Application of Hall current sensor in frequency converter

With the continuous deepening of economic reform, energy conservation and consumption reduction have become one of the important means to reduce production costs and improve product quality. Variable frequency speed regulation technology meets the requirements of industrial production automation development and has opened up a new era of intelligent motors. At present, this technology has been applied in many industries such as electricity, metallurgy, chemical industry, papermaking, food, textile, etc. It has become the main development direction of modern power transmission technology. By using a frequency converter to control the speed of the motor, more than 10% of electrical energy can be saved. Hall current sensors are becoming increasingly outstanding in frequency converters as sensors for monitoring their current characteristics.

Application of Hall Current Sensor in Photovoltaic DC Cabinet

Photovoltaic DC cabinet is a functional cabinet that can collect, monitor, and protect DC current after the convergence of photovoltaic combiner boxes. The DC lightning protection cabinet can converge multiple DC inputs into one current output. Each channel has protective devices (circuit breakers, fuses, etc.), anti reverse diodes, etc., and can monitor and control the voltage and current of each channel. Hall current sensors are mainly used to monitor the real-time output current of the current. Photovoltaic combiner box. Based on the open-loop (direct release) principle in practical applications, the structure of this sensor is relatively compact, with low power consumption and low cost. The open-loop (direct release) principle Hall current sensor is widely used in photovoltaic DC cabinets and is used in conjunction with the photovoltaic DC cabinet busbar acquisition device.
