Embodiment 1

[0031] Such as Figure 1 to Figure 4 As shown, the monitoring front end of the transmission line in the present invention includes a housing 10, an elastic body 20, and a strain gauge 30. The housing 10 is provided with a through hole 11 for the line fitting to pass through. The housing 10 is a detachable Symmetrical structure, the housing 10 is provided with a signal output interface; the elastic body 20 is arranged in the housing 10, and the elastic body 20 is in contact with the line fitting; the strain gauge 30 is arranged on the elastic body 20, and the strain gauge 30 is electrically connected to the signal output interface. connect.

[0032] Such as Figure 4 As shown, the line fittings in this embodiment are U-shaped hanging rings, and there are two through holes 11 on the corresponding housing 10. The housing 10 is a detachable symmetrical structure, and the two are connected by bolts. For fastening connection, the housing 10 is provided with an interface hole 12 at...

Embodiment 2

[0046] The difference between this embodiment and Embodiment 1 is that the structure of the inner elastic body 22 is different, specifically as follows:

[0047] Such as Figure 6 The shown inner elastic body 22 includes a circular arc segment B221 and a connecting segment B222. The number of the circular arc segment B221 is two. The section B222 is in a ring structure, the upper end of the connecting section B222 is arched upwards, the lower end of the connecting section B222 is arched downwards, the strain gauge 30 is set at the arched position of the connecting section B222, and the connecting section B222 is located between the two arc sections B221 In between, the two arc segments B221 are connected by a connecting segment B222.

[0048] Such as Figure 6 As shown, the strain gauges 30 on the outer elastic body 21 are symmetrically arranged on the upper and lower ends of the outer elastic body 21 . The strain gauges 30 on the inner elastic body 22 are symmetrically arr...

Embodiment 3

[0057] The difference between this embodiment and the first embodiment is that the elastic body 20 is a whole.

[0058] Such as Figure 7 As shown, the elastic body 20 is an integral structure, and the two ends are provided with arc structures to abut against the circuit fittings. This structure is simple and easy to install.

The monitoring front-end used for transmission lines includes: a housing with a through hole for the line fittings to pass through, the housing is a detachable symmetrical structure, and a signal output interface is provided on the housing; elastic body, elastic body The elastic body is arranged in the casing, and the elastic body is in contact with the circuit hardware; the strain gauge, the strain gauge is arranged on the elastic body, and the strain gauge is electrically connected to the signal output interface. The invention solves the problem of high cost of transmission line monitoring in the prior art.

Description

technical field [0001] The invention relates to the field of power transmission lines, in particular to a monitoring front end and a monitoring device for power transmission lines. Background technique [0002] At present, most of the maintenance technologies for existing transmission lines are repair maintenance and preventive maintenance. If the line design is replaced to realize the Internet of Things, the cost is extremely high and the maintenance is extremely difficult. Therefore, it is difficult to realize the Internet of Things for transmission lines at this stage. The technical solution adopted today is to add monitoring equipment to monitor the transmission line on the basis of the existing line. In order to reduce costs, most of the monitoring equipment is integrated with the line fittings, and the parameters of the monitoring line fittings are used to obtain the transmission indirectly. Due to the working conditions of the line, since the strain edge cannot be dir...
