Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to an intelligent porcelain insulator with integrated temperature and humidity sensing. Background Technology

[0002] Porcelain insulators are commonly used insulating components in power systems, widely applied in transmission lines, substations, and other locations. Their performance directly affects the safe and stable operation of the power system. However, changes in the ambient temperature and humidity of the environment in which porcelain insulators are located can significantly impact their insulation performance. In high-temperature and high-humidity environments, the surface of porcelain insulators is prone to dirt accumulation and moisture absorption, leading to a decrease in their insulation resistance and even causing faults such as flashover.

[0003] Currently, the condition monitoring of porcelain insulators mainly relies on manual inspections, which is not only labor-intensive and inefficient, but also makes it difficult to grasp the real-time temperature and humidity changes of the environment in which the porcelain insulators are located, thus failing to detect potential faults in a timely manner. Therefore, there is a need for an intelligent porcelain insulator that can integrate temperature and humidity sensing functions to achieve real-time monitoring of the temperature and humidity of its surrounding environment, thereby improving the safety and reliability of power system operation.

[0023] 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.

[0024] Please see Figure 1-6 The present invention provides a technical solution: an intelligent porcelain insulator with integrated temperature and humidity sensing, including a porcelain insulator body 1, an upper fitting 2 on the top of the porcelain insulator body 1, a lower fitting 3 on the bottom, and a temperature and humidity sensor 5 embedded in the skirt 4 of the porcelain insulator body 1.

[0025] Furthermore, both the upper fitting 2 and the lower fitting 3 are coated with an anti-corrosion coating, and both have internal reinforcing ribs arranged in a mesh structure. The anti-corrosion coating improves the corrosion resistance of the upper fitting 2 and the lower fitting 3, extending their service life; the mesh-structured reinforcing ribs enhance the structural strength of the upper fitting 2 and the lower fitting 3, improving their load-bearing capacity and stability.

[0026] Furthermore, connecting protrusions are provided at the top and bottom of the porcelain insulator body 1, and connecting protrusions are also provided inside the upper fitting 2 and lower fitting 3. The connecting protrusions between the upper fitting 2 and lower fitting 3 and the porcelain insulator body 1 are staggered and sealed by the cement layer 13. The cement layer 13 makes the connection between the upper fitting 2, lower fitting 3 and the porcelain insulator body 1 more secure, and also enhances the sealing of the connection, preventing moisture, dust, etc. from entering and affecting the insulation performance of the porcelain insulator.

[0027] Furthermore, the temperature and humidity sensor 5 is a waterproof sensor, and its sensing probe is exposed on the surface of the skirt 4, with a self-cleaning coating on the probe. An insulating pad is placed between the temperature and humidity sensor 5 and the skirt 4. The self-cleaning coating reduces the adhesion of dust and other debris to the sensing probe, ensuring detection accuracy while reducing the frequency of manual cleaning. The electromagnetic shielding layer effectively blocks interference from the electric field on the temperature and humidity sensor 5, and the insulating pad further enhances the insulation performance between the temperature and humidity sensor 5 and the porcelain insulator body 1, reducing the influence of the electric field.

[0028] Furthermore, the porcelain insulator body 1 has a through-type conductor storage groove 8, in which the conductor 6 is embedded. The conductor 6 is wrapped with an insulating protective sleeve, which has a double-layer structure: an inner polytetrafluoroethylene (PTFE) insulation layer and an outer metal shielding mesh. The conductor storage groove 8 is equipped with fixing clips 14 for organizing the conductor 6, and these clips are made of insulating material. The conductor storage groove 8 and the fixing clips 14 can organize and fix the conductor 6 in an orderly manner, preventing the conductor 6 from being randomly distributed inside the porcelain insulator body 1, preventing mutual interference between conductors 6 or damage caused by shaking, and ensuring the stability of signal transmission. In the double-layer insulating protective sleeve, the PTFE insulation layer has excellent insulation performance, the metal shielding mesh can effectively shield the electric field from interfering with the signal transmitted in the conductor 6, and the fixing clips 14 made of insulating material can also reduce the influence of electric field conduction.

[0029] The temperature and humidity sensor 5 is connected to the data processing module 7 via the wire 6. The data processing module 7 is connected to the wireless transmission module via the wire 6. The wireless transmission module is installed on the tower, away from the working position of the porcelain insulator, so that the operation of the wireless transmission module will not be affected by the high voltage electric field.

[0030] Furthermore, the data processing module 7 is housed within the sealed box 10, which is fixedly mounted on the lower fitting 3 via a mounting bracket 11. The sealed box 10 is made of a metal shielding material. The sealed box 10, made of metal shielding material, forms a double shield with the electromagnetic shielding layer outside the electronic components, which can significantly reduce the interference of the electric field on the data processing module 7.

[0031] The upper hardware 2 is equipped with a power supply module, which is electrically connected to the temperature and humidity sensor 5, the data processing module 7 and the wireless transmission module respectively; the temperature and humidity sensor 5 and the data processing module 7 are both wrapped with an electromagnetic shielding layer.

[0032] Furthermore, the power supply module is a solar power supply module, including a solar panel 9 and a battery 12. The solar panel 9 is mounted on the upper fitting 2 via a fixing bracket 11, and the battery 12 is located inside the upper fitting 2, with an insulation sleeve covering the outside of the battery 12. An electromagnetic interference (EMI) filter is included in the circuit of the power supply module. The solar panel 9, mounted via the fixing bracket 11, allows for position and angle adjustment, improving the utilization rate of solar energy. The insulation sleeve provides insulation for the battery 12 in low-temperature environments, ensuring its normal operating performance and guaranteeing power supply stability. The EMI filter effectively suppresses interference from the electric field through the power supply line to the power supply module and other electronic components, ensuring stable power supply.

[0033] Specifically, the sensing probe of the temperature and humidity sensor 5 is kept clean by the self-cleaning coating and avoids electric field interference by the electromagnetic shielding layer and the insulating pad. It detects the temperature and humidity information of the environment where the porcelain insulator is located in real time and transmits the information to the data processing module 7 through the wire storage groove 8, which is fixed by the fixing buckle 14 made of insulating material. The polytetrafluoroethylene insulation layer and metal shielding mesh on the outer layer of the wire 6 further prevent the electric field from interfering with the signal transmission.

[0034] The data processing module 7 is effectively protected from electric field interference by the double shielding of its external electromagnetic shielding layer and the sealed box 10 made of metal shielding material. After processing the information, the data processing module 7 sends it to the remote monitoring center through the wireless transmission module.

[0035] In the power supply module, the solar panel 9, with its installation angle adjusted by the fixing mounting piece 11, efficiently absorbs solar energy and converts it into electrical energy, which is stored in the battery 12 with an insulated sleeve. The electromagnetic interference filter in the circuit suppresses electric field interference, providing a stable power supply to the various electronic components. The upper fitting 2 and lower fitting 3 achieve a firm and sealed connection with the porcelain insulator body 1 through the cooperation of the connecting protrusion and the cement layer 13. The anti-corrosion coating and the mesh reinforcing ribs ensure the service life and structural strength of the fittings.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
