    產品簡介

    Brief introduction to the products

    ZGS□-40.5組合式變壓器是一種風電專用箱式變電站,是將風電機組出口的0.69KV電壓升到38.5KV并網輸出的專用設備,是我公司參照歐美風力發電的經驗,結合國內風力發電的需要和現狀量身定做的專供風力發電的新產品。該產品具有成套性強、占地面積小、投資小、安裝維護方便、造型美觀、耐候性強等特點。它的出現適應了全國大范圍建立風力發電場的趨勢,是風力發電系統的最佳配套產品。


    該產品按照風電技術進行特殊設計,具有滿足風電場“一進一出”特殊要求的特點。

    分箱式結構,高壓室、低壓室和變壓器室構成單獨單元。高壓出線單元和低壓進線單元與變壓器分開,安全可靠。

    變壓器散熱片直接暴露在空氣中,散熱能力強,可防止因箱內溫度過熱而使電氣元件發生故障。

    過載能力強、損耗小、抗短路能力強、防雷能力強。

    箱體采用新型材料制成,并經過防腐噴涂處理,能耐海水、鹽霧的腐蝕。

    體積小巧,結構簡單、布置合理,運輸、安裝方便。

    產品美觀大方,與周圍環境能很好的協調一致。


    ZGS□-40.5 combined transformer is a kind of wind power special box-type substation, and is the special equipment of synchronization output to increase the voltage of wind power unit outlet from 0.69KV to 38.5KV. It is a new product specially designed for wind power generation based on that our company refers to the experience of wind power generation in Europe and the United States and combining the domestic demands for wind power generation and current status. The product is characterized with its easy to form a complete set, small occupied area, low investment, easy installation and maintenance, beautiful appearance and strong weather ability, etc. Its appearance suits to the trend of setting up the nationwide large-scale wind power plates and the product is the best matching product of the wind power generation system.


    The product is specially designed according to the wind power technology, which meets the special requirements of “one in and one out” of the wind power site.


    The sub-box-type structure, high voltage room, low voltage room and transformer room are composed of the separate units. The high-voltage coil-out unit and low-voltage coil-in unit are separate with the transformer, safe and reliable.


    The heat sink of the transformer is directly exposed to the air with strong heat dissipation capability, which can prevent the electrical components from failing due to too high temperature inside the box.


    The product is characterized by strong overload capability, low loss, powerful anti-short-circuit capability and strong lightning protection capability.


    The box is made up of new kinds of materials and treated with anti-corrosion spraying, which can withstand the corrosion of sea water and salt mist.


    It is small in size, simple in structure, reasonable in layout and convenient for transportation and installation. The product is beautiful and elegant and in good coordination with the surrounding environment.


    產品特點

    Product Features

    1、高壓側配置負荷開關+熔斷器,可以可靠的保護變壓器,低壓側配置進口隔離開關,配以高分斷能力熔斷器;

    2、高壓負荷開關與高壓熔斷器置身于全密封的變壓器油中,利用變壓器油作為絕緣介質,高壓出線端采用全絕緣硅膠電纜接頭,真正全工況、全絕緣、全密封、免維護,保證在惡劣的環境中使用壽命達20年;

    3、采用進口高燃點油作為絕緣和冷卻介質,壽命期內無須濾油、換油,密封件采用高性能的進口膠珠,與設備同壽命;

    4、箱體外門采用獨特的迷宮式密封方式,配以高彈性長壽命密封膠條,通風孔處均配有防塵設施,能有效防止風沙、風雪等對風力變的侵蝕,防護等級為IP44;

    5、可用于環網,也可用于終端,轉換方便;

    6、低損耗、低噪音、性能優越;

    7、箱體采用防盜結構;

    8、溫升低,過負荷能力強。


    1. High voltage side is equipped with load switch and fuse cutout which can protect transformer reliably while low voltage side is equipped with inlet disconnecting switch with fuse cutout of high breaking capacity;


    2. High voltage load switch and high voltage fuse cutout are put in fully sealed transformer oil and transformer oil is used as insulating medium. High voltage coil-out end adopts the fully insulated silicagel cable connectors to be in full working condition, all insulation, full sealing and maintenance free, ensuring that it can be used in hostile environment with service life up to 20 years;


    3. Imported high burning point oil is used as insulation and cooling medium. Oil filtration and oil change are not needed within the service life. Sealing element adopts imported glue beads of high performance which has the same service life with the equipment;
