The application of Power Resistors in power facilities mainly includes the following aspects:
Current Limitation: Resistors can be used to limit current, protecting other components in the circuit from overload and damage.
Voltage division: In power facilities, resistors can be used as voltage dividers to distribute voltage to different parts of the circuit to meet the needs of different equipment.
Load Simulation: When testing and maintaining power equipment, resistors can be used as load simulators to ensure the performance of the equipment under different load conditions.
Thermal Management: In some applications, resistors generate heat, which can be used for heating or temperature control.
Filtering: Resistors combined with capacitors or inductors can form filters to remove noise and interference from power systems.
Energy Measurement: Resistors are used for current measurement and power measurement, helping to monitor and manage the performance of power systems.
The porcelain tube type starting wire wound Power Resistor is formed by winding a certain number of turns of resistance alloy wire on a porcelain tube with spiral grooves. This starting resistor has high power, is durable, and has good high temperature resistance and heat dissipation performance. The resistance temperature coefficient is low and changes linearly, which is suitable for short-term overload of large current. It is suitable for motor starting, load testing, industrial machinery, power distribution, instrumentation and automatic control devices.
Aluminum shell Power Resistors are composed of aluminum alloy resistor body and formed aluminum shell. After high-temperature anodization, they are filled and fixed with special non-combustible heat-resistant cement. They are resistant to mechanical external forces and dusty environments. This type of resistor is not only powerful, but also strong, shock-resistant, and has good heat dissipation. The temperature coefficient of resistance is small and changes linearly. It is suitable for industrial machinery, load testing, power distribution, instrumentation, automatic control devices, etc.
These applications make resistors play an important role in power facilities, ensuring the safe and stable operation of the system.
