Development Of An DDF Unit For Power Communication
Sanming Power Supply Bureau of Fujian Electric Power Co.Ltd, Sanming 365000, Fujian, China
DDF unit is an importantpart inpower communication field. It is the connection and connection equipment between digital multiplex equipment, digital multiplex equipment and program-controlled switching equipment or data service equipment and other professional equipment. However, the traditional DDF unit needs to be tested by 2M error code, which is inconvenient to carry and will not be used if it is not for the communication staff. Especially in the remote substation, substation operation and maintenance personnel at the scene of the failure, but can not match. This paper provides a DDF communication unit, to overcome the shortcomings of existing technology, substation operation and maintenance personnel can visually see the connectivity, distance to deal with the fault, shorten the fault time, improve work efficiency.
Key words: DDF unit; / Power communication; / detection device
