Description
Technical Field
[0001] This invention belongs to the technical field of high voltage testing equipment, specifically relating to an intelligent temperature control and heat dissipation system for the control box of a partial discharge tester. Background Technology
[0002] The tester is a key device for evaluating the insulation condition of a generator. Its control box integrates various high-power electrical components such as silicon rectifiers, transformers, and power resistors, generating a significant amount of heat during operation. Poor heat dissipation will cause the internal temperature to rise continuously, leading to a series of problems: 1) High temperatures accelerate the aging of components such as electrolytic capacitors, shortening the equipment's lifespan; 2) The parameters of semiconductor components (such as operational amplifiers) change with temperature, causing unstable measurement references and affecting the accuracy of test data; 3) In extreme cases, overheating may cause component burnout or protective shutdown, affecting important testing tasks; 4) Currently, the common heat dissipation method is to drill holes in the enclosure and install continuously running fans. While effective, this method introduces new problems: continuously running fans have a short lifespan, consume a lot of energy and generate significant noise, and easily attract dust, which in the long run can negatively impact heat dissipation and internal cleanliness due to dust accumulation.
[0003] To address the aforementioned issues, it is necessary to propose a rationally designed and effective intelligent temperature control and heat dissipation system for the control box of a partial discharge tester. Summary of the Invention

[0015] Figure 1 This is a partial structural schematic diagram of an intelligent temperature control and heat dissipation system for a partial discharge tester control box according to an embodiment of the present invention. Figure 2This is a partial structural schematic diagram of an intelligent temperature control and heat dissipation system for a partial discharge tester control box according to another embodiment of the present invention. Detailed Implementation
[0016] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] like Figure 1 and Figure 2 As shown, the present invention provides an intelligent temperature control and heat dissipation system 100 for a partial discharge tester control box, including a control box body 110, a cooling fan 120 and a main control module 130.
[0018] The control box 110 is provided with an air inlet 111 and an air outlet 112; wherein the positions of the air inlet 111 and the air outlet 112 are matched to form an effective air convection channel.
[0019] The cooling fan 120 is located at the air inlet 111 or the air outlet 112, and the cooling fan 120 cools down the inside of the control box 110.
[0020] The main control module 130 is electrically connected to the cooling fan 120, and the main control module 130 includes a time control unit 131 and a temperature control unit 132.
[0021] The timing control unit 131 is used to control the periodic start and stop of the cooling fan 120. For example, the timing control unit 131 can turn on the cooling fan 120 before the tester starts working each day and turn off the cooling fan 120 after the tester finishes working, thereby achieving predictive heat dissipation, avoiding ineffective operation of the cooling fan 120, and saving energy.
[0022] The temperature control unit 132 is used to monitor the temperature inside the control box 110 in real time and forcibly start the cooling fan 120 when the temperature exceeds a preset temperature threshold. Through the temperature control unit 132, the temperature inside the control box can be monitored in real time, and when the temperature exceeds a safe temperature threshold, regardless of the state of the time control unit 132, the temperature control unit 132 will forcibly turn on the cooling fan 120 to provide guaranteed heat dissipation for the control box. The intelligent temperature-controlled heat dissipation system for a partial discharge tester control box of the present invention achieves a dual mechanism of preventive and emergency heat dissipation by integrating a time control unit and a temperature control unit in the main control module. The time control unit can periodically start and stop the fan according to a preset plan to avoid long-term ineffective operation, thereby achieving energy saving, noise reduction, and extending the life of the cooling fan; the temperature control unit detects the temperature inside the control box and forces the cooling fan to start for heat dissipation when the temperature is abnormal, thereby effectively preventing the control box from overheating and being damaged, improving measurement accuracy and overall operational reliability, and solving the shortcomings of traditional single continuous heat dissipation or single temperature control modes.
[0023] For example, such as Figure 1 As shown, the main control module 130 also includes a mode switching switch 133; the mode switching switch 133 is used to switch different control modes according to the operating environment inside the control box 110. Specifically, the control modes include pure time control mode, pure temperature control mode, or time-temperature coordinated mode. That is to say, the mode switching switch 133 can select a specific heat dissipation method according to the specific working environment inside the control box 110, such as heat dissipation only through the time control unit 131, or heat dissipation only through the temperature control unit 132, etc.
[0024] In this embodiment, the appropriate control mode is selected by switching the mode, which enhances the adaptability and operational flexibility of the heat dissipation system. The most suitable heat dissipation strategy can be selected according to the actual working conditions and environmental conditions of the control box, so that the heat dissipation system can not only cope with normal stable working conditions, but also adapt to special or changing working scenarios, thereby improving the practicality of the system and the user experience.
[0025] For example, in this embodiment, the temperature control unit 132 includes a temperature sensor and a comparison circuit; the temperature sensor is used to collect the real-time temperature inside the control box; the comparison circuit is used to compare the real-time temperature with a preset temperature threshold.
[0026] In this embodiment, a reliable and direct temperature control feedback mechanism is established through a temperature sensor and a comparison circuit forming a temperature control unit. The structure is simple and the response is rapid, ensuring the real-time and accuracy of temperature control intervention and providing overheat protection for the heat dissipation system.
[0027] For example, in this embodiment, there are multiple temperature sensors, which are disposed at different heating elements inside the control box 110.
[0028] In this embodiment, temperature sensors are installed at different heating elements inside the control box to achieve zoned temperature monitoring within the control box and ensure the normal operation of different heating elements.
[0029] For example, in this embodiment, the timing control unit 131 may include a microprocessor-based digital timer or a mechanical time relay for setting multiple daily start and stop times for the cooling fan 120.
[0030] It should be noted that, in this embodiment, the specific composition of the timing unit 131 is not specifically limited, and can be selected according to actual needs, as long as it can turn on the cooling fan 120 at a time.
[0031] In this embodiment, the intermittent operation of the cooling fan is replaced by the continuous operation of the cooling fan in the prior art by the time control unit, which significantly reduces power consumption and conforms to the concept of green environmental protection. It not only extends the service life of the cooling fan itself, but more importantly, it delays the thermal aging of the core components in the control box by effectively controlling the temperature, thereby improving reliability. In addition, it reduces the unnecessary running time of the cooling fan, reduces noise and dust intake, and keeps the environment inside the box clean.
[0032] For example, in this embodiment, the cooling fan 120 can be a stepless speed-regulating fan; the main control module 130 adjusts the speed of the cooling fan 120 according to the monitored temperature inside the control box 110.
[0033] Specifically, when the temperature is not high, the cooling fan 120 is controlled to run at a low speed to further reduce noise and energy consumption, and when the temperature rises, the cooling fan 120 is controlled to increase its speed to enhance heat dissipation capacity, thereby achieving a better balance between heat dissipation efficiency, quiet operation and energy saving.
[0034] For example, such as Figure 1 As shown, in this embodiment, the main control module 130 further includes an alarm unit 134; the alarm unit 134 is used to issue an alarm signal when the cooling fan 120 malfunctions. The alarm signal can be an audible alarm, for example, emitting a whistle to alert the user when the cooling fan malfunctions, reminding them to check the cooling fan's operating status. The alarm signal can also be a visual alarm, for example, the alarm unit 134 emits a green light when the cooling fan is operating normally, and a red light when the cooling fan malfunctions, reminding the user to check the cooling fan's operating status.
[0035] It should be noted that this embodiment does not specifically limit the alarm method of the alarm unit, and can be selected according to actual needs.
[0036] In this embodiment, by setting up an alarm unit, when the cooling fan malfunctions (such as stopping or jamming), the alarm unit can issue an alarm in a timely manner to remind the user to perform maintenance, thereby avoiding the risk of equipment overheating and damage due to heat dissipation failure and enhancing the reliability of the tester control box.
[0037] For example, such as Figure 1 As shown, in this embodiment, the main control module 130 further includes a wireless communication unit 135; the wireless communication unit 135 is used for remote real-time monitoring, parameter setting, and mode switching.
[0038] Specifically, the wireless communication unit 135 can use wireless communication methods such as Wi-Fi, Bluetooth, or LoRa to connect to a host computer or mobile APP, enabling remote real-time monitoring, parameter setting, and mode switching. The wireless communication module is integrated into the main control module, and supporting monitoring software is developed to support cloud data storage and analysis.
[0039] In this embodiment, by integrating a wireless communication unit, remote intelligent management of the heat dissipation system is realized; users or maintenance personnel can remotely monitor the temperature and fan status inside the control box, and adjust the control parameters and modes without on-site operation; this greatly improves the manageability and convenience of the equipment.
[0040] For example, in this embodiment, a dustproof net is provided at the air inlet 111, and an air guide shroud is provided at the air outlet 112. The dustproof net effectively reduces the entry of dust and debris into the housing, keeps the interior clean, and prevents dust accumulation from affecting heat dissipation and circuit safety; the air guide shroud helps to guide airflow in a directional and smooth manner, improves heat dissipation efficiency, and may also reduce airflow noise.
[0041] This invention relates to an intelligent temperature-controlled heat dissipation system for a partial discharge tester control box. It aims to solve problems in existing tester control boxes caused by excessive internal temperature, accelerated component aging, decreased measurement accuracy, and poor stability due to the heat generated by high-power components such as silicon rectifiers. The system innovatively integrates a dual-mode drive circuit that coordinates a time control unit and a temperature control unit to control the cooling fan. This meets the heat dissipation requirements of normal operation while providing safety assurance against sudden high temperatures, demonstrating a high degree of intelligence. Furthermore, the heat dissipation system can not only achieve preventative cooling by timed start and stop of the fan according to a preset time using the time control unit, but also significantly reduce energy consumption by replacing continuous operation with intermittent operation. This system is energy-efficient and aligns with green environmental protection principles. It not only extends the lifespan of the fan itself, but more importantly, it effectively slows down the thermal aging of core components inside the enclosure through temperature control, improving overall reliability. It reduces unnecessary cooling fan operation time, thereby lowering overall noise and reducing dust intake, keeping the enclosure clean. Furthermore, the temperature control unit monitors the enclosure temperature in real time and forces cooling to activate when the temperature exceeds the limit, achieving a balance between energy saving, noise reduction, and precise, efficient heat dissipation. This cooling system effectively improves the reliability and lifespan of the partial discharge tester under long-term, continuous operation. It offers multiple operating modes to adapt to different usage environments and working conditions.
[0042] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
