Description

TECHNICAL FIELD

[0001] The application relates to the technical field of power equipment, in particular to a pole-mounted transformer complete equipment with compensation capacitors. BACKGROUND

[0002] The technical field of power equipment has developed rapidly in recent years. As an important component of the power system, the performance and stability of the pole-mounted transformer complete equipment play a key role in ensuring power supply. With the increasing demand for electricity, higher requirements are placed on the functionality and reliability of the pole-mounted transformer complete equipment. It is widely used in urban and rural distribution networks and can effectively convert high-voltage electricity into low-voltage electricity suitable for users, providing stable power support for various electrical equipment and playing an irreplaceable role in ensuring residential and industrial power supply.

[0003] In related technologies, in order to solve the problems of heat dissipation and capacitor installation of the pole-mounted transformer complete equipment, the following methods are usually used. One is to set simple cooling fins outside the main box to increase the cooling area by using the large surface of the cooling fins, thereby achieving a certain degree of heat dissipation. Another is to install the capacitor directly in the main box, which is in the same room as the transformer body, to simplify the equipment structure. Another is to set a common installation box on the main box, but the structure of the installation box is relatively simple and has no special cooling and communication design inside, and it is only a space for placing capacitors and other components.

[0004] In addition, the simple cooling fins have limited heat dissipation effect and cannot meet the heat dissipation needs of the equipment under high load, which can easily cause the equipment temperature to be too high, affecting its service life and performance. Directly installing the capacitor in the main box makes the internal space of the main box more crowded, which is not conducive to the maintenance and repair of components, and also cannot effectively cool the capacitor separately, reducing the service life of the capacitor. The common installation box lacks communication design with the internal space of the main box and reasonable cooling structure, and cannot fully utilize the insulating coolant for cooling, resulting in poor working environment for components in the installation box and prone to failure.

The wires on the circuit breaker 11 first pass through the sealing element 12, and the sealing element 12 is in contact with the surface of the wires. Meanwhile, epoxy resin is coated at the position where the wires pass through the sealing element 12. The wires for connecting the circuit breaker 11 and the transformer body need to be connected before the main body box 4 is filled with insulating cooling liquid.

[0043] Referring to Figure 3 , Figure 4 , Figure 5 , the mounting box 6 is provided with a heat dissipation opening 14 in the bottom surface at the capacitor cavity 10, and a support base 15 is welded and fixed on the inner wall of the mounting box 6 at the heat dissipation opening 14.

In addition, the side of the connecting plate 24 facing the main box 4 is fixedly connected with a shape memory alloy 27, wherein the shape memory alloy 27 is in abutment with the lower end surface of the support base 15 in the normal state, and the periphery of the shape memory alloy 27 is in abutment with the rubber strip 25, and the lower bottom surface of the shape memory alloy 27 is in abutment with the rubber clamping protrusion 26, so as to close the bottom surface of the support base 15. When the shape memory alloy 27 is heated, the side close to the main box 4 bends downward to expose the heat dissipation opening 14 and the support base 15 located in the heat dissipation opening 14, and restores to close the heat dissipation opening 14 and the bottom surface of the support base 15 when cooled. In addition, a plurality of heat dissipation holes 28 are formed in the shape memory alloy 27, and the heat dissipation holes 28 are arranged in a staggered manner with the through holes 16 on the support base 15, so as to avoid the entry of external dust into the capacitor cavity 10 while ensuring the heat dissipation efficiency inside the capacitor cavity 10.

[0046] Referring to Figure 2 , Figure 3 , Figure 4 The surfaces of both sides of the main box 4 are welded with three support columns 29 corresponding to the mounting box 6, the support columns 29 are hollow inside and communicate with the inside of the main box 4, and the insulating cooling liquid in the main box 4 can flow into the support columns 29, in addition, the support columns 29 are inclined upward towards the mounting box 6, so as to increase the heat dissipation area of the main box 4. The surface of the support column 29 is axially sleeved with a shock absorber 30, and the shock absorber is fixedly connected with a damping spring 31 axially sleeved on the surface of the support column 29, at the same time, the end of the damping spring 31 is fixedly connected with a sliding sleeve 32, the sliding sleeve 32 is sleeved on the surface of the support column 29, and the sliding sleeve 32 can slide along the surface of the support column 29. In addition, the surface of the support column 29 is fixedly connected with a limiting block 21, and the limiting block 21 is in abutment with the side of the sliding sleeve 32 away from the damping spring 31, so as to make the damping spring 31 in a compressed state, and reduce the vibration of the transformer body during operation through the cooperation of the sliding sleeve 32, the damping spring 31 and the shock absorber 30.

[0047] The first connecting rod 33 is hinged to one side surface of the sliding sleeve 32 away from the damping spring 31, and the end of the first connecting rod 33 is hinged to the second connecting rod 34, and the end of the second connecting rod 34 is rotationally connected to the outer surface of the shape memory alloy 27, and the connection between the second connecting rod 34 and the shape memory alloy 27 is close to the main body box 4. At the same time, the first connecting rod 33 and the second connecting rod 34 are provided with an included angle less than 180° on one side, and the surface of the first connecting rod 33 and the second connecting rod 34 on this side is fixedly connected with the connecting spring 35. In normal operation, the vibration received by the installation box 6 is transmitted to the damping spring 31 and the damper 30 through the second connecting rod 34, the first connecting rod 33 and the sliding sleeve 32, so as to reduce the vibration received by the installation box 6. When the shape memory alloy 27 is heated and the heat dissipation opening 14 is opened, the shape memory alloy 27 pushes the sliding sleeve 32 to slide close to the damper through the second connecting rod 34 and the first connecting rod 33, and in this process, the connecting spring 35 is deformed and compressed. The vibration of the transformer body during operation can be transmitted to the connecting spring 35, and the second connecting rod 34 can push the shape memory alloy 27 to swing regularly, so as to clean the accumulated dust at the heat dissipation hole 28.

[0048] The implementation principle of the embodiment of the present application is that when the equipment is running, the heat generated by the transformer body is absorbed by the insulating cooling liquid in the main body box 4. Since the side plate, the partition plate 8, the support base 15 and the support column 29 inside the installation box 6 are all hollow structures and are in communication with the inside of the main body box 4, the insulating cooling liquid circulates in these components to form an efficient heat exchange path. The heat is transferred to the outer wall of the installation box 6 and the cooling fins 7 through the cooling liquid, and is dissipated to the environment, realizing the cooperative heat dissipation of the transformer body and the capacitor body 5.

[0049] The heat generated by the capacitor body 5 during operation is directly conducted to the support base 15, and the cooling liquid in the support base 15 timely takes away the heat and quickly transfers the heat to the shape memory alloy 27 through the abutting relationship between the shape memory alloy 27 and the support base 15. When the temperature of the capacitor cavity 10 rises to the phase transition point of the shape memory alloy 27, the shape memory alloy 27 is deformed by heat, and the side close to the main body box 4 bends downward, exposing the heat dissipation opening 14, promoting the hot air in the capacitor cavity 10 to be discharged through convection, and cold air to enter from the gap, enhancing the heat dissipation effect. When the temperature decreases, the shape memory alloy 27 cools and restores, closing the heat dissipation opening 14, preventing dust, moisture and other pollutants from entering, and ensuring the cleanliness of the inside of the equipment.

[0050] At the same time, the damping system absorbs the vibration generated by the transformer operation and the external environment through the shock absorber, damping spring 31 and sliding sleeve 32. The vibration energy is transmitted to the first connecting rod 33 and the second connecting rod 34 through the sliding sleeve 32, and finally makes the shape memory alloy 27 produce slight regular vibration, thereby cleaning the dust accumulated at the heat dissipation hole 28 and keeping the heat dissipation unobstructed. The connecting spring 35 provides buffering between the first connecting rod 33 and the second connecting rod 34, and enhances the vibration transmission efficiency.

[0051] The design of the sealed box door 20 facilitates the regular maintenance of the circuit breaker 11, the capacitor body 5 and other components, and the welding fixation ensures the connection strength and sealing reliability of the installation box 6 and the partition plate 8 with the main body box 4, preventing the leakage of the cooling liquid. The overall equipment realizes passive intelligent heat dissipation, damping self-cleaning and convenient maintenance, is suitable for outdoor harsh environments, and significantly improves the equipment life and operation stability.

[0052] The embodiments of the specific embodiment are the preferred embodiments of the present application, and are not limited to the protection scope of the present application, wherein the same parts are indicated by the same reference numerals. Therefore, any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
