What is a resistive shunt, its characteristics, principles, common faults, and preventive measures 2

Classification:

According to the characteristics and applications of resistive shunts, they can be divided into the following categories:

1. Fixed resistor shunt: It is composed of fixed resistors and cannot change the voltage division ratio.

2. Variable resistor shunt: composed of adjustable resistors that can change the voltage division ratio.

3. Optical resistor shunt: Use a variable optical resistor for voltage division.diode

4. Digital resistor shunt: Use digital switches to control the voltage division ratio.diode

Common faults and preventive measures:

1. Resistance value change: Regularly check the resistance value and replace the faulty resistor.

2. Poor connection: Maintain a good connection to ensure good contact between the resistor and other components.

3. Overheating: Choose resistors with appropriate power capacity and ensure good heat dissipation.

4. Accuracy error: Select resistors with high accuracy and calibrate and adjust them.

Summary: A resistive shunt is a common circuit component that can be used for voltage regulation and current control. It is composed of resistors and divides current according to Ohm's law. There are various types and application scenarios of resistive splitters, so it is necessary to make a reasonable selection and use according to actual needs, and pay attention to maintenance and preventive measures to ensure their normal operation and reliability.diode
