Description

Technical Field

[0001] The invention relates to the field of infrared detection technology, in particular to an infrared thermal imager for an insulator of a live line and a use method thereof. Background Art

[0002] With the rapid development of my country's electric power industry, the scale of the power grid is constantly expanding, and the requirements for the reliability and safety of power equipment are increasing. As a key insulating component in the power system, the performance of insulators is directly related to the safe and stable operation of the power system. Therefore, the status monitoring and fault diagnosis of insulators are particularly important. Infrared thermal imaging technology is a non-contact temperature measurement method that can monitor the temperature distribution and abnormal status of objects in real time. In the field of power equipment monitoring, infrared thermal imaging technology has been widely used, especially in the fault detection of insulators, with the advantages of high efficiency, safety, reliability, and accurate judgment.

[0003] When infrared thermal imagers for live line insulators in the prior art are used, most of them are treated with anti-skid and anti-falling treatment by arranging anti-skid pads and other structures on the handle of the infrared thermal imager to increase friction. However, when inspecting insulators outdoors, the anti-skid effect is reduced in a humid environment or when the operator's hands are tired and sweaty. Due to the lack of an active anti-falling structure, when the infrared thermal imager slips from the hand, it is difficult to stop its falling process only by relying on the anti-skid pad, resulting in damage to the equipment. It is difficult to prevent the infrared thermal imager from falling, and thus the safety of the equipment and personnel cannot be ensured. Summary of the invention

The infrared thermal imager body is positioned by providing a silicone belt and a sleeve ring, thereby solving the problem of the infrared thermal imager body falling and being damaged in a humid or other environment.

[0005] The present invention is achieved through the following technical solutions:

[0015] A method for using an infrared thermal imager for an insulator of a live line comprises the following steps:

[0016] When using the infrared thermal imager to inspect the insulator of a live line, hold the handle to inspect the insulator. The infrared camera on the body cooperates with the signal processor to process the detection signal, and then the image is displayed on the display screen on the body. If the infrared thermal imager body falls, the ring will insert the adjustment part into the insertion groove and fix it with the limit block, and then use the silicone belt to position the infrared thermal imager body to actively prevent it from falling off.

[0031] See also Figure 1-7The present invention provides a technical solution: an infrared thermal imager for an insulator of a live line, comprising an infrared thermal imager body 1 and a dust block 2, the infrared thermal imager body 1 having a handle 101 and a body 106, the body 106 being arranged on the handle 101, a socket 103 being provided at the bottom of the handle 101, the socket 103 being connected to a reserved slot 104, the dust block 2 being located in the socket 103, when charging the infrared thermal imager body 1, a plug is inserted through the socket 103, and after charging is completed, the dust block 2 protects the socket 103 from dust, and an anti-slip pad 1 is installed on the outer surface of the handle 101 02, the anti-skid pad 102 is a rubber pad. The anti-skid pad 102 can increase the friction between the operator and the handle 101 when the operator holds the handle 101, thereby reducing the risk of slipping. A silicone belt 6 is provided on the handle 101, and a ring 7 is connected to the end of the silicone belt 6. A rectangular block 8 is installed on the ring 7. A moving groove 802 is provided in the rectangular block 8. A limited block 9 is slidably matched in the moving groove 802. A pull rod 11 is installed on the outer surface of the limit block 9. A protrusion 1101 is installed at the end of the pull rod 11. A first sliding groove is provided on the rectangular block 8. The pull rod 11 is slidably matched. In the first slide groove, through the provided pull rod 11, when taking the limit block 9 out from the limit opening 704, it is only necessary to pull the protrusion 1101 to drive the pull rod 11 to move, so as to drive the limit block 9 to move out from the limit opening 704. A first spring 10 is connected between the limit block 9 and the inner wall of the movable groove 802. The collar 7 has a mounting portion 701, and an adjusting portion 702 is provided at the end of the mounting portion 701.
