Shunts FL-2, also known as a current shunt or current divider, is an electronic component that plays a role in diverting current in a circuit. It allows the current to flow through different paths by providing a low-resistance alternative path.

Function:

Current diversion: Shunts diverts current from one portion of a circuit to another, effectively splitting the current flow. It can guide the current to other branches or loads as required, enabling precise current control and distribution.

Current measurement: Shunts are commonly used for measuring current in a circuit, especially high currents. By placing the shunts in the current path, the current value can be derived by measuring the voltage across the shunts, following Ohm’s law.

Features:

• Low resistance: Shunts typically have low resistance to minimize energy loss during the diversion process. Their low-resistance characteristics enable them to withstand high currents without overheating.
• Precision: Shunts are designed with high accuracy, providing precise current measurement results. This is crucial for applications that require precise current control and measurement.
• High-temperature tolerance: Due to their frequent operation in high-current and high-power environments, shunts often exhibit good resistance to high temperatures, allowing them to operate stably under elevated temperature conditions for extended periods.
• Mechanical properties of resistance:Can withstand acceleration of 70 m/s ² and impact frequency of 6 hours of 80 to 120 beats per minute transport point earthquake.
• Heat load: Changes in temperature stabilized, does not exceed the rated current of 50A below 80 ºC; rated current of 50A above does not exceed 120 ºC.

Applications:

• Power systems: Shunts find wide applications in current measurement and control within power systems. For instance, they are used in substations to measure currents in transmission lines, ensuring the normal operation and load balancing of the power grid.
• Electronic measurement instruments: In laboratories and industrial settings, shunts are commonly employed in current measurement instruments such as digital multimeters, ammeters, and other testing equipment. They provide accurate current measurement for various circuit testing and troubleshooting purposes.
• Electric vehicles: Shunts are used in electric vehicles and hybrid vehicles to measure currents in electric motors and battery systems, enabling monitoring and control of energy flow, ensuring efficient energy management and safe operations.
• Welding equipment: In welding devices like arc welders and gas metal arc welding (GMAW) equipment, shunts are utilized to measure welding currents, ensuring welding quality and stability.

In summary, a shunt is an electronic component used for current diversion and measurement. It possesses characteristics such as low resistance, high precision, and high-temperature tolerance. Shunts have broad applications in power systems, electronic measurement instruments, electric vehicles, welding equipment, and more. By utilizing shunts, we can achieve precise control, measurement, and distribution of current, ensuring the proper functioning of circuits and efficient system performance.
