Description

Technical Field

[0001] This utility model relates to the field of electrical testing technology, and in particular to an auxiliary device for testing the insulation of electrical circuits. Background Technology

[0002] With the deepening of smart grid construction, the insulation condition of electrical lines is directly related to the safe and stable operation of the power supply system. Traditional insulation testing devices typically employ live-line testing technology, judging the insulation degradation by real-time monitoring parameters such as leakage current and dielectric loss. However, under high-load and long-term operating conditions, such devices face the following technical bottleneck: the internal power devices (such as high-frequency power modules and signal amplification circuits) continuously generate heat, leading to a sharp increase in the temperature of core components.

[0003] Chinese patent CN218213120U discloses an auxiliary device for electrical circuit insulation testing. By setting heat dissipation grooves, heat dissipation inside the device housing is facilitated. A second filter can reduce impurities from entering the device housing through the heat dissipation grooves. When the temperature sensor detects that the temperature inside the device housing is higher than a set value, the controller controls the fan to run, which helps to improve heat dissipation inside the device housing.

[0004] However, the above-mentioned heat dissipation methods are fixed, meaning that no matter how high the temperature inside the casing is, only a single heat dissipation method can achieve limited heat dissipation. If the heat dissipation is not good, it may cause the component temperature to be too high, affecting the detection accuracy, shortening the component life, or even causing the device to malfunction. Therefore, the present invention solves the shortcomings of the above-mentioned technical problems. Utility Model Content

[0005] Based on the aforementioned technical problems, this utility model proposes an auxiliary device for electrical circuit insulation testing.

[0006] This utility model proposes an auxiliary device for electrical circuit insulation testing, including a testing device housing, a testing element installed inside the testing device housing, and a heat dissipation mechanism provided inside the testing device housing. The heat dissipation mechanism includes a heat-conducting plate, which dissipates the heat generated by the testing element during operation.

[0007] Preferably, the heat-conducting plate is a copper-aluminum explosion-bonded composite laminate, wherein the copper layer is bonded to the detection element.

[0008] Through the above technical solution, in order to improve the heat dissipation performance of the detection device, the composite structure of the heat-conducting plate achieves rapid and uniform heat distribution in the copper layer, reducing local hot spots in the detection element, while the aluminum layer reduces weight and expands the application range of the detection device.

[0009] Preferably, the heat dissipation mechanism further includes heat dissipation fins fixedly connected to one side surface of the heat-conducting plate, the heat dissipation fins being anodized aluminum alloy, and the aluminum layer of the heat-conducting plate connecting the heat dissipation fins.

[0010] Through the above technical solution, the heat dissipation fins are made of anodized aluminum alloy, which has the characteristics of forming a dense oxide film on the aluminum surface, enhancing corrosion resistance and wear resistance, while improving the oxidation resistance of the heat dissipation fins. The aluminum alloy fins have a high thermal conductivity, and the fin structure increases the heat dissipation area, accelerating the heat exchange with air convection.

[0011] Preferably, the heat dissipation mechanism further includes a coil inserted through the surface of the heat dissipation fins, the inlet and outlet ends of the coil extending to the outside of the housing of the detection device.

[0012] With the above technical solution, when the temperature of the detection element is too high and needs to be dissipated quickly, in order to enhance heat exchange, a coil with fixed interlacing is set on the surface of the heat dissipation fins, and the coil is made of aluminum oxide. In this way, by circulating the cooling medium in the coil, the heat absorbed by the fins can be transferred to the outside of the device more quickly and efficiently.

[0013] Preferably, a temperature sensor is installed on the inner wall of the housing of the detection device.

[0014] In order to dynamically adjust the heat dissipation intensity, i.e. control the flow of cooling medium in the coil, the temperature inside the detection device housing is detected in real time by a temperature sensor, and then it is determined whether the cooling medium needs to be activated for heat dissipation.

[0015] Preferably, a heat dissipation window is provided through one side surface of the housing of the detection device.

[0016] In order to enhance the heat exchange between the heat dissipation fins and the external environment, the above technical solution promotes the natural convection of air inside and outside the casing through the heat dissipation window.

[0017] Preferably, a louvered heat dissipation window is fixedly installed on the inner surface of the heat dissipation window.

[0018] Through the above technical solution, in order to dynamically adjust the heat dissipation intensity and avoid dust blockage affecting heat dissipation efficiency, the airflow through the heat dissipation window can be dynamically adjusted by controlling the opening angle of the louvered heat dissipation window blades, thereby precisely controlling the heat dissipation intensity of natural convection. At the same time, the blades of the louvered heat dissipation window are set at an angle, so that most of the dust is blocked from entering. In the future, a filter screen can also be added to the outside of the louvered heat dissipation window to further filter the dust.

[0019] The beneficial effects of this utility model are as follows: By incorporating a heat dissipation mechanism, dynamic heat dissipation can be achieved inside the detection device housing. During adjustment, a heat-conducting plate made of copper and aluminum explosion-proof composite laminate allows the copper layer to heat up quickly and evenly, reducing local hot spots. The aluminum layer reduces weight and expands its application range. Coils are inserted into the surface of the heat dissipation fins, and a temperature sensor monitors the internal temperature of the device in real time. The flow of the cooling medium in the coils is dynamically adjusted according to temperature changes, achieving intelligent heat dissipation. Furthermore, by controlling the opening and closing angle of the louvered heat dissipation windows, the airflow through the heat dissipation windows can be dynamically adjusted, thereby precisely controlling the intensity of natural convection heat dissipation. Through the above design, the device can dynamically adjust the heat dissipation intensity according to internal temperature changes, achieving intelligent heat dissipation, effectively reducing component temperature, improving detection accuracy and device lifespan, and ensuring the safe and stable operation of electrical circuits.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-3 An auxiliary device for electrical circuit insulation testing includes a testing device housing 1, a testing element 2 installed inside the testing device housing 1, and a heat dissipation mechanism inside the testing device housing 1, which includes a heat-conducting plate 3 to dissipate the heat generated by the testing element 2 during operation.

[0024] To improve the heat dissipation performance of the detection device, the heat-conducting plate 3 is a copper-aluminum explosion-laminated composite laminate, in which the copper layer is bonded to the detection element 2. The composite structure of the heat-conducting plate 3 enables the copper layer to heat up quickly and evenly, reducing local hot spots on the detection element 2, while the aluminum layer reduces weight and expands the application range of the detection device.

[0025] The heat dissipation mechanism also includes heat dissipation fins 4 fixedly connected to one side surface of the heat-conducting plate 3. The heat dissipation fins 4 are made of anodized aluminum alloy. The aluminum layer of the heat-conducting plate 3 is connected to the heat dissipation fins 4. The heat dissipation fins 4 are made of anodized aluminum alloy. Its features include the formation of a dense oxide film on the aluminum surface, which enhances corrosion resistance and wear resistance, while improving the oxidation resistance of the heat dissipation fins 4. The aluminum alloy fins have a high thermal conductivity, and the fin structure increases the heat dissipation area, accelerating the heat exchange with air convection.

[0026] When the temperature of the detection element 2 is too high and rapid heat dissipation is required, in order to enhance heat exchange, the heat dissipation mechanism also includes a coil 5 inserted through the surface of the heat dissipation fins 4. The inlet and outlet ends of the coil 5 extend to the outside of the detection device housing 1. The coil 5 is fixedly inserted on the surface of the heat dissipation fins 4, and the coil 5 is made of aluminum oxide. Thus, by circulating the cooling medium in the coil 5, the heat absorbed by the fins can be transferred to the outside of the device more quickly and efficiently.

[0027] In order to dynamically adjust the heat dissipation intensity, that is, to control the flow of cooling medium in coil 5, a temperature sensor 6 is installed on the inner wall of the detection device housing 1. To control the flow of cooling medium in coil 5, the temperature inside the detection device housing 1 is detected in real time by the temperature sensor 6, and then it is determined whether the cooling medium needs to be activated for heat dissipation.

[0028] In order to enhance the heat exchange between the heat dissipation fins 4 and the external environment, a heat dissipation window 7 is provided through one side surface of the detection device housing 1 to promote natural convection of air inside and outside the housing.

[0029] In order to dynamically adjust the heat dissipation intensity and avoid dust blockage affecting heat dissipation efficiency, a louvered heat dissipation window 8 is fixedly installed on the inner surface of the heat dissipation window 7. By controlling the opening and closing angle of the louvered heat dissipation window 8, the airflow through the heat dissipation window 7 can be dynamically adjusted, thereby precisely controlling the heat dissipation intensity of natural convection. At the same time, the louvered heat dissipation window 8 is set at an angle, thus blocking most of the dust from entering. In the future, a filter screen can also be added to the outside of the louvered heat dissipation window 8 to further filter the dust.

[0030] By setting up a heat dissipation mechanism, dynamic heat dissipation can be achieved inside the housing 1 of the detection device. During the adjustment process, the heat-conducting plate 3, which uses a copper-aluminum explosion-laminated composite laminate, can quickly and evenly heat the copper layer, reducing local hot spots. The aluminum layer reduces weight and expands the application range. Coils 5 are inserted on the surface of the heat dissipation fins 4. The internal temperature of the device is monitored in real time by a temperature sensor 6. The flow of the cooling medium in the coil 5 is dynamically adjusted according to the temperature change to achieve intelligent heat dissipation. Then, by controlling the opening and closing angle of the louvered heat dissipation window 8, the airflow through the heat dissipation window 7 can be dynamically adjusted, thereby precisely controlling the heat dissipation intensity of natural convection. Through the above design, the device can dynamically adjust the heat dissipation intensity according to the internal temperature change, achieve intelligent heat dissipation, effectively reduce the component temperature, improve detection accuracy and device life, and ensure the safe and stable operation of the electrical circuit.

[0031] Working principle: In a specific embodiment of this invention, the detection element 2 generates heat during operation. The composite heat-conducting plate 3 quickly and evenly conducts the heat generated by the detection element 2, avoiding local overheating. The heat dissipation fins 4 increase the heat dissipation area, promote heat exchange with air convection, and accelerate heat dissipation. When the temperature sensor 6 detects that the internal temperature of the device is too high, the cooling medium in the coil 5 begins to circulate, transferring the heat to the outside of the device more quickly. The heat dissipation window 7 and the louvered heat dissipation window 8 promote natural convection of air inside and outside the casing, further enhancing the heat dissipation effect.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
