Description

Technical Field

[0001] This utility model relates to the field of protection device technology, specifically to a PT parallel protection device with active heat dissipation. Background Technology

[0002] PT parallel protection devices are important equipment used for monitoring and protection in power systems. Especially when dealing with voltage transformer faults or maintenance, the core function of PT parallel protection devices is to ensure that when a PT on a busbar is faulty or under maintenance, that busbar can still maintain the supply of voltage signals. Through the parallel device, the PT signal of another normally operating busbar can be transmitted to the voltage busbar of the faulty or under maintenance section, thereby ensuring that the electrical equipment and protection system on the busbar can continue to operate normally and will not be interrupted or malfunction due to the loss of voltage signals.

[0003] Chinese patent CN217721882U discloses a microcomputer-based parallel measurement and control device, comprising: a measurement and control device body; a fixed box mounted on the top of the measurement and control device body, the fixed box having a hollow structure and communicating with the interior of the measurement and control device body; heat dissipation holes with a fan-shaped structure on both side walls of the measurement and control device body, and a filter screen installed inside the heat dissipation holes; a cleaning mechanism installed on both side walls of the measurement and control device body at the heat dissipation holes; and a drive mechanism for driving the cleaning mechanism installed inside the measurement and control device body. This invention uses heat dissipation holes on the surface of the measurement and control device for heat dissipation, a filter screen for filtering the incoming air, and a cleaning mechanism to clean the surface of the filter screen. The cleaned dust falls into a dust collection box for storage, facilitating dust disposal. The internal drive mechanism drives the cleaning mechanism to repeatedly swing, achieving an automatic cleaning effect and improving the stability of the measurement and control device.

[0004] However, the above solution has the following problems when implementing the relevant technology: the heat dissipation efficiency is limited. It relies solely on the heat dissipation holes for natural convection heat dissipation, which is inefficient. Especially in high-power or enclosed environments, it may not be able to effectively reduce the internal temperature. Therefore, a PT parallel protection device with active heat dissipation is needed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0034] Please see Figure 1-5 This utility model is a PT parallel protection device with active heat dissipation, including a device body 100 and a heat dissipation component 200. The heat dissipation component 200 includes two air cooling mechanisms 201, two heat conduction mechanisms 202 and a detection mechanism 203.

The detection mechanism 203 includes a temperature sensor 2031 and a control module 2032.

[0035] Specifically, two air-cooling mechanisms 201 are symmetrically fixedly installed on the two side walls of the device body 100, two heat-conducting mechanisms 202 are symmetrically installed on one side of the device body 100, a detection mechanism 203 is fixedly installed on the inner bottom wall of the device body 100, a T-shaped shell 2011 is fixedly installed through the device body 100, two pairs of fixing plates 2012 are respectively fixedly installed on the upper and lower sides of the inner wall of the T-shaped shell 2011, two cooling fans 2013 are respectively inserted into the inner side of the two pairs of fixing plates 2012, and the cooling fans 2013 are fixedly installed on the fixing plates 2012 by screws, and two filters 2014 are both fixedly installed on the inner side wall of the T-shaped shell 2011. 2014 is located on the front and rear sides of the cooling fan 2013. The heat conduction plate 2021 is fixedly installed on one side of the inner wall of the device body 100. Multiple heat dissipation blocks 2022 are provided, and multiple heat dissipation blocks 2022 are fixedly installed on one side of the heat conduction plate 2021 from top to bottom. The air duct 2023 is opened on the heat conduction plate 2021. The through hole 2024 is opened on the heat dissipation block 2022, and the through hole 2024 is connected to the air duct 2023. The temperature sensor 2031 and the control module 2032 are both fixedly installed on the inner bottom wall of the device body 100. The temperature sensor 2031 and the cooling fan 2013 are both electrically connected to the control module 2032.

[0036] The operation process of this embodiment is as follows: During use, heat is conducted to the heat sink 2022 through the heat conduction plate 2021, and then the heat is dissipated through the heat sink 2022. Then, external natural air can enter the air duct 2023 through the through hole 2024, thereby dissipating heat inside the heat conduction plate 2021 and the heat sink 2022, thus improving the heat dissipation effect of the heat conduction plate 2021 and the air duct 2023 and increasing the heat dissipation efficiency. At the same time, the temperature sensor 2031 detects the stability inside the device body 100. When the stability of the device body 100 reaches or exceeds a preset value, the control module 2032 controls the cooling fan 2013 to turn on, thereby accelerating the airflow inside the device body 100, speeding up the heat dissipation process, and effectively reducing the internal temperature of the device. In addition, with the cooperation of two filters 2014, dust and particulate matter in the air can be effectively blocked from entering the device body 100, reducing the contamination of electronic components, thereby improving the reliability and service life of the device. Specific Implementation Example 2

[0037] Please see Figure 1-4Based on the first specific embodiment, a cleaning component 300 is installed on the device body 100. The cleaning component 300 is in contact with the heat dissipation component 200. The cleaning component 300 includes two brush mechanisms 301 and two drive mechanisms 302. The brush mechanism 301 includes a rotating rod 3011, a strip plate 3012 and a brush 3013. The drive mechanism 302 includes a motor 3021, a fixed plate 3022, a force transmission rod 3023, a rocker arm 3024 and a connecting rod 3025.

The connecting plate is fixedly installed on the end of the rotating rod 3011 away from the strip plate 3012, and the round rod is fixedly installed on one side of the connecting plate. The end of the force transmission rod 3023 away from the connecting rod 3025 is rotatably connected to the round rod.

[0038] Specifically, two brush mechanisms 301 are respectively installed on the two side walls of the device body 100, with one side of each brush mechanism 301 contacting the outer filter screen 2014. Two drive mechanisms 302 are respectively installed on the two side walls of the inner wall of the device body 100, and are connected to the brush mechanisms 301. A rotating rod 3011 is installed through the device body 100 and is rotatably connected to it. A strip plate 3012 is fixedly installed at one end of the rotating rod 3011, and a brush 3013 is fixedly installed on the strip plate. On one side of 3012, and on the side of brush 3013 away from strip plate 3012, it is in contact with filter screen 2014 located on the outside. Motor 3021 is fixedly installed on the inner wall of device body 100 by motor frame. Fixed plate 3022 is fixedly connected to the output end of motor 3021.

Rocker arm 3024 is fixedly installed on the other end of rotating rod 3011. The other end of force transmission rod 3023 is rotatably connected to rocker arm 3024.

[0039] The operation process of this embodiment is as follows: the fixed disk 3022 is driven to rotate by the motor 3021. Then, the rotating fixed disk 3022 pushes and pulls the force transmission rod 3023 back and forth through the connecting rod 3025 on it. Thus, under the action of the rocker arm 3024, the force transmission rod 3023 can drive the rotating rod 3011 and the strip plate 3012 to rotate and swing back and forth. This allows the brush 3013 to clean the outermost filter screen 2014, thereby restoring the filtration efficiency of the filter screen 2014, better capturing and intercepting pollutants in the air, reducing airflow resistance, ensuring smooth airflow, and maintaining efficient heat dissipation performance.
