• 結構特點

1、產品由高壓配電裝置、變壓器及低壓配電裝置組裝而成，分成三個功能隔室（高壓室、變壓器室和低壓室）高、低壓室功能齊全。

2、高壓側一次供電有多種供電方式，高壓室結構緊湊合理、并有全面防誤操作聯鎖功能還可裝設高壓計量元件，滿足高壓計量的要求。

3、變壓器室可選擇S9、S11等低損耗油浸式變壓器和干式變壓器；變壓器室設有自起動強迫風冷系統及照明系統，可安裝軌道能方便地從變壓器室兩側大門進出。

4、低壓室根據用戶要求可采用固定或組裝式結構組成用戶所需供電方案，有動力配電、照明配電、無功功率補償、電能計量和電量測量等多種功能，滿足用戶的不同要求，并可方便用戶的供電管理和提高供電質量。

5、箱體結構采用槽鋼及角鋼制造，有較強的機械強度，外殼采用鋁合金隔熱復合板、不銹鋼板材或非金屬材料等制造、表面光滑平整。產品美觀大方，且具有較好隔熱效果和較強的防腐性能。各室之間設有隔板獨立小室，小室均設有照明裝置，由門控制其開關。變壓器室頂部裝有排風扇，自動控制變壓器溫度，增加空氣對流以降低室溫。

Structural characteristics

1, The product is assembled by high voltage distribution device, transformer and low voltage distribution device, divided into three functional compartments (high voltage room, transformer room and low voltage room), high and low voltage room function is complete.

2, The high voltage side of the primary power supply has a variety of power supply methods, the high voltage chamber structure is compact and reasonable, and has a comprehensive anti-misoperation interlock function can also be installed with high voltage metering elements to meet the requirements of high voltage metering.

3, The transformer room can choose S9, S11 and other low loss oil immersed transformer and dry transformer; The transformer room is equipped with self-starting forced air cooling system and lighting system, and the installation track can easily enter and exit from the two sides of the transformer room.

4, Low voltage room according to user requirements can use fixed or assembled structure to form the power supply scheme required by the user, with power distribution, lighting distribution, reactive power compensation, power metering and power measurement and other functions to meet the different requirements of users, and can facilitate the user's power supply management and improve the quality of power supply.

5, The box structure is made of channel steel and Angle steel, with strong mechanical strength, the shell is made of aluminum alloy heat-insulating composite plate, stainless steel plate or non-metallic materials, and the surface is smooth and smooth. The product is beautiful and generous, and has good thermal insulation effect and strong anti-corrosion performance. There is a separate partition room between each room, and each room is equipped with a lighting device and its switch is controlled by the door. The top of the transformer room is equipped with an exhaust fan, which automatically controls the transformer temperature and increases air convection to reduce the room temperature.
