Description

Technical Field

[0001] This utility model relates to the field of power equipment cooling and protection technology, specifically an automatic spray device for transformer coolers. Background Technology

[0002] Transformers play a crucial role in the operation of power systems, and their stable operation directly affects the reliability of power supply. However, traditional transformer cooling methods face many challenges.

[0003] In high-temperature environments, relying solely on natural air cooling or fan cooling has limited heat dissipation efficiency and is insufficient to meet the heat dissipation requirements of transformers operating under high loads. This can easily lead to equipment failure due to overheating and affect its service life.

[0004] In harsh environments with high dust levels and floating willow catkins, dust and catkins easily adhere to transformer coolers, hindering heat dissipation and weakening the cooling effect. Frequent manual cleaning is time-consuming and labor-intensive, increasing operation and maintenance costs.

[0005] In addition, traditional cooling devices have complex installation structures, are inconvenient to maintain, and their pipes are prone to corrosion and damage, making them difficult to adapt to complex and ever-changing outdoor operating environments.

[0006] In view of these problems, there is an urgent need for an auxiliary device for transformer coolers that can efficiently dissipate heat, automatically clean, be easy to install and maintain, and adapt to harsh environments. This automatic spray device for transformer coolers was developed to meet this need. Utility Model Content

[0007] In order to solve the problems of the prior art, this utility model provides an automatic spraying device for transformer coolers.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: an automatic spraying device for a transformer cooler, comprising a transformer cooler and a spraying main pipe, the transformer cooler and the spraying main pipe being fixedly connected, a dustproof net being fixedly connected to one side of the transformer cooler, a tee pipe being fixedly connected to one end of the spraying main pipe, and the other end being fixedly connected to the output end of a booster pump, a primary spraying branch pipe being fixedly connected to one end of the tee pipe, and a manual ball valve being fixedly connected to the other end, a secondary spraying branch pipe being fixedly connected to one end of the spraying head, and a spraying head being fixedly connected to one end of the secondary spraying branch pipe, the dustproof net having perforations and slots, the secondary spraying branch pipes passing through the perforations and slots, and the spraying head being located inside the dustproof net to spray the interior of the transformer cooler.

[0009] By using a spray system in conjunction with a transformer cooler, the interior of the transformer cooler is sprayed through a dustproof net.

[0010] In some specific implementations, the primary spray branch pipe is fixedly connected to the transformer cooler by a fixing clamp. The transformer cooler has an installation hole on one side, and the installation hole and the fixing clamp are fixedly connected by bolts. The fixing clamp, the installation hole, and the bolts cooperate to firmly fix the primary spray branch pipe.

[0011] In some specific implementations, a willow catkin cleaning device is fixedly connected to one side of the transformer cooler for cleaning the dustproof net; this specifically addresses the problem of willow catkins easily adhering to the dustproof net and clogging the mesh, further enhancing the cleaning effect of the dustproof net and maintaining good ventilation and heat dissipation conditions. A support frame is fixedly connected to the outside of the transformer cooler for installing and fixing the transformer cooler, providing stable support to ensure its stability in the installation position and preventing shaking or displacement from affecting the operation of the equipment.

[0012] In some specific implementations, a placement slot is provided on one side of the transformer cooler, inside which the primary spray branch pipes are placed. This organizes the layout of the primary spray branch pipes, avoids clutter, and provides some protection for the branch pipes, reducing the risk of damage from external impacts.

[0013] In some specific implementations, the input end of the booster pump is connected to a quick connector via a water pipe for quick assembly and disassembly with an external water pipe. The quick connector is set to a DN25 quick-connect interface; this improves the efficiency of equipment installation, maintenance, and water replenishment operations, saving time and manpower.

[0014] In some specific implementations, the transformer cooler is equipped with fan blades to actively promote airflow, accelerate heat dissipation, and work in conjunction with spray cooling to enhance the transformer cooling effect and improve heat dissipation efficiency.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model sprays water directly into the transformer cooler through a spray head. Utilizing the principle of water evaporation and heat absorption, it can quickly and effectively reduce the equipment temperature. Compared with traditional natural air cooling or simply relying on fan heat dissipation, it can significantly enhance the cooling effect in high-temperature environments, ensuring that the transformer can maintain a stable operating temperature even when running under high load, reducing the risk of failure caused by overheating, and extending the service life of the equipment.

[0026] like Figures 1 to 6 An automatic spraying device for a transformer cooler is shown, comprising a transformer cooler 1 and a spraying main pipe 2. The transformer cooler 1 and the spraying main pipe 2 are fixedly connected. A dustproof net 12 is fixedly connected to one side of the transformer cooler 1. A three-way pipe is fixedly connected to one end of the spraying main pipe 2, and the other end is fixedly connected to the output end of a booster pump 4. A primary spraying branch pipe 21 is fixedly connected to one end of the three-way pipe, and a manual ball valve 24 is fixedly connected to the other end. A secondary spraying branch pipe 22 is fixedly connected to one end of a spraying head 23, and a spraying head 23 is fixedly connected to one end of the secondary spraying branch pipe 22. The spraying head 23 sprays water onto the dustproof net 12. The dustproof net 12 has perforated slots, through which the secondary spraying branch pipe 22 passes. The spraying head 23 is located inside the dustproof net 12 and sprays water onto the interior of the transformer cooler 1.

[0027] All pipes are made of stainless steel. The main sprinkler pipe 2 is a DN25 pipe, and the primary sprinkler branch pipe 21 and the secondary sprinkler branch pipe 22 are DN15 pipes.

[0028] The primary spray branch pipe 21 is fixedly connected to the transformer cooler 1 via a fixing clamp 6. A mounting hole 15 is provided on one side of the transformer cooler 1, and the mounting hole 15 is fixedly connected to the fixing clamp 6 via bolts 5. A willow catkin cleaning device 3 is fixedly connected to one side of the transformer cooler 1 for cleaning the dustproof net 12.

A placement groove 14 is provided on one side of the transformer cooler 1, inside which the primary spray branch pipe 21 is placed. The input end of the booster pump 4 is connected to a quick connector 41 via a water pipe for quick connection and disconnection with an external water pipe. The quick connector is a DN25 quick-connect interface. The transformer cooler 1 is equipped with fan blades 11.

[0029] Maximum flow rate of the booster pump: 5.0 m³ / h 3 / h, maximum head: 45m, rated flow rate: 3.0m³ / h 3 / h, rated head: 34m, maximum suction head: 8m, power: 600W 4.0A, piping inner diameter: 25mm.

[0030] In summary, this utility model has the following working principle:

[0031] System startup and water source connection

[0032] A quick connection is made between the external water pipe and the DN25 quick-connect interface 41 at the input end of the booster pump 4 to ensure water supply. After the booster pump starts, the water flow is pressurized and delivered to the main sprinkler pipe 2.

[0033] Water distribution and pipeline transmission

[0034] Pressurized water flows through the main sprinkler pipe (DN25 stainless steel pipe) into the tee pipe, where it splits into two paths:

[0035] Main path: It enters the secondary branch pipe (DN15) through the primary branch pipe of the spray system (DN15) and is finally sprayed out by the spray head 23.

[0036] The water flow direction is controlled by the manual ball valve 24, which is used to drain the water inside the pipeline system and prevent water from freezing at low temperatures.

[0037] The primary branch pipe 21 of the spray system is fixed to the mounting hole 15 of the transformer cooler 1 by the fixing clamp 6 and bolt 5 to ensure the stability of the pipe; the primary branch pipe is placed in the placement groove 14 on the side of the cooler to keep the structure compact.

[0038] Spray cleaning and cooling process

[0039] Dust screen cleaning: Spray head 23 passes through the holes and grooves of dust screen 12, located inside it, and sprays water directly into the interior to cool it down.

[0040] Internal cooling: Water is sprayed into the transformer cooler at the same time, and the temperature of the equipment is reduced by the heat absorption of water evaporation, thus enhancing the cooling effect.

[0041] Assisted cleaning: The willow catkin cleaning device 3 on one side of the dustproof net works simultaneously, working in conjunction with the spray water flow to further enhance the cleaning effect.

[0042] System shutdown and drainage

[0043] After the booster pump is turned off, the water flow stops. The quick-connect interface 41 can quickly disconnect the external water source, and the manual ball valve 24 can drain the residual water in the pipeline (especially for freezing prevention in low-temperature environments).

[0044] Core design advantages

[0045] High-efficiency cleaning and cooling: The spray system acts directly on the dust screen and the interior, providing dual protection for heat dissipation efficiency.

[0046] Modular and stable: Stainless steel pipes are corrosion resistant, and fixing clamps and support frames ensure that the device is earthquake resistant and displacement resistant.

[0047] Flexible control: The flow rate can be adjusted manually with a ball valve, and the quick-connect interface facilitates rapid maintenance. The willow catkin removal device reduces the need for manual intervention.

[0048] Application scenarios

[0049] Suitable for transformer cooling systems in environments with high dust and floating willow catkins, especially during high temperatures in summer or when the equipment is under high load, automatic spraying can significantly improve heat dissipation performance and extend equipment life.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
