Abstract
Description
Technical Field
[0001] This utility model belongs to the field of power detection technology, specifically relating to a grounding copper busbar resistance detection and leakage warning device. Background Technology
[0002] In high-voltage power laboratories, the grounding system is of paramount importance. However, the exposed grounding copper busbars currently lack grounding resistance detection and leakage warning mechanisms. The lack of grounding resistance detection means that when the grounding resistance increases, equipment leakage can easily lead to an increase in the outer casing voltage, posing a risk of electric shock to personnel who touch it. Without a leakage warning mechanism, leakage is difficult to detect in time, further increasing the risk of electric shock. When unreliable or loose grounding occurs, staff cannot know the situation in time. If operations are performed under these circumstances, there is a significant safety risk. During fault diagnosis, staff find it difficult to locate the root cause of the problem in a timely manner, which is time-consuming, labor-intensive, and can easily lead to the expansion of the fault, reducing work efficiency. Utility Model Content

This device can monitor the status of the grounding copper busbar in real time, acquire data through voltage and current sensors, and provide continuous resistance data and leakage information. The resistance calculation module calculates the grounding resistance, and the leakage judgment module determines whether leakage has occurred. When leakage is detected, an audible and visual alarm will immediately emit an audible and visual signal to remind staff to take timely measures to resolve the leakage problem and reduce the risk of electric shock.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A grounding copper busbar resistance detection and leakage warning device mainly includes a tester body, a control board, a battery, a display screen, an audible and visual alarm, a connecting wire, a ground wire, a voltage sensor, and a current sensor.

The display screen and the audible and visual alarm are located on the outer surface of the tester body. One end of the connecting wire used to transmit voltage signals is connected to the grounding copper busbar, and the other end is connected to the detection interface. One end of the ground wire is connected to the ground wire interface, and the other end is grounded. The voltage sensor and the current sensor are installed on the grounding copper busbar. The battery, display screen, audible and visual alarm, voltage sensor, and current sensor are electrically connected to the control board.
[0005] The main body of the tester is made of high-strength, high-insulation nylon composite material.
[0006] The display screen is a touch screen.
[0007] The control board also integrates a wireless communication module that can synchronize real-time data to a remote monitoring platform.
[0008] The beneficial effects of this utility model are:
[0009] This device can monitor the status of the grounding copper busbar in real time. It acquires data through voltage and current sensors, providing continuous resistance data and leakage information.

The device mainly includes a tester body 1, a control board 2, a battery 3, a display screen 4, an audible and visual alarm 5, a connecting line 6, a ground wire 7, a voltage sensor 8, and a current sensor 9. The tester body 1 has a hollow internal structure, and its outer surface is equipped with a power switch 11, a detection interface 12, a ground wire interface 13, and function buttons 14. The control board 2 is installed inside the tester body 1 and integrates a resistance calculation module and a leakage judgment module. The battery 3 is installed inside the tester body 1. The display screen 4 and the audible and visual alarm 5 are located on the outer surface of the tester body 1. One end of the connecting line 6, used for transmitting voltage signals, is connected to the grounding copper busbar 10, and the other end is connected to the detection interface 12. One end of the ground wire 7 is connected to the ground wire interface 13, and the other end is grounded. The voltage sensor 8 and the current sensor 9 are installed on the grounding copper busbar 10. The battery 3, the display screen 4, the audible and visual alarm 5, the voltage sensor 8, and the current sensor 9 are electrically connected to the control board 2.
[0016] The main body 1 of the test instrument is made of high-strength, high-insulation nylon composite material, ensuring safety and stability when used in a high-voltage power laboratory environment.
[0017] The display screen 4 is a touch screen; the touch screen design makes operation simpler and more intuitive, and facilitates data analysis and management by staff.
[0018] The control board 2 also integrates a wireless communication module that can synchronize real-time data to a remote monitoring platform; it provides remote monitoring functionality, further improving work efficiency and security.
[0019] Work process:
[0020] Connect one end of the connecting wire 6 to the grounding copper busbar 10 and the other end to the detection interface 12 of the tester body 1. Connect one end of the ground wire 7 to the grounding interface 13 and the other end to the ground. Press the power switch 11 to start the tester body 1. The battery 3 starts to power the entire device, and the device enters the working state. The voltage sensor 8 and current sensor 9 installed on the grounding copper busbar 10 start to work. The voltage sensor 8 collects the voltage signal of the grounding copper busbar 10 in real time, and the current sensor 9 collects the current signal of the grounding copper busbar 10 in real time. The connecting wire 6, used to transmit the voltage signal, transmits the voltage signal collected by the voltage sensor 8 to the detection interface 12 of the tester body 1. The detection interface 12 transmits the received voltage and current signals to the control board 2 installed in the tester body 1. The resistance calculation module in the control board 2 calculates the grounding resistance value of the grounding copper busbar 10 according to Ohm's law based on the collected voltage and current data. At the same time, the leakage current detection module determines whether there is leakage current based on the voltage and current data. The control board 2 transmits the calculated grounding resistance value to the control board 2. The resistance value and leakage current detection data are transmitted to the display screen 4 on the outer surface of the main body 1 of the tester for display. Staff can easily view the current grounding resistance value, historical data, resistance change trends, and other information. They can also manually set alarm thresholds according to actual needs. If the grounding resistance value exceeds the alarm threshold set by the staff, or if the leakage current detection module detects a leakage current, the control board 2 will control the audible and visual alarm 5 to emit an audible and visual signal to remind staff to handle the situation promptly. Staff can quickly locate the root cause of the problem based on the alarm information and conduct timely troubleshooting and repair. This device can remain connected to the grounding copper busbar without being removed. By using this device, abnormal grounding resistance and leakage current can be detected in a timely manner, ensuring staff safety, improving the efficiency of troubleshooting, and ensuring the normal operation of the high-voltage power laboratory. The wireless communication module integrated into the control board 2 synchronizes real-time data such as grounding resistance and leakage current to the remote monitoring platform, enabling remote management personnel to understand the status of the grounding copper busbar 10 in a timely manner, achieving remote monitoring and management.
