Description

Technical Field

[0001] The present application relates to the technical field of transformers, and more specifically, to a transformer trunking structure and a transformer thereof. Background Art

[0002] A transformer is an electrical device that operates on the principle of electromagnetic induction. Its primary function is to change the magnitude of AC voltage while maintaining a constant frequency. A transformer consists of two or more winding coils and an iron core, achieving energy transmission and voltage regulation through electromagnetic induction. The transformer's wire slot structure is a key component that supports and secures the windings. Its design directly affects the winding's alignment accuracy, heat dissipation efficiency, and ease of maintenance.

[0003] After searching, the existing application number CN202310900919.5 discloses a transformer trunking structure and a transformer; it solves the problem that "the existing transformers do not have dust-proof fixed trunking, transformer core lifting and lowering, and a structure to prevent the transformer top cover from being over-pressured and flying off during use, so that after being connected to the cable, the existing transformers are mostly exposed to the outside for a long time and are not well fixed. After long-term use, dust is very likely to accumulate at the joints, affecting the contact effect, and the exposed joints and cables are very likely to collide with animals or thrown foreign objects, causing damage, which is inconvenient to use. Moreover, when inspecting the inner core of the existing transformer, the inner core needs to be removed for inspection with the help of external equipment. At the same time, when the transformer is damaged and the internal pressure is abnormal, it is very likely that the top cover will be lifted off due to excessive pressure, causing secondary damage, which is inconvenient to use."

[0004] During the application process, the inventors discovered that the above technology has the following problems: the above application document "has the advantages of dust-proof fixed wire troughs, transformer core lifting and lowering, and preventing the transformer top cover from being over-pressured and flying off. It solves the problems that dust easily accumulates at the joints after long-term use without good fixation, affecting the contact effect, the inner core needs to be removed for inspection with the help of external equipment, and the transformer is easily over-pressured and the top cover is easily over-pressured and flying off, causing secondary damage when the internal pressure is abnormal and damaged."

The structure is compact but may lack flexibility, which leads to the inability of the traditional wire trough to be flexibly adjusted. In addition, the coil insulation in the prior art is insufficient.

[0030] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0031] As attached Figures 1 to 8 A transformer wire slot structure and its transformer shown in the figure include a transformer main body 1, a monitoring structure 24 and a transformer skeleton body 30. An oil tank 2 is provided on the side of the transformer main body 1. The oil tank 2 is the main part of the transformer, which is used to accommodate the iron core and coil of the transformer and provide oil for them, and store the remaining oil for replacement. A support bracket 4 is provided on the side of the transformer main body 1 away from the oil tank 2. An oil pillow 3 is connected to the top of the support bracket 4 by bolts. A heat dissipation component 12 is installed on the left side of the transformer main body 1. The monitoring structure 24 is provided above the transformer main body 1. A respirator 13 is provided above the oil tank 2. The inner cavity of the transformer main body 1 is provided with a transformer skeleton body 30. The transformer skeleton body 30 includes a base 301 and a winding bobbin 302. The winding bobbin 302 is installed above the base 301, and a top seat 303 is provided above the winding bobbin 302. The side end face of the winding bobbin 302 is provided with several groups of wire slots 304, several A stepped insulating partition 305 is embedded between the groups of wire slots 304. The height of the partition increases with the number of winding layers, forming a gradient electric field distribution and reducing the voltage difference between layers. The inner walls of several groups of wire slots 304 are covered with a wear-resistant insulating coating 306. The wear-resistant insulating coating 306 is made of polyimide material. An adjustment component 307 is provided between the base 301 and the top seat 303. The adjustment component 307 longitudinally passes through the center of the winding drum 302. The transformer skeleton body 30 is modularly designed, and the length of the wire slots 304 is modular. The length of the wire slots 304 is dynamically adjusted to support the fixation of wire harnesses of different numbers and lengths, reduce the space occupied by redundant wire slots 304, and improve the winding density. The stepped insulating partition 305 is used to reduce the electric field strength along the height, reducing the risk of partial discharge. The wear-resistant insulating coating 306 reduces the damage of the copper wire insulation layer and increases the withstand voltage. The adjustment component 307 adjusts the length of the wire slots 304, thereby facilitating the improvement of the winding density.

[0032] The adjusting component 307 includes a first engaging post 3071 and a second engaging post 3072, and the second engaging post 3072 is placed below the first engaging post 3071. The first engaging post 3071 and the second engaging post 3072 are staggered and aligned with each other. A first engaging tooth 3073 is provided on the side of the first engaging post 3071 close to the second engaging post 3072, and a second engaging tooth 3074 is placed at the center of the two groups of first engaging teeth 3073. The first engaging teeth 3073 and the second engaging teeth 3074 are engaged with each other. When the adjusting component 307 is placed inside the winding drum 302 and the length of the winding drum 302 is adjusted, the top seat 303 is rotated so that the connecting ring 3075 inside the top seat 303 drives the first engaging post 3071 to rotate, so that the first engaging post 3071 and the second engaging post 3072 are separated, and the first engaging post 3071 and the second engaging post 3072 are moved. The first engaging post 3071 is connected to the second engaging post 3072 after the movement is completed. After the adjustment assembly 307 is fixed, the length of the winding drum 302 and the length of the adjustment assembly 307 are aligned with each other. The adjustment assembly 307 also includes a connecting ring 3075 and a clamping ring 3076. The first engaging post 3071 is connected to the clamping ring 3076 on the side away from the connecting ring 3075, and the outer surface of the clamping ring 3076 is installed with a locking piece 3077. The clamping ring 3076 and the connecting ring 3075 are both installed with a docking post 3078 on the side away from the first engaging post 3071. The connecting ring 3075, the clamping ring 3076, the locking piece 3077 and the docking post 3078 facilitate the fixation of the winding drum 302 and the fixation of the adjusted state of the winding drum 302.

[0033] The respirator 13 includes a connecting pipe 1301 and a housing 1302. The housing 1302 is connected to the bottom of the connecting pipe 1301. The outer surface of the housing 1302 is provided with an oil seal 1303. The inner wall of the housing 1302 is provided with drying particles 1304. The respirator 13 is used to detect the moisture content in the oil inside the transformer. When moisture accumulates in the oil inside the transformer body 1, the moisture will cause the insulation performance of the transformer body 1 to deteriorate, affecting the normal operation of the transformer body 1. When the temperature inside the transformer body 1 changes, the moisture in the oil will be adsorbed by the drying particles 1304, reducing the moisture content and protecting the normal use of the oil.

[0034] The monitoring structure 24 includes an oil level gauge 5 and a gas relay 6. The oil level gauge 5 and the oil pillow 3 are connected by a bolted structure with detachable bolts. The oil level is monitored by the oil level gauge 5 in the oil pillow 3 to ensure that the oil tank 2 is full of oil. At the same time, the oil pillow 3 can also play the role of replenishing oil. When the amount of oil inside the transformer body 1 decreases or the oil temperature rises, the excess oil will flow into the oil pillow 3 to maintain the oil level in the oil tank 2. In addition, the oil pillow 3 can also reduce the aging of the oil by circulating the oil. When the oil level in the oil pillow 3 is lower than the oil level gauge 5, the oil pillow 3 will Automatically replenish oil into the oil tank 2, and mix the oil in the oil pillow 3 with the oil in the oil tank 2, thereby slowing down the aging of the transformer oil. A first oil inlet pipe 25 is provided below the oil pillow 3, and the end of the first oil inlet pipe 25 is connected to a gas relay 6. A second oil inlet pipe 26 is provided on the side of the oil tank 2 close to the transformer body 1. A gas relay 11 is installed at the center of the second oil inlet pipe 26. An oil flow relay 18 is provided at the center of the heat dissipation component 12 and the respirator 13. The oil flow relay 18 is used to monitor the oil inside the transformer body 1. The oil flow relay 18 monitors the flow rate and speed of the oil flow to determine whether the oil is flowing normally. When a problem occurs, an alarm is issued to maintain the normal operation of the equipment. The oil flow relay 18 has the same working principle as the gas relay 6, but uses oil flow instead of gas to monitor the operating status of the equipment. A regulating box 16 is provided on the side of the oil tank 2 away from the transformer body 1. A monitoring box 27 is provided above the regulating box 16, so that the status of the oil-immersed transformer can be quickly monitored. A temperature sensor 28 is installed above the gas relay 6 and the gas relay 11, and a pressure sensor 29 is installed above the oil flow relay 18. The above sensors are used to monitor internal faults of the transformer and issue an alarm in time. When a fault occurs inside the transformer, the fault will affect the oil and cause the oil to decompose and produce gas. When the gas relay 6 and the gas relay 11 detect gas in the connected pipeline, they are used to issue a warning to complete the warning to the transformer.

[0035] An insulator 8 is arranged above the transformer main body 1, and an insulating sleeve 9 is provided on the outer surface of the insulator 8. A lifting ring 7 is provided on both sides of the insulator 8. The heat dissipation component 12 includes a stepper motor 21 and a fan 22. The fan 22 is installed at the output end of the stepper motor 21, and a placement bracket 23 is fixed to the bottom of the stepper motor 21 by bolts. The heat dissipation component 12 cools the oil inside the pipeline by air cooling, so that the cooled oil re-enters the transformer main body 1 for cooling. A body 19 is placed on the inner wall of the transformer main body 1, and a docking bracket 20 is connected above the body 19. A pressure relief valve 10 is provided on the side of the lifting ring 7 away from the insulator 8 for installation in the pipeline connected to the transformer, for monitoring internal faults of the transformer main body 1 and releasing pressure in time to prevent the transformer oil tank 2 from rupturing and exploding. However, when a fault occurs inside the transformer main body 1, the oil inside the transformer main body 1 will decompose to produce gas. The outlet at the tail of the valve is opened to discharge the generated gas out of the transformer. The device reduces the pressure of the transformer and protects the transformer main body 1. A tap changer 17 is installed above the inner wall of the regulating box 16. When the pressure inside the transformer main body 1 needs to be adjusted, the pressure inside the transformer main body 1 is changed by adjusting the tap changer 17. A fixing seat 14 is provided below the transformer main body 1, and a fixing bracket 15 is provided below the fixing seat 14. The fixing seat 14 and the fixing bracket 15 are used to place and install the transformer main body 1. In this embodiment, the oil level gauge 5, the gas relay 6, the pressure relief valve 10, the gas relay 11, the tap changer 17, the oil flow relay 18, the stepping motor 21, the fan 22, the temperature sensor 28 and the pressure sensor 29 are all well-known equipment purchased directly from the market by those skilled in the art. They can be customized or selected according to actual needs. Here we only use them and do not improve their structure and function. We will not go into details here.

[0036] The working process of the present application is as follows: the top seat 303 installed above the winding drum 302 and the base 301 below are of the same size, wherein an adjustment component 307 is installed inside the winding drum 302, wherein the second engaging column 3072 of the adjusting component 307 is connected to the clamping ring 3076, and the clamping ring 3076 is installed on the base 301 in conjunction with the winding drum 302 for fixing. At the same time, when the winding drum 302 is wound, when the default length of the winding drum 302 cannot be greater than the width of the number of coils of the winding, when it is necessary to extend the length of the winding drum 302, the inner surface of the top seat 303 is rotated, and the top seat 303 is rotated so that the connecting ring 3075 inside the top seat 303 drives the first engaging column 3071 The first engaging teeth 3073 of the first engaging post 3071 are rotated to separate from the second engaging teeth 3074 of the second engaging post 3072. The engaging post is moved to determine the length position of the first engaging post 3071. The first engaging teeth 3073 of the first engaging post 3071 are rotated and then the first engaging teeth 3073 are reengaged inside the second engaging teeth 3074. The first engaging teeth 3073 and the second engaging teeth 3074 are closed again to complete the fixation. After the first engaging post 3071 of the adjustment component 307 is fixed, the length between the winding reels 302 changes with the length of the adjustment component 307. The oil tank 2 is the main part of the transformer, which is used to accommodate the iron core and coil of the transformer and is It provides oil and stores the remaining oil for replacement. The height of the partition increases with the number of winding layers, forming a gradient electric field distribution and reducing the voltage difference between layers. The wear-resistant insulating coating 306 is made of polyimide material. The transformer skeleton body 30 is modularly designed, and the length of the wire slot 304 is modular. The length of the wire slot 304 is dynamically adjusted to support the fixation of wire harnesses of different numbers and lengths, reducing the space occupied by redundant wire slots 304 and improving the winding density. The stepped insulating partition 305 is used to reduce the electric field strength along the height, reducing the risk of partial discharge. The wear-resistant insulating coating 306 reduces the damage of the copper wire insulation layer and increases the withstand voltage. The adjusting component 307 adjusts the length of the wire slot 304, thereby facilitating the improvement of the winding density. Through the transformer body 1 and the monitoring Structure 24, when the transformer main body 1 is in operation, the oil contacts the body 19, so that when the body 19 is converted, the heat generated is absorbed by the oil, and at the same time, the stepper motor 21 inside the heat dissipation component 12 drives the fan 22 to rotate, and the oil inside the transformer main body 1 is cooled by air cooling. At the same time, the oil inside the oil pillow 3 and the oil inside the transformer main body 1 circulate. When the body 19 inside the transformer main body 1 fails, resulting in a short circuit and overload, the oil itself is acted on, causing the oil to decompose and produce gas, which flows inside the transformer. When the gas relay 6 and the gas relay 11 used to connect the oil pipeline detect the gas inside the pipeline, they are used to issue a warning.To prevent the gas from continuously accumulating inside the transformer body 1 and causing damage to the transformer body 1, when the oil circulation between the oil pillow 3, oil tank 2 and transformer body 1 stagnates or backflows, resulting in poor oil flow or blockage, the power signal inside the oil flow relay 18 is connected, and a warning is issued to monitor the oil circulation in real time. The breather 13 connected to the transformer increases the moisture content of the oil after the oil is continuously heated and cooled. The increased moisture will affect the insulation performance of the transformer body 1 and cause failures. The dry particles 1304 inside the breather 13 absorb the moisture inside the transformer body 1 through the connecting pipe 1301.
