3ADT218437R0002 ABB 来自ABB瑞士的UNL 13300功率转换器

来自ABB瑞士的UNL 13300功率转换器可用于需要在更高功率范围内快速可控直流的所有工业应用。通过几个变流器并联，可以很容易地实现输出电流的分段增加。模块化设计可以安装在任何隔间系统中，最终也可以安装在现有的隔间系统中。该变换器采用标准脉冲末级控制，输出电压为24 ~ 48v，也可提供匹配的点火末级。
特性
模块化结构系统允许转换器安装在任何设计的隔间系统中。UNL 13300转换器由下列单元和可选扩展组成:
转换器模块
UNS 4680转换器模块是一个完全控制的三相桥式电路，两侧有六个晶闸管冷却。每个晶闸管串联有一个带缺陷指示开关的超高速熔断器。
交流过电压保护
UNS 4681过压保护限制多余的换向过压，并保护六个晶闸管免受外部产生的电压峰值的影响。该装置在输入侧有三相熔断器:熔断器包括一个缺陷指示开关。器件UNS 4681还包括一个单独供电的电阻。

The UNL 13300 power converter from ABB Switzerland can be used in all industrial applications where fast-controllable direct currents within the higher power range are required. An increase in the output current in stages can easily be achieved through parallel connection of several converters. The modular design enables installation in any cubicle system, eventually also in already existing ones. The converters are controlled by standard pulse final-stages with 24 … 48 V output voltage or can be supplied with matching firing final-stage.
Features
The modular construction system allows the converter to be installed in any design of cubicle system. A UNL 13300 converter consists of the following units and optional expansions:
Converter module
The UNS 4680 converter module is a fully-controlled 3-phase bridge circuit with six thyristors cooled at both sides. In series with each thyristor there is an ultra-fast fuse with defect indicator switch.
AC overvoltage protection
The UNS 4681 overvoltage protection limits the excess commutation overvoltages and protects the six thyristors against externally-generated voltage peaks. The unit has 3-phase fuses on the input side: the fuses include a defect indicator switch. The device UNS 4681 also includes a separately supplied resistor.
