Description

Technical Field

[0001] This utility model relates to the field of wind power transformer pipeline protection technology, specifically to an insulating wrapping structure for wind power transformer insulating oil pipelines that prevents leakage. Background Technology

[0002] Wind turbine transformers are key equipment for stepping up and converting the electrical energy generated by wind turbines. They are mainly used to convert low-voltage electrical energy into high-voltage electrical energy to facilitate power transmission and distribution. The transformer insulating oil plays an important role in insulation, heat dissipation, and arc suppression, ensuring the safe and stable operation of the transformer.

[0003] The insulating wrapping structure of the insulating oil pipelines in wind turbine transformers is primarily intended to prevent creepage caused by condensation or contamination on the pipeline surface, and also provides insulation, moisture protection, and UV protection, ensuring stable operation of the transformer in the harsh wind farm environment. However, the seams and overlaps of traditional tape wrapping are weak points. Under long-term vibration and temperature changes, these seams may loosen or develop tiny gaps. Moisture can seep in through these gaps and condense into water droplets in the gaps between the metal pipes and the insulation layer, creating a path for creepage and defeating the purpose of insulation.

[0004] There is an urgent need for a leak-proof insulation wrapping structure for the insulating oil pipeline of wind power transformers to solve the technical defects mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a leak-proof insulation wrapping structure for the insulating oil pipeline of a wind power transformer, in order to solve the problem of loose joints and easy leakage mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a leak-proof insulating wrapping structure for insulating oil pipelines of wind power transformers, comprising a pipeline body, an anti-seepage sleeve fixedly installed on the outside of the pipeline body, sealing components installed on both sides of the anti-seepage sleeve, the sealing components including sealing sleeves, connecting sleeves fixedly connected to the sides of the sealing sleeves, a heat insulation component detachably installed on the outside of the anti-seepage sleeve, the heat insulation component including a heat insulation sleeve, and a protective component fixedly installed on the outside of the heat insulation component.

[0007] As a further technical solution of this utility model, the seepage-proof sleeve is made of polyolefin heat shrink tubing and is fixed to the outside of the pipe body by heat shrinking, and the insulation sleeve is semi-circular and covers the outside of the seepage-proof sleeve.

[0008] As a further technical solution of this utility model, the sealing assembly includes a mounting bolt, which is threaded onto the outside of the connecting sleeve. A sealing ring is fixedly connected to the inside of the sealing sleeve, and a water-absorbing expansion ring is fixedly connected to the inside of the connecting sleeve.

[0009] As a further technical solution of this utility model, the front and rear ends of the insulation sleeve are fixedly connected to connecting plates, and connecting bolts are provided on the connecting plates.

[0010] As a further technical solution of this utility model, the insulation sleeve is provided in two sets, and the connecting plate is fixedly connected by connecting bolts.

[0011] As a further technical solution of this utility model, the protective component includes a protective plate, the outer surface of which is provided with an anti-ultraviolet coating, and a shock-absorbing pad is fixedly connected between the protective plate and the insulation sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the leak-proof insulating oil pipeline insulation wrapping structure of the wind power transformer not only achieves the function of preventing water droplets from seeping in from the joints and achieving the function of enhancing heat preservation, but also achieves the function of enhancing protection.

[0013] The pipeline is equipped with sealing components, sealing sleeves, connecting sleeves, mounting bolts, sealing rings, water-absorbing expansion rings, and anti-seepage sleeves. The anti-seepage sleeve is made of polyolefin heat shrink tubing, which shrinks tightly after heating to form an integrated, seamless sealing layer. At the same time, sealing components are installed at the interface between the pipeline body and the anti-seepage sleeve. The sealing sleeves and connecting sleeves on the sealing components fit tightly against the outer wall of the pipeline body. The sealing rings and water-absorbing expansion rings achieve a sealing effect to prevent gaps and prevent external water droplets from leaking in from the gaps and affecting safety.

[0014] By incorporating insulation components, insulation sleeves, connecting plates, and connecting bolts, the insulation components on the outside of the pipeline body can ensure the normal delivery of insulating oil in low-temperature environments. The insulation sleeve, made of high-insulation material, is tightly fitted over the outside of the seepage-proof pipe sleeve to provide insulation and protection for the pipeline body. During installation, two sets of insulation sleeves need to be fitted over the outside of the seepage-proof pipe sleeve and fixed with connecting bolts. This structure achieves the function of enhancing the insulation effect.

[0015] By incorporating protective components, protective plates, UV-resistant coatings, and shock-absorbing pads, the outermost protective components of the pipeline transporting insulating oil enhance the pipeline's impact resistance. The protective plates on the protective components can directly contact external impactors. The rubber shock-absorbing pads between the protective plates and the insulation sleeve absorb most of the impact force, reducing impact damage to the pipeline body. The UV-resistant coating on the outermost part of the protective plates blocks most ultraviolet rays, preventing the shock-absorbing pads from aging, becoming brittle, and losing their insulation and protective functions. This structure achieves enhanced protection. Attached Figure Description

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.

[0022] Please see Figure 1-4 An embodiment of this utility model provides: a leak-proof insulating wrapping structure for insulating oil pipelines of wind power transformers, including a pipeline body 1, an anti-seepage sleeve 3 fixedly installed on the outside of the pipeline body 1, sealing components 2 installed on both sides of the anti-seepage sleeve 3, the sealing components 2 including a sealing sleeve 201, a connecting sleeve 202 fixedly connected to the side of the sealing sleeve 201, and a heat insulation component 4 detachably installed on the outside of the anti-seepage sleeve 3, the heat insulation component 4 including a heat insulation sleeve 401, and a protective component 5 fixedly installed on the outside of the heat insulation component 4;

[0023] The seepage-proof sleeve 3 is made of polyolefin heat shrink tubing and is fixed to the outside of the pipe body 1 by heat shrinking. The insulation sleeve 401 is semi-circular and covers the outside of the seepage-proof sleeve 3. The sealing component 2 includes mounting bolts 203, which are threaded on the outside of the connecting sleeve 202. A sealing ring 204 is fixedly connected to the inside of the sealing sleeve 201, and a water-absorbing expansion ring 205 is fixedly connected to the inside of the connecting sleeve 202.

[0024] Specifically, such as Figure 1 and Figure 3As shown, the anti-seepage sleeve 3 is made of polyolefin heat shrink tubing. This material shrinks tightly after heating to form an integrated, seamless sealing layer. At the same time, a sealing component 2 is installed at the interface between the pipe body 1 and the anti-seepage sleeve 3. The sealing sleeve 201 and the connecting sleeve 202 on the sealing component 2 are tightly fitted to the outer wall of the pipe body 1. The sealing ring 204 and the water-absorbing expansion ring 205 achieve a sealing effect to avoid gaps and prevent external water droplets from seeping in from the gaps and affecting safety.

[0025] The front and rear ends of the insulation sleeve 401 are fixedly connected to the connecting plate 402. The connecting plate 402 is provided with the connecting bolt 403. The insulation sleeve 401 is provided with two sets of connecting plates 402, which are fixedly connected by the connecting bolt 403.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the insulation component 4 outside the main body of the pipeline 1 can ensure the normal delivery of insulating oil in a low-temperature environment. The insulation sleeve 401 is made of high-insulation material and is tightly fitted on the outside of the anti-seepage pipe sleeve 3 to provide insulation protection for the main body of the pipeline 1. During installation, two sets of insulation sleeves 401 need to be fitted on the outside of the anti-seepage pipe sleeve 3 and fixed with connecting bolts 403.

[0027] The protective component 5 includes a protective plate 501, the outer surface of which is provided with an anti-ultraviolet coating 502, and a shock-absorbing pad 503 is fixedly connected between the protective plate 501 and the insulation sleeve 401.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the protective component 5 installed on the outermost part of the pipeline body 1 for transporting insulating oil can improve the pipeline's impact protection. The protective plate 501 on the protective component 5 can directly contact external impacting objects. The shock-absorbing pad 503 between the protective plate 501 and the insulation sleeve 401 is made of rubber shock-absorbing block, which can absorb most of the impact force and reduce the impact damage to the pipeline body 1. The ultraviolet-proof coating 502 on the outermost part of the protective plate 501 can block most ultraviolet rays and prevent the shock-absorbing pad 503 from aging, becoming brittle, and losing its insulation and protective functions.

[0029] Working Principle: A seepage-proof sleeve 3 can be installed on the outside of the main pipe 1 used to transport insulating oil to wind turbine transformers. The seepage-proof sleeve 3 is made of polyolefin heat-shrink tubing, which shrinks tightly after heating to form a seamless, integrated sealing layer. Simultaneously, a sealing component 2 is installed at the interface between the main pipe 1 and the seepage-proof sleeve 3. The sealing sleeve 201 and connecting sleeve 202 on the sealing component 2 fit tightly against the outer wall of the main pipe 1. The sealing ring 204 and water-absorbing expansion ring 205 achieve a sealing effect, preventing gaps and ensuring safety by preventing external water droplets from leaking in. The insulation component 4 on the outside of the main pipe 1 ensures normal delivery of insulating oil even in low-temperature environments. The insulation sleeve 401 is made of high-insulation material and fits tightly. Outside the seepage-proof sleeve 3, the main body of the pipeline 1 is insulated and protected. During installation, two sets of insulation sleeves 401 are placed on the outside of the seepage-proof sleeve 3 and fixed with connecting bolts 403. The outermost protective component 5 installed on the main body of the pipeline 1 transporting insulating oil can improve the pipeline's impact protection. The protective plate 501 on the protective component 5 can directly contact external impact objects. The shock-absorbing pad 503 between the protective plate 501 and the insulation sleeve 401 is made of rubber shock-absorbing block, which can absorb most of the impact force and reduce the impact damage to the main body of the pipeline 1. The ultraviolet-proof coating 502 on the outermost part of the protective plate 501 can block most ultraviolet rays and prevent the shock-absorbing pad 503 from aging, becoming brittle and losing its insulation and protective functions. This structure realizes the function of enhanced protection.
