The transformer needs to install its oil conservator after arriving at the destination if its oil conservator is dismantled for transportation, to make sure there is enough oil pressure and oil mass to satisfy the needs of changed temperature during storage. 變壓器的總裝配 General assembly of the transformer ，即可做投入運(yùn)行前的試驗(yàn)項(xiàng)目。 The transformer that isn’t dismantled can be put into test item before formal running. The transformer that is dismantled should assemble the oil conservator and safety air passage first. ，訊號(hào)溫度計(jì)的同時(shí)要將溫度計(jì)座內(nèi)注滿變壓器油。 Hotline work is strictly forbidden in operating the tap changer. 無(wú)載分接開關(guān)的結(jié)構(gòu) Structure of noload tap changer 1. 此種分接開關(guān)，采用一個(gè) M422 的圓螺母，將開關(guān)吊裝于變壓器油箱蓋下，為使分接開關(guān)暴露于空氣中之部分全部密封，采用一個(gè)手柄罩，操作分接開關(guān)時(shí)，必須旋下該手柄罩。 screw off the handle cover when operating the tap changer. 13 2. SWX1310/60120 無(wú)載分接開關(guān)（如圖 2 所示）， 9 個(gè)定觸頭按 40176。 Nine fixed contactors of SWX1310/60120 noload tap changer(as shown in Diagram 2)are fiexed on the insulation base with 40176。 （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(shí)，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。 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(hù)和檢修 Maintenance and Overhauling of the tap changer 1. 無(wú)載分接開關(guān)經(jīng)常在一個(gè)位置上工作時(shí)，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(dòng)分接開關(guān) 10 周以上。 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(shí)，應(yīng)查明滲漏部位。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(guò)緊，以免過(guò)大增加旋轉(zhuǎn)力距。 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(shí)，應(yīng)注意下列問(wèn)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 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 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
