Role
Transformer is a very common power measurement equipment, mainly used to convert high voltage signals into low voltage signals for subsequent measurement, calculation and protection. In the operation of the power grid, the transformer is mainly used in the following aspects:
1. Power supply protection: The transformer can provide a reliable measurement signal for the protection equipment by converting the high voltage signal into a low voltage signal, so as to realize the power supply protection of the power system.
2. Electric energy metering: The voltage transformer can provide a low voltage signal to measure the voltage value of electric energy, which provides a guarantee for the electric energy metering of the power grid.
3. Power grid control: The transformer can be used as an important part of the power grid control to provide accurate and reliable voltage signals for the control and dispatch of the power grid.
Principle
The principle of transformer is the principle of transformer, which uses transformer to change high voltage signal into low voltage signal. The basic composition of the transformer includes a high-voltage winding, a low-voltage winding and an iron core.
When the transformer is working, the high-voltage winding transmits a high-voltage signal to the transformer, converts the high-voltage signal into a low-voltage signal through mutual inductance, and the low-voltage winding receives the low-voltage signal and outputs it.
The iron core is used as a carrier for conducting high-voltage signals, which makes the transmission of high-voltage signals more stable and reliable. The output signal of the transformer can be tested and protected in the form of analog signal or digital signal.
Advantage
Voltage transformer plays an important role in the operation of power system. Compared with other measuring equipment, transformer has the following advantages:
1. Wide measurement range: The transformer can be applied to changes in various voltage levels and has a wide measurement range.
High precision: The transformer has the advantage of high precision when measuring voltage, which can provide accurate and reliable signals for protection equipment.
3. Safe and reliable: When the transformer transmits a high-voltage signal, it can be turned into a low-voltage signal output, thereby ensuring the safety of equipment and personnel.
4, easy maintenance: transformer as a conventional measuring equipment, in terms of maintenance and replacement also has a certain degree of convenience.
Voltage transformer is an important part of the operation of the power grid, it plays an important role in the protection, measurement, control and scheduling of the power grid, by understanding its role, principle and advantages, users can better use it in order to better deal with the related problems in the operation and protection of the power grid.
