                型號及含義

                Types and Meanings


                產品結構

                Product Structure

                預裝式變電站的基本結構是將高壓電器設備、電力變壓器、低壓電器設備三個主要部分各自為一室組成“目“字型或“品“字型布置?!澳俊弊中团c“品”字型相比:“目”字型接線較為方便,故大多數采用”目”字型布置,”品”字型布置結構較為緊湊,特別是安裝場所占地面積受限制時,選用”品”字型結構較為有利。


                預裝式變電站箱體為全密封結構,箱體材料可采用優質鋼板和鋁合金板、復合彩鋼板、不銹鋼板、玻璃纖維增強水泥板等組成,現為了與周圍環境相協調,大多數箱體選用鋁合金板和玻璃纖維增強水泥板。


                預裝式變電站高壓開關設備可根據用戶需要選用產氣式、壓氣式、真空式負荷開關,SF6負荷開關,真空斷路器。高壓開關設備具有“五防”功能,可滿足終端、環網、雙電源供電方式。預裝式變電站電力變壓器可選用非金合金變壓器、油浸式全密封變壓器、干式變壓器??膳溲b瓦斯保護和溫控保護。


                預裝式變電站低壓開關可選用ABB、施耐德及國產優質開關,電容補償方式可實現共補、分補、全分補,過零投切等功能。


                預裝式變電站高低壓進出線一般為電纜,特殊需要高壓也可選用架空進線。在變電站內設有方便安裝電纜的下人孔。各獨立安裝室設有隨門開閉而自動關閉的照明燈。


                The basic structure of prefabricated substation is to make such the three major parts as high-voltage electrical equipment, power transformers and low voltage electrical equipment respectively form a separate room to constitute the layout of “Mu”(目) or “Pin” (品) word. Compare “Mu”(目) with “Pin” (品), the connection of  “Mu”(目) type is relatively convenient, therefore, the most adopts “Mu”(目) layout; while the layout structure of “Pin” (品) is more compact, especially when the occupied area of installation sites is restricted, the selection of “Pin” (品) type structure is more favorable.


                The prefabricated substation box is of fully sealed structure, whose material can use high-quality steel, aluminum alloy plate, composite color steel plate, stainless steel plate or glass fiber reinforced cement board etc. Now, in order to coordinate with the surrounding environment, most boxes selects aluminum alloy plate and glass fiber reinforced cement board.


                The high-voltage switchgear of the prefabricated substation can select as aerogenesis type, air pressing type, vacuum-type load switch, SF6 load switch or vacuum circuit breaker according to user needs. The high-voltage switchgear has "Five Prevention" functions, which can meet the terminal, ring network and dual power supply mode. The power transformer of the prefabricated substation can select non-gold alloy transformer, oil-immersed and fully sealed transformer or dry-type transformer, and gas protection and temperature control protection can be equipped.


                For the low-voltage switch of prefabricated substation, ABB, Schneider and domestic high-quality switches can be selected. With respect to capacitance compensation method, concentrated compensation, respective compensation, completely respective compensation, zero-cross-switching and other functions can be achieved.


                The high and low voltage incoming line and outgoing line of the prefabricated substation generally are cables, overhead incoming line can also be selected in case of special needs of high voltage. There is upper manhole set convenient for installation of cables inside the substation. Each separate installation room has illuminative lights which can automatically close as the door closes.

                運行與維護

                Operation and Maintenance

                高壓開關使用操作與維護,應按高壓開關的安裝使用說明書進行。低壓電器設備中,空氣斷路器,經過多次合、分操作后,會使主觸頭局部產生燒傷和碳類物質,使觸頭接觸電阻增大,應定期對空氣斷路器按使用說明書進行維護。避雷器應在每年雷雨季節前進行一次預防性試驗。


                電能計量單元按供電部門要求定期校驗。


                經常觀察變壓器的運行情況,冷卻系統是否正常,溫度自動監控是否正常,變壓器上層油溫或線圈溫度(指干式變壓器)是否正常。設備的操作,維護應由合格的電氣專業人員進行。


                The operation and maintenance of the high-voltage switch should be carried out according to the installation instruction manual. Among the low voltage electrical equipment, the air circuit breaker after many times of switching on and switching off will cause burns and carbon substances to part of main contact, therefore, the contact resistance of the contact will increase, and maintenance should be given regularly to the air circuit breaker according to the instruction manual. A preventive test should be conducted to the arrester prior to the annual thunder rain season.


                The electric energy metering unit should be calibrated regularly according to the requirements of the power supply department.


                Observe the operation of transformer frequently to see whether the cooling system, automatic temperature monitoring, and oil temperature of the upper layer of the transformer or coil| temperature (referring to dry-type transformers) are under normal condition. The operation and maintenance of the equipment should be carried out by qualified electrical professionals.


                安裝

                Installation

                箱變的基礎參考圖由生產廠家根據方案提供。用戶也可根據需要自行設計,但須與生產廠家溝通協商。 在箱變基礎的一側及四周埋好接地極,變壓器接地與防雷接地可以共用一個接地系統,引至箱變基礎平臺的接地線應不少于兩根,并確保接地電阻R≤4。

                箱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。


                The basic reference drawing of the box-type substation is provided by the manufacturer according to the program. The user can also make self-design according to the needs, but should communicate and consult with the manufacturer.


                Bury the lightning conductors one side of and around the box-type substation foundation. A common grounding system can be shared for the grounding of the transformer and lightning protection. The grounding lines led to the foundation platform of the box-type substation should be not less than two and the grounding resistance should be guaranteed to be less than or equal to 4Ω (R≤4Ω).


                The gap between the base and the foundation of the box-type substation should be sealed with cement mortar to prevent rain water from entering the cable room.
