How to conduct on-site commissioning of box-type transformers?

On-site commissioning of box-type transformers is a complex and meticulous process, which requires the commissioning personnel to have solid professional knowledge and rich practical experience. Through adequate preparation, meticulous commissioning and comprehensive records, the safe and reliable operation of the transformer can be effectively ensured, laying a solid foundation for the subsequent power supply.

Box-type substation commissioning Preliminary preparation

1. Read technical documents: The commissioning personnel should carefully read the equipment's instruction manual and related technical documents to understand the model, parameters and performance indicators of the transformer.

2. Check the on-site environment: Make sure there is no debris around the transformer and that it is well ventilated to avoid affecting the equipment. At the same time, ensure that the installation location is high and well drained, and avoid installing it in a low-lying area prone to water accumulation to prevent equipment damage due to flooding.

3. Prepare tools and instruments: Prepare the necessary tools and instruments, such as voltmeter, insulation resistance tester, variable frequency series resonant withstand voltage test device, transformer ratio tester, etc., so as to perform necessary tests during the commissioning process.

Box-type substation commissioning Debugging steps

1. Check the equipment status: Confirm that all equipment is in normal working condition without damage or abnormality.

2. Verify the protection function: Test the protection device of the box-type transformer to ensure that it can act in time when a fault occurs to protect equipment and personal safety.

3. Test the control system: Conduct a comprehensive test of the control system of the box-type transformer, including remote control, telemetry, telesignaling and other functions to ensure its accuracy and reliability.

4. Calibrate measuring equipment: Use standard instruments to calibrate the measuring equipment in the box-type transformer to ensure the accuracy of its measurement results.

5. Perform load testing: Under safe conditions, gradually increase the load, observe and record the operating status and data of the equipment to ensure that the equipment can operate stably under normal working load.

Finally, after the commissioning work is completed, we should write a detailed commissioning report to record the test results and problems found. This not only provides a reference for subsequent operation and maintenance, but also helps to improve the team's commissioning experience. In the report, it is recommended to summarize the difficulties and solutions encountered during the commissioning process for future improvements.

Box-type substation commissioning Precautions

1. Simplify the debugging steps: If you need to simplify the more complicated debugging steps, you can use debugging instruments to assist debugging. But necessary manual debugging is still required;

2. Debug according to the technical parameters of the box-type transformer: Debugging according to the technical requirements of the box-type transformer can avoid unnecessary failures;

3. Acceptance of debugging results: After completing the debugging, we need to conduct acceptance to ensure that all indicators of the box-type transformer meet the design requirements.

When debugging the box-type transformer, you need to be careful and serious to ensure that each link is correct and follow the standard operating procedures. At the same time, you also need to pay attention to relevant safety knowledge to ensure the safety of operators.
