To use the microcomputer relay protection tester correctly, it is necessary to follow a series of operating steps and precautions to ensure the accuracy of the test and the safety of the equipment. Here is a detailed guide:
1. Preparation before use
① Power connection:
Insert the power cord of the microcomputer relay protection tester into an AC220V power socket and confirm that the socket is grounded to prevent electric shock and equipment damage.
Attention: The tester is prohibited from connecting to AC380V or other non specified power sources to avoid damaging the equipment.
② Equipment inspection:
Check if the wiring of the tester is correct and ensure that all interfaces are not loose or short circuited.
Check if the ventilation port of the tester is unobstructed to avoid overheating of the equipment due to poor heat dissipation during the testing process.
③ Grounding treatment:
To prevent static induction and equipment damage, the grounding wire socket of the tester should be reliably grounded before the test.
2. Operation steps
① Start device:
Turn on the power switch of the tester, start the industrial computer, and wait for the Windows operating system to fully start.
Enter the main interface of the tester software and select the corresponding testing module according to the testing requirements.
② Wiring and configuration:
According to the test content, connect the voltage, current, and input/output wiring. Please note that the voltage circuit should not be short circuited, and the current circuit should not be open circuited.
Select appropriate testing parameters, such as fault type, fault location, voltage and current magnitude, and make corresponding settings.
③ Start testing:
Turn on the power switch of the amplifier and follow the operating steps of the tester to perform the corresponding settings and operations.
Monitor the display screen and indicator lights of the testing device to ensure a smooth testing process.
④ Recording and analysis:
After the test is completed, the tester will automatically analyze the test data and generate a test report. Operators need to carefully record the test results and conduct necessary analysis.
⑤ Turn off the device:
First turn off the power switch of the amplifier, then turn off the software menu and host power of the tester.
Disconnect the relevant test connection wires and store the tester properly in the packaging box.
3. Precautions
① Safe operation:
During the testing process, attention should be paid to safe operation to avoid accidents such as electric shock and short circuit.
Do not directly turn off the power in the output state to avoid protection misoperation caused by output errors during shutdown.
② Heat dissipation and ventilation:
When conducting high current output tests, it is necessary to ensure that the instrument has sufficient heat dissipation time to avoid equipment overheating and damage.
Keep the air flow through the vent of the tester unobstructed and do not block the vent.
③ Equipment maintenance:
Regularly maintain and upkeep the testing equipment, including cleaning the equipment surface, checking wiring and interfaces, etc.
Be careful not to frequently turn on and off the power supply to avoid unnecessary damage to the equipment.
④ Software protection:
The computer equipped with the tester is installed with system protection software. Please do not save any personal files or perform illegal operations on the C drive.
If you need to store data, please save it on a D drive or other designated location.
⑤ Exception handling:
If any abnormal situations are encountered during the testing process (such as interface data errors, device disconnection, etc.), the power should be cut off in a timely manner and the manufacturer should be contacted for handling. Do not disassemble or repair the equipment on your own to avoid causing greater damage.
By following the above steps and precautions, the correct use of the microcomputer relay protection tester and the safety of the equipment can be ensured.
