The variable frequency transformer comprehensive tester is a specialized equipment used to test the performance of current transformers (CT) and voltage transformers (PT), with a wide range of applications covering multiple fields of power systems. The specific application scope is as follows:
1. Testing and maintenance of power system equipment
① Substation and power plant
Periodic testing of transformers: Conduct periodic tests on CT and PT in substations and power plants to ensure their performance meets operational standards and prevent system accidents caused by transformer failures.
New equipment acceptance: In new or expanded projects, comprehensive performance verification of newly installed transformers is carried out using testing instruments to ensure the quality of equipment operation.
② Power equipment maintenance
Fault diagnosis: Through tests such as volt ampere characteristics and transformation ratio, quickly locate problems such as saturation and polarity errors in transformers, and guide maintenance decisions.
Preventive maintenance: Based on test data, evaluate the aging degree of transformers, develop a scientific maintenance plan, and extend the service life of equipment.
2. Construction and Renovation of Power System Engineering
① New construction and expansion projects
Equipment selection criteria: Provide transformer performance testing data for the project, assist in selecting equipment with matching technical parameters, and ensure system compatibility.
Construction quality acceptance: During the completion stage of the project, acceptance testing is conducted on the installation quality of the transformer to verify whether it meets the design requirements.
② Upgrading and renovating the power grid
Performance evaluation of old equipment: Before replacing or upgrading transformers, obtain existing equipment performance parameters through testing to provide data support for renovation plans.
New equipment debugging: Conduct performance debugging on the transformer installed after renovation to ensure its coordinated operation with the new system.
3. Power system operation management and quality control
① Running status monitoring
Real time data collection: Combined with an online monitoring system, conduct regular spot checks on key transformers to grasp the trend of equipment operation status changes.
Abnormal warning: By comparing long-term test data, signs of transformer performance degradation are discovered, and potential risks are warned in advance.
② Quality control system
Factory inspection: Transformer manufacturers use testers to conduct product factory inspections to ensure that the delivered equipment meets technical standards.
Third party testing: As an independent testing tool, it provides objective performance evaluation basis for power system procurement.
4. Special application scenarios
① Special environment testing
High altitude areas: Conduct special tests on the performance changes of transformers in low-pressure environments to ensure equipment adaptability.
Extreme temperature conditions: Verify the accuracy retention ability of transformers at different temperatures in areas with severe cold or high temperatures.
② Special type transformer testing
TP type transformer: Conduct precise transient characteristic testing on transformers used for transient protection to ensure the reliability of relay protection.
Electronic Transformer: Adapt to the testing requirements of new digital transformers and support the construction of smart grids.
5. Summary of Application Value
Ensure system security: Reduce the risk of transformer failure through precise testing and maintain stable operation of the power grid.
Improve operation and maintenance efficiency: Integrated testing functions reduce on-site operational steps and shorten maintenance downtime.
Optimizing cost investment: A scientific maintenance strategy based on performance evaluation to avoid excessive maintenance or premature scrapping of equipment.
Support technology upgrade: Provide testing methods for the validation of new transformer technologies and promote the intelligent development of power systems.
