[0026] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, an embodiment of the utility model provides a relay protection device for a relay protection tester, including a storage portion 1, one side of the storage portion 1 is a flat surface for easy installation against a wall, and the other side is an arc surface to reduce electromagnetic interference and provide better heat dissipation effect; a wiring portion 8, which is detachably mounted on the storage portion 1, and the wiring portion 8 includes a hub 801; a limit member 802, which is detachably mounted on the storage portion 1, and a channel is provided on the limit member 802; an anti-collision member 803, which is detachably mounted on the storage portion 1, and the length of the anti-collision member 803 is greater than the length of the limit member 802.

[0027] Hub 801 is responsible for integrating wires from different modules inside the relay protection device and uniformly managing the entry and exit of wires, which helps to reduce wire confusion, improve the neatness inside the device and the stability of signal transmission.

[0028] The limiter 802 is used to fix and limit the position of the wires to prevent the wires from moving or loosening inside the device, while keeping the wires arranged along a predetermined path, increasing the organization and aesthetics inside the device, allowing the wires to pass smoothly, and also protecting the wires from damage caused by squeezing or friction.

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the support portion 12 is slidably mounted on the storage portion 1 via a sliding member 13 , and a through hole is provided on the support portion 12 .

[0030] The support portion 12 can slide on the storage portion 1, so that the position of the support portion 12 can be adjusted as needed, which simplifies the wiring process and helps the air circulation inside the device, improving the heat dissipation efficiency, which is crucial to improving the life and performance stability of the electronic components inside the device, so that it can adapt to different installation environments and usage requirements. When the device needs to be maintained or upgraded, the staff can easily move the support portion 12 through the sliding member 13, so as to quickly access the components located under or inside the support portion 12, thereby improving the efficiency of maintenance and upgrades.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a vent 11 is provided on the storage portion 1 ; and a filter 10 is detachably mounted on the vent 11 .

[0032] The vent 11 allows external air to flow into the interior of the device, which is essential for maintaining a suitable operating temperature for the internal electronic components. Good ventilation can effectively dissipate heat and prevent overheating, thereby extending the service life of the device. In addition, the vent 11 can also provide a certain natural ventilation effect, which helps to keep the internal environment of the device dry and reduce the potential damage of moisture to electronic components.

[0033] The filter 10 is detachable for easy regular cleaning or replacement. The main function of the filter 10 is to filter dust, particulate matter and other potential pollutants in the air entering the device, thereby preventing these substances from accumulating on electronic components, which may cause malfunctions or performance degradation.

[0035] Fan 9 provides a means of active heat dissipation, which accelerates the discharge of internal hot air and the intake of external cold air through forced convection, effectively reducing the operating temperature of electronic components inside the device, helping to even out the temperature distribution inside the device, avoiding the generation of local hot spots, and ensuring that all electronic components can work stably within the ideal temperature range. When the device is working for a long time or in a closed environment, the heat dissipation effect of fan 9 can slow down the rise of internal temperature and extend the safe operation time of the equipment in a high temperature environment. Continuous and effective heat dissipation helps to maintain the performance and stability of electronic components, thereby extending the service life of the entire relay protection device and improving the reliability and continuity of the entire relay protection device.

[0037] The mounting member 2 provides additional support and fixing points, so that other equipment or accessories can be easily installed, and the device can be mounted on a wall, increasing the versatility and customizability of the device.

[0038] The support feet 7 ensure that the device is stably placed on the ground to prevent shaking or tilting, which is very important for maintaining the correct positioning and operation of the device and protecting the bottom of the device from possible damage caused by direct contact with the ground, such as wear, scratches or other forms of physical damage.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the sealing door 5 is sealingly installed on the storage portion 1; and the observation window 6 is opened on the sealing door 5.

[0040] The sealed door 5 provides protection for the interior of the device, preventing dust, moisture and other contaminants from entering the interior of the device, ensuring that the electronic components operate in a clean and dry environment. When the device needs to be closed for transportation or used in a harsh environment, the sealed door 5 can provide additional security, enhance the device's anti-interference ability, and reduce the impact of external electromagnetic interference on device performance.

[0041] The observation window 6 allows the user to directly observe the internal state of the equipment without opening the sealing door 5, so as to quickly understand the operation status of the equipment and reduce the maintenance work caused by frequent opening of the sealing door 5. At the same time, it reduces the impact of environmental changes on the inside of the equipment. The observation window 6 is usually designed to be a transparent material, which not only provides the convenience of visual monitoring, but also maintains the protective function of the sealing door 5.

[0042] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the interface 3 is opened on the storage portion 1; and the controller 4 is arranged on the storage portion 1.

[0043] The interface 3 and the controller 4 together ensure that the relay protection device can correctly communicate with the outside world and provide effective protection for the power system. With the development of technology.

[0044] The technical solution provided by the utility model is that when in use, each component is placed on the support part 12, and the cable is inserted into the hub 801 through the channel on the limiter 802. When the component needs to be replaced or repaired, the support part 12 can be pulled out.

[0045] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention.
