产品介绍 /Product introduction
本系列产品用于将 20kV、35kV 电网电源直接降低为 400V 配电电源或
10kV 输电电源为用户供电，由于具有显著优点，为越来越多的工程所采用。
其主要优点有：
1. 减少占地和多级变电工程建设，具有显著的社会效益。
2. 节省工程投资，提高经济效益。
3. 减少 10kV 输变电环节，使运行维护费用明显降低。
4.采用高压小电流代替低压大电流输电，减少线路损耗，降低线路运行成本。
5.35kV、20kV 电源直接进入用电中心，有效提高供电的可靠性。
产品特点 /Characteristics of the product
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：
1. 高性能、低损耗，为 9 型系列的换代产品。
2.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。
3. 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。
4. 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。
This series product uses in the 20kV, 35kV electrical network power source
reducing is directly the 400V power distribution power source or the 10kV
electric transmission power source is the user power supply, because has
the remarkable merit, uses for more and more many projects. lts main merit
includes:
1.The reduced occupying a land area of and multistage changes the
electricity engineering construction, has the remarkable social efficiency.
2.Saves the project investment, enhances the economic efficiency.
3.Simplifies the 10kV power transformer link, causes the movement
maintenance cost to reduce obviously.
4.Uses the high-pressured undercurrent to replace the low pressure big
electric current electric transmission, reducesthe line loss, reduces the /ine
movement cost.
5.The 35kV, 20kV power source enters directly uses electricity the center,
enhances the power supply effectively the reliability.
Our company produces SC(B)10 the series 20kV level, the 35kV level adjust
the dehydration pressing type transformer without the excitation to be the
low loss product, conforms to national standards GB6450, GB/T10228 and
the IEC726 request,and has following characteristic:
1.The high performance, the low loss, is 9 series update products.
2.Selects the high quality silicon steel plate. simultaneously is large reduces
the magnetic-flux density, reduces in the movement the silicon steel plate
magnetostriction quantity, reduces the noise effectively.
3.The optimization secondary winding structure, improved the level the
voltage and the electric capacity distribution,enhanced the product tolerance
atmospheric overvoltage and switching surge impact ability greatly,
simultaneously also improved the electric field distribution. causes the
product bureau to one s limit further to reduce.
4.It may dispose warm controls the system and the forced-air cooling
installment, in the load oversized time automatic start air blower cooling
system, sharpens the equipment load ability effectively.
