In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0051] The embodiments of this utility model will be described in detail below.

[0052] Example 1

[0053] See Figures 1-2 This embodiment provides a multispectral electrical equipment 9 monitoring device, including a housing 1 and a beam splitter 2, an infrared filter 3, an infrared detector 4, an ultraviolet filter 5 and an ultraviolet detector 6 located inside the housing 1.

[0054] The housing 1 is made of light-shielding material, and one side of the housing 1 has a light-entry window 11. The housing 1 is connected to a mounting bracket 7.

[0055] The beam splitter 2 is tilted relative to the light inlet window 11. The beam splitter 2 is located between the infrared filter 3 and the light inlet window 11. The beam splitter 2 is used to transmit infrared light and reflect ultraviolet light.

[0056] The infrared filter 3 is located between the infrared detector 4 and the beam splitter 2; the infrared filter 3 is a bandpass infrared filter 3 with a working wavelength range of 8~14μm, which can shield non-thermal radiation bands.

[0057] Infrared detector 4 is used to detect thermal radiation. The photosensitive surface, infrared filter 3, and light-entry window 11 of infrared detector 4 are parallel to each other.

[0058] The ultraviolet filter 5 is located between the ultraviolet detector 6 and the beam splitter 2, and the ultraviolet filter 5 is perpendicular to the light-entry window 11. The ultraviolet filter 5 is a solar-blind ultraviolet filter 5, and its working wavelength range is 240~280nm, which can suppress visible light interference.

[0059] The ultraviolet detector 6 is a photon counting type; the photosensitive surface of the ultraviolet detector 6 and the ultraviolet filter 5 are parallel to each other, and the two and the light-entry window 11 are located on the same side of the beam splitter 2.

[0060] Light enters the housing 1 through the light inlet window 11 and illuminates the beam splitter 2. Infrared light first passes through the beam splitter 2, then through the infrared filter 3, and finally illuminates the photosensitive surface of the infrared detector 4. Ultraviolet light is first reflected by the beam splitter 2, then through the ultraviolet filter 5, and finally illuminates the photosensitive surface of the ultraviolet detector 6. When electrical equipment 9 has insulation defects, corona discharge and surface partial discharge phenomena occur. The defect will radiate a large amount of ultraviolet light. The ultraviolet detector 6 detects the solar-blind ultraviolet band (240~280nm) of corona discharge radiation. By detecting the number of ultraviolet photons emitted, it indirectly assesses the insulation status of the operating equipment, enabling the early detection of insulation defects. As the defect further develops, an abnormal temperature rise occurs at the defect location, resulting in a thermal fault that radiates a large amount of infrared light. The infrared detector 4 can promptly detect this thermal fault.

[0061] Based on the characteristics of defects caused by aging and damage at different development stages, this embodiment adopts a combination of infrared and ultraviolet monitoring methods to monitor the status of electrical equipment 9 more comprehensively and timely, which is more conducive to the timely maintenance of electrical equipment 9.

[0062] Example 2

[0063] The adjustable pitch angle of the bracket in the existing technology can significantly expand the monitoring range to monitor more devices, but there are blind spots in the monitoring of individual devices. For example, the monitoring effect of different sides of a single device varies greatly, and some sides are not monitored.

[0064] Therefore, this embodiment provides a specific implementation of the mounting bracket 7 in Embodiment 1.

[0065] See Figures 1-3 The mounting frame 7 includes a hanging plate 71, a rotating table 72, an arc plate 73, a first winding wheel 74, and a slider 75.

[0066] The hanging plate 71 is used to hoist the multispectral electrical equipment 9 monitoring device, and the hanging plate 71 is fixed by bolts.

[0067] The rotary table 72 is rotatably connected to the lower side of the hanging plate 71 via the first rotating shaft 721, and the first rotating shaft 721 is connected to the first motor 722 via a belt and pulley.

[0068] The arc plate 73 is arched, and its upper middle part is connected to the lower side of the rotary table 72 through the connector 731.

[0069] The first take-up roller 74 is rotatably connected to the arc plate 73 via the second rotating shaft 741. The first take-up roller 74 is provided at both the left and right ends of the arc plate 73.

[0070] The slider 75 is slidably connected to the lower side of the arc plate 73, and both ends of the slider 75 are connected to a first winding wheel 74 via a first connecting rope 76. The housing 1 is fastened to the lower side of the slider 75 by bolts.

[0071] The rotary table 72 can drive the arc plate 73 and the housing 1 to reciprocate on the horizontal plane; the slider 75 can drive the housing 1 to reciprocate on the vertical plane. When the slider 75 drives the housing 1 to reciprocate on the vertical plane, the two first take-up wheels 74 rotate in the same direction and at the same speed. The slider 75 is pulled left and right in a take-up and release manner to adjust the relative position of the light-inlet window 11 on the housing 1 and the electrical equipment 9, so that the light-inlet window 11 can face multiple sides of the electrical equipment 9, thereby receiving light from multiple sides of the electrical equipment 9, so as to reduce the monitoring blind spot of a single device.

[0072] The mounting frame 7 also includes a limiting wheel 77, which is located on the upper side of the arc-shaped plate 73 and close to the first winding wheel 74. The first connecting rope 76 is attached to the limiting wheel 77. By setting the limiting wheel 77, the first connecting rope 76 can be positioned entirely above the arc-shaped plate 73, leaving more room for movement below the arc-shaped plate 73.

[0073] Mounting frame 7 also includes a second take-up reel 78, a third shaft 79, a third take-up reel 81, and a second connecting rope 82.

[0074] Two second take-up rollers 78 are located at both ends of the arc plate 73; the second take-up rollers 78 are mounted on the second rotating shaft 741, and the second take-up rollers 78 can drive the first take-up roller 74 to rotate through the second rotating shaft 741.

[0075] The third shaft 79 is located above the middle of the two second take-up reels 78, and the third shaft 79 is mounted on the connector 731.

[0076] Two third winding reels 81 are mounted on the third shaft 79.

[0077] One end of the second connecting rope 82 is wound around the second winding reel 78, and the other end is wound around the third winding reel 81.

[0078] The third rotating shaft 79 is connected to a second motor (not shown in the figure); when the third rotating shaft 79 rotates, the two second rotating shafts 78 are driven to rotate in the same direction and at the same speed through the transmission of the third winding wheel 81 and the second connecting rope 82, so that the two first winding wheels 74 are rotated in the same direction and at the same speed through the two second rotating shafts 741. The slider 75 is pulled left and right in a winding and unwinding manner to adjust the relative position of the light window 11 on the housing 1 and the electrical equipment 9.

[0079] Finally, it should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
