Detailed description of the invention

In order to make this utility model purpose, technical scheme and advantage clearer, below in conjunction with the accompanying drawings with embodiment to this Utility model is described in further detail.

Embodiment of the present utility model: structural representation such as Fig. 1 institute of high-voltage power line line conductor spontaneous heating deicing device Showing, including ice-melt wire and device for monitoring icing, see Fig. 2, described ice-melt wire is by wire-core 1 and to be wrapped in steel wire 4 layers of aluminum conductor 2 on core 1 are constituted, and are wound with two root table topcoating in the innermost layer of aluminum conductor 2 along the winding direction of aluminum conductor 2 The inner conductor 3 of insullac, the secondary outer layer at aluminum conductor 2 is wound with the two root table topcoating contrary with inner conductor 3 winding direction The outer layer conductor 4 of insullac, described inner conductor 3 and outer layer conductor 4 are isometrical with aluminum conductor 2 and isometric；Described icing Monitoring device includes closed case 5, is respectively arranged with steady brace 6 and active pull rod 7 at the two ends of closed case 5, lives The end of dynamic pull bar 7 is connected with the spring 9 in closed case 5, is fixed with exhausted with active pull rod 7 in the bar portion of active pull rod 7 The double end contact 10 of edge, is respectively arranged with two contacts 11, Qi Zhongyi at double end contact 10 in the end of closed case 5 Individual contact 11 is connected with the inner conductor 3 on ice-melt wire, and another contact 11 is connected with the outer layer conductor 4 on ice-melt wire, And the other end of inner conductor 3 and outer layer conductor 4 is shorted together；Described closed case 5 and the junction of active pull rod 7 It is provided with metal expander 8, for the active pull rod 7 movable sealing in moving process, is filled with in closed case 5 simultaneously SF₆Gas is used for arc extinguishing, is equiped with pneumatic head 12 on closed case 5 outer wall, and SF6 gas can be from this pneumatic head 12 to airtight Add in formula case 5.

During use, being first connected on high-voltage electric power circuit insulator by the steady brace 6 of device for monitoring icing, it is movable Pull bar 7 is connected on high-voltage conducting wires, and when high-voltage conducting wires icing, the weight of high-voltage conducting wires increases, and promotes and active pull rod 7 one end The spring 9 connected is stretched, and the double end contact 10 in active pull rod 7 driven rod portion moves, until double end contact 10 and closed cover Two contacts 11 on shell 5 contact simultaneously, due to two contacts 11 respectively with the inner conductor 3 on high-voltage conducting wires and outer layer conductor 4 connect, and now, the inner conductor 3 on high-voltage conducting wires forms closed-loop path with outer layer conductor 4 and produces eddy current, causes high pressure to be led Line generates heat and melts the icing on high-voltage conducting wires, and after the icing on high-voltage conducting wires dissolves, high-voltage conducting wires lightens, closed case Spring 9 in 5 resets, and pulls active pull rod 7, makes the double end contact 10 in active pull rod 7 bar portion separate, now with two contacts 11 Inner conductor 3 and outer layer conductor 4 can not form closed-loop path and recover to normality, and high-voltage conducting wires has also recovered normal power supply.
