What problems should be paid attention to in the inspection of substation equipment?

Substation equipment inspection is an important part of ensuring the normal operation, safety and reliability of equipment. The following are the key issues to pay attention to when conducting equipment inspection:
Step 1 Security check

1.1 Equipment appearance inspection: Check the appearance of the equipment, including any damage, corrosion, oil leakage, loosening, etc.

1.2 Safety sign inspection: Check whether the safety signs and warning signs are clearly visible to ensure that the safety warning work is effective.

1.3 Safety inspection: Ensure that safety devices are in good condition, such as fences, protective covers, etc., to prevent personnel from mishandling or accidental injury.

2. Electrical parameter check

2.1 Electrical connection inspection: Check whether the wiring is loose, corroded or burned to ensure that the connection is firm.

2.2 Electrical parameter measurement: Use appropriate tools to measure electrical parameters, including voltage, current, insulation resistance, etc.

2.3 Line inspection: Check the status of cables, lines, and conductors to detect possible damage or aging problems.


3. Equipment operation status check

3.1 Temperature and vibration: Pay attention to the temperature and vibration of the equipment. Abnormal conditions may suggest problems with the operation of the equipment.

3.2 Abnormal sound: Auditory inspection of whether there is any abnormal sound during the operation of the equipment, such as noise, abnormal sound, etc.

3.3 Lubrication: Check the lubrication of the equipment to ensure the normal operation of the lubricated parts.
4. Environmental and pollution inspections

4.1 Cleanliness: Check whether the surrounding environment of the equipment is clean to prevent the accumulation of debris from affecting the operation of the equipment.

4.2 Pollution investigation: Check the surface of the equipment for contaminants and clean it up in time to maintain the cleanliness of the equipment surface.
5. Recording and reporting

5.1 Inspection records: Record the inspection time, content, and problems found, and establish inspection records for follow-up tracking and analysis.

5.2 Abnormal report: For any abnormal situation found, report it to the supervisor or maintenance personnel in a timely manner and initiate corresponding maintenance measures.
conclusion

Substation equipment inspection is an important means to ensure the safe and reliable operation of equipment. Through regular inspections, potential problems can be found and eliminated, equipment failures can be prevented, and the normal operation of the substation can be ensured. During the inspection process, attention should be paid to safety, strict implementation of operating procedures, and timely recording and reporting of abnormal conditions to ensure the long-term stable operation of substation equipment.
