Description

Technical Field

[0001] This utility model relates to the field of basic electrical components technology, and in particular to a power supply device for power distribution network line conductors. Background Technology

[0002] In modern power distribution systems, with the continuous advancement of intelligence, many devices such as fault indicators, FTUs (feeder terminal units), and DTUs (distribution terminal units) require a stable and reliable power supply to monitor the operation status of the power distribution network in real time, achieve rapid fault location and isolation, and thus improve power supply reliability. As a key component for supplying power to these devices, the performance of the power supply device for the power supply line conductors directly affects the level of intelligent operation of the entire power distribution system.

[0003] Among them, the CTP current extraction device is a device based on the current transformer (CT) power extraction technology. Its working principle is to extract power from the magnetic field generated by the load current of the conductor and to perform power isolation and transformation through the principle of electromagnetic induction. The device is usually composed of a power extraction CT (energy extraction transformer) and a power conversion module. It can effectively solve the problem that some equipment in the distribution network cannot work normally due to the lack of conventional power supply measures, and has been widely used in the field of high voltage power transmission and distribution.

[0004] In actual operation, CTP current extraction devices face the challenge of heat dissipation. As the device generates heat during power extraction and power conversion, if the heat cannot be dissipated in time, the internal temperature of the device will become too high. Excessive temperature will affect the performance and lifespan of the electronic components inside the device, reduce the reliability and stability of the device, and long-term exposure to high temperature may cause device failure, thereby affecting the normal operation of the entire power distribution network. Utility Model Content

This device can solve the problem that the device generates heat during power supply and power conversion. If the heat cannot be dissipated in time, the internal temperature of the device will be too high. The excessively high temperature will affect the performance and life of the electronic components inside the device, reduce the reliability and stability of the device, and long-term exposure to high temperature may cause device failure, thereby affecting the normal operation of the entire power distribution network.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power extraction device for power distribution network conductors, comprising a CTP current extraction device body and an electromagnetic induction power extraction component, wherein a heat dissipation component is provided on the CTP current extraction device body;

Four fixing bolts 7 are threaded onto the outer wall of the mounting base at the lower end of the heat dissipation fins 6. Four fixing bolt grooves 8 are formed inside the upper end of the CTP current-generating device body 1. The heat dissipation fins 6 are installed inside the upper end of the CTP current-generating device body 1 by the four fixing bolts 7 respectively engaging with the corresponding fixing bolt grooves 8. The outer walls of the two first T-shaped blocks 9 are slidably connected to the interior of the corresponding first T-shaped block grooves 5. The heat dissipation fins 6 are located inside the air guide shroud 3. The multiple air guide plates 2 form a guiding area on the air guide shroud 3. Two conical block grooves 15 are formed on the outer wall of the end of the shroud 3 away from the first T-shaped block 9. The interior of each of the two conical block grooves 15 is provided with a second fixing bolt groove 12. The inner walls of both sides of the CTP current extraction device body 1 away from the first T-shaped block groove 5 are provided with second T-shaped block grooves 11. The outer walls of both sides of the limiting plate 10 are fixedly connected with second T-shaped blocks 13.

The ends of the two second fixing bolts 14 near the second fixing bolt grooves 12 are threadedly extended into the interior of the conical block grooves 15 and are threadedly connected to the interior of the corresponding second fixing bolt grooves 12.

[0033] The CTP current extraction device body 1 has mounting plates on both sides of its lower end. The electromagnetic induction power extraction component 4 is connected to the CTP current extraction device body 1 via a connecting line. The CTP current extraction device body 1 and the electromagnetic induction power extraction component 4 are electrically connected. The electromagnetic induction power extraction component 4 consists of an energy extraction transformer core, an energy extraction coil, and an insulating shell.

[0034] Furthermore, when using this device, during the installation of the power supply device for the power distribution line conductor, firstly, the main body 1 of the CTP current extraction device is fixed to a suitable position on the power distribution line using the mounting plates on both sides of the lower end. Next, the heat dissipation fins 6 are installed using four fixing bolts 7 in conjunction with the fixing bolt grooves 8 inside the upper end of the main body 1 of the CTP current extraction device, ensuring the heat dissipation fins 6 are securely installed on the upper end of the main body 1 of the CTP current extraction device. Then, the two first T-shaped blocks 9 of the air guide shroud 3 are respectively inserted into the first T-shaped block grooves 5 on both sides of the upper end of the main body 1 of the CTP current extraction device, initially fixing the air guide shroud 3 onto the main body 1 of the CTP current extraction device. At this time, the heat dissipation fins 6 are located inside the air guide shroud 3. Next, the two second T-shaped blocks 13 of the limiting plate 10 are respectively inserted into the second T-shaped block grooves 11 on both sides of the end of the main body 1 of the CTP current extraction device away from the first T-shaped block grooves 5, allowing the limiting plate 10 to slide on the main body 1 of the CTP current extraction device.

When the device is running, the core of the energy harvesting transformer of the electromagnetic induction power harvesting component 4 is wrapped around the power distribution network line conductor. When current flows through the conductor, according to the principle of electromagnetic induction, an induced electromotive force is generated in the energy harvesting coil, thereby obtaining electrical energy, which is transmitted to the CTP current harvesting device body 1 through the connecting line. During this process, the CTP current harvesting device body 1 will generate heat. At this time, the heat dissipation component starts to work. Under the guidance of the air guide area formed by multiple air guide plates 2, the outside air flows orderly through the heat dissipation fins 6 inside the air guide shroud 3. The heat dissipation fins 6 increase the contact area with the air, accelerate the heat transfer, and the air carries away the heat, thereby achieving heat dissipation of the CTP current harvesting device body 1 and ensuring stable operation of the device.

[0035] The CTP current-generating device body 1 generates heat through the heat dissipation assembly. At this time, the heat dissipation assembly starts to work. Under the guidance of the air guide area formed by multiple air guide plates 2, the outside air flows orderly through the heat dissipation fins 6 inside the air guide cover 3. The heat dissipation fins 6 increase the contact area with the air, accelerate the heat transfer, and the air carries away the heat, thereby achieving heat dissipation of the CTP current-generating device body 1 and ensuring stable operation of the device. This effectively improves the service life of the CTP current-generating device body 1 and avoids device failure caused by the CTP current-generating device body 1 being in a high-temperature environment for a long time.
