Current sensors, also known as magnetic sensors, can be used in household appliances, smart grids, electric vehicles, wind power generation and so on. Many magnetic sensors are used in our lives, such as computer hard disk, compass, household appliances and so on.
Classification of current sensors:
Current sensors can be divided into shunt, electromagnetic current transformer and electronic current transformer according to different measuring principles.
The electronic current transformer includes Hall current sensor, Rokowski current sensor and frequency conversion power sensor (which can be used for voltage, current and power measurement), etc.
Compared with electromagnetic current transducer, electronic current transducer has no ferromagnetic saturation, wide transmission frequency bandwidth, small secondary load capacity, small size, light weight, and is the future development direction of current transducer.
Application of current sensors:
Current sensors are used in wind power generation: wind energy, as a clean and renewable energy, has attracted more and more attention in the world.
Wind has been used for a long time - mainly by windmills to pump water, grind surfaces, etc. In the new century, people are interested in how to use wind to generate electricity and how to maximize power generation. Current sensor, as the main detection component, plays a vital role in it.
