DG

电控设备用单相变压器

Electronic Control Equipment With

Single Phase Transformers

▁ 产品概述 /Product overview

DG 系列单相电控设备用变压器，产品符合国外 DIN VDE0550《小型变压器规范》，国际电工委员会标准 IEC742《安全变压器》及国家
机械工业部 JB/T8750《电控设备用变压器》等国际、国家标准。

DG 系列单相变压器广泛适用于交流 50 、 60HZ ，额定电压 800 V 及以下，额定容量 315 kVA 及以下的低压成套开关设备及电气传动
控制设备用干式变压器。
对于用于变流主电路中的电控变压器，某些情况下，外部短路及元件故障可能产生异常应力，需进行特殊设计。
DG series of single-phase electrical control equipment transformers are in line with international and national standards such as DIN VDE0550
code for small transformers, IEC742 safety transformers of international electrotechnical commission and JB/T8750 of national ministry of
mechanical industry.
DG series single-phase transformers are widely used for ac 50, 60HZ, rated voltage 800 V and below, rated capacity 315 kVA and below low-
voltage switchgear sets and dry type transformers for electric drive control equipment.
For the electric control transformer used in the main circuit of converter, in some cases, the external short circuit and component fault may
produce abnormal stress, which requires special design.
