The main transformer protection device is the device that used to protect the main Transformer microcomputer, there is a complete product line.991 main transformer integrated protection measurement and control device (second lap, with the operation), 992 main transformer differential protection and control device (second lap, without the operating), 993 main transformer differential protection and control device (second lap, without the operating), 981 main transformers high backup protection and monitoring device, 982 in the main transformer backup protection measurement and control device, 983 main transformers low backup protection measurement and control device, 984 main transformer backup protection operation device, 985 main transformer non-electricity protection device. Products are widely used in power plant, substation, industrial control and other types of large projects on the main transformer protection and control that can meet the requirements of the large capacity of 110kV and below the voltage of transformer protection, products can also be concentrated group screen, full support for distribution automation system. In recent years, the company's main transformer protection device has reached nearly 1000 units, nearly 100 sets of screen projects, in all walks of life have been highly recognized and affirmed.
