The schematic diagram of the jumping string data rigid jumper that Fig. 2 is provided for the utility model embodiment two.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides a kind of squirrel-cage wire jumper, comprising: strain insulator-string, wire jumper jockey, wire jumper, wire jumper bracing frame, conductor spacer, pull bar, wire jumper insulator string, weighted rod.Specify their connected mode below in an embodiment, there is multiple mode in the connection of above-mentioned squirrel-cage wire jumper, is elaborated below by 2 specific embodiments:
Embodiment one
See also Fig. 1, present embodiment has been introduced a kind of situation of squirrel-cage wire jumper: the rod-pulling type rigid jumper, and it is made up of bracing frame 101, wire jumper 102, weighted rod 103, pull bar 104, wire jumper jockey 105, conductor spacer 106; As shown in the figure, because the present embodiment structure is symmetrical, therefore only describe the left-half of this structure, right half part can in like manner be released by left-half.Bracing frame 101 is installed in the middle section of wire jumper 102, bracing frame 101 is fixed on the center of wire jumper 102, bracing frame 101 is installed weighted rod 103, pull bar 104 is installed in the termination of bracing frame 101, one end of pull bar 104 is connected with bracing frame 101, the other end is connected with wire jumper jockey 105, and wire jumper 102 is according to predeterminated position installation interval rod 106.
