 I. General Description
GZD-W series of computer monitoring DC panel system is the up-to-date series of products elaborately developed by the company by means of advanced computer technology and modern control theories in combination with the essence of domestic and foreign products in the same trade and according to the practical conditions of electric system. It is in keeping with the latest demand of transformer station without operator in charge.
The system is used as a DC source in the large, medium and small power plants, transformer stations and as well the substations and distribution stations of industrial and mining enterprises and public institutions. It is capable of power failure protection and meeting the demand of power consumption for the operation and control of automatic devices, and emergency lighting and communication and as well switching on and off of other DC operating mechanisms under conditions of normal operation and emergency. It is able to supply reliable and stable DC source for the safe operation of electric system. It is particularly applicable to and has been widely used in the transformer substations without operator in charge.
