Description
Technical Field
[0001] This utility model relates to the field of transformer technology, and in particular to a photovoltaic and wind power dual-winding split dry-type transformer. Background Technology
[0002] Photovoltaic and wind power require adaptation to different voltage frequencies, which traditional transformers struggle to handle. Dual-winding split dry-type transformers can independently transform and isolate voltages, adapting to the grid connection needs of new energy sources.
[0003] Traditional split dry-type transformers generally consist of a casing, heat sinks, temperature monitoring devices, and slide rails. They mainly achieve voltage level adjustment through internal electromagnetic conversion, while maintaining operational stability and safety, and meeting the basic requirements for power transmission and distribution.
[0004] Traditional split dry-type transformers lack water cooling devices and rely solely on natural heat dissipation from heat sinks. Under high load operation or high ambient temperature, their heat dissipation efficiency is insufficient. Furthermore, the slide rails lack limit devices, making them prone to excessive sliding during movement and maintenance, which can lead to collisions and increase the difficulty of installation and positioning. To address these issues, a photovoltaic and wind power dual-winding split dry-type transformer is proposed. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a photovoltaic and wind power dual-winding split dry-type transformer, which aims to improve the existing technology where the lack of a water-cooling heat dissipation device and reliance on natural heat dissipation from heat sinks makes it difficult to meet the heat dissipation requirements under high load operation or high ambient temperature. At the same time, the lack of a limit device on the slide rail makes it easy to slide excessively during movement and maintenance, leading to collisions and increasing the difficulty of installation and positioning.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic wind power dual-winding split dry-type transformer, comprising a housing, a plurality of supports fixedly connected to the top of the housing, rain covers fixedly connected to the top of the plurality of supports, heat dissipation grilles fixedly connected to the outer side of the plurality of supports, a fan penetrating and fixedly connected to the top of the housing, a water-cooling pipe penetrating and connected to the inside of the housing, a water tank penetrating and connected to both ends of the water-cooling pipe, a water pump fixedly connected to both ends of the water-cooling pipe, a base fixedly connected to the bottom of the housing, and ventilation openings fixedly connected to both sides of the housing; As a further description of the above technical solution: a slot is fixedly connected to the bottom of the inner wall of the box, a placement seat is slidably connected to both sides of the slot, a pin is slidably connected inside the slot, a spring is sleeved on the outside of both pins, a limit block is fixedly connected to the outside of both pins, and a pin seat is fixedly connected to the inside of the slot. As a further description of the above technical solution: multiple hinges are fixedly connected to the outside of the box, a box door is fixedly connected to the outside of the hinges, and a handle is fixedly connected to the outside of the box door; As a further description of the above technical solution: the water tank is fixedly connected to the top of the base; As a further description of the above technical solution: the water pump is fixedly connected inside the water tank; As a further description of the above technical solution: both of the aforementioned pins are slidably connected inside the pin socket; As a further description of the above technical solution: both limiting blocks are slidably connected inside the pin seat; As a further description of the above technical solution: both springs are fixedly connected between the limiting block and the pin seat.
[0007] This utility model has the following beneficial effects: 1. In this invention, a water pump drives the coolant in the water tank to circulate in the water-cooling pipes. The coolant flows through the heat-generating parts of the transformer, absorbs heat, and then flows back to the water tank. It then exchanges heat with the air inside the tank through the water-cooling pipes, assisting air cooling to enhance heat dissipation and ensure stable transformer operation. The rain cover prevents rainwater from entering the tank, while the support frame creates a ventilation space, allowing smooth airflow through the heat dissipation grilles, thus protecting against rain without affecting heat dissipation.
[0008] 2. In this utility model, the placement seat is used to install the core components of the transformer. During installation, the placement seat slides into the slot, and the pin rod is inserted into the pin seat by the spring force. The limiting block restricts the displacement of the pin rod, so as to achieve quick and stable fixing, facilitate installation and subsequent maintenance and disassembly, ensure the stability of the internal components of the transformer, and ensure the reliable operation of the equipment.

[0011] 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.
[0012] Reference Figure 1 and Figure 2 An embodiment of this utility model provides a photovoltaic wind power dual-winding split dry-type transformer, including a housing 1, a plurality of brackets 8 fixedly connected to the top of the housing 1, a rain cover 7 fixedly connected to the top of the plurality of brackets 8, a heat dissipation grille 6 fixedly connected to the outside of the plurality of brackets 8, a fan 9 passing through and fixedly connected to the top of the housing 1, a water cooling pipe 10 passing through and connected to the inside of the housing 1, a water tank 11 passing through and connected to both ends of the water cooling pipe 10, a water pump 12 fixedly connected to both ends of the water cooling pipe 10, a base 3 fixedly connected to the bottom of the housing 1, ventilation openings 13 fixedly connected to both sides of the housing 1, a plurality of hinges 2 fixedly connected to the outside of the housing 1, a door 4 fixedly connected to the outside of the hinges 2, a handle 5 fixedly connected to the outside of the door 4, a water tank 11 fixedly connected to the top of the base 3, a water pump 12 fixedly connected to the inside of the water tank 11, and two limiting blocks 19 slidably connected to the inside of the pin seat 16.
[0013] The top is supported by a bracket 8, which provides a rain cover 7, creating a protective and ventilated space. Combined with an external heat dissipation grille 6, it creates a channel for heat dissipation. An internal fan 9 accelerates air convection inside and outside the enclosure 1. Simultaneously, water cooling pipes 10, a water tank 11, and a water pump 12 are activated for water cooling circulation. The coolant flows through the heat-generating components, absorbs heat, and then flows back, exchanging heat with the air via the water cooling pipes 10. This combined air and water cooling efficiently dissipates operating heat, meeting the heat dissipation requirements of photovoltaic and wind power scenarios. The outer hinge 2 of the enclosure 1 connects to the door 4, which can be easily opened and closed via a handle 5, enabling inspection and protection of internal components. The bottom base 3 supports the water tank 11, ensuring a stable layout of the water cooling system. Combined with the pin seat 16 and limit block 19 structure, the transformer balances heat dissipation efficiency and maintenance convenience during photovoltaic and wind power conversion and transmission, maintaining stable operation.
[0014] Reference Figure 1 and Figure 3The bottom of the inner wall of the box 1 is fixedly connected to a slot 15. The slot 15 is slidably connected to a placement seat 14 on both sides. The slot 15 is slidably connected to a pin 17. The two pins 17 are fitted with springs 18 on the outside. The two pins 17 are fixedly connected to a limit block 19. The slot 15 is fixedly connected to a pin seat 16 on the inside. The two pins 17 are slidably connected inside the pin seat 16. The two springs 18 are fixedly connected between the limit block 19 and the pin seat 16.
[0015] The slot 15 at the bottom of the inner wall of the housing 1 is the supporting foundation for the core components of the transformer. The sliding mounting seats 14 on both sides are used to support key components. During installation, they can be precisely slid into the slot 15 for initial positioning. The pin 17 inside the slot 15 is fitted with a spring 18 and is also connected to a limiting block 19. It cooperates with the inner pin seat 16. The spring 18 pushes the pin 17 into the pin seat 16, and the limiting block 19 is locked in the pin seat 16, firmly locking the mounting seat 14 in the slot 15. This ensures the stability of the core components during installation. For later maintenance, the mounting seat 14 can be easily removed by pulling the pin 17 to compress the spring 18 and disengage it from the pin seat 16. This convenient disassembly and assembly ensures the stability of the equipment during operation.
[0016] Working Principle: Fan 9 operates, accelerating airflow inside and outside the enclosure 1. Heat is exchanged with the outside air through vents 13, and in conjunction with the top heat dissipation grille 6, heat is quickly expelled from the enclosure, reducing the transformer's operating temperature. Water pump 12 drives the coolant in water tank 11, circulating it through water-cooling pipes 10. The coolant flows through the transformer's heat-generating parts, absorbs heat, and then returns to the water tank, exchanging heat with the air inside the enclosure through the water-cooling pipes, assisting air cooling to enhance heat dissipation and ensuring stable transformer operation. Rain cover 7 prevents rainwater from entering the enclosure, while bracket 8 provides support and creates ventilation space, allowing smooth airflow through the heat dissipation grille 6, providing rain protection without affecting heat dissipation. Mounting base 14 is used to install the transformer's core components. During installation, mounting base 14 slides into slot 15, and pin rod 17 is inserted into pin seat 16 by spring force 18. Limiting block 19 restricts the pin rod's displacement, achieving quick and stable fixing, facilitating installation and subsequent maintenance disassembly, ensuring the stability of the transformer's internal components, and ensuring reliable equipment operation.
[0017] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
