2BU63R

2BU63R Application Field and Working Principle

2BU63R is a comprehensive relay designed for high-voltage, low-voltage systems and agricultural intelligent distribution. It is suitable for the protection and control of AC power systems and equipment. This relay is composed of an integrated protection and control unit, an analog-digital scanning unit, an analog-digital conversion unit, and a transformer for power supply and operation.

Application Field

2BU63R is mainly used for the following types of AC control and protection, such as: overcurrent protection, undercurrent protection, three-phase unbalance overcurrent protection, overload protection, motor protection, locked rotor protection, short-circuit protection, arc protection, voltage protection, etc. In addition, it can also be used for remote meter reading and output of various automatic control signals.

Working Principle

2BU63R relay is composed of an integrated protection and control unit, an analog-digital scanning unit, an analog-digital conversion unit, and a transformer for power supply and operation.

In the integrated protection and control unit, the operation circuit of the command contacts is activated by the output of the analog-digital scanning unit. The analog-digital conversion unit converts the analog quantity input by the analog signal input port into digital values, and sends it to the analog-digital scanning unit for processing. The output of the analog-digital scanning unit is connected to the integrated protection and control unit for operation.

The input and output of the 2BU63R relay is connected to a transformer, and the voltage and current of each output signal of the system are regularly scanned and converted to analog signals. All of these signals are sent to the analog-digital conversion unit, and then analyzed and processed by the analog-digital scanning unit. After that, the command contact of the integrated protection and control unit is actuated. The output signals are further fed back to the system.

By using the analog-digital conversion and analog-digital scanning units, 2BU63R relay can not only effectively protect various electrical systems and equipment, but also provides a convenient way to read the data. In addition, it has the function of remote control, which brings great convenience to the operation of the circuit.

Conclusion

2BU63R relay is a comprehensive relay designed for high-voltage, low-voltage systems and agricultural intelligent distribution. It is mainly used for the AC control and protection of overcurrent, undercurrent, overload, short-circuit, arc, voltage, etc. The modular design of the system makes it more reliable and easy to use. The analog-digital conversion and analog-digital scanning units provide an effective way for data processing, and the ability to remotely control the system makes operation more convenient.
