產品簡介

Brief introduction to the products

SG(H)10型干式電力變壓器為三相非包封（敞開式）真空浸漬干式電力變壓器，高／低壓繞組均采用NOMEX紙包絕緣，并經H級無熔劑絕緣耐熱漆真空壓力浸漬。高溫固化處理，采用先進的VPI真空壓力浸漬工藝生產而成，與傳統的F級環氧樹脂澆注的干式電力變壓器相比，不僅所使用的絕緣材料不同，設計思想、電磁／機械／溫升計算、結構布置和生產工藝也有較大的改變，其絕緣耐熱等級、局部放電測量、負荷過載能力和對外部環境適應等方面均有較大幅度的提高和改進。因此，它將是環氧樹脂澆注干式電力變壓器更新換代的新產品?？蓮V泛應用于對防火安全、環境保護要求高（防塵、防潮、防污穢）的負荷中心，如高層建筑、商貿中心、賓館酒店、居民小區、旅游景點、港口、機場、地鐵、箱式變電站等輸配電系統。

SG (H) 10 Dry-type Power Transformer is three-phase non-encapsulation (open type) vacuum impregnation dry-type power transformer. Both high/low voltage windings adopt the NOMEX paper-covered insulation, and are immersed by H-class non-flux insulation heat resistant paint vacuum pressure. It is given high temperature curing treatment, and is manufactured by adopting the advanced VPI vacuum pressure impregnation technique. Compared with the traditional F class epoxy resin cast dry-type power transformer, not only the used insulation materials are different, but also the design ideas, calculation of electromagnetism / mechanism / temperature rise, the structural arrangement and production processes have great difference. Its insulation heat-resistance level, local discharge measurement, over load capacity and adaptation to the external environment and other aspects are improved significantly. Therefore, it will be the upgraded product of the epoxy resin casting dry-type power transformer. It can be widely used in the load center with high level for fireproofing safety and environmental protection (dust-proof, moisture-proof, anti-dirty), such as high-rise buildings, commercial centers, hotels, residential areas, tourist spots, theaters, ports, airports, subways, box-type transformer substation and other transmission and distribution systems.

產品結構

Product Structure

綠色環保：新產品高／低壓繞組以NOMEX紙作為主絕緣材料，保持極佳的電氣性能和機械強度，選用的絕緣等級達H-C(耐熱溫度180℃-220℃)級，絕緣耐熱等級高，具有自熄、難燃、阻燃等特點，能在潮濕．鹽霧等污染較重的環境中安全運行．且在750℃以上分解時不排放有毒氣體；高壓線圈采用連續式結構，低壓線圈采用箔繞結構，絕緣漆膜薄，產品壽命期后，銅材等主要材料可方便回收，不污染環境、不浪費資源。為降低產品運行噪聲，鐵心與線圈，鐵心與夾件、支撐件之間均放置彈性硅橡膠元件。

工藝先進：高／低壓線圈經過多次進行真空加壓浸漆、烘焙、固化工藝處理，漆膜滲透到位、均勻、附著力強，成形后表面光亮、不開裂，線圈機械強度高、耐沖擊性強；且高壓線圈采用連續式、低壓線圈采用箔繞式并選用高強度陶瓷支撐，極大地提高了產品短路承受能力和運行的可靠安全性；

增強過載能力：由于高／低壓線圈其絕緣層較薄，采用多氣道結構／輻向及蜂窩式結構通風散熱效果顯著，運行溫升低，產品過載能力強，可在用電高峰期負荷120%銘牌容量狀態下安全運行。

降低制造成本：由于新產品結構與環氧樹脂澆注變壓器不同，設計靈活，無需考慮模具外協加工的影響。特別是非標產品的生產周期可縮短一周以上，交付及時，滿足顧客要求。

產品配置完善：可根據需要，提供防護外殼和溫控裝置；進行風冷、熱保智能控制、實時監控──采用三相溫度自動控制系統，帶CPU接口可通過網絡實施遠程監控。

Green Environmental Protection: the new product high/low voltage windings take the NOMEX paper as the main insulation material, to keep the excellent electrical performance and mechanical strength. The selected insulation class reaches H-C class (Heat-proof temperature of 180℃一220℃) with high insulation heat-resistance level, having the characteristics of self-extinguishing, difficult-combustion and flame retardant. It can operate safely under damp, salt fog and other serious pollution environments. In addition, it will not discharge poison gas when it is dissolved above 750℃. The high voltage coil adopts the continuous structure, the low voltage coil adopts the foil winding structure, and the insulation film is thin. After the service life of the product, copper and other main materials can be easily recycled without polluting the environment or wasting the materials. In order to reduce the operating noise of the product, the elastic silicone rubber components are placed between iron core and coil, iron core and clamping piece, strutting piece and strutting piece.

Advanced technology: High/low voltage coils are given vacuum pressure impregnation, baking and curing technology treatment for many times, the paint film penetration is in place and even with strong adhesive. After shaped, the coil has bright surface, strong mechanical strength and impact-resistance and does not crack. In addition, the high voltage coil adopts the continuous type while the low voltage adopts the foil winding type and selects high strength ceramics for supporting, which greatly improves the short-circuit capacity of the product and the reliability and safe of operation.

Enhance the load capacity: due to the thin layer of high/low voltage coil, it adopts the multi-airway structure/ radial and cellular structure so that the heat dissipation effect is excellent, the temperature rise for operation is low, and the overload capacity of the product is strong. It can operate safely under 120% load of the nameplate capacity in rush hours of the power consumption.

Reduce the manufacturing costs: because the new product structure is different with the epoxy resin casting transformer and the design is flexible, it is of no need to consider the impact of mold outsourcing processing, and especially the production cycle of non-standard product can be shortened for more than one week. The delivery is timely and the requirements of the customers can be met.

Perfect product configuration: protective shell and temperature control device can be provided according to the needs; carry out air cooling, thermal protection intelligent control and real-time monitoring - adopt three phase temperature automatic control system, and remote monitoring and control can be achieved through network with CPU interfaces.
