      戶外預裝式變電站(歐式)功能及特點 Functions and characteristics








      ◆高壓側油浸式負荷開關或SF6負荷開關, 可電動升級, 為實現配網自動化打下基礎。


      ◆Fully insulated, fully sealed, less maintenance, reliable guarantee of personal safety;

      ◆compact structure, volume is only 1/3-1/5 of the same capacity Euclidean height is low;

      ◆Sub-box structure can be adopted to avoid oil pollution in transformer tank.

      ◆High voltage side adopts full range protection with double fuses, which greatly reduces the cost.

      ◆It can be used not only in loop network, but also in terminal. The cable head can be plugged in and out in case of 200A load current.

      ◆The box body adopts honeycomb double sandwich composite board, which has the functions of heat insulation and heat dissipation.

      ◆The low voltage side is equipped with an electronic phase-gap protector. When abnormal voltage occurs in the system, the main switch can be quickly interrupted.

      ◆High-voltage side oil-immersed load switch or SF6 load switch can be upgraded electronically, laying the foundation for realizing distribution automation.

      ◆Use oil-immersed or better performance SF11 series transformer.

      Technical requirements:

      ◆Refer to the combination of different actual sizes for relevant sizes.

      ◆The surface of concrete bench should be flat, and the combined substation should be fixed on the bench by pressing plate.

      ◆The type of grounding row and cable fixing bracket can be determined according to the actual situation.

      ◆Cable fixtures and ground platforms should be embedded in advance.

      ◆The location of the cable holes in and out wires depends on the specific situation.

      ◆The front of the switch must have no clearance less than 1.5m after the installation of the combined transformer, so as to facilitate operation.

      ◆Grounding grid can be made of 12 galvanized round steel or 40 *4 galvanized flat copper. Grounding resistance should meet the requirements of power department.
