Cooler Control Cabinet for Transformer
As indicated by its name, the MRD-FZK cooler control cabinet for transformer is a newly-developed model of air cooling control cabinet for power transformers. It takes PLC as its control center, and the electrical components are offered by Schneider, ABB, Siemens and other world-class manufacturers to ensure its steady performance.
Advantage
This intelligent transformer control cabinet solves control problems that operators are often faced with when using traditional relays. More specifically, it makes use of modular components instead of conventional ones, and these components are controlled by the PLC. Moreover, a human-machine interface is equipped to help users set parameters and collect information, while the RS485 communication interface facilitates remote data transmission.
Owing to these, the transformer cooling system will be controlled in a safe and reliable manner, thus not only cutting down energy consumption but also extending the life span of radiator.
