When the transformer trips automatically, it is necessary to first confirm the cause and condition of the trip before proceeding with the treatment. The following are some common methods and steps for handling automatic tripping of transformers:
① Confirm the cause of the trip: Check the circuit and equipment to determine the cause of the trip. Possible causes include overcurrent, short circuit, overload, abnormal voltage, etc.
② Power outage: Before proceeding with subsequent processing, it is important to ensure safety and cut off the power supply to avoid the risk of electric shock.
③ Inspection equipment: Check transformers and corresponding electrical equipment, such as fuses, fuses, etc. If the equipment is found to be burnt, loose, or damaged, it needs to be replaced or repaired.
④ Reset protection equipment: Partial automatic tripping is caused by a malfunction of the protection equipment. Reset or adjust the parameters and settings of the protection equipment to ensure its normal operation.
⑤ Check the circuit: Check the input and output circuits of the transformer to ensure proper wiring. Check the cables or insulation materials for damage, short circuits, or breakage, and repair or replace the cables that require repair.
⑥ Check load: Check the load condition of the transformer and confirm if the load is too large, causing overload tripping. Determine whether to adjust or redistribute the load based on the load situation.
⑦ Check for environmental factors: There may be some environmental factors that may cause the transformer to trip, such as overload, exceeding the rated temperature, etc. Ensure good ventilation and moderate temperature around the transformer.
⑧ System stability recovery: After inspecting and troubleshooting transformers and electrical equipment, gradually restore the power supply, check the stability of the system, and ensure that no other faults occur.
It should be noted that for the handling of transformer automatic tripping, if you do not have relevant power professional knowledge and experience, it is recommended to seek the help of power operation and maintenance personnel or professional technical personnel to ensure safety and effective problem-solving.
