Gudanar da Voltage
Gudanar da output voltage: Ta haka a gudanar da ratio na transformer, za a iya gudanar da output voltage don ya ci a wannan lokacin. Wannan yana da muhimmanci sosai ga gudanar da voltage a grid, musamman a lokutan da aka samu abubuwan ladda masu yawa ko fluctuation na grid voltage.
No-load regulation: Tap position ana gudanar amma transformer ba ake ladda, wanda yana daidai a cikin lokutan da ba a bukata gudanar da yawa.
On-load voltage regulation: allows the tap position to be adjusted when the transformer is loaded, which is suitable for frequent voltage regulation.
Load matching
Adapt to load changes: By adjusting the transformer ratio, the load demand can be better matched to ensure the stability and reliability of the power supply.
Fault protection
Overvoltage protection: When the power grid voltage is too high, the output voltage can be reduced by adjusting the tap to protect downstream devices from overvoltage.
Overload protection: When the load is too large, the current can be reduced by adjusting the tap to avoid the overload of the transformer.
System equilibrium
Balanced voltage distribution: When multiple transformers are running in parallel, the voltage distribution between the transformers can be balanced by adjusting the tap to ensure the stability of the system operation.
Economic operation
Energy-saving operation: By adjusting the tap, the operation state of the transformer can be optimized, the energy loss can be reduced, and the economy of the system can be improved.
Tap position
Taps are usually set on the high voltage side winding of the transformer, because the high voltage side of the current is smaller, it is easier to achieve the switch of taps. In some special cases, taps may also be installed on the low pressure side.
Types of taps
According to different use occasions and needs, taps can have different types:
Fixed tap: The position has been set at the time of manufacturing, and cannot be adjusted.
Adjustable tap: Allows the position to be adjusted on the fly to suit different operating requirements.
Load regulator tap: can be adjusted with load, suitable for frequent adjustment.
No load regulator tap: can only be adjusted when the load is disconnected, suitable for situations that do not require frequent adjustment.
Tap switching device
In order to achieve the switching of taps, special switching devices need to be used, common are:
Tap changer: It is used to switch the tap position during the operation of the transformer, which is divided into no-load tap changer and on-load tap changer.
Switching switch: Used to manually or automatically switch the tap position in the state of power failure.
Application scenario
Transformer taps are widely used in all aspects of power systems:
Power transmission: In long-distance transmission, the line voltage drop is compensated by adjusting the tap to ensure that the end voltage is stable.
Distribution network: In the urban distribution network, the tap is adjusted to cope with load changes in different periods of time to maintain voltage stability.
Industrial applications: In industrial electrical equipment, the tap is adjusted to meet the voltage requirements under different load conditions.
