Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-voltage substations, more particularly to a heat dissipation adjusting device for high-voltage substations. BACKGROUND

[0002] The development of high-voltage substations is rooted in the demand for large-scale and efficient power systems. As industries expand and cities develop, the distance of power transmission increases, and the capacity surges, making low-voltage distribution difficult to meet demand, which has driven the birth of high-voltage substations. Early substations relied on simple power transformation equipment, which was inefficient and unstable. The breakthrough in electromagnetic induction technology has promoted the maturity of transformers, enabling voltage rise and fall, laying the foundation for high-voltage power transmission. At the same time, the upgrading of devices such as circuit breakers and disconnectors has solved the problem of high-voltage circuit on-off control. The integration of automation technology is a key leap. Traditional substations rely on manual operation, which has a response lag problem. With the development of computer and communication technology, remote monitoring and automatic protection systems have become popular, enabling real-time monitoring of operating conditions and rapid handling of faults, improving power supply reliability. The application of new materials also helps upgrade, with insulation materials improving equipment voltage resistance, and high-strength steel reinforcing cabinet protection to adapt to complex environments. Today, high-voltage substations have become the hub of the power system, connecting the power generation end and the user end, supporting the stable power supply of modern society.

[0003] The high-voltage substations in the prior art still have many deficiencies. Firstly, the heat dissipation performance is poor. Since high-voltage substations have many electrical components and high power, a large amount of heat is generated, which can easily cause electrical damage and major disasters if not effectively dissipated in time. Secondly, the safety protection is poor. High-voltage substations are in a state of continuous operation and work under high temperature and high pressure, so the protection of electrical components is particularly important, which can easily cause damage to electrical components and lead to the possibility of power failure or explosion. Thirdly, the high-voltage substation occupies a large area and needs to be located in an open area, which is difficult to layout in cities with limited land resources, and a safety distance needs to be set around, resulting in low land utilization and high operating costs.

The heat generated by the windings and cores during operation is transferred to the oil tank wall through oil convection and then dissipated to the surrounding environment, thereby avoiding damage to the components due to high temperature.

The iron core winding assembly comprises an iron core winding, a primary winding, an isolation layer and a gasket, which is beneficial to meet the voltage requirements of different power transmission and power consumption scenarios, energy transmission intermediates, and windings that transfer electrical energy through electromagnetic coupling. The high magnetic permeability of the iron core can concentrate magnetic flux and reduce magnetic loss, thereby improving energy transmission efficiency and minimizing energy loss during conversion. The insulation treatment of the winding can prevent inter-turn short circuit and ensure stable current flow, which is the key to safe and efficient operation of the transformer box.

[0016] 4. The present application is advantageous to release huge energy, which exists in the form of heat energy, out of the core assembly, which comprises a core and a core clamp, by means of a coolant, to provide energy source for subsequent power generation and other processes. The core clamp mainly plays a role of fixing and positioning.

[0034] Wherein, the motor 121, the chain 122, the fan 123 and the gear 124, the side of the motor 121 is fixedly connected with the side of the high-voltage substation shell 11, the side of the motor 121 is movably sleeved with the side of the gear 124, the side of the gear 124 is movably sleeved with the inner wall of the chain 122, the side of the motor 121 is movably sleeved with the side of the fan 123, the motor 121 drives the gear 124 to rotate and drives the fan 123 to rotate at the same time, the gear 124 drives the chain 122 to rotate, and at the same time the chain 122 drives the gears 124 on both sides to rotate to drive the fans 123 on both sides to rotate.

[0035] The working principle of the present application is that the core releases heat energy to the coolant in the form of heat energy, the coolant absorbs heat and then flows out of the core through the circulating system and provides an energy source for generating electric energy, and the electric energy flows through the iron core winding which is uniformly wound on the closed core made of silicon steel sheets, and the high magnetic conductivity of the iron core can converge the magnetic flux and reduce the magnetic loss. When the primary winding is connected to an alternating current, an alternating magnetic flux will be generated in the iron core, and this magnetic flux will pass through the iron core winding at the same time. The changing magnetic flux will induce an alternating electromotive force in the iron core winding, and the electromotive force is proportional to the number of turns of the winding. When the iron core winding is connected to a load, an electric current will be generated, realizing the transfer of electric energy from the primary side to the secondary side. At the same time, the current flows through the transformer to adjust the voltage size to output the current. The transformer oil stored in the top oil tank serves as the core medium. On the one hand, the high insulation performance of the oil is used to isolate the electrical connection between the winding, iron core and shell inside the device, preventing short circuit failure, and filling the gap between the windings to improve the overall insulation strength. On the other hand, the heat generated by the winding and iron core during device operation is transferred to the transformer oil through heat conduction. The hot oil flows upward due to the decrease in density, and the cold oil is supplemented from the bottom to form a natural convection circulation. The heat is finally dissipated to the outside through the oil tank wall, realizing heat dissipation and cooling. When the infrared thermometer detects that the temperature in the high-voltage substation is too high, the motor drives the gear to move, the gear drives the chain to rotate, the chain drives the two side gears to rotate, and the motor drives the fan to rotate. The fan blows the outer wall of the oil tank or the radiator through active blowing, accelerates the air flow, and enhances the heat exchange speed between the oil tank and the external environment. For the equipment that circulates hot oil to the radiator, the fan directly acts on the radiator fins to quickly remove the heat in the oil, so that the cooled oil flows back to the bottom of the oil tank faster to participate in the next cycle, significantly improving the overall heat dissipation efficiency. At the same time, the high-voltage substation shell is provided with an external ventilation opening, which forms a communication channel with the internal space of the device and the external atmosphere, and uses the natural flow of air or cooperates with the fan to realize forced convection, so as to cool the high-voltage substation.
