Abstract
The utility model discloses a DC deicing wiring structure of an overhead ground wire. The DC deicing wiring structure of the overhead ground wire includes a DC deicing device (1), a first phase conductor (2), a second phase conductor (4) and an overhead ground wire (3). The first phase conductor (2) is connected with a head end of the overhead ground wire (3) through a first shorting stub (5). The second phase conductor (4) is connected with a tail end of the overhead ground wire (3) through a second shorting stub (5). The first phase conductor (2) and the second phase conductor (4) are connected with a positive output terminal and a negative output terminal of the deicing wiring structure. Therefore, problems of large time consumption, high difficulty, high cost and the like in a process of adopting an AC deicing device for deicing for the overhead ground wire are solved.
