Description

Technical Field

[0001] The utility model belongs to the technical field of electric power diagnosis, and in particular relates to a fault diagnosis device for intelligent power transmission and distribution. Background Art

[0002] The FH-900F distributed fault location online monitoring device for transmission lines is used. This fault monitoring terminal, installed on the three-phase conductors A, B, and C of the transmission line, can closely capture the traveling wave signal generated at the moment a fault occurs. Especially for complex power grid structures with branch lines, configuring monitoring points at branch points significantly reduces the traveling wave's location interval and attenuation, thereby improving the accuracy of fault location. This design allows the fault interval to be located to within 100 meters, significantly enhancing positioning precision.

[0003] Currently, this type of distributed fault location online monitoring device for transmission lines uses bolted connections at both ends, a practice that presents multiple operational challenges. Since installation often takes place at high altitude, installers not only need to carry and operate specialized tools, but also install at least four screws on each device, which undoubtedly increases the difficulty and complexity of the work. Faced with large-scale installation tasks, this traditional installation method is particularly cumbersome and inefficient, not only impacting work efficiency but also posing a potential threat to the safety of installers. Utility Model Content

[0004] The purpose of this utility model is to provide an intelligent fault diagnosis device for power transmission and distribution, aiming to solve the problem that the distributed fault location online monitoring device for power transmission lines of this type is provided with a bolted connection structure at both ends, which faces multiple challenges in actual operation. Given that installation operations are often carried out in high-altitude environments, installers not only need to carry and operate specific tools, but also need to install at least four screws on each device, which undoubtedly increases the difficulty and complexity of the operation. When faced with large-scale installation tasks, this traditional installation method is particularly cumbersome and inefficient, which not only affects work efficiency, but also may pose a potential threat to the safety of installers.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an intelligent fault diagnosis device for power transmission and distribution, comprising an upper body, a lower body butted against the bottom of the upper body, a cable installed between the upper body and the lower body, and a first side panel fixedly installed on the outer walls of both sides of the opening of the upper body;

[0006] A second side panel is fixedly installed on the outer walls on both sides of the opening of the lower body, and a sealing strip is connected to the bottom of the first side panel. The sealing strip is sealed with the sealing port, and the sealing port is opened on the surface of the second side panel. A buckle cover is sleeved between the first side panel and the second side panel on the same side of the upper body and the lower body.

[0007] In order to enable the first side panel to be docked with the buckle cover, as a preferred intelligent power transmission and distribution fault diagnosis device of the utility model, an upper recess is provided on the surface of the first side panel, and a convex column is fixedly connected to each of the two ends of the bottom of the first side panel, and two semicircular openings are symmetrically provided on the upper surface of the first side panel away from the side connected to the upper body.

[0008] In order to enable the second side panel to be docked with the buckle cover, as a preferred intelligent power transmission and distribution fault diagnosis device of the present invention, two sockets are symmetrically opened at both ends of the surface of the second side panel, and a lower recess is opened at the bottom of the second side panel.

[0009] The buckle cover is snap-connected with the corresponding upper notch and lower notch via two internal snap-fit strips.

[0010] In order to make the buckle cover and the first side panel more firm after docking, as a preferred intelligent power transmission and distribution fault diagnosis device of the utility model, the side structure of the buckle cover is an inverted "n" shape structure, and a clip is fixedly installed on the upper and lower inner walls of the buckle cover respectively, and a group of protrusions are installed on the upper and lower ends of the side close to the inner wall of the buckle cover respectively, and the two protrusions on the upper end of the buckle cover are docked with the semicircular opening on the first side panel, and the protrusions are made of flexible rubber material.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] When in use, the upper body and the lower body are docked, and the first side panels and the second side panels on both sides are docked. After docking, the buckle cover is slid from one end of the first side panel and the second side panel to the outer wall of the first side panel and the second side panel. In this way, after docking, the buckle cover will firmly squeeze the first side panel and the second side panel together, and then the above structure can greatly improve the convenience and efficiency of installation when installed at high altitude.
