  • SG(B)10型干式电力变压器

    SG(B)10型H级干式变压器是我厂与沈阳变压器硏究所合作研制开发的新一代高科技产品,具有可靠、安全、环保、节能等优点。该产品特别适用于防火要求高、负荷波动大、高湿度、通风条件差等恶劣的环境中,如:机场、高层建筑、海轮及海上钻井平台、石油化工厂、矿山井下、核电站等。

    Introduction
    As a new generation of high-tech products, SG (B) 10 H-class Dry-type Power Transformer is developed under the cooperation of our company and Shenyang Transformer Research Institute, possessing reliable, safe, environmentally friendly and energy-saving features. This product is particularly suitable in places with adverse conditions such as airports, tall buildings, ships and offshore drilling platforms, petrochemical plants, mines, and nuclear power station, where the fire proofing requirements, load volatility and humidity are high and the ventilation is bad.
  • 产品特点
    可靠性强、耐温等级高:
    高压绕组采用饼式结构,低压绕组采用箔式或饼式线圈,线圈与空气有直接的、大面积的接触,散热状况很好。产品按H级绝缘设计,运行温度为180度,而主要绝缘材料NOMEX纸是可以耐220度高温,这种选择使得绝缘材料有很大的耐热裕度(有40度的裕度),可以保证变压器能在120%长期过负荷、IP45条件下无强迫风冷长期满负荷运行。

    电气性能好,局部放电小:
    NOMEX纸有较高的电气强度,哪怕在250度的高温下仍然有很高的表面和体积电阻,不仅如此,更重要的是它有较小的介电常数。这在以空气为介质的干式变压器中,是极其重要的。

    机械强度高:
    变压器采用VPI系统真空压力浸漆处理工艺,高低压绕组均用高粘接性能的H级绝缘漆高温聚合固化,使绕组成为一个坚固整体,它有效的保护了线圈不受外部各种潮湿、污秽物质的侵害,并有一定的韧性。使变压器能够承受大电流突发短路故障。加上这种结构不存在由于导体与绝缘材料的热膨胀系数不一样而在局部严重过热时造成变压器损害。因此变压器有良好的机械特性和抗热击能力(可以在-50度以下立即加满负荷)。

    安全性好:
    难燃自熄、防爆NOMEX纸不含任何毒素,限氧指数高,即使被燃烧也不会释放出有害气体,因此便于人员的疏散和消防人员的抢救。

    环保性好:
    干式变压器无论在制造、运行和使用寿命结束后都不会对环境造成危害。当产品报废后,纸可以无毒焚化处理,而铜和铁可以回收。

    Good reliability and high level of temperature durance:
     With a pie-shaped high voltage winding and foil or pie-shaped coils in low voltage winding, Massive area of the coils is able to contact the air directly, which is helpful for heat dissipation. The insulation level of the product is H when designed, and its maximum operating temperature is 180 ℃. NOMEX paper is the major insulating material, with a heat resistance of 220 ℃ and a heat resistance margin of 40 ℃. The design and materials of the product ensure that it runs at 120% overload for a long time or operate at full load under IP45 without forced wind cooling for a long time.

    Excellent electrical performance and small partial discharge: 
    With a higher electrical strength, the surface and volume resistances of NOMEX paper remain high even in an environment with 250 ℃ in temperature. What's more, the permittivity of NOMEX paper is very small. It is extremely crucial for dry-typer transformers with air as medium.

    High mechanical strength: 
    The transformer is processed with vacuum pressure dip-coating process of VPI system, and the low and high windings are aggregated and solidified with excellent adhesive H-class insulation paint. As a result, the windings form into a solid unit with certain tenacity, which effectively protects the coils from any kinds of dampness and contaminants. Thus the transformer is capable of bearing accidental short circuit due to heavy current. In addition, such structure does no harm to the transformer caused by partial overheat when thermal expansion coefficients of the conductor and the insulating material mismatches. Therefore, the transformer possesses good mechanical strength and anti-heat capability, and can be immediately fully loaded at 50 ℃ below zero.

    Safety: 
    The anti-explosion NOMEX paper is hard to burn and self-extinguishing. It is devoid of any toxins with high limiting oxygen index. Even if it burns, no noxious gas will be released, which makes it easier for personnel dispersion and rescuing work of firefighters.

    Environmentally friendliness:
    The dry-type transformer will do no harm to the environment when it is manufactured and in operation, and even when its  service life ends. NOMEX paper can be incinerated with no toxins left and copper and iron can be recycled after the product is scrapped.
