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?!澳俊弊中陀搿捌貳弊中拖啾?;“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,大多數箱體選用玻璃纖維增強水泥板的非金屬殼體。

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??膳渥巴咚貢;ず臀驢乇;?/p>

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 prefabricated substation is the basic structure of high-voltage electrical equipment, power transformers and low voltage electrical equipment in a chamber with a shaped layout of A of B of C "A" type compared with the "B" or "C" type; "A"-type connection is more convenient. So most of the "A"-type arrangements are adopted, but the "B" or "C"-shaped arrangement of the structure is more compact, especially in a restricted area of the installation place, the selection of "B" or "C"-type structure is more favorable.

The box of the prefabricated substation is of a sealed structure. The whole structure of the material can be high-quality steel, aluminum alloy plate, composite color steel plate, stainless steel plate or glass fiber reinforced cement board etc. For the coordination with the environment, most of the boxes have adopted the glass fiber reinforced concrete boards of non-metallic shell.

The high-voltage switching equipment of the prefabricated substation can be selected according to user's needs as air type, air pressure type, vacuum-type load switch, SF6 load switch or vacuum circuit breaker. The high-voltage switchgear with the "Five Anti" function can meet with the needs of the terminal, ring network or the mode of dual power supply. The power transformer of the prefabricated substation  can be chosen non-gold alloy transformer, full-sealed oil-immersed transformer or dry-type transforme r,which can be fitted with gas protection and temperature control protection.

For the low-voltage switch of the prefabricated substation, the ABB, Schneider and domestic high-quality switches can be selected. The compensation types of the capacitors can be realized a total compensation, sub-compensation, all sub-compensation or zero-crossing switching functions.

The high and low voltage input and output lines of the prefabricated substation are generally cables. For the special needs of the high voltage, the overhead input line can be selected. In the substation, the human-hole for the convenience of  installing cables are equipped. In the independent installation chamber, the lights are installed, which can be turned on and off automatically with the door.

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 use, operation and maintenance of the high-voltage switch should be carried out according to the Instruction Manual. After many times of operations, the main contat of the air circuit breaker in the low-voltage electrical equipment would be partially burnt or carbonized to increase the contact resistance. So the air circuit breaker should be maintained regularly according to the Instruction Manual. A preventive test of the arrester should be conducted prior to the annual storm season.

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

Check regularly the operation of transformer for its cooling systems, automatic temperature monitoring, the top oil temperature or coil temperature (for dry-type transformers). 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公用一個接地系統,引至箱式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。

The reference foundation drawing of the box-type substation is provided by the manufacturer according to the project. The user can make design by itself according to the requirements, but subject to communication with the manufacturer. 

Bury the lightning conductors at one side and around the foundation of the box-type substation. The earthing and lightning protection grounding of the transformer can be a common grounding system. The grounding lines led to the foundation platform of the box-type substation should be no less than two lines 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.
