蘭盤處滲油，應(yīng)即扭緊 M422 圓螺母。若是上半軸與法蘭盤處滲油，則扭緊壓緊螺母，但不得扭得過緊，以免過大增加旋轉(zhuǎn)力距。 Find out the seeping place if the transformer oil seaps from the tap changer. 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. 在檢修變壓器時應(yīng)對分接開關(guān)進行檢修，其停留在空氣中的時間，不得超過同絕緣級次的變壓器器身在空氣中停留時間，否則應(yīng)按變壓器使用說明書的規(guī)定進行干燥處理。 Overhaul the tap changer when overhauling the transformer. Its exposing time in the air shall not exceed the exposing time of the transformer with the same insulation capacity, otherwise, 15 drying process shall be performed according to the provisions in the Instructions of the transformer. 4. 在檢修分接開關(guān)時，應(yīng)注意下列問題： The following problems shall be taken into consideration when overhauling the tap changer: （ 1） .檢查分接開關(guān)接觸部分的損壞情況。 Check the damage degree of the contact parts of the tap changer. （ 2） .檢查分接開關(guān)各鎖緊裝置是否松動。 Check whether the locking devices of the tap changer are loose or not. （ 3） .檢查分接開關(guān)絕緣件的損壞情況。 Check the damage degree of the insulation parts of the tap changer. （ 4） .檢查分接開關(guān)的彈簧的工作情況。 Check the working conditions of the springs in the tap changer. 16 handle cover screw nut handle locating piece numerical plate gland nut large round nut sealing element ring flange plunger ring bolt upper axle insulation post fixed contactor insulation base moving contactor screw nut snap gauge 注： DQS36 SF6 環(huán)網(wǎng)柜 見 DQS36 SF6 全絕緣充氣環(huán)網(wǎng)柜安裝使用維護手冊。 Note:DQS36KV SF6 ring main unit could be seen in DQS36KV SF6 All insulated inflatable ring main unit Installation, usage and maintenance manual 17 中華人民共和國江蘇大全長江電器股份有限公司 JIANGSU DAQO CHANGJIANG ELECTRIC CO.,LTD,. 地址：中華人民共和國江蘇省揚中市新壩鎮(zhèn)新中南路 66 號 Address: of xinzhongnanlu ,xinba, yangzhong, jiangsu， China 電話 (Tel)： 051188410918 88410413 傳真 (Fax)： 051188411218 88410467 郵編 (Mail)： 212211 : 修改日期： 2020 年 10 月 26 日 Modification Date: Year 2020 Month 10 Day 26 版本： Edition:
