Transformer repair process

Quanganhcons applies an in-depth transformer repair process, from inspection to post-repair maintenance. Every material and device has a clear quality certification. The company focuses on the origin of materials to ensure electrical stability and quality after repair.

The transformer repair process plays a key role in ensuring the efficiency and longevity of the machine. To conduct effective repairs, this process is divided and implemented at specialized levels:

1. Repair level categorization:

• Minor repair: Perform small-scale repairs like inspecting the outside of the machine without oil removal or core opening. Tasks include cleaning and inspection, aiming to maintain the basic operating efficiency of transformers without prolonged device shutdown.
• Periodic major repair: Requires complete extraction of the core or the entire machine for comprehensive inspection. Tasks include drying the windings and other components to ensure stable operation.
• Restorative major repair: When needing to restore severely damaged transformers, tasks include renewing the windings, repairing the transformer core and restoring machine insulation.

1. Typical minor repair steps:

• Inspect the transformer exterior and perform minor repairs if necessary.
• Clean the housing, handle oil bushings, remove sludge from auxiliary oil tanks, and check oil level gauges.
• Replace silica gel in siphon tanks to protect against humidity.
• Inspect, tighten valves, gaskets, and lightning protection.
• Maintain cooling systems and necessary components.

1. Periodic maintenance and inspection process:

• Inspect voltage, load mode, and operating temperature of the transformer.
• Take oil samples for analysis, ensuring quality, and detecting abnormal humidity.
• Inspect and clean components such as bushing gaskets and terminals.
• Maintain and paint insulation to ensure system operation pressure.
• For dry transformers, special attention to dust cleaning and moisture removal is required.

1. Additional tasks in major repair or deep maintenance:

• Dismantle and repair or replace windings based on damage level.
• Repair or replace transformer cores, as well as restore insulation in necessary lamination.
• Clean the entire station, inspect and tighten sockets and cable joints.
• Inspect and maintain control devices and related measuring equipment.

1. Safety and technical requirements:

• Ensure the transformer is completely de-energized, grounded, and all cutting devices are locked before repair.
• All complex joint repairs must be performed by highly skilled workers and follow strict technical procedures.
• Detailed logging of operating parameters and inspection results to ensure logistics tracking and analysis.
