【正文】 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。 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。 Hotline work is strictly forbidden in operating the tap changer. 無載分接開關(guān)的結(jié)構(gòu) Structure of noload tap changer 1. 此種分接開關(guān)，采用一個 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，采用一個手柄罩，操作分接開關(guān)時，必須旋下該手柄罩。 Whether the transformer leaks or seeps oil. （ 2） 產(chǎn)品與零件有無損壞。此類變壓器一律裝滿油運輸，應(yīng)附帶的零件，配套件，出廠技術(shù)文件等，另裝成箱與變壓器一起發(fā)運。 Completely switch off transformer room door and those can be opened for all switch devices, all switches should stay at switchoff position. 按操作程序合閘 11KV 進(jìn)線電源，觀察高壓室指示儀表，若正常，變壓器方可投入運行。 g、 所有母線是否連接良好； If all buses is better connected。 Packaged substation should be hoisted from base and hoisted by special tool, see relative illustration. And note hoisting mark. 箱式變底座與基礎(chǔ)之間的縫隙用水泥沙漿抹封，以免雨水進(jìn)入電纜室。 Packaged substation includes shell and RM6 load switch cabi and electric transformer, which is also basic structure.. 外殼和隔板 Shell and isolation board 開關(guān)柜的外殼 采用 不銹鋼板，內(nèi)部 隔板 采用 優(yōu)質(zhì)鋼板制成，具有很強的抗氧化、耐腐蝕功能，且剛度和機械強度比普通低碳鋼板高。 在系統(tǒng)的安裝和運行期間，要遵守所有相關(guān)的 IEC 規(guī)范及國家或地方相關(guān)的安全導(dǎo)則，還應(yīng)考慮江蘇長江電器股份有限公司提供的有關(guān)資料。 ? Manual should be placed where it is easy for installation, operation and maintenance personnel to reach。 ? Must assure that applicability and safety for connection condition and operation regulation for electric equipment。 ? 確保由專職電氣人員進(jìn)行安裝、操作和維護(hù)。 ? 不要超出開關(guān)設(shè)備在正常工作條件下的技術(shù)參數(shù)里規(guī)定的負(fù)載。公司保留對提供的數(shù)據(jù)和圖解的更改權(quán)力，需更改時，不另行通知。C 日平均相對濕度 Daily mean relative humidity 95%及 以下 95% or less 月 平均相對濕度 Monthly mean relative humidity 90%及以下 90% or less 7 安裝場所的海拔高度 Altitude height for installation site 1000m 及以下 1000m or less 地震烈度 Earthquake intensity: 不超過 8 度 Not over degree 8 沒有火災(zāi)、爆炸危險，沒有嚴(yán)重污穢及化學(xué)腐蝕的場所。 User shall construct according to packaged substation foundation reference drawing provided by manufacturer (user also can himself design it under actual demand). 在箱式變基 礎(chǔ)的一側(cè)或四周埋設(shè)好接地極，變壓器接地與防雷接地可以公用一個接地系統(tǒng)。 c、 主要電器通斷是否靈活可靠； If major electric appliance switches on or off in flexible and reliable form。 l、 檢查電容器外殼的接地是否良好，放電系統(tǒng)是否可靠； If grounding for capacitor shell is better and if electric discharge system is reliable。凡本系列變壓器經(jīng)正常運輸后，不需作吊芯檢查，即可裝配有關(guān)拆卸的零部件，做驗收試驗項目，合格后，便可投入運行。 Inclination pitch of the transformer shall not exceed 15176。拆卸運輸?shù)淖儔浩鳎仨毾妊b好儲油柜，安全氣道。 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。 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(jìn)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(jìn)行干燥處理。 Note:DQS36KV SF6 ring main unit could be seen in DQS36KV SF6 All insulated inflatable ring main unit Installation, usage and maintenan
