Transformer Types
Transformers can be classified into different types based on their structure, purpose, and operating principles. Some common types of transformers include:
Dry-Type Transformer: A dry-type transformer is a transformer that does not use insulating oil but instead utilizes dry insulation materials. They are typically used in indoor environments and have good environmental and safety characteristics.
Oil-Immersed Transformer: An oil-immersed transformer is a transformer that uses insulating oil for insulation and heat dissipation. They are widely used in power systems and have good heat dissipation and electrical insulation properties.
Dry-Type Power Transformer: A dry-type power transformer is a type of transformer used in power systems, typically for medium-sized substations and industrial applications.
Oil-Immersed Power Transformer: An oil-immersed power transformer is an oil-immersed transformer used in power systems, suitable for various scales of power systems and power generation facilities.
Autotransformer: An autotransformer is a special type of transformer where a portion of the winding serves as both the primary and secondary winding. They are commonly used for voltage regulation, isolation, and impedance matching in special applications.
Instrument Transformer: An instrument transformer is a device used to measure parameters such as current, voltage, and power, typically used as part of a transformer.
Common causes of transformer failure
1. Overload: Long-term overload operation leads to aging of the internal insulation of the transformer, which leads to failure.
2. Lightning strikes: The overvoltage generated by lightning may damage the transformer insulation and cause faults such as short circuit.
3. Short circuit: Short circuit fault caused by external reasons (such as branches, nests, etc.) or internal reasons (such as winding insulation damage).
4. Improper maintenance: The long-term lack of necessary maintenance and inspection makes the transformer a potential safety hazard.
Hidden costs of transformer maintenance
Repair service fee: Professional repair service providers usually charge a certain amount of man-hour fee, which will vary depending on the complexity and time taken to repair the job. In addition, some service providers may also charge travel fees or service fees.
Shutdown loss: During transformer maintenance, equipment downtime may lead to production interruption, which will affect the normal operation and revenue of the enterprise. This loss of downtime is a hidden economic burden that businesses need to consider in their maintenance plan.
Equipment size and fault type: Larger-scale dry type transformers usually require more labor and materials, so maintenance costs will be relatively high. At the same time, different types of failures may require different maintenance methods and processes, which will also affect the cost of maintenance.
Parts cost: Electrical parts, insulation, or other critical parts of the transformer may need to be replaced during the repair process. The cost of these parts depends on factors such as their make, model and specifications, and can account for a large part of the total cost of repair .
Maintenance and service costs: Regular maintenance and service can reduce the occurrence of unexpected breakdowns, but these work also require a certain cost. If not properly maintained, it can lead to greater repair needs and higher hidden costs.
Environmental costs: Waste and pollutants generated during transformer maintenance may have a certain impact on the environment, requiring investment in environmental protection treatment and monitoring.
Management cost: In order to ensure the smooth progress of maintenance work, it is necessary to invest certain manpower and material resources for project management, communication and coordination.
Ways to reduce the hidden cost of transformer maintenance
Regular maintenance and maintenance: Through regular inspection and maintenance, you can find and solve potential problems in time, reduce the occurrence of sudden failures, thereby reducing maintenance costs and downtime loss.
Select high quality parts: When replacing parts, choose high quality and high reliability parts, you can reduce the number of maintenance and cost caused by parts failure.
Optimize maintenance plan: Reasonably arrange maintenance time and process, reduce downtime, improve maintenance efficiency, so as to reduce the loss of downtime .
Training professional maintenance personnel: By training professional maintenance personnel, the quality and efficiency of maintenance work can be improved and the additional cost caused by improper maintenance can be reduced.
