产地及质量特点
Place of origin and Characteristics
硅钢片
Silicon steel sheet
全新优质晶粒取向高导磁冷轧硅钢片
New high quality grain oriented high permeability magnetic cold rolled silicon steel sheet
       产地:武钢或新日铁。激磁电流、铁损耗、饱和参数性能优越。冷轧硅钢带由于具有较高的导磁系数和较低的损耗,因此用来制作变压器具有体积小、重量轻、效率高的优势。热轧硅钢带则逊色于冷轧硅钢带,而二次片、拼接片等对变压器使用寿命危害就更不用说了。
   Origin: WISCO or Nippon Steel. Excitation current, iron loss, and saturation parameters are superior. Cold-rolled silicon steel strips have the advantages of small size, light weight and high efficiency due to their high magnetic permeability and low loss. Hot-rolled silicon steel strips are inferior to cold-rolled silicon steel strips, and secondary sheets, splices, etc. are not harmful to the service life of transformers.
变压器绕组
Transformer winding
紫铜
Copper
       产地:洛阳铜业。含铜量99.999%,国家规定:电工用铜纯度必须在99.5%以上的紫铜。黄铜可用在小功率非电力变压器上,且属于不合格违规使用。另用黄铜做变压器线圈会增加铜损(负载损耗),降低变压器使用功率等,是十分有害的。
       Origin: Luoyang Copper. The copper content is 99.999%, and the state stipulates that the copper purity of the electrician must be 99.5% or more. Brass can be used on low-power non-power transformers and is a non-conforming violation. Another use of brass as a transformer coil will increase copper loss (load loss) and reduce the power used by the transformer. It is very harmful.
母排
Busbar
绝缘油
Insulating oil
环烷基矿物油
Cycloalkyl mineral oil
       产地:新疆克拉玛依油田。清洁而透明的液体,不得有沉淀物、机械杂质悬浮物及棉絮状物质。劣质油或二次油存在加速变压器老化,噪音大、易短路烧毁,使用寿命短。
       Origin: Xinjiang Karamay Oilfield. Clean and transparent liquids must be free of deposits, suspended solids of mechanical impurities and cotton-like materials. Inferior oil or secondary oil exists to accelerate the aging of the transformer, the noise is large, the short circuit is easy to burn, and the service life is short.
绝缘纸
Insulating paper
牛皮纸/NOMEX 绝缘纸
Kraft paper / NOMEX insulation paper
       产地:许昌绝缘材料厂或美国杜邦公司。绝缘纸是变压器的重要组成部分,变压器老化、烧坏的主要原因之一是使用低价劣质绝缘纸,易发生电弧击穿,缩短了使用寿命。
       Origin: Xuchang Insulation Material Factory or DuPont Company of the United States. Insulation paper is an important part of the transformer. One of the main reasons for the aging and burning of the transformer is the use of low-cost inferior insulating paper, which is prone to arc breakdown and shortens the service life.
环氧树脂
Epoxy resin
高环氧值(>40)6101环氧树脂
igh epoxy value (>40) 6101 epoxy resin
       产地:瑞士汽巴嘉吉。F/H级蕞高耐温155℃/180℃。耐温、耐压、硬度、收缩率、吸水率、玻化温度、粘接强度、拉伸强度等技术指标对干式变压器绝缘、浇注质量非常关键。
       Origin: Swiss Ciba Cargill. The F/H grade has a maximum temperature resistance of 155 ° C / 180 ° C. Technical indexes such as temperature resistance, pressure resistance, hardness, shrinkage, water absorption, glass transition temperature, bonding strength and tensile strength are critical to the insulation and casting quality of dry-type transformers.
