Description

Technical Field

[0001] The utility model relates to the technical field of nuclear phase meter verification, and specifically relates to a nuclear phase meter verification device. Background Art

[0002] Nuclear phase refers to using instruments or other means in the power system to check whether the phases and phase sequences of two power sources or loops are the same, that is, in the actual operation of electric power, the measurement of the phase difference. However, the quality of various nuclear phase meters on the market varies, so it has become an urgent task to verify and calibrate this instrument. The high-voltage nuclear phase meter verification and calibration device is the equipment for verifying and calibrating the above-mentioned instrument.

[0003] After retrieval, the patent with the publication number CN115616465A discloses a performance parameter test system for a high-voltage nuclear phase detector. Although two nuclear phase detectors are set to test the signals after boosting during use, and the standard phase volt-ampere meter is used to detect the signals after voltage division; the control host determines whether the phases of the two nuclear phase detectors are in-phase or out-of-phase, and then compares and analyzes them with the signals detected by the standard phase volt-ampere meter respectively to verify whether the functions of the nuclear phase detector are correct. However, when this device is in use, the internal electronic components will generate heat due to the passing of current. If these heats cannot be dissipated in time, it will cause the internal temperature of the device to rise. When the temperature exceeds the rated working temperature of the components, it may have an adverse effect on the performance of the components, and even cause component damage. Moreover, when the device works in a high-temperature environment, the performance of the internal electronic components may change slightly due to temperature changes, resulting in errors in the verification results. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a nuclear phase meter verification device, which solves the problems mentioned in the background art.

[0005] The solution of the utility model to the above technical problems is as follows:

[0006] The nuclear phase meter verification device includes a base, on which an upper cover is rotatably installed through a hinge, and a verification instrument body is installed inside the base.

[0007] The calibrator body is provided with a touch screen, and a grounding interface and an output interface are provided on one side of the touch screen of the calibrator body. A switch module is installed on the side of the touch screen away from the grounding interface of the calibrator body, and an emergency stop switch is installed on the calibrator body below the switch module. A first receiving groove is provided on the calibrator body above the touch screen, and a second receiving groove is provided on the side of the touch screen away from the first receiving groove of the calibrator body. Hollow plates are provided at the bottom ends of the first receiving groove and the second receiving groove. A cooling fan is installed at the bottom end of the first receiving groove of the calibrator body, and cooling fins are installed on the bottom surface of the calibrator body between the second receiving groove and the first receiving groove.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, the calibrator body is supported and installed in the base through heat dissipation fins.

[0010] The beneficial effects of adopting the above further scheme are:

[0011] As a medium for heat conduction, the heat sink fins can effectively transfer the heat generated inside the calibrator body to the external environment. By supporting the installation of the calibrator body with the heat sink fins, it can be ensured that the heat can be quickly and evenly distributed on the fins, thereby increasing the heat dissipation area and improving the heat dissipation efficiency. This design helps to reduce the operating temperature of the calibrator body, prevent performance degradation or damage due to overheating, and ensure the stability and reliability of the equipment under long-term, high-load operation. Using heat sink fins as a supporting structure can simplify the overall design of the device and reduce additional supporting components and installation steps. This integrated design not only saves space, but also makes the structure of the device more compact and beautiful. At the same time, the layout of the heat sink fins can be optimized according to the needs of heat conduction to ensure that heat can flow along a predetermined path, further improving the heat dissipation effect.

[0012] Furthermore, a cavity is left between the bottom end of the base and the calibrator body, and the first accommodating groove and the second accommodating groove are both connected to the cavity between the calibrator body and the base through the hollow plate.

[0013] The beneficial effects of adopting the above further scheme are:

[0014] The cavity between the base and the body of the calibrator, together with the connection between the first and second receiving grooves through the perforated plate, jointly form an effective air circulation channel. This channel enables the cooling fan to smoothly draw external cold air into the device, conduct heat exchange through the heat dissipation fins, and then discharge the warm air, thereby achieving effective heat transfer and dissipation. Due to the existence of the air circulation channel, the working effect of the cooling fan is significantly improved. The cold air can flow through the heat dissipation fins more quickly, taking away more heat, while the warm air can also be discharged more smoothly outside the device, avoiding heat accumulation. This efficient heat dissipation mechanism helps to reduce the working temperature of the calibrator body and ensure the stable operation of the device.

[0015] Furthermore, the first and second receiving grooves are used to store wiring tools such as cables used in the calibration.

[0016] The beneficial effects of adopting the above further solution are:

[0017] During the calibration process, various cables and wiring tools are often needed. If these tools are placed randomly, they will not only occupy a large amount of working space but also increase the time to find and retrieve the tools. By storing the cables and wiring tools in the first and second receiving grooves, users can quickly find the required tools, thereby improving work efficiency. When the cables and wiring tools are not in use, if they are placed randomly or exposed to the external environment, they are easily damaged or contaminated. The design of the receiving grooves can effectively protect these tools from dust, moisture, and other potential hazards, extending their service life. At the same time, properly storing the cables and wiring tools can also reduce their accidental collision and scratching of the calibrator body or other devices, protecting the integrity and stability of the devices.

[0018] Furthermore, the cooling fan draws external air from the second receiving groove into the cavity between the calibrator body and the base, and after the external air flows through the heat dissipation fins, it is discharged from the base through the cooling fan at the first receiving groove.

[0019] The beneficial effects of adopting the above further solution are:

[0020] This design enables the cooling fan to directly introduce external cold air into the cavity between the calibrator body and the base. When these cold air flows through the heat dissipation fins, it can quickly absorb and carry away the heat. Subsequently, the warm air is discharged from the first receiving groove through the cooling fan, thus forming an efficient heat dissipation cycle. This design ensures that the calibrator body can maintain a relatively low temperature during operation, preventing performance degradation or damage caused by overheating. By setting the second receiving groove as the air inlet and the first receiving groove as the air outlet, the designer has planned a clear and efficient air flow path for the heat dissipation system. This design not only reduces the resistance of air flow but also improves the working efficiency of the cooling fan. At the same time, it also helps to ensure that the heat on the heat dissipation fins can be evenly and quickly dissipated into the external environment.

[0021] Furthermore, there are two output interfaces respectively, and the two output interfaces are symmetrically distributed on both sides of the grounding interface.

[0022] The beneficial effects of adopting the above further scheme are:

[0023] The symmetrically distributed output interfaces make it more convenient and faster for users to connect external devices or cables. No matter from which direction the user approaches the device, they can easily find and connect to the output interfaces without adjusting the device position or rotating the interface direction. By symmetrically arranging the two output interfaces on both sides of the grounding interface, the designer effectively utilizes the space of the device. This layout not only maintains the compactness of the device but also avoids interference and conflicts between the interfaces, improving the rationality of the overall layout. As a key part of safety grounding, the position of the grounding interface is crucial for the safety of the entire device. Setting the two output interfaces at symmetric positions on both sides of the grounding interface helps to ensure a good grounding state while connecting external devices, thus improving the safety performance of the device.

[0024] Furthermore, one of the output interfaces is an X-phase / A-phase output interface, and the other output interface is a Y-phase / B-phase output interface.

[0025] The beneficial effects of adopting the above further scheme are:

[0026] This design method directly clarifies the phase attributes of the two output interfaces, namely X-phase / A-phase and Y-phase / B-phase. For power system operations that require precise phase verification, this clear identification can greatly reduce misoperations caused by interface confusion, improving the accuracy and safety of work. Operators can directly select the corresponding phase output interface for connection according to needs without repeatedly confirming and comparing among multiple interfaces, thus improving work efficiency. Especially in emergency or high-voltage working environments, this design is particularly important.

[0027] The utility model provides a phase detector calibration device, which has the following beneficial effects:

[0028] The upper cover installed by hinges makes the opening and closing of the device simple and convenient, facilitating users to quickly access the calibration instrument body and its internal components. The design of the touch screen improves the user experience, making the operation more intuitive and fast.

[0029] The output interfaces (including X-phase / A-phase and Y-phase / B-phase output interfaces) are symmetrically distributed on both sides of the grounding interface. This layout is not only aesthetically pleasing but also convenient for users to perform wiring operations, reducing the possibility of incorrect connection.

[0030] The design of the first accommodation groove and the second accommodation groove effectively solves the problem of storing wiring tools such as cables, keeps the working area clean and orderly, and reduces the safety hazards and inconveniences caused by cable chaos.

[0031] The combination of the cooling fan and the cooling fins forms an efficient cooling system. The cooling fan extracts external air and makes it flow through the cooling fins, and finally discharges from the first accommodation groove. This process effectively reduces the working temperature of the calibration instrument body, ensures the long-term stable operation of the device, and extends its service life.

Detailed Embodiments

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0040] Please refer to Figures 1 to 3 as shown, the embodiments provided by the present utility model are as follows:

[0041] Embodiment 1

[0042] The phase detector calibration device includes a base 4. An upper cover 2 is rotatably installed on the base 4 through a hinge 1. A calibration instrument body 3 is installed inside the base 4. The calibration instrument body 3 is provided with a touch screen 304. On one side of the calibration instrument body 3 located at the touch screen 304, there are a grounding interface 301 and an output interface 302. There are two output interfaces 302 respectively, and the two output interfaces 302 are symmetrically distributed on both sides of the grounding interface 301. The symmetrically distributed output interfaces 302 make it more convenient and fast for users to connect external devices or cables. No matter from which direction the user approaches the device, they can easily find and connect the output interface 302 without adjusting the device position or rotating the interface direction. By symmetrically arranging the two output interfaces 302 on both sides of the grounding interface 301, the designer effectively utilizes the space of the device. This layout not only maintains the compactness of the device but also avoids interference and conflicts between the interfaces, improving the rationality of the overall layout. The grounding interface 301, as a key part of safety grounding, the choice of its position is crucial for the safety of the entire device. Setting the two output interfaces 302 at symmetric positions on both sides of the grounding interface 301 helps to ensure a good grounding state can be maintained simultaneously when connecting external devices, thus improving the safety performance of the device. One of the output interfaces 302 is an X-phase / A-phase output interface, and the other output interface 302 is a Y-phase / B-phase output interface. This design method directly clarifies the phase attributes of the two output interfaces 302, namely X-phase / A-phase and Y-phase / B-phase. For power system work that requires precise phase verification, this clear identification can greatly reduce misoperations caused by interface confusion, improving the accuracy and safety of work. Operators can directly select the corresponding phase output interface 302 for connection according to needs without repeatedly confirming and comparing among multiple interfaces, thus improving work efficiency. Especially in emergency or high-voltage working environments, this design is particularly important. On the calibration instrument body 3, a switch module 305 is installed on the side of the touch screen 304 facing away from the grounding interface 301. An emergency stop switch 306 is installed below the switch module 305 on the calibration instrument body 3.

[0043] Embodiment 2

[0044] For facilitating heat dissipation of the calibrator body 3 during its operation, exemplarily, such as Figures 1 to 3As shown in the figure, the present invention further includes: a first receiving groove 303 is provided above the touch screen 304 on the calibrator body 3, and a second receiving groove 307 is provided on the side of the calibrator body 3 away from the first receiving groove 303 with respect to the touch screen 304. The first receiving groove 303 and the second receiving groove 307 are used to store wiring tools such as cables used in the calibration. During the calibration process, various cables and wiring tools are often needed. If these tools are placed randomly, not only will they occupy a large amount of working space, but also the time for finding and retrieving tools will be increased. By storing the cables and wiring tools in the first receiving groove 303 and the second receiving groove 307, users can quickly find the required tools, thereby improving work efficiency. When the cables and wiring tools are not in use, if they are placed randomly or exposed to the external environment, they are easily damaged or contaminated. The design of the receiving grooves can effectively protect these tools from dust, moisture, and other potential hazards, extending their service life. At the same time, properly storing the cables and wiring tools can also reduce their accidental collisions and scratches on the calibrator body 3 or other devices, protecting the integrity and stability of the devices. Hollow plates 310 are provided at the bottom ends of both the first receiving groove 303 and the second receiving groove 307. There is a cavity between the bottom end of the base 4 and the calibrator body 3, and both the first receiving groove 303 and the second receiving groove 307 are connected to the cavity between the calibrator body 3 and the base 4 through the hollow plates 310. The cavity between the base 4 and the calibrator body 3, and the connection to the first receiving groove 303 and the second receiving groove 307 through the hollow plates 310 together form an efficient air circulation channel. This channel enables the cooling fan 309 to smoothly draw external cold air into the device, exchange heat through the heat dissipation fins 308, and then discharge the warm air, thereby achieving effective heat transfer and dissipation. Due to the existence of the air circulation channel, the working effect of the cooling fan 309 is significantly improved. The cold air can flow through the heat dissipation fins 308 more quickly, taking away more heat, and at the same time, the warm air can be discharged from the device more smoothly, avoiding heat accumulation. This efficient heat dissipation mechanism helps to reduce the working temperature of the calibrator body 3 and ensure the stable operation of the device. A cooling fan 309 is installed at the bottom end of the calibrator body 3 in the first receiving groove 303. The cooling fan 309 draws external air from the second receiving groove 307 into the cavity between the calibrator body 3 and the base 4. After the external air flows through the heat dissipation fins 308, it is discharged from the first receiving groove 303 through the cooling fan 309 to the base 4. This design enables the cooling fan 309 to directly introduce external cold air into the cavity between the calibrator body 3 and the base 4. These cold airs can quickly absorb and take away heat when flowing through the heat dissipation fins 308. Subsequently, the warm air is discharged from the first receiving groove 303 through the cooling fan 309, thus forming an efficient heat dissipation cycle. This design ensures that the calibrator body 3 can maintain a relatively low temperature during operation, preventing performance degradation or damage caused by overheating.By setting the second receiving groove 307 as the air inlet and the first receiving groove 303 as the air outlet, the designer has planned a clear and efficient air flow path for the cooling system. This design not only reduces the resistance of air flow but also improves the working efficiency of the cooling fan 309. At the same time, it also helps to ensure that the heat on the heat dissipation fins 308 can be evenly and quickly dissipated into the external environment. A heat dissipation fin 308 is installed between the bottom surface of the calibrator body 3 at the second receiving groove 307 and the first receiving groove 303. The calibrator body 3 is supported and installed in the base 4 through the heat dissipation fin 308. The heat dissipation fin 308 serves as an important medium for heat conduction and can effectively conduct the heat generated inside the calibrator body 3 to the external environment. By using the heat dissipation fin 308 to support and install the calibrator body 3, it can ensure that the heat can be quickly and evenly distributed on the fins, thereby increasing the heat dissipation area and improving the heat dissipation efficiency. Such a design is beneficial to reducing the working temperature of the calibrator body 3, avoiding performance degradation or damage caused by overheating, and ensuring the stability and reliability of the device under long-term and high-load working conditions. With the heat dissipation fin 308 as the support structure, the overall design of the device can be simplified, reducing additional support components and installation steps. This integrated design not only saves space but also makes the structure of the device more compact and beautiful. At the same time, the layout of the heat dissipation fin 308 can be optimized according to the requirements of heat conduction to ensure that the heat can flow along the predetermined path, further enhancing the heat dissipation effect.

[0045] Working principle:

[0046] The nuclear phase detector calibration device performs nuclear phase detection work through the calibrator body 3 inside it. The calibrator body 3 is provided with a touch screen 304, through which users can input commands, view detection results, etc. The device is provided with a grounding interface 301 and two output interfaces 302 (respectively the X-phase / A-phase and Y-phase / B-phase output interfaces 302) for connecting the nuclear phase detector or other related devices to be calibrated. The switch module 305 is used to control the power on and off of the device, while the emergency stop switch 306 provides a quick shutdown function in case of emergency. When performing nuclear phase detection, the user first sets the detection parameters through the touch screen 304, and then connects the nuclear phase detector or other devices to be calibrated to the calibrator body 3 through the output interface 302. The calibrator body 3 tests the device to be tested according to the preset detection program and parameters, and displays the test results on the touch screen 304.

[0047] When the cooling fan 309 is working, it sucks in external cold air from the opening of the second receiving groove 307, forming a negative pressure area. The sucked-in cold air flows through the heat dissipation fins 308 at the bottom of the calibrator body 3, exchanges heat with the heat on the fins, and takes away the heat on the fins. The warmed air after heat exchange is pushed by the cooling fan 309 and discharged outside the device from the opening of the first receiving groove 303, forming a complete air circulation. Through the above heat dissipation process, the phase detector calibration device can effectively reduce the working temperature of the calibrator body 3 and its internal components, ensuring the stability and reliability of the device under long-term and high-load working conditions. The combined design of the heat dissipation fins 308 and the cooling fan 309 improves the heat dissipation efficiency and reduces the risk of performance degradation or damage caused by overheating of the device.

[0048] The hollow plate 310 is designed at the bottom ends of the first receiving groove 303 and the second receiving groove 307, enabling the cavities between these two receiving grooves and the calibrator body 3 and the base 4 to communicate with each other. This design allows air to flow freely inside the device, forming an effective heat dissipation channel. When the cooling fan 309 is working, it sucks in external cold air from the opening of the second receiving groove 307. After these cold air passes through the heat dissipation fins 308 and exchanges heat with the heat on the fins, it becomes warmed air. The presence of the hollow plate 310 enables these warmed air to be smoothly discharged outside the device from the opening of the first receiving groove 303, thus improving the efficiency of the entire heat dissipation system. If there is no hollow plate 310 to connect the receiving grooves with the internal cavity, the cold air sucked in by the cooling fan 309 may accumulate in some areas and cannot be effectively discharged, resulting in heat accumulation in these areas. The design of the hollow plate 310 effectively avoids this situation and ensures that the heat can be evenly distributed and discharged in a timely manner.
