ELECTRIC, WITH AN EDGE
This article mainly discusses the selection of 1000kV transformer voltage regulation mode and operation and maintenance.
Unlike the traditional 500kV autotransformer, the 1000kV transformer uses a neutral non-excitation voltage regulating autotransformer.
Applying the 1000kV transformer to the operation of the power system effectively compensates for the shortcomings in the operation of the traditional transformer, and plays an extremely important role in realizing the safe transmission of electric energy and fully satisfying different power demands.
Especially with the rapid development of the social economy and the continuous expansion of the industrial production scale, the demand for electricity is also increasing.
The 1000kV transformer is applied to the power system, and the voltage is raised or lowered according to the power demand at all levels to fully meet the power demand of industrial production and social life.
This article mainly starts from the characteristics of 1000kV transformer, analyzes the selection of 1000kV transformer, and puts forward scientific suggestions for the safe and stable operation and maintenance of 1000kV transformer.
The application of a 1000kV transformer in the power system plays a very important role. The 1000kV transformer has two main functions: First, it increases the voltage to ensure that the electric energy can be safely transmitted to the electricity-consuming area;
Second, reduce the voltage to the voltage used at all levels to fully meet different power needs.
Unlike traditional transformers, 1000kV transformers have more obvious advantages.
The 1000kV transformer uses a neutral non-excitation voltage-regulating autotransformer. A single autotransformer can effectively reduce its own volume and weight, save costs, reduce losses, and improve operating efficiency. Applying it to the power system can improve the system Stable performance, which plays an extremely important role in the safe and stable operation of the power system.
In addition, from an economic analysis, it can be found that the autotransformer for 1000kV transformer is a more reasonable choice, mainly because it can be equipped with a backup transformer in the system, and when a transformer fails, it can be operated as a backup immediately. The transformer promotes the power system to resume operation, minimizes losses, improves the economic benefits of the power system operation, and fully meets the power needs of users.
Under the same circumstances, it is difficult for the transformer of the three-phase community to resume normal operation in a short period of time, thus causing incalculable losses to the power industry.
Therefore, it is very necessary to apply a 100kV single autotransformer in power system operation.
Transformers can be divided into two types of voltage regulation, on-load voltage regulation and non-excitation voltage regulation, while the 1000kV transformer adopts the non-excitation voltage regulation method.
The application of the non-excitation voltage regulation method can effectively avoid the defects in the application of the on-load voltage regulation method, and effectively improve the reliability of the related equipment of the power system.
There are many problems in the application of on-load voltage regulation. It not only carries unreliable factors on its own but also causes damage to other equipment in the power system.
In addition, the application of on-load voltage regulation will increase operation and maintenance costs, which will have an extremely adverse effect on improving the economic benefits of the power system.
Therefore, the non-excitation voltage regulation method should be selected in the operation of the power system, and the 1000kV transformer adopts the non-excitation voltage regulation method.
The connection mode of autotransformer and voltage regulating transformer can be divided into 3 kinds:
First, connect the windings of the voltage regulating transformer directly in series with the medium voltage terminal line of the main transformer;
Second, connect the winding of the voltage regulating transformer in series to the end of the series winding of the autotransformer;
Third, connect the voltage regulating transformer winding in series at the neutral point of the main transformer, and then connect the excitation winding of the voltage regulator and the winding of the main transformer in parallel.
Through the comparison of these three connection methods, it is found that the neutral point voltage regulation is the best connection method.
It can effectively reduce the tap current and minimize the switching cost.
This has an extremely beneficial effect on improving the economic efficiency of power system operation.
In short, through the analysis of the characteristics of the 1000kV transformer, it can be found that the operation stability and economy of the 1000kV transformer are better.
In the transformer connection mode, the neutral point connection is the best voltage-regulating connection mode.
In the choice of 1000kV voltage regulating transformer, single autotransformer and non-excitation voltage regulating method are the best choices.
Because they can not only ensure the safe and stable operation of the power system but also improve the economic benefits of the operation of the power system.
It is conducive to fully satisfying the electricity demand of industrial production and social life, which has an extremely important influence on the realization of the long-term development goals of the electric power industry.
During the operation of the 1000kV transformer in the power system, the oil temperature will directly reflect the operating status of the transformer. A full grasp of the oil temperature can provide a guarantee for the stable operation of the transformer;
The oil level can also reflect the operating status of the transformer, which requires relevant personnel to monitor the relationship curve between the oil level and the oil temperature at any time.
If there is an abnormal situation, it is necessary to take effective measures in time according to the chromatographic standard to lay the foundation for the safe operation of the transformer.
Finally, the chromatogram is an important criterion for judging the operating status of the transformer, and the operating status of the transformer must be grasped in real-time.
Accurately analyze the data of the 1000kV transformer, establish a long-term data analysis file in the operation and maintenance of the transformer, and provide a scientific theoretical basis for the later operation and maintenance.
In the operation and maintenance of 1000kV transformers, it is necessary to strengthen the monitoring of the cabinet and the cooling system.
Strictly check the box for oil leakage.
Perform temperature measurement regularly to fully grasp the operating status of the transformer.
At the same time, it will do a good job of data analysis and recording to provide a scientific theoretical basis for subsequent operation and maintenance.
In addition, it is also necessary to strengthen the supervision of the cooling system to ensure that the cooling system can work normally.
This requires the operation and maintenance personnel of the power system to regularly check the running status of the fan and replace it regularly to promote the normal operation of the cooling system.
In the inspection work, if it is found that the transmission road is close to the rated load, it is necessary to strengthen the loop control.
The addition of appropriate power cooling conditions lays a solid foundation for the safe and stable operation of the 1000kV transformer.
In the application of 1000kV transformer, the most important job is to regularly maintain the 1000kV transformer.
Only by doing a good job in transformer maintenance, discovering possible problems in transformer operation in time, and proposing corresponding solutions, can we provide sufficient guarantee for the transformer to fully function.
In summary, the application of 1000kV transformers in power systems plays a very important role.
It can promote the safe and stable operation of the power system while saving costs, and fully meet the power needs of users.
However, in order to ensure the normal operation of the transformer, the transformer must be maintained on a regular basis. Only in this way can the important role of the transformer be brought into full play.
