Description

Technical Field

[0001] The utility model relates to the technical field of electric power, in particular to a grounding wire group tester. Background Art

[0002] A grounding wire group tester is a device specifically used to test the performance of grounding wires in a power system. It is mainly used to detect and evaluate the resistance value of grounding wires or grounding systems to ensure that they meet safety standards and specifications. After a large number of searches, the publication number is CN215575432U, which discloses a grounding wire group tester. Through the design of connecting bushings, support vertical rods, sliding rods, threaded rods, and threaded locking grooves, this device has a supporting function, can raise the height of the tester body by one meter, so that the user does not need to squat down during operation, effectively avoiding the situation of physical damage to the user caused by long-term squatting operation, bringing convenience to the user's work, and improving the practicability of this device.

[0003] However, in the existing technology, when the tester is used for a long time, due to the large number of internal integrated electronic components and the relatively compact assembly structure, its heat dissipation performance is poor. At the same time, its main control switches are all in a exposed state, and it is very easy to accidentally touch them. Therefore, a grounding wire group tester is needed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a grounding wire group tester, which has the advantages of improving heat dissipation during work and avoiding accidental touch of the switch, and solves the problems that the tester has a compact structure, resulting in poor heat dissipation performance and easy accidental touch of the control switch during use.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A grounding wire group tester, including a box body, a tester main body is embedded in the box body, and a heat dissipation mechanism is arranged below the box body;

In the design, the cover body and the rear end of the bottom case are rotatably installed, ensuring the usability of the box body. A sealing ring is specially designed on the side opposite to the box body. This sealing ring not only enhances the sealing performance of the box body, preventing dust and moisture from invading, but also facilitates the user to easily open and close the cover body when needed for internal inspection or maintenance, thus improving the reliability of the device and the convenience of maintenance.

[0010] Preferably, support feet are fixedly installed at the four corners of the bottom of the bottom case. A handle is rotatably installed in the middle of the front of the bottom case.

The connecting pipe design on both sides of the outer wall of the intake fan cleverly connects the intake fan with the first intake hole, forming an efficient air flow path, ensuring that the heat inside the device can be quickly discharged, thus guaranteeing the stability and performance during long-term operation.

[0012] Preferably, a first power connection post and a second power connection post are embedded and installed in a rectangular array on one side of the upper end surface of the panel. A combination switch is embedded and installed at the front end of the other side of the upper end surface of the panel.

In the design, the design of the first air outlet of the bottom case and the design of the second air outlet of the protective case match each other and are connected and installed. This design not only ensures the smooth flow of the heat dissipation air flow, but also reduces the noise generated during air flow, improving the user experience. At the same time, the design of the first air inlets on both sides of the bottom case and the second air inlets on both sides of the protective case match, further improving the heat dissipation efficiency and ensuring that the device can maintain a good working state in various environments.
