Description

Technical Field

[0001] The present invention relates to the technical field of transformer equipment manufacturing, and more particularly to an outdoor box-type transformer. Background Art

[0002] Outdoor box-type transformer (also known as box-type substation or prefabricated substation) is a compact complete set of power distribution equipment that combines high-voltage switchgear, distribution transformers and low-voltage distribution devices according to a certain wiring scheme. It is usually installed outdoors. In actual applications, most existing outdoor box-type transformers will have no-load losses. No-load losses are inherent losses generated when the transformer is energized but not loaded. They are mainly manifested in that when the iron core is repeatedly magnetized in an alternating magnetic field, the magnetic domains generate heat due to friction, and the alternating magnetic field induces eddy currents in the iron core, generating Joule heat. This heat cannot be utilized and is dissipated into the air, causing a certain amount of energy loss. In addition, outdoor box-type transformers are installed outdoors. When encountering humid and rainy weather, water vapor is easily introduced into the box, which can easily cause device short circuits or rust. For this reason, we propose an outdoor box-type transformer to solve the above problems. Summary of the Invention

The controller reads the sensor analog signal through the ADC interface, sets the high temperature trigger point to 40°C, the hysteresis to 5°C, and sets the high humidity trigger point to 80%RH, the hysteresis to 10%RH.

[0006] Furthermore, a heat recovery component is fixedly connected to the interior of the transformer component, and a drainage component is fixedly connected to the bottom of the heat recovery component.

[0007] Furthermore, the dust removal assembly includes two coil blocks, the facing ends of the two coil blocks are fixedly connected to three dust collecting rods, and the back ends of the two coil blocks are respectively fixedly connected to the inner walls on both sides of the box shell.

[0008] Furthermore, the side surfaces of one end of the three dust collecting rods are slidably sleeved with magnetic blocks, and connecting blocks are fixedly connected between two adjacent two of the three magnetic blocks. The side surfaces of the three magnetic blocks are fixedly sleeved with a casing, and the casing consists of an upper tube sleeve and a lower tube sleeve, and the upper tube sleeve and the lower tube sleeve are both semicircular tube-shaped, and both ends are fixedly connected with semicircular ring plates, and the openings of the upper tube sleeve and the lower tube sleeve are opposite to each other, and are fixedly sleeved on the side surfaces of the magnetic blocks by snap fasteners.

[0009] Furthermore, the baffle assembly includes a fixed tube shell, a swivel is rotatably sleeved on the inner side of the fixed tube shell, a turbine is fixedly sleeved on the inner side of the swivel, a rotating shaft is fixedly connected to the middle of the bottom of the turbine, and a rotating plate is fixedly connected to the bottom end of the rotating shaft.

[0010] Furthermore, the heat recovery component includes a thermoelectric component, which includes three heat-conducting plates, the top ends of the three heat-conducting plates are fixedly connected to the bottom of the transformer winding, the sides of the three heat-conducting plates are fixedly connected to an insulation shell, and the bottom ends of the three heat-conducting plates are fixedly connected to a thermoelectric power generation plate, and both ends of the thermoelectric power generation plate are electrically connected to wires.

[0011] Furthermore, the condensation assembly includes a sealed shell, the top of the sealed shell is fixedly connected to a thermoelectric power generation sheet, the bottom of the sealed shell is fixedly connected to a semiconductor refrigeration sheet, and two ends of the semiconductor refrigeration sheet are electrically connected to two ends of the thermoelectric power generation sheet; The semiconductor refrigeration plate and the temperature difference power generation plate are electrically connected to a humidity sensor, the inner side of the top of the sealed shell is fixedly connected to a fin, the inner side of the bottom of the sealed shell is fixedly connected to a guide plate, the bottom end of the back side of the sealed shell is fixedly connected to a rectangular pipe, and the bottom of the rectangular pipe is fixedly connected to a drain pipe.

[0012] Furthermore, the air collecting assembly includes an air intake channel, the back of which is fixedly connected to the front of the sealed shell, and the top of the air intake channel is provided with three circular holes, each of which is provided with a rotating fan; The rotary fan consists of fan blades and a rotating rod. The bottom of the fan blades is fixedly connected to the rotating rod. The bottom ends of the three rotating rods are rotatably connected to the inner wall of the bottom of the intake channel.

[0014] Technical effects and advantages of the present invention: The temperature and humidity inside the transformer box are detected by temperature sensors and humidity sensors. When the temperature and humidity inside the transformer box reach the set values, the controller connects the circuits of the thermoelectric generator and the semiconductor cooling plate, as well as the circuits of the motor and the solar panel. The heat of the iron core is transferred to the top heating end of the thermoelectric generator through the heat conductive plate, so that a temperature difference is formed between the top and the bottom, thereby generating current, which is then transmitted to the semiconductor cooling plate. The solar panel transmits the current to the motor, and the motor drives the fan to suck the air in the transformer box into the sealed shell. The semiconductor cooling plate creates a low-temperature environment inside the sealed shell, and the hot air and the cold liquid are transformed into water droplets. The water droplets are guided into the drain pipe through the guide plate, and then discharged by the main pipe and the branch pipe. In this way, the heat energy lost in the no-load state of the iron core is used to condense the water vapor in the air into water droplets and discharge them out of the transformer box, thereby preventing the water vapor from causing short circuit or rust of the device.

[0015] The current generated by the thermoelectric power generation sheet is used to energize the dust collecting rod, causing it to generate electrostatic adsorption, which adsorbs the dust in the transformer box onto the dust collecting rod. By applying currents in different directions to the coil blocks at both ends, magnetic field forces in different directions are formed at both ends of the dust collecting rod. The magnetic field forces at both ends of the dust collecting rod attract the magnetic block, while the other repel the magnetic block, causing the magnetic block to drive the housing to move on the dust collecting rod, scraping the dust off the surface of the dust collecting rod and collecting it in the housing.

[0018] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The outdoor box-type transformer involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] Reference Figure 1 and Figure 2 The present invention provides an outdoor box-type transformer, including a transformer assembly 1, wherein a heat recovery assembly 2 is fixedly connected to the interior of the transformer assembly 1, and a drainage assembly 3 is fixedly connected to the bottom of the heat recovery assembly 2.

[0020] What needs to be specifically explained in this embodiment is that the heat recovery component 2 and the drainage component 3 use the heat energy in the no-load loss of the transformer to condense the water vapor in the air into water droplets and discharge them out of the transformer box, so as to prevent the water vapor from causing short circuit or rust of the device. The specific structure and working principle of the above components will be described in detail later.

[0021] Reference Figure 3The transformer assembly 1 includes a box shell 101, one end of the front end of the box shell 101 is rotatably connected to the box door, the inner side of the top of the box shell 101 is fixedly connected to the transformer winding 102, the inner side of the middle part of the box shell 101 is fixedly connected to the dust removal assembly 103, and the bottom of the box shell 101 is fixedly connected to four partition assemblies 104.

[0022] It should be specifically explained in this embodiment that the transformer winding 102 mainly provides the function of the transformer box, and the number of the barrier components 104 is not limited to four and can be selected according to actual conditions.

[0023] Reference Figure 4 A controller 105 is fixedly connected to the interior of one side of the box shell 101, a humidity sensor 106 is electrically connected to one side of the controller 105, and a temperature sensor 107 is electrically connected to the front of the controller 105; The temperature sensor 107 monitors the internal temperature of the box shell 101 in real time. When the temperature exceeds the set threshold of 40°C, the controller 105 outputs a signal to start the circuit controlled by the humidity sensor 106 to reduce the temperature of the device. The humidity sensor 106 detects the humidity inside the box shell 101. When the humidity exceeds the threshold of 80%RH, the controller 105 starts the temperature sensor 107 control circuit; What needs to be specifically explained in this embodiment is that a solar photovoltaic panel is fixedly installed on the top of the box shell 101 and is connected to a solar cell. The solar photovoltaic panel and the solar cell are both existing conventional technologies and are therefore not shown in the figure. The temperature sensor 107 uses an NTC thermistor, such as an MF52 or DS18B20 digital sensor, which is suitable for -50℃-125℃; the humidity sensor 106 uses an HDC1080 or DHT22 temperature and humidity composite sensor with an accuracy of humidity ±2%RH and temperature ±0.5℃; the controller 105 uses an ArduinoNano or STM32F103, reads the sensor analog signal through the ADC interface, sets the high temperature trigger point to 40℃, the hysteresis to 5℃, and stops when it is below 35℃ to avoid frequent start and stop; sets the high humidity trigger point to 80%RH, the hysteresis to 10%RH, and stops when it is below 70%RH.

[0024] Reference Figure 5 The dust removal component 103 includes two coil blocks 1031, and the facing ends of the two coil blocks 1031 are fixedly connected to three dust collecting rods 1032, and the back ends of the two coil blocks 1031 are respectively fixedly connected to the inner walls on both sides of the box shell 101.

[0025] It should be specifically explained in this embodiment that the coil block 1031 is provided with an energized spiral coil and is connected to the solar panel. The circuit connection is controlled by the controller 105. The circuit connection method between the coil block 1031 and the solar panel is a conventional technical means and is not shown in the figure.

[0026] Reference Figure 5 and Figure 6 , the side surfaces of one end of the three dust collecting bars 1032 are all slidably sleeved with magnetic blocks 1033, and connecting blocks are fixedly connected between two adjacent two of the three magnetic blocks 1033. The sides of the three magnetic blocks 1033 are all fixedly sleeved with sleeves 1034, and the sleeves 1034 are composed of an upper sleeve and a lower sleeve. The upper sleeve and the lower sleeve are both semicircular, and both ends are fixedly connected with semicircular ring plates. The openings of the upper sleeve and the lower sleeve are opposite, and are fixedly sleeved on the sides of the magnetic blocks 1033 by buckles. When the upper and lower tube sleeves are fixedly connected to the side of the magnetic block 1033, a circular tube is formed with an annular plate fixed at both ends. The function of the annular plate is to prevent dust from leaking out. The upper and lower tube sleeves are connected by a buckle, which makes it easy to separate the upper and lower tube sleeves and clean the accumulated dust. The current generated by the heat recovery component 2 is used to energize the dust collecting rod 1032, causing it to generate electrostatic adsorption, and adsorbing the dust in the box shell 101 onto the dust collecting rod 1032. When the temperature sensor 107 reaches the threshold value of 40°C, the controller 105 controls the circuit to be turned on, and applies currents in different directions to the coil blocks 1031 at both ends, thereby forming magnetic fields in different directions at both ends of the dust collecting rod 1032. The magnetic fields at both ends of the dust collecting rod 1032 attract the magnetic block 1033, and repel the magnetic block 1033, thereby causing the magnetic block 1033 to drive the casing 1034 to move on the dust collecting rod 1032, scraping the dust off the surface of the dust collecting rod 1032 and collecting it in the casing. What needs to be specifically explained in this embodiment is that an H-bridge circuit can be used in the coil block 1031 to control the direction of the current, and the magnetic block 1033 preferably uses a permanent magnet with high coercive force such as neodymium iron boron. The gap between the magnetic block 1033 and the dust collecting rod 1032 is recommended to be ≤0.1mm, and a PTFE wear-resistant coating is used to reduce the friction coefficient (μ < 0.1). The heat recovery component 2 makes the electrostatic voltage generated by the dust collecting rod 1032 15-20V, and the PM2.5 particle capture rate is >92% at a wind speed of 1.5m / s, which has a good dust removal effect.

[0027] Reference Figure 7 The baffle assembly 104 includes a fixed tube shell 1041, a rotating ring 1042 is rotatably sleeved on the inner side of the fixed tube shell 1041, a turbine 1043 is fixedly sleeved on the inner side of the rotating ring 1042, a rotating shaft 1044 is fixedly connected to the middle of the bottom of the turbine 1043, and a rotating plate 1045 is fixedly connected to the bottom end of the rotating shaft 1044.

[0028] What needs to be specifically explained in this embodiment is that the fixed tube shell 1041 and the rotating ring 1042 are rotationally connected through bearings. When the turbine 1043 is blown by the airflow discharged by the drainage component 3, the turbine 1043 drives the rotating plate 1045 to rotate, driving away the small animals at the bottom of the transformer box to prevent them from invading the transformer box.

[0029] Reference Figure 8 The heat recovery component 2 includes a thermoelectric component 201, which is fixedly connected to the bottom of the transformer winding 102. The bottom of the thermoelectric component 201 is fixedly connected to a condensation component 202, and the front of the condensation component 202 is fixedly connected to a gas collection component 203.

[0030] Reference Figure 9 The thermoelectric component 201 includes three heat-conducting plates 2011, the top ends of the three heat-conducting plates 2011 are fixedly connected to the bottom of the transformer winding 102, the sides of the three heat-conducting plates 2011 are fixedly connected to an insulation shell, and the bottom ends of the three heat-conducting plates 2011 are fixedly connected to a thermoelectric power generation plate 2012, and both ends of the thermoelectric power generation plate 2012 are electrically connected to wires.

[0031] It should be specifically noted that in this embodiment, the number of the heat conducting sheets 2011 is three, but is not limited to three. The number can be set according to actual conditions. The heat conducting sheets 2011 transfer the heat of the transformer winding 102 to the thermoelectric power generation sheet 2012, so that a temperature difference is formed between the top and bottom of the thermoelectric power generation sheet 2012, thereby generating current. The heat conducting sheet 2011 is made of a high thermal conductivity material, preferably copper, with a thermal conductivity of 401 W / m·K. The thermoelectric generator 2012 uses TEC1-12706 (12V / 6A, generating approximately 5W of power at a temperature difference of 30°C). The temperature of the outdoor box-type transformer under load can reach 80°C-120°C, the temperature difference of the thermoelectric generator can reach 40°C-80°C, and the power generation capacity can reach 6-11W. Reference Figure 10 The condensation component 202 includes a sealed shell 2021, the top of the sealed shell 2021 is fixedly connected to a thermoelectric power generation sheet 2012, the bottom of the sealed shell 2021 is fixedly connected to a semiconductor refrigeration sheet 2024, both ends of the semiconductor refrigeration sheet 2024 are electrically connected to both ends of the thermoelectric power generation sheet 2012, and one end of the semiconductor refrigeration sheet 2024 and the thermoelectric power generation sheet 2012 is electrically connected to a humidity sensor 106, the inner side of the top of the sealed shell 2021 is fixedly connected to a fin 2022, and the inner side of the bottom of the sealed shell 2021 is fixedly connected to a guide plate 2023.

[0032] What needs to be specifically explained in this embodiment is that the thermoelectric power generation sheet 2012 is electrically connected to the dust collecting rod 1032, and the circuit connection is a conventional connection relationship, so it is not reflected in the figure. The thermoelectric power generation sheet 2012 and the semiconductor refrigeration sheet 2024 are both existing technologies, so the principle is not explained in detail. The front of the guide plate 2023 is higher than the back to form an inclination angle of 30°. The current generated by the thermoelectric power generation sheet 2012 is transmitted to the semiconductor refrigeration sheet 2024, thereby cooling the top of the semiconductor refrigeration sheet 2024 and forming a low-temperature environment in the sealed shell 2021. 20121 is connected to the thermoelectric power generation sheet 2012, thereby reducing the temperature of the bottom of the thermoelectric power generation sheet 2012, thereby increasing the temperature difference between the top and bottom of the thermoelectric power generation sheet 2012, increasing the current generated by the thermoelectric power generation sheet 2012, and further improving the cooling effect of the semiconductor refrigeration sheet 2024.

[0033] Reference Figure 11 The bottom end of the back side of the sealing shell 2021 is fixedly connected to a rectangular pipe, and the bottom of the rectangular pipe is fixedly connected to a drain pipe 2025.

[0034] What needs to be specifically explained in this embodiment is that the temperature in the sealed shell 2021 is lower than the external temperature. When the air enters the sealed shell 2021, the water vapor in the air condenses into water droplets and gathers on the surface 2022. When more and more water droplets are condensed, the water droplets will drip from 2022 and flow along the guide plate 2023 to the drain pipe 2025.

[0035] Reference Figure 12 , the gas collecting component 203 includes an air intake channel 2031, the back of the air intake channel 2031 is fixedly connected to the front of the sealing shell 2021, the top of the air intake channel 2031 is provided with three circular holes, and a rotating fan 2032 is installed in each of the three circular holes. The rotating fan 2032 is composed of fan blades and a rotating rod. The bottom of the fan blade is fixedly connected to the rotating rod, and the bottom ends of the three rotating rods are rotatably connected to the inner wall of the bottom of the air intake channel 2031. The sides of the three rotating rods are movably sleeved with a transmission belt 2033. The bottom of the air intake channel 2031 is fixedly connected to a motor, and the driving end of the motor is fixedly connected to the bottom end of a rotating rod. The motor is electrically connected to the temperature sensor 107; When the temperature inside the transformer box reaches 40°C, the temperature sensor 107 connects the circuit of the motor, allowing the motor to operate. The motor drives the rotating fan 2032 to draw the air inside the transformer box into the sealed shell 2021, thereby cooling the inside of the transformer box. In this embodiment, it is necessary to specifically explain that: Figure 12The driving end of the middle motor is fixedly connected to the bottom end of the middle one of the three rotating rods. In actual implementation, any of the three rotating rods can be used. The motor is electrically connected to the solar cell, and the controller 105 controls its circuit. When the temperature sensor 107 reaches the threshold, the circuit is connected, and when the temperature sensor 107 does not reach the threshold, the circuit is disconnected.

[0036] The humidity sensor 106 and the temperature sensor 107 are used to detect the temperature and humidity inside the transformer box. When the temperature inside the transformer box reaches 40°C and the humidity reaches 80%RH, the controller 105 connects the thermoelectric generator 2012 and the semiconductor cooling sheet 2024 as well as the circuit of the motor and the solar panel. The heat conducting sheet 2011 transfers the heat of the transformer winding 102 to the thermoelectric generator 2012, so that a temperature difference is formed between the top and bottom of the thermoelectric generator 2012, thereby generating current, which is then transmitted to the semiconductor cooling sheet 2024. 024, the solar panel transmits electrical energy to the motor, which drives the rotating fan 2032 to draw air from the transformer box into the sealed shell 2021. The semiconductor cooling plate 2024 creates a low-temperature environment inside the sealed shell 2021. The hot air and the cold liquid are transformed into water droplets, which are guided into the drain pipe 2025 by the guide plate 2023. The water droplets are then discharged through the main pipe 301 and the branch pipe 302. In this way, the heat energy lost in the no-load condition of the iron core is used to condense the water vapor in the air into water droplets and discharge them out of the transformer box, thus preventing the water vapor from causing short circuits or corrosion of components. When the humidity sensor 106 detects that the humidity is ≥80%RH or the temperature sensor 107 detects that the temperature is ≥40℃, the controller 105 preferentially connects the motor circuit of the semiconductor refrigeration plate 2024 to ensure that the dehumidification and heat dissipation functions are started, and then starts the circuit of the dust removal component 103. The cooling effect of the semiconductor refrigeration plate 2024 will reduce the temperature of the sealed shell 2021, thereby increasing the temperature difference between the top and bottom of the thermoelectric power generation plate 2012, further improving the power generation efficiency, and forming a positive feedback loop. At this time, the controller 105 allocates more power to the semiconductor refrigeration plate to enhance the dehumidification capacity. The power demand of the dust removal component 103 is relatively stable (electrostatic adsorption and periodic magnetic field drive), and the remaining electrical energy is preferentially used to maintain its operation. The power priority allocation and dynamic adjustment of the controller 105 are existing technologies and are not described in detail.

[0037] Reference Figure 13 The drainage component 3 includes a main pipe 301 , the top of the main pipe 301 is fixedly connected to the drainage pipe 2025 , and the bottom of the main pipe 301 is fixedly connected to four branch pipes 302 .

[0038] What needs to be specifically explained in this embodiment is that the number of branch pipes 302 corresponds to the barrier assembly 104, and the air sucked into the sealed shell 2021 by the air collecting assembly 203 is discharged from the bottom end of the branch pipe 302, carrying out condensed water, and the discharged wind force drives the turbine 1043 to rotate, and the turbine 1043 drives the rotating plate 1045 to rotate, driving away the small animals at the bottom of the transformer box to prevent them from invading the transformer box.

[0039] The working principle of the present invention is as follows: the humidity sensor 106 and the temperature sensor 107 detect the temperature and humidity inside the transformer box. When the temperature inside the transformer box reaches 40°C and the humidity reaches 80%RH, the controller 105 connects the thermoelectric generator 2012 and the semiconductor cooling plate 2024 as well as the circuit of the motor and the solar panel. The heat conducting plate 2011 transfers the heat of the transformer winding 102 to the thermoelectric generator 2012, so that a temperature difference is formed between the top and bottom of the thermoelectric generator 2012, thereby generating current, which is then transmitted to the semiconductor cooling plate 2024. The cooling plate 2024 and the solar panel transmit electrical energy to the motor. The motor drives the rotating fan 2032 to draw air from the transformer box into the sealed shell 221. The semiconductor cooling plate 2024 creates a low-temperature environment inside the sealed shell 2021. The hot air and the cold liquid are transformed into water droplets. The water droplets are guided into the drain pipe 2025 by the guide plate 2023 and then discharged by the main pipe 301 and the branch pipe 302. In this way, the heat energy lost in the no-load state of the iron core is used to condense the water vapor in the air into water droplets and discharge them out of the transformer box, thus preventing the water vapor from causing short circuits or corrosion of components. The current generated by the thermoelectric power generation sheet 2012 is used to energize the dust collecting rod 1032, causing it to generate electrostatic adsorption, and adsorbing the dust in the box shell 101 onto the dust collecting rod 1032. The controller 105 controls the circuit to be turned on, and applies currents in different directions to the coil blocks 1031 at both ends, thereby forming magnetic field forces in different directions at both ends of the dust collecting rod 1032. The magnetic field forces at both ends of the dust collecting rod 1032 attract the magnetic block 1033, and repel the magnetic block 1033, thereby causing the magnetic block 1033 to drive the shell 1034 to move on the dust collecting rod 1032, scraping off the dust on the surface of the dust collecting rod 1032 and collecting it in the shell.
