Tagalog The grounding resistance value of the bending machine can be tested using a dedicated grounding resistance tester. The following are the general testing steps:
1. Choose a suitable grounding resistance tester: Ensure that the grounding resistance tester used is calibrated and suitable for the type of equipment to be measured and the range of grounding resistance.
2. Prepare measurement tools: In addition to the grounding resistance tester, auxiliary tools such as test wires and grounding clamps need to be prepared.
3. Disconnect power and air sources: Before conducting grounding resistance measurements, ensure that the power and air sources of the bending machine have been disconnected to avoid the influence of current on the measurement results.
4. Connect the test wire: Connect the test wire of the grounding resistance tester to the grounding body of the bending machine. According to the instructions of the testing instrument, correctly connect the testing wire and grounding clip.
5. Conduct measurement: Follow the instructions of the grounding resistance tester, set up the testing instrument, and start the measurement program. Wait for the testing instrument to stabilize and record the measurement results.
6. Analyze measurement results: Based on the measurement results, determine whether the grounding resistance value of the bending machine meets safety standards and equipment requirements. Generally speaking, the grounding resistance value should be less than or equal to the specified limit value.
7. Precautions:
a. When measuring grounding resistance, interference from other electrical equipment should be avoided to ensure the accuracy of the test results.
b. If the measurement results do not meet the requirements, the grounding body, grounding wire, and connections should be checked for looseness, damage, or other faults, and repaired in a timely manner.
c. Regularly measure the grounding resistance to ensure the safety and reliability of the grounding system.
In summary, using a dedicated grounding resistance tester to measure the grounding resistance is an important means to ensure good grounding of the bending machine. By using the correct measurement methods and precautions, it is possible to accurately determine whether the grounding resistance value of the bending machine meets safety standards and equipment requirements.
