【正文】 o load center, reduction for radius for power supply, improvement for voltage quality at end, particularly for restructuring for city power grid. 標準和規(guī)范 Standards and regulations SIK 箱式變電站 滿足 以下標準: SIK packaged substation meets following standards: 1. GB/T1746798 高低壓預裝式變電站 Hi/lowvoltage prefabricated substations 2. GB198589 交流高壓隔離開關和接地開關 AC hivoltage isolation switch and grounding switch 3. GB1102289 高壓開關設備通用技術條件 General technical condition for hivoltage switch device 4. DL/T 40291 交流高壓斷路器訂貨技術條件 Purchase technical condition for AC hivoltage breaker 5. DL/T 40391 6~35kV 戶內真空斷路器訂貨技術條件 Purchase technical condition for 6~35Kv indoor vacuum breaker 6. DL/T 4041997 戶內交流高壓開關訂貨技術條件 6 Purchase technical condition for indoor AC hivoltage switch 7. DL/T 48692 交流高壓隔離開關訂貨技術條件 Purchase technical condition for AC hivoltage isolation switch 8. DL/T5372020 高壓 /低壓預裝箱式變電站選用導則 Selection and application guideline for hi/lowvoltage prefabricated packaged substation 9. DL/T 5391996 高壓開關設備的共用訂貨技術條件 Purchase technical condition for hivoltage switch device 10. 電力變壓器 Electric transformer 11. ( IEC600765:2020) 電力變壓器 Electric transformer 箱變 外殼的防護等級為 IP45, 高壓室及變壓器室防護等級為 IP33。 在系統(tǒng)的安裝和運行期間,要遵守所有相關的 IEC 規(guī)范及國家或地方相關的安全導則,還應考慮江蘇長江電器股份有限公司提供的有關資料。C 日平均值不大于 +35176。C 最低溫度 Min temperature 15176。 And it is such place where there is free from fire, explosion, serious dirtiness or chemical corrosion. 耐內部故障電弧性能 Electric arc resistance for interior failure SIK 箱式變電站在設計上已考慮到箱變內部故障電弧的問題,并在高壓室及低壓室間留有壓力釋放通道,根據 GB17467 和 IEC298 進行了嚴格的試驗,能有效地保證設備及操作人員的安全。 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 開關柜的外殼 采用 不銹鋼板,內部 隔板 采用 優(yōu)質鋼板制成,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。 出現內部故障時,高壓室內氣壓升高,由于柜門已可靠密封,高壓氣體將沖開壓力釋放板釋放 至變壓器室 。 as cabi door has been reliably sealed, so highpressure gas shall impact and open up pressure relief board and relieve it into transformer room. Installation for packaged substation 用戶應按生產廠提供的箱式變基礎參考圖施工(用戶也可根據需要自行設計)。引至箱式變基礎平臺的接地引線應不少于兩根,并確保接地電阻小于等于 4 歐姆。 Packaged substation should be hoisted from base and hoisted by special tool, see relative illustration. And note hoisting mark. 箱式變底座與基礎之間的縫隙用水泥沙漿抹封,以免雨水進入電纜室。 After cable enters cable room, this must seal with clearance between cable and infed pipe for better waterproof performance. 5.箱式變電站的操作與維修 Operation and maintenance for packaged substation 箱式變在安裝維修后,在投入運行前應檢查下列項目: After packaged substation is installed and repaired。 b、 操作機構是否靈活; If manipulation device is flexible。 d、 儀表與互感器的匹配是否正確,接線及極性是否正確; If instrumentation correctly matches with mutual inductance meter and if wiring and polarity are correct e、 電器輔助接點的通斷回路是否可靠、準確; If switchon/off loop at auxiliary joint point for electric appliance is reliable and accurate。 g、 所有母線是否連接良好; If all buses is better connected。 i、 表計及繼電器動作是否準確無誤; If meter pointer and relay activation is accurate without any error。 k、 變壓器的溫控裝置是否已調到規(guī)定的使用溫度; If thermostatic controller for transformer has been adjusted to specified operation temperature。 m、 箱式變投運前應對高低壓配電設備、變壓器計量裝置等進行必要的試驗,試驗合格后,才允許投運。 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 進線電源,觀察高壓室指示儀表,若正常,變壓器方可投入運行。 if normal, this only can run transformer. 閉合低壓室總開關,觀察電壓指示儀表,若正常,再分別合分路開關,箱式變投入正常運行。 if normal, respectively switch on branch switch, then this puts packaged substation into normal operation. Power Transformer 適用范圍 Scope of application 本說明書運用于容量為 6300KVA 及以下,電壓為 35KVA 以下的油浸式電力變壓器。 The instructions are suitable for oilimmersed power transformer with the capacity of 6300KVA and below and the voltage of below 35KVA. This series of transformers needn39。此類變壓器一律裝滿油運輸,應附帶的零件,配套件,出廠技術文件等,另裝成箱與變壓器一起發(fā)運。這四個吊攀可以承受變壓器總箱蓋上的吊板環(huán)僅供起吊器身之用,起吊
