Description

Technical Field

[0001] This utility model relates to the field of power fault diagnosis technology, and in particular to a power fault diagnosis device. Background Technology

[0002] Power fault diagnosis is the process of detecting and identifying faults such as insulation aging, poor contact, and short circuits in power systems using technical means. The core is to quickly locate the root cause of the problem and prevent the fault from escalating to the point of power outage or equipment damage. Commonly used technologies include infrared, ultrasonic, and partial discharge detection.

[0003] Infrared thermal imagers are one of the many devices used for power fault diagnosis. Their principle is to capture the infrared radiation of objects and convert it into thermal images, which can intuitively display the temperature distribution of power equipment. When equipment has faults such as excessive contact resistance or abnormal insulation, it will be accompanied by local overheating. Through thermal images, these hot spots that are invisible to the naked eye can be accurately detected, enabling early warning and troubleshooting of faults. Moreover, the detection process does not require power outages, making it highly safe.

[0004] In power system operation and maintenance, handheld infrared thermal imagers have become the core equipment for fault diagnosis of power equipment inside cabinets due to their advantages of not requiring power outages and being easy to carry. However, in actual operation, the equipment inside the cabinet is densely arranged, and power equipment is often blocked by adjacent power equipment, the metal frame inside the cabinet, or the internal support structure. This makes it impossible for handheld infrared thermal imagers to effectively capture complete thermal images, resulting in incomplete diagnostic scope, missing potential fault hazards, and significantly reducing the accuracy of diagnostic work. Utility Model Content

[0005] Therefore, it is necessary to provide a power fault diagnosis device to address the problem that handheld infrared thermal imagers cannot capture thermal images of obscured power equipment, which leads to a decrease in the accuracy of diagnostic work.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] exist Figure 1-3 In the illustrated embodiment, the present invention provides a technical solution: a power fault diagnosis device, comprising: a thermal imager body 1, which is composed of a thermal imager main body 11 and a diagnostic lens 12, wherein the diagnostic lens 12 is an infrared lens of an infrared thermal imager; and an insertion mechanism 2, which is disposed on the back of the thermal imager main body 11 and is used to insert the diagnostic lens 12 into the gap between the power equipment in the cabinet for operation.

[0019] The diagnostic insertion mechanism 2 includes: a wire storage frame 21, which is fixedly connected to the back of the thermal imager body 11; an assembly hole, which is located on the back of the wire storage frame 21 and has evenly distributed internal threads on its inner wall; a T-shaped assembly ring 22, which has evenly distributed external threads on its outer wall and is threadedly connected to the inner wall of the assembly hole, with the diagnostic lens 12 fixedly installed in the inner cavity of the T-shaped assembly ring 22; a connecting wire 23, which is located in the inner cavity of the wire storage frame 21 and is electrically connected between the thermal imager body 11 and the diagnostic lens 12, with the length of the connecting wire 23 sufficient for the diagnostic lens 12 to perform mobile diagnostic work; and a partition plate 27. A partition plate 27 is fixedly connected to the inner cavity of the wire storage frame 21 to separate the connecting wire 23 from the internal structure of the infrared thermal imager to avoid mutual interference; a wire through hole is opened on the front of the partition plate 27, and the outer wall of the connecting wire 23 is movably sleeved with the inner cavity of the wire through hole; a rotating assembly 24 is set at the bottom of the T-shaped assembly ring 22, and the rotating assembly 24 is used to facilitate the rotation of the diagnostic lens 12; a handheld assembly 25 is set at the bottom of the rotating assembly 24, and the handheld assembly 25 is used to facilitate the movement of the diagnostic lens 12; a limiting assembly 26 is set at the bottom of the handheld assembly 25, and the limiting assembly 26 is used to limit the position of the handheld assembly 25 when it is not being operated.

[0020] Specifically, the rotating assembly 24 includes: a U-shaped seat 241, which is fixedly connected to the bottom of the T-shaped assembly ring 22; and a rotating block 242, which is rotatably connected to the inner cavity of the U-shaped seat 241.

[0021] Specifically, the handheld assembly 25 includes: an inner rod 251, which is fixedly connected to the bottom of the rotating block 242; a handheld sleeve 252, which is movably sleeved on the outer wall of the inner rod 251, and the outer wall of the handheld sleeve 252 is provided with evenly distributed anti-slip textures to increase the friction between the hand and the worker's palm; two limiting grooves, which are symmetrically formed on the inner wall of the handheld sleeve 252; and two limiting sliders 254, which are symmetrically fixedly connected to the outer wall of the inner rod 251. The limiting slider 254 is slidably sleeved in the inner cavity of the corresponding limiting groove. The limiting slider 254 and the limiting groove are used to prevent the inner rod 251 from completely disengaging from the hand sleeve 252. There are two positioning holes, which are opened on one side of the inner rod 251. The number of positioning holes can be changed according to actual needs. There is a threaded hole, which is opened on one side of the hand sleeve 252. There is a positioning bolt 253, the outer wall of which is threaded to the inner wall of the threaded hole. One end of the positioning bolt 253 is movably sleeved in the inner cavity of the corresponding positioning hole.

[0022] Specifically, the limiting component 26 includes: a horizontal plate 261, which is fixedly connected to the bottom of the thermal imager body 11; a limiting insertion hole, which is opened at the bottom of the handheld sleeve 252; and a limiting plug 262, which is movably sleeved in the inner cavity of the limiting insertion hole and is fixedly connected to the top of the horizontal plate 261. When the limiting insertion hole is inserted into the limiting plug 262, the handheld sleeve 252 cannot rotate.

[0023] The specific working principle of this utility model will be explained in detail below: When electrical equipment inside the cabinet is obstructed, first turn the positioning bolt 253 counterclockwise. After the positioning bolt 253 is completely separated from the positioning hole, lift the hand sleeve 252 upwards. After the limiting insertion hole at the bottom of the hand sleeve 252 is completely separated from the limiting insertion block 262, the hand sleeve 252 drives the T-shaped assembly ring 22 to rotate counterclockwise. The counterclockwise rotating T-shaped assembly ring 22 will gradually disengage from the assembly hole. After the T-shaped assembly ring 22 is completely disengaged from the assembly hole, it applies force to the inner rod 251. The inner rod 251 is gradually disengaged from the handheld sleeve 252. When the inner rod 251 can no longer disengage from the handheld sleeve 252, the positioning bolt 253 is screwed into the corresponding positioning hole clockwise. Then, the handheld sleeve 252 can be operated to insert the diagnostic lens 12 into the gap between the electrical equipment in the cabinet for diagnostic work. When the orientation of the diagnostic lens 12 is incorrect, it can be adjusted by the U-shaped seat 241 and the rotating block 242, which solves the problem that the electrical equipment cannot be captured due to obstruction and improves the accuracy of the diagnostic work.
