Load Tap Changer (LTC)
Farkon
Gin tap position under load: Tap position yana iya canzawa idan transformer tana da muhimmanci bane da shiga cikin power supply.
Adjust the output voltage: Adjust the output voltage by changing the transformer ratio to adapt to different load requirements.
Peculiarity
Flexible operation:tap position yana iya canzawa bane da shiga cikin power failure.
Automatic or manual control: Automatic or manual adjustment can be achieved to adapt to different application scenarios.
Wide adjustment range: there are usually more tap positions to provide finer voltage regulation capabilities.
High complexity: The structure is relatively complex and requires more maintenance.
Application scenario
Power system: Widely used in power transmission and distribution networks to adapt to different load changes.
Industrial sector: Used in factories and large facilities to ensure a stable voltage supply.
No-Load Tap Changer (NLTC)
Farkon
Change tap position when not under load: Tap position yana iya canzawa idan transformer ba tana da muhimmanci bane da shiga cikin power supply.
Adjust the output voltage: Adjust the output voltage by changing the transformer ratio, but it needs to be carried out under no-load conditions.
Peculiarity
Simple structure: Compared with on-load tap-changer, the structure is simpler and the maintenance cost is lower.
Easy operation: Usually manually operated by simple mechanical or electric means.
Limited adjustment range: Few tap positions are provided and the adjustment range is relatively narrow.
Application scenario
Small transformers: Suitable for small transformers or applications that do not require frequent adjustment of tap positions.
Specific applications: In situations where frequent voltage regulation is not required, or in cost-sensitive applications.
Maintenance and inspection
Regular inspection: Whether the tap-changer is loaded or unloaded, it needs regular inspection and maintenance to ensure that it works properly.
Lubrication: Regularly lubricate the moving parts of the tap-changer to reduce wear.
Clean: Remove dust and dirt around the tap-changer to avoid affecting operation.
Electrical check: Check the electrical connection of the tap-changer to ensure good contact.
Matters needing attention
Safe operation: When maintaining or adjusting the tap position, observe the safe operation rules.
Environmental adaptability: Select the tap changer that is suitable for local environmental conditions.
Conclusion
By using on-load tap-changer and no-load tap-changer, the output voltage of the transformer can be adjusted according to actual needs, so as to ensure the stability and reliability of the power supply system.
