Detailed Description

The invention will be further described with reference to the following drawings and specific embodiments:

example (b):

referring to fig. 1, the present embodiment provides a combined strain clamp device for repairing an improved power transmission line, which includes an original strain clamp 1; the drainage wire 2 penetrates through the original strain clamp 1 to be arranged, and an original jumper wire plate 3 is further installed at the side bottom of the original strain clamp 1; one end of a jumper wire 4 is arranged on the original jumper wire plate 3; the method is characterized in that: a first repair wire clamp 5 is arranged on the drainage wire 2; a repairing jumper wire plate 6 is arranged on the side wall of the first repairing wire clamp 5; the repairing jumper wire board 6 is provided with an interface matched with the jumper wire 4 in size; the first repair clip 5 includes a base plate 51 having a major arc cross section; a connecting groove 52 is arranged at the top gap part of the bottom plate 51; the cover plate 53 is mounted on the bottom plate 51 through the connection groove 52; the patch board 6 is mounted on the base plate 51. When the device in the embodiment is used for repairing, the first repairing jumper plate 6 is firstly installed on the drainage wire 2, and then the jumper wire 4 is taken out of the original jumper plate 3 and then inserted into the repairing jumper plate 6 on the first repairing clamp 5.
