Description

Technical Field

[0001] This invention relates to the field of power transmission technology, and more specifically to a high-power insulated power transmission device. Background Technology

[0002] High-power insulated power transmission devices consist of two insulated enclosures, one for transmitting electrical energy and the other for receiving it. There can be a certain gap between the two devices, which can be air, water, an insulating material, or a specific conductive metal. Insulated power transmission uses electromagnetic coupling to transmit power, that is, the electrical energy input at the transmitting end is converted into magnetic energy and conducted through a medium, and the receiving end converts the magnetic energy back into electrical energy for output. Its main application is in cable transmission connections.

[0003] In high-power insulated power transmission equipment, packaging films made of polyolefin materials such as polyethylene and polypropylene are often used as outer insulation. Polyolefin materials have poor temperature resistance. During high-power power transmission operations, the coils and inner cores generate a large amount of heat. If this heat cannot be dissipated in time, it will soften or even burn the insulating packaging film, leading to partial discharge and causing equipment failure. In high-power processes, the electric field on the surface of the high-voltage conductor in the insulated power transmission equipment is too strong, which will cause a corona effect and result in energy loss. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-power insulated power transmission device, comprising a power transmission frame, the power transmission frame comprising an inner core, wherein an electrocouple coil is fixedly sleeved on both sides of the inner core, mounting plates are fixedly connected to both sides of the front of the upper and lower ends of the inner core, and a thermoelectric component is fixedly connected to the inner side of the inner core.

[0007] The thermoelectric component converts the heat energy generated by the inner core and the thermocouple coil into electrical energy to drive the motor. The motor works in conjunction with the heat absorption component to reduce damage to the outer insulation of the thermocouple coil. The heat exhaust channel works with the conveyor belt to promote the conversion of heat energy by the thermoelectric component.

[0008] Furthermore, a self-heating component is fixedly connected to the inner side of the power transmission frame, and an inductive component is fixedly connected to the outer side of the power transmission frame.

[0009] Furthermore, a heat insulation film is fixedly connected to the front of the two thermocouple coils, and two support feet are fixedly connected to the bottom of the two mounting plates located at the lower end of the inner core.

[0010] Furthermore, the self-heating component includes a thermoelectric component, with the two motors located on opposite sides of the front of the thermoelectric component, and the two heat dissipation channels fixedly connected to two mounting plates on the upper end of the inner core.

[0011] Furthermore, the thermoelectric assembly includes an internal compartment, with a heating plate fixedly sleeved in the middle of the inner side of the internal compartment. Two conductive strips are electrically connected to one side of the heating plate, and the two conductive strips are electrically connected to a motor. A cold end plate is electrically connected to one end of the two conductive strips. The cold end plate is located outside the internal compartment, and a PN connecting plate is electrically connected to one side of the cold end plate. A heat dissipation plate is electrically connected to one side of the PN connecting plate.

[0012] Furthermore, the heat absorption assembly includes fixing elements. Three fixing elements are fixedly connected to the inner side of the built-in compartment. An inner shaft is rotatably sleeved on the inner side of each of the three fixing elements. A fan wheel is fixedly sleeved on the side of one end of each of the three inner shafts.

[0013] Furthermore, the motor is fixedly connected to one side of the inner compartment, the drive shaft of the motor passes through the inner wall of the inner compartment and is located inside the inner compartment, a bevel gear is fixedly sleeved in the middle of the drive shaft of the motor, a side gear is fixedly connected to one end of an inner shaft located in the middle of one end of the inner compartment, the bevel gear meshes with the side gear, and a transmission chain is fixedly sleeved on the side of one end of the three inner shafts.

[0014] Furthermore, the heat exhaust channel includes two branch pipes, the bottom of the two branch pipes are fixedly connected to the top of the built-in compartment, the top of the two branch pipes are fixedly connected to a gas collection pipe, the top of the gas collection pipe is fixedly connected to a main pipe, a guide plate is fixedly connected to one side inside the main pipe, a rotating roller is rotatably connected to the top of the main pipe, one end of the rotating roller is located inside the main pipe, and a fan wheel is fixedly sleeved on the part inside the main pipe.

[0015] Furthermore, the inductive component includes four guide cylinders, which are respectively fixedly connected to the left and right corners of the upper ends of the two mounting plates at the upper end of the inner core and the left and right corners of the lower ends of the two mounting plates at the lower end of the inner core.

[0016] Furthermore, several conductor rods are fixedly connected to the side of the conveyor belt, and a drive roller is provided on the inner side of the top of the conveyor belt, with a rotating roller fixedly sleeved inside the drive roller.

[0017] The technical effects and advantages of this invention are as follows:

[0018] 1. When a high-power insulated power transmission device is in operation, the heat generated by the thermocouple coil and the inner core raises the temperature of the heated plate, creating a temperature difference between the heated plate and the cold end plate. The two are connected to form a closed circuit. The temperature difference between the different conductors further creates a potential difference, thereby generating a current. This current is used to drive the impeller of the motor. The rotation of the impeller generates wind power, which draws the heat around the coil and the inner core into the internal chamber, further raising the temperature of the heated plate. The larger the current generated, the higher the motor power. The two promote each other to dissipate heat from the coil and the inner core, solving the problem of the high temperature generated by the coil and the inner core softening or even burning the insulation film, avoiding the occurrence of partial discharge, and reducing the equipment failure rate.

[0019] 2. The heat-absorbing component draws in hot air from the built-in chamber, which then enters the gas-gathering pipe through branch pipes and is discharged through the main pipe. A guide vane inside the main pipe concentrates and guides the hot air towards the fan wheel, causing it to rotate. This rotation drives the drive roller, which in turn moves the conveyor belt along the side edge of the power transmission device. This causes the conductor rod to cut magnetic field lines, generating an induced current, which is then conducted to the circuit loop composed of the cold-end plate, PN connection plate, and heat-dissipating plate. Utilizing the semiconductor heat dissipation effect, the heat from the cold-end plate is transferred to the heat-dissipating plate via electrons, thus lowering the temperature of the cold-end plate. The heat from the heat-dissipating plate is then dissipated to the heated plate, further increasing the temperature difference between the cold-end plate and the heated plate, promoting circuit generation. This achieves a complementary effect between the self-heating component and the inductive component. Part of the coil's electric field energy is converted into electrical energy for use, weakening the electric field on the surface of the high-voltage conductor, avoiding the corona effect, and reducing energy loss.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The high-power insulated power transmission device involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1 The present invention provides a high-power insulated power transmission device, including a power transmission frame 1, a self-heating component 2 fixedly connected to the inner side of the power transmission frame 1, and an inductive component 3 fixedly connected to the outer side of the power transmission frame 1.

[0033] In this embodiment, it is necessary to further explain that the self-heating component 2 solves the problem of the high temperature generated by the coil and the inner core softening or even burning the insulating packaging film, avoids the occurrence of partial discharge, and reduces the equipment failure rate. The self-heating component 2 and the inductive component 3 promote each other, weaken the electric field on the surface of the high-voltage conductor, avoid the corona effect, and reduce energy loss. The specific structure and working principle of the above components will be explained in detail later.

[0034] Reference Figure 2 and Figure 3The power transmission frame 1 includes an inner core 101. Electrode coils 102 are fixedly sleeved on both sides of the inner core 101. Mounting plates 103 are fixedly connected to both sides of the front of the upper and lower ends of the inner core 101. A heat insulation film 104 is fixedly connected to the front of the two electrode coils 102. Two support legs are fixedly connected to the bottom ends of the two mounting plates 103 located at the lower end of the inner core 101.

[0035] In this embodiment, it is necessary to further explain that both of the electrocouple coils 102 have electrical connection ports on their back sides, one for transmitting electrical energy and the other for receiving electrical energy. The inner core 101 is made of a high-permeability material such as silicon steel sheet or ferrite, which can provide a low magnetic resistance path for the magnetic field. This allows the magnetic field generated by the receiving electrocouple coil 102 to be coupled to the transmitting electrocouple coil 102 through the inner core 101, thereby maximizing the transmission efficiency of magnetic flux. The electrocouple coil 102 has a high-voltage conductor coil inside and is wrapped with an insulating material. The insulating material is a polyolefin material, such as polyethylene or polypropylene. In this embodiment, the insulating material is polyethylene. The material of the heat insulation film 104 is also polyethylene, which is used to wrap the heat.

[0036] Reference Figure 4 The self-heating component 2 includes a thermoelectric component 201, which is fixedly connected to the inner side of the inner core 101. Two motors 202 are fixedly connected to the front of the thermoelectric component 201, and the two motors 202 are respectively located on both sides of the front of the thermoelectric component 201. Three heat-absorbing components 203 are fixedly connected to both ends of the inner side of the thermoelectric component 201. Two heat exhaust channels 204 are fixedly connected to the top of the thermoelectric component 201, and the two heat exhaust channels 204 are respectively fixedly connected to two mounting plates 103 at the upper end of the inner core 101.

[0037] In this embodiment, it should be specifically noted that the three heat-absorbing components 203 at both ends of the thermoelectric component 201 are arranged sequentially from top to bottom.

[0038] Reference Figure 5 The thermoelectric assembly 201 includes an inner chamber 2011, and a heating plate 2012 is fixedly sleeved in the middle of the inner side of the inner chamber 2011. Two conductive strips are electrically connected to one side of the heating plate 2012. The two conductive strips are electrically connected to a motor. One end of the two conductive strips is electrically connected to a cold end plate 2013. The cold end plate 2013 is located outside the inner chamber 2011.

[0039] In this embodiment, it should be specifically noted that the inner chamber 2011 is made of silicon-based composite material, and the heated plate 2012 and the cold end plate 2013 are conductors made of two different materials. The heated plate 2012, the conductive strip, and the cold end plate 2013 form a closed loop. When the temperature of the heated plate 2012 is higher than that of the cold end plate 2013, a potential difference is generated between them. Electrons in the loop tend to flow from the higher potential to the lower potential, thus generating a current. In this embodiment, the heated plate 2012 is made of copper, with a Seebeck coefficient of 1.5 μV / K and a conductivity of 59.610. 6 The S / m value has a thermal conductivity of 401 W / m·K. The cold end plate 2013 is a constantan plate with a Seebeck coefficient of 40-50 μV / K, an electrical conductivity of 2.2 S / m, and a thermal conductivity of 22 W / m·K.

[0040] Reference Figure 6 One side of the cold end piece 2013 is electrically connected to a PN connection plate 2014, and one side of the PN connection plate 2014 is electrically connected to a heat dissipation piece 2015.

[0041] In this embodiment, it should be specifically explained that the PN connection plate 2014 is made of semiconductor material, and the cold end plate 2013, the PN connection plate 2014, and the heat dissipation plate 2015 form a circuit loop. After power is applied, the current flows from the heat dissipation plate 2015 to the cold end plate 2013, while the electrons flow in the opposite direction. The electrons will carry away the heat from the cold end plate 2013 to the heat dissipation plate 2015, thereby reducing the temperature of the cold end plate 2013 and releasing heat in the heat dissipation plate 2015.

[0042] Reference Figure 7 and Figure 8 The heat absorption assembly 203 includes fixing elements 2031. Three fixing elements 2031 are fixedly connected to the inner side of the built-in chamber 2011. An inner shaft is rotatably sleeved on the inner side of each of the three fixing elements 2031. A fan wheel 2032 is fixedly sleeved on the side of one end of each of the three inner shafts. The motor 202 is fixedly connected to one side of the built-in chamber 2011. The drive shaft of the motor 202 passes through the inner wall of the built-in chamber 2011 and is located inside the built-in chamber 2011. A bevel gear is fixedly sleeved in the middle of the drive shaft of the motor 202. A side gear is fixedly connected to one end of an inner shaft located in the middle of one end of the built-in chamber 2011. The bevel gear meshes with the side gear. A transmission chain 2033 is fixedly sleeved on the side of one end of each of the three inner shafts.

[0043] In this embodiment, it is necessary to specifically explain that the transmission chain 2033 drives the three inner shafts to rotate synchronously. The three heat-absorbing components 203 have the same structure on the other side of the inner chamber 2011. The inner core 101, together with the thermoelectric component 101, the motor 202, and the heat-absorbing component 203, form a magnetic core.

[0044] When the high-power insulated power transmission device is in operation, the heat generated by the thermocouple coil 102 and the inner core 101 raises the temperature of the heated plate 2012, creating a certain temperature difference between the heated plate 2012 and the cold end plate 2013. The two are connected to form a closed circuit. The temperature difference between the different conductors further creates a potential difference, thereby generating a current. This current is used by the motor 202 to drive the fan wheel 2032. The rotation of the fan wheel 2032 generates wind power, which draws the heat around the inner core 101 and the thermocouple coil 102 into the internal chamber 2011, further raising the temperature of the heated plate 2012. The larger the current generated, the higher the power of the motor 202. The two mutually promote heat dissipation of the inner core 101 and the thermocouple coil 102, solving the problem of the high temperature generated by the inner core 101 and the thermocouple coil 102 softening or even burning the insulating packaging film, avoiding the occurrence of partial discharge phenomenon, and reducing the equipment failure rate.

[0045] Reference Figure 9 The heat exhaust channel 204 includes two branch pipes 2041. The bottom of the two branch pipes 2041 is fixedly connected to the top of the built-in chamber 2011. The top of the two branch pipes 2041 is fixedly connected to a gas collection pipe 2042. The top of the gas collection pipe 2042 is fixedly connected to a main pipe 2043. A guide plate is fixedly connected to one side of the inside of the main pipe 2043. A rotating roller 2044 is rotatably connected to the top of the main pipe 2043. One end of the rotating roller 2044 is located inside the main pipe 2043, and a fan wheel 2045 is fixedly sleeved on the part located inside the main pipe 2043.

[0046] The heat absorption component 203 draws in hot air from the built-in chamber 2011, which then enters the gas collection pipe 2042 through the branch pipe 2041, and is then discharged through the main pipe 2043. The main pipe 2043 is equipped with a guide vane to concentrate and guide the hot air towards the fan wheel 2045, causing the fan wheel 2045 to rotate and drive the rotating roller 2044 to rotate.

[0047] In this embodiment, it should be specifically noted that the angle between the air guide plate and the inner wall of one side of the main pipe 2043 is between 45° and 60°, ensuring that the hot airflow flowing through the main pipe 2043 is blown to one end of the fan wheel 2045, causing it to rotate.

[0048] Reference Figure 10 The inductive component 3 includes four guide cylinders 301. The four guide cylinders 301 are respectively fixedly connected to the left and right corners of the upper ends of the two mounting plates 103 at the upper end of the inner core 101 and the left and right corners of the lower ends of the two mounting plates 103 at the lower end of the inner core 101. A conveyor belt 302 is movably sleeved on the side of the guide cylinder 301. Several conductor rods are fixedly connected to the side of the conveyor belt 302. A drive roller 303 is provided on the inner side of the top of the conveyor belt 302. A rotating roller 2044 is fixedly sleeved inside the drive roller 303.

[0049] The rotation of the roller 2044 drives the drive roller 303 to rotate, which in turn causes the conveyor belt 302 to move along the side edge of the power transmission device. This causes the conductor rod to cut the magnetic field lines and generate an induced current, which is conducted to the circuit loop composed of the cold end plate 2013, the PN connection plate 2014, and the heat dissipation plate 2015. The heat from the cold end plate 2013 is transferred to the heat dissipation plate 2015 through electrons, thereby reducing the temperature of the cold end plate 2013. The heat from the heat dissipation plate 2015 is dissipated to the heated plate 2012, further increasing the temperature difference between the cold end plate and the heated plate, promoting the generation of the circuit, and achieving the complementary effect of the self-heating component 2 and the inductive component 3. The electric field energy of the coil is partially converted into electrical energy for use, which weakens the electric field on the surface of the high-voltage conductor, avoids the corona effect, and reduces energy loss.

[0050] In this embodiment, it should be specifically noted that the surface friction coefficient of the drive roller 303 is between 1.1 and 1.3. The rotation of the drive roller 303 can drive the conveyor belt 302 to move. Each conductor rod is electrically connected to the cold end plate 2013 to provide power for the semiconductor heat dissipation of the cold end plate 2013. The circuit connection is a conventional technical means, so it is not shown in the figure.

[0051] The working principle of this invention is as follows: The heat generated by the thermocouple coil 102 and the inner core 101 raises the temperature of the heated plate 2012, creating a certain temperature difference between the heated plate 2012 and the cold end plate 2013. The two are connected to form a closed circuit. The temperature difference between the different conductors further creates a potential difference, thereby generating a current. This current is used by the motor 202 to drive the fan wheel 2032. The rotation of the fan wheel 2032 generates wind power, which draws the heat around the inner core 101 and the thermocouple coil 102 into the built-in chamber 2011, further raising the temperature of the heated plate 2012. The larger the current generated, the higher the power of the motor 202. The two mutually promote heat dissipation of the inner core 101 and the thermocouple coil 102, solving the problem of the high temperature generated by the inner core 101 and the thermocouple coil 102 softening or even burning the insulating packaging film, avoiding the occurrence of partial discharge phenomenon, and reducing the equipment failure rate.

[0052] The heat-absorbing component 203 draws in hot air from the built-in chamber 2011, which then enters the gas-collecting pipe 2042 through the branch pipe 2041, and is then discharged through the main pipe 2043. The main pipe 2043 contains a guide vane that concentrates and guides the hot air towards the fan wheel 2045, causing it to rotate. The rotation of the fan wheel 2045 drives the drive roller 303 to rotate, which in turn causes the conveyor belt 302 to move along the side edge of the power transmission device. This causes the conductor rod to cut magnetic field lines, generating an induced current, which is then conducted to the cold end plate 2013, the PN connection plate 2014, and the heat-dissipating plate 2. In the circuit loop composed of 015, the heat of the cold end plate 2013 is transferred to the heat dissipation plate 2015 through electrons by utilizing the heat dissipation effect of semiconductors, thereby reducing the temperature of the cold end plate 2013. The heat of the heat dissipation plate 2015 is dissipated to the heat receiving plate 2012, further increasing the temperature difference between the cold end plate and the heat receiving plate, promoting the generation of the circuit, and achieving the complementary effect of the self-heating component 2 and the inductive component 3. The electric field energy of the coil is partially converted into electrical energy for use, which weakens the electric field on the surface of the high voltage conductor, avoids the corona effect, and reduces energy loss.
