產品簡介

Brief introduction to the products

SC(B)11型環氧樹脂澆注干式電力變壓器其高／低壓繞組均采用環氧樹脂絕緣澆注包封，選用環氧樹脂加玻璃纖維等絕緣材料，具有自熄特性，導熱系數和阻燃性能好。低壓繞組為雙層圓筒式或銅箔繞制、高壓繞組采用分段圓筒式結構，較大容量繞組在繞組中部設置冷卻氣道，以降低繞組溫度，擴大散熱面積。繞組經脫氣并在真空狀態下澆注／干燥成型，固化后形成堅固的圓筒形整體，絕緣性能有保證、安匝分布均勻．抗短路能力強、耐雷電沖擊水平高。不會因短路產生電弧，且抗裂、耐高溫，在高溫下樹脂不會產生有毒有害氣體，阻燃、防爆，不污染環境，可增強產品的機械／電氣強度、延長產品的使用壽命。新產品廣泛應用于城鄉電網建設與改造工程、高層建筑、商貿中心、賓館酒店、居民小區、旅游景點、劇院、港口、機場、地鐵、箱式變電站等輸配電系統。特別適合于防火防爆要求高、負荷波動大以及污穢／潮濕等比較惡劣或特殊的環境之中，可在100%濕度情況下或在正常工作電壓下長期安全可靠地運行，從而減少了停電維修帶來的損失和麻煩，新產品彌補了油浸式配電變壓器的缺陷。

For SC(B)11 Epoxy Resin Casting Dry-type Power Transformer, both its high/low voltage windings adopt the epoxy resin insulation casting encapsulation, choose the epoxy resin, glass fiber and other insulation materials, and have self-extinguishing feature, good thermal conductivity and flame-retardant performance. The low voltage winding is double layer cylinder or copper foil winding while the high voltage winding adopts the segmented cylinder structure. The winding with greater capacity has cooling airway in the middle position of the winding to reduce the winding temperature and enlarge the heat dissipation area. Winding is molded by deaeration and casting /drying under vacuum condition, and solid whole cylinder is formed after curing. The insulation performance is guaranteed, and ampere is evenly distributed with strong anti-short-circuit capacity and high lighting impact resistant level. Voltaic arc will not be caused due to short-circuit. It is cracking resistant and high temperature resistant. The resin will not generate the toxic and harmful gas at high temperature, and it is flame-retardant, anti-explosive and does not pollute the environment and can enhance the mechanical/ electrical strength of the product and extend the service lift of the products. The new product is widely used in urban and rural power grid construction and renovation project, high-rise buildings, commercial centers, hotels, residential areas, tourist spots, theaters, ports, airports, subways, box-type transformer substation and other transmission and distribution systems, especially suitable for dirty/damp and other rather hostile or special environment with high level of fire-proofing and explosion-proof and large load fluctuation. It can operate safely and reliably in the long term under 100% humidity or normal working voltage so as to reduce the damage and troubles caused by the maintenance during power off. The new product also remedies the defects of the oil immersed distribution transformer.
