[0002] Large high-voltage power equipment such as generators, transformers and motors will generate heat during operation. Excessive temperature will cause equipment failure and may lead to safety accidents. In order to effectively and timely monitor the heat source inside the equipment, the sensor required to detect the temperature needs to be placed inside the equipment. To complete the above function, the current practice is usually to clamp a section of hard insulation structure at the top of the flexible cable, and then bury the hard insulation structure inside the equipment, but once the sensor is damaged, it cannot be removed.

[0003] After searching, Chinese patent announcement number: CN218631520U discloses an insulating guide sleeve for high-temperature scenarios. This solution adopts the method of first burying the sleeve in a hard insulator and then inserting the sensor, thereby solving the problem of difficulty in replacing the sensor after it is damaged. However, during layout, the guide sleeve with a hard insulator is installed inside the equipment, and the joint between the hard insulator and the guide sleeve is prone to bending and deformation. After deformation, the sensor will be unable to be removed or inserted.

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] See also Figure 1-Figure 4 The present embodiment provides a protective structure for strengthening the bending strength of the joint position between the sleeve and the main body, including a hard insulator main body 2, a guide sleeve 3 and a protective structure 1. The guide sleeve 3 is provided with a through hole for guiding the sensor to penetrate, and a mounting hole is provided on one side of the hard insulator main body 2. One end of the guide sleeve 3 is installed in the mounting hole. The protective structure 1 is placed at the joint position between the hard insulator main body 2 and the guide sleeve 3, and is used to improve the bending resistance of the guide sleeve 3 at the position where it is led out from the hard insulator main body 2. It has good mechanical properties and can achieve good protection effects in protecting specific areas, so that the objects wrapped by it can adapt to extreme working conditions.

[0028] As one of the embodiments of this invention, Figure 2 and Figure 3 As shown, the protective structure 1 includes a support member 11 and a shrinkage protection sleeve 12. The support member 11 is placed on the outside of the guide sleeve 3. The support member 11 is preferably one or two. The support member 11 is placed on one side or both sides of the guide sleeve 3 to strengthen the strength of the guide sleeve 3. The shrinkage protection sleeve 12 is sleeved on the outside of the support member 11 to wrap the support member 11 and the guide sleeve 3 into one body. The support member 11 and the shrinkage protection sleeve 12 are partially placed in the mounting hole of the hard insulator body 2.

[0029] In this embodiment, the support member 11 is a bendable rod or thick-walled tube with a certain supporting force. The material of the support member 11 needs to have good mechanical properties, temperature resistance, wear resistance, and fatigue resistance. In the field of electricity, insulation and pressure resistance must also be considered. The material of the support member 11 is preferably PEEK, and PI, carbon fiber, PTFE or FEP can also be selected.

[0030] In this embodiment, the shrinkable protective sleeve 12 is a sleeve with heat shrinkage and non-stickiness. The material of the shrinkable protective sleeve 12 needs to be resistant to high temperature, pressure, wear, excellent electrical insulation and good mechanical properties. The non-stickiness of the shrinkable protective sleeve 12 makes the shrinkable protective sleeve 12 have anti-pollution flashover characteristics. The heat shrinkage of the shrinkable protective sleeve 12 can completely fix the support member 11 on the outside of the sleeve 3 by high-temperature heat shrinkage, thereby improving the stability of the connection. The material of the shrinkable protective sleeve 12 is FEP, and silicone rubber, PTFE or PVDF can also be selected.

[0031] In this embodiment, the shrink protective sleeve 12 is used to wrap the support member 11, and the support member 11 buried in the hard insulator body 2 does not need to be completely covered, which is conducive to fixing the shrink protective sleeve 12 and the support member 11 in the hard insulator body 2, and increasing the tensile resistance of the protective structure 1 inside the hard insulator body 2.

[0032] In this embodiment, the shrink protective sleeve 12 completely covers the support member 11 outside the hard insulator body 2, preventing the support member 11 from being exposed and falling off outside the hard insulator body 2, which would cause the hard-soft joint part between the hard insulator body 2 and the guide sleeve 3 to be easily bent and deformed during arrangement, making it impossible to remove or insert the sensor.

[0033] In this embodiment, the support member 11 is relatively arranged between the guide sleeve 3 and the tightening protective sleeve 12. According to the position of the fixed protective structure 1 in the internal mounting hole of the hard insulator body 2, the fixed position of the support member 11 is marked at the distance from the top of the guide sleeve 3 buried in the hard insulator body 2. The support member 11 is placed on both sides or one side of the guide sleeve 3 to facilitate determining the installation position of the support member 11.

[0034] In this embodiment, the shrink protective sleeve 12 completely fixes the support member 11 on both sides or one side of the guide sleeve 3 by high-temperature heat shrinkage. The top of the guide sleeve 3 is placed in the internal mounting hole of the hard insulator body 2 as a standard, and the joint position of the protective structure 1 and the hard insulator body 2 is marked to facilitate the later fixation of the guide sleeve 3.

[0035] In one example, the protective structure 1 of the present invention can also be used to improve the strength of the outlet position of a non-tube structure (such as an optical cable 4). Figure 5 As shown, it is a conventional pad-type optical fiber temperature sensor used for temperature measurement between layers of generator stator wire rods. The protective structure 1 of the utility model can be set at the combination position of the optical cable 4 and the hard insulator body 2 in the same way as the method of the above embodiment, which can effectively improve the bending resistance of the optical cable 4 at the position where it is led out from the hard insulator body 2.

[0036] The technical solution provided by the utility model is to install a protective structure 1 at the junction of the hard insulator body 2 and the guide sleeve 3, thereby enhancing the bending resistance of the junction of the hard insulator body 2 and the guide sleeve 3 in the temperature sensing area of ​​the sensor, or objects under the same type of conditions, so as not to be damaged during installation, equipment operation and transportation. At the same time, it also has temperature resistance, wear resistance, pollution flashover resistance, excellent electrical insulation and good mechanical properties, and can achieve good protection effects in protecting specific areas, so that the objects wrapped therein can adapt to extreme working conditions.

[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
