As a professional service provider in the field of power transmission and distribution, Kechang Electric knows that power transformers are the core equipment of the power transmission and distribution system, and they are responsible for the important tasks of voltage conversion and power transmission. Its stable operation is essential to the safety and efficiency of the entire power grid. Based on years of practical experience in the research and development, production and operation and maintenance of power equipment, Kechang Electric adheres to the concept of scientific and standardized maintenance, not only to help customers extend the service life of transformers, reduce the risk of failure, but also to ensure the continuous and reliable supply of electricity. This article combines the latest industry standards and Kechang Electric's operation and maintenance service experience to summarize the main points of power transformer maintenance and provide professional reference for the industry and customers.
1. Routine inspection and monitoring are the basis of maintenance work
It is also one of the core links of Kechang Electric's operation and maintenance services. Kechang Electric recommends that under normal working conditions, remote monitoring is required at least once a day, on-site inspections are required once a week, and special inspections are required after abnormal weather such as thunderstorms and high temperatures. Focus on checking online monitoring data such as oil level, oil temperature, cooling system, casing appearance, grounding device and dissolved gas analysis, and record abnormal phenomena such as abnormal noise, oil leakage, and casing discoloration in a timely manner, and the professional and technical personnel of Kechang Electric will respond quickly and deal with it in a timely manner, resolutely preventing the expansion of minor faults.
2. The maintenance of insulating oil is particularly critica.
It is also the key direction of Kechang Electric's operation and maintenance services.Insulating oil assumes the roles of insulation, cooling, and arc extinguishing, and its quality directly affects the safety of transformer operation.Kechang Electric strictly complies with the GB/T 14542-2017 standard to provide customers with professional insulating oil testing, purification and replacement services, comprehensive testing of breakdown voltage, moisture content, acid value and other key indicators, and timely treatment of oils that do not meet the standards. At the same time, combined with Kechang Electric's accumulation in transformer sealing technology, it reminds customers to pay attention to the sealing of equipment, prevent moisture from entering and affecting the insulation performance, and avoid safety hazards from the source.
3. The maintenance of key components cannot be ignored.
Kechang Electric relies on its mature technical strength to provide customers with full-process component maintenance support.In terms of cooling systems, Kechang Electric's professional team regularly conducts inspections for customers to ensure the normal operation of radiators and fans to avoid overheating of equipment due to poor heat dissipation; in strict accordance with industry standards and Kechang Electric operation and maintenance specifications, control the temperature of the transformer to ensure that the oil temperature in the natural circulation does not exceed 95℃, the forced oil circulation does not exceed 85℃, and the temperature of the class A insulated winding does not exceed 105℃; For tap switches, Kechang Electric provides regular inspection, commissioning and maintenance services to ensure flexible switching, good contact, and effective prevention of poor contact, overheating and other failures.
4. Establish a comprehensive maintenance system and emergency response plan
AFinally, Kechang Electric recommends that customers establish a sound maintenance system and emergency plan, while relying on their own professional capabilities to provide comprehensive support. Kechang Electric regularly conducts professional training for customer maintenance personnel to ensure that they are familiar with operating specifications and fault handling methods; for typical faults such as light gas alarms and heavy gas tripping, combined with Kechang Electric's many years of fault handling experience, it is clear that light gas alarms need to be analyzed within 24 hours, and forced power transmission is prohibited before the cause of heavy gas tripping is identified; at the same time, Kechang Electric can assist customers to entrust third-party institutions to conduct annual energy efficiency and insulation status assessments to ensure that the equipment meets the operating requirements of GB 20052-2020, and the safe and stable operation of the equipment is guaranteed in all directions.
The scientific maintenance of power transformers is a system project. Kechang Electric always adheres to the service concept of "professional empowerment and full escort", and deeply combines routine inspections, maintenance of key components, and standardized management with its own technical advantages. In the future, Kechang Electric will continue to deepen the field of power operation and maintenance, adhere to prevention as the main focus, integrate preventive maintenance and predictive maintenance, and provide customers with more efficient and professional operation and maintenance services to help transformers operate stably and escort the safe and efficient operation of the power grid.
