          产品特点 / Features

          我公司生产的 SC(B)10 系列 20kV 级、35kV 级无励磁调压干式变压器属低损耗产品,符合国家标准 GB6450、 GB/T10228 和 IEC726 的要求,并具有以下特点:
          ● 高性能、低损耗,为 9 型系列的换代产品。
          ● 选用优质硅钢片,同时大幅降低磁通密度,减小运行中硅钢片磁致伸缩量,有效降低噪音。
          ● 优化高压线圈结构,改善了层间电压和电容的分布,大大提高了产品耐受大气过电压和操作过电压的冲击能力,同时也改善了电场分布,使产品局放量进一步降低。
          ● 可配置温控系统和风冷装置,在负荷过大时自动启动风机冷却装置,有效提高设备过负荷能力。
          The SC(B)10 series 20kV class and 35kV class non-exciting voltage regulating dry type transformers produced by our company are low-loss
          products, which meet the requirements of national standards GB6450, GB/T10228 and IEC726, and have the following characteristics:
          ● High performance, low loss, and a replacement for the 9 series.
          ● Select high-quality silicon steel sheet, and greatly reduce the magnetic flux density, reduce the amount of magnetostriction of the silicon
            steel sheet during operation, and effectively reduce noise.
          ● Optimize the structure of the high-voltage coil, improve the distribution of voltage and capacitance between the layers, greatly improve the
            product's ability to withstand the atmospheric overvoltage and operating overvoltage, and also improve the electric field distribution, so that
            the product volume is further reduced.
          ● The temperature control system and air-cooling device can be configured to automatically start the fan cooling device when the load is too
            large, which can effectively improve the overload capacity of the equipment.
