Description

Technical Field

[0001] This application relates to the technical field of power transformers, and in particular to a transformer with waterproof properties. Background Technology

[0002] A transformer is a static electrical device used to transform alternating current voltage and current to transmit alternating current electrical energy. It achieves electrical energy transfer based on the principle of electromagnetic induction. Transformers can be classified according to their uses into power transformers, testing transformers, instrument transformers, and special-purpose transformers: power transformers are essential equipment for power transmission and distribution, and power distribution to users; testing transformers are used to perform withstand voltage (step-up) tests on electrical equipment; instrument transformers are used for electrical measurement and relay protection (PT, CT) in power distribution systems; special-purpose transformers include electric furnace transformers for metallurgy, welding transformers, rectifier transformers for electrolysis, and small voltage regulating transformers, etc.

[0003] In existing technologies, some solutions for waterproofing use simple external covering structures, which can block some rainwater, but are difficult to deal with water vapor penetration or water retention, and may also hinder heat dissipation; while heat dissipation designs mostly rely on a single heat sink or fan, which can easily lead to a decrease in heat dissipation efficiency due to the enclosed structure in humid environments.

[0004] Therefore, a waterproof transformer can prevent rainwater from entering and drain quickly through a multi-level waterproof structure, and improve heat dissipation efficiency through multi-level heat conduction and air convection, thereby ensuring stable operation of the equipment and extending its service life.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] 1. This utility model, by setting up components such as a canopy, a water baffle, drainage holes, and a protective plate, and through the cooperation between the canopy and the water baffle, allows the canopy to guide and divert rainwater through its inclined structure, the water baffle to effectively prevent rainwater from entering, and if water enters the drainage holes, the accumulated water is quickly discharged.

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a transformer with waterproof properties. For example... Figure 1 As shown, the transformer body 1 is provided with a waterproof structure 3, and a heat dissipation structure 2 is provided in the middle of the waterproof structure 3;

[0027] The heat dissipation structure 2 includes a heat conduction plate 203, a heat dissipation pipe 202 is fixedly installed on the outside of the heat conduction plate 203, and a heat dissipation fin 201 is fixedly installed on the outside of the heat dissipation pipe 202.

[0028] The waterproof structure 3 includes a canopy 301, a water baffle 303 is provided below the canopy 301, a protective plate 304 is provided behind the water baffle 303, and a drainage hole 302 is provided on one side of the protective plate 304.

[0029] It should be noted that heat dissipation structure 2 directly contacts the heat-generating components through heat-conducting plate 203, transferring internal heat to the external heat dissipation pipe 202. The heat sink 201 then increases the surface area, utilizing air convection to achieve multi-stage, efficient heat dissipation, ensuring effective cooling of the transformer even in a sealed environment. Waterproof structure 3 uses a roof 301 to block external rainwater, a water baffle 303 to prevent water from entering the interior, a protective plate 304 to further prevent moisture penetration, and drainage holes 302 to quickly drain accumulated water. These structures work together to prevent moisture retention and intrusion, ensuring the dryness of internal components. These two structures complement each other, solving the waterproofing problem in humid environments while maintaining efficient heat dissipation, thereby improving the transformer's stability and service life.

[0030] Please see Figures 1-4 The transformer body 1 includes a base 102, an insulating barrel 101 is fixedly installed on the base 102, and an insulator 103 is provided above the insulating barrel 101.

[0031] It should be noted that the base 102 is used to stably support the overall equipment and ensure the stability of the installation; the insulating bucket 101 is fixed on the base 102 and mainly serves as an insulating container for internal electrical components such as coils and iron cores, preventing current leakage and providing basic protection; the insulator 103 is located above the insulating bucket 101 and is used to support and connect high-voltage components, while enhancing insulation performance, blocking current conduction through the external structure, and ensuring the safe operation of the equipment in humid or high-humidity environments.

[0032] Please see Figures 1-4 A heat-conducting plate 203 is fixedly installed above the base 102, and a canopy 301 is fixedly installed above the heat-conducting plate 203.

[0033] It should be noted that the heat-conducting plate 203 transfers heat from inside the transformer to the heat dissipation structure 2, while the canopy 301 forms a waterproof barrier to prevent direct rainwater intrusion. The heat-conducting plate 203 both supports the waterproof structure 3 of the canopy 301 and ensures that heat is conducted upwards from the base 102 to the heat dissipation components, balancing heat dissipation efficiency and waterproof performance. The fixed connection between the canopy 301 and the heat-conducting plate 203 must be sealed or have an inclined structure to prevent water seepage, achieving a synergistic effect of waterproofing and heat dissipation.

[0034] Please see Figures 1-5 The drainage hole 302 is located between the baffle plate 303 and the protective plate 304.

[0035] It should be noted that the function of the drainage hole 302, located between the baffle plate 303 and the protective plate 304, is to quickly drain any rainwater or condensate that may accumulate between the baffle plate 303 and the protective plate 304, preventing moisture retention and seepage into the transformer. Its design, combining the inclined structure of the baffle plate 303 and the barrier function of the protective plate 304, effectively blocks external rainwater from entering and prevents moisture from seeping in through the gap, ensuring the stable operation of the transformer in a humid environment.

[0036] Please see Figures 1-4 The heat pipe 202 is filled with a heat-conducting medium.

[0037] It should be noted that the heat-conducting medium filled inside the heat pipe 202 enhances the heat conduction efficiency, quickly transferring the heat generated by the heat-generating components of the transformer to the outer wall of the heat pipe 202 and the heat sink 201, effectively improving heat dissipation performance, avoiding local overheating, and ensuring that the transformer maintains stable operation while being waterproof.

[0038] Please see Figures 1-5 The water baffle 303 has an inclined structure.

[0039] It should be noted that the inclined structure of the water baffle 303 prevents rainwater from entering and directly intruding into the internal components, thus preventing moisture penetration. This design optimizes the waterproofing efficiency of the waterproof structure 3, enhances the protection of the transformer, and ensures its stable operation in humid or outdoor environments.

[0040] Please see Figures 2-4 The heat-conducting plate 203 is in direct contact with the heat-generating components of the transformer body 1.

[0041] It should be noted that the heat-conducting plate 203 and the transformer body 1 establish an efficient heat conduction path through direct contact, which quickly transfers the heat generated by the heat-generating components to the heat-conducting plate 203. Then, the heat is dissipated in multiple stages through the heat dissipation pipe 202 and the heat sink 201, which significantly improves the heat dissipation efficiency and ensures that the transformer temperature can still be effectively controlled under the sealed waterproof structure 3, thereby ensuring the stable operation and service life of the equipment in a humid environment.

[0042] The implementation principle of a waterproof transformer according to an embodiment of this application is as follows: The heat dissipation structure 2 adopts a multi-stage heat conduction and air convection mechanism. The heat conduction plate 203 directly contacts the heat-generating components of the transformer, efficiently conducting heat to the heat dissipation pipe 202 filled with heat-conducting medium. Then, the heat dissipation surface area is expanded through the outer heat dissipation fins 201, and rapid heat dissipation is achieved by utilizing air flow, ensuring that efficient heat exchange can still be maintained in a sealed environment. The waterproof structure 3 forms the first barrier to block rainwater through the roof 301, and the inclined water baffle 303 further blocks the intrusion of external rainwater. Drainage holes 302 are provided between the protective plate 304 and the water baffle 303, which can quickly drain accumulated water and block the water vapor penetration path, forming a multi-layer waterproof protection. The heat dissipation structure 2 and the waterproof structure 3 achieve functional synergy through the integrated installation of the heat conduction plate 203 and the roof 301, which not only ensures that heat is conducted from the inside to the outside, but also prevents rainwater from seeping into key components.

[0043] The combination of the two structures not only improves the transformer's waterproof performance in humid environments, but also avoids the decrease in heat dissipation efficiency caused by the closed design by optimizing the heat dissipation path, thereby significantly improving the stability and service life of the equipment, and making it suitable for the needs of power facilities in outdoor or high humidity scenarios.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
