Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to a contact network arcing detector. Background Art

[0002] The catenary arc detector is a detection instrument based on the principle of ultraviolet light detection. When arcing occurs in the catenary, ultraviolet rays of a specific band will be generated. The catenary arc detector is installed on the roof of the vehicle and uses the ultraviolet sensor in the detection instrument to capture these ultraviolet signals. When arcing occurs, the ultraviolet sensor will receive these ultraviolet signals of a specific band and convert them into electrical signals. Then, these electrical signals will be processed and analyzed by the signal processing module.

[0003] When the overhead line arc detector is in use, the ultraviolet sensor used to capture ultraviolet signals is fixed on the roof through a bracket. Since the overhead line environment of the railway system is relatively complex, including various weather conditions and light changes, the ultraviolet sensor fixed by the bracket cannot adjust its detection angle according to environmental conditions, resulting in the arc detector being unable to adapt to different working environments, thus affecting its detection effect and stability.

[0023] In the utility model, an ultraviolet sensor 4 for receiving ultraviolet signals is arranged on the positioning plate 3. It should be noted that the ultraviolet sensor 4 adopts the model DF-ZW, and its detection spectrum range is 280-400 nanometers, which is consistent with the wavelength band of ultraviolet rays when arcing occurs. The positioning plate 3 and the support assembly 6 are arranged in a herringbone shape on the bottom plate 1, and the positioning plate 3 and the support assembly 6 are hinged. When performing detection work in different environments, the movement of the slide 52 on the guide rail 51 drives the second U-shaped frame 53 to move, so that the bottom position of the support assembly 6 hinged on the second U-shaped frame 53 is moved, and further the angle between the top of the support assembly 6 and the positioning plate 3 is changed, so that the ultraviolet sensor 4 on the positioning plate 3 can undergo a corresponding angle change, so that the environmental adaptability of the contact network arcing detector is stronger.

[0024] Specifically, refer to Figure 1 and Figure 3The guide rail 51 is provided with a plurality of positioning screw holes 54 arranged at equal intervals along its length direction, and the slide seat 52 is provided with positioning bolts 55 matched with the positioning screw holes 54. When it is necessary to adjust the angle of the ultraviolet sensor 4 on the positioning plate 3, the positioning bolts 55 are first loosened, and then the slide seat 52 is slid on the guide rail 51, thereby driving the bottom of the support assembly 6 to move, so that the angle between the top of the support assembly 6 and the positioning plate 3 changes. After adjusting the angle, the positioning bolts 55 are screwed into the positioning screw holes 54 to fix the slide seat 52 on the guide rail 51.

[0025] The adjustment assembly 5 further includes limit plates 56 disposed at both ends of the guide rail 51, and the top of the limit plates 56 is higher than the top of the guide rail 51. The limit plates 56 are used to limit the slide 52, and when the slide 52 moves on the guide rail 51, the slide 52 can be prevented from being separated from the guide rail 51. At the same time, the limit plates 56 are also used to fix the guide rail 51 on the bottom plate 1, so as to realize the installation of the guide rail 51.

[0027] The ultraviolet sensor 4 passes through the positioning plate 3 through the mounting opening 32, and a mounting plate 41 having a size larger than the mounting opening 32 is provided on the ultraviolet sensor 4, and a screw connected to the positioning plate 3 is provided on the mounting plate 41. The ultraviolet sensor 4 can be installed and removed from the positioning plate 3 through the mounting opening 32 and the mounting plate 41, so that the ultraviolet sensor 4 can be easily removed from the positioning plate 3, and the ultraviolet sensor 4 can be easily maintained and repaired.

[0028] Specifically, refer to Figure 1 A wiring port 11 is provided in the middle of the bottom plate 1, and a bolt slot 12 is provided near the top corner of the bottom plate 1. The wiring port 11 can facilitate the line connection between the ultraviolet sensor 4 and the signal processing unit inside the vehicle.
