The application of resistors in wind turbine units is essential for the efficient operation of the equipment. There are various types of resistors used, including pre-charge resistors, chopper resistors, filter resistors, and more. Each type of resistor serves a specific purpose in controlling and managing the flow of electrical currents within the wind turbine system.
One of the crucial types of resistors used in wind turbine units is the Aluminum Housed Resistor. This resistor plays a critical role in limiting surge currents from entering the DC circuit when the switch is turned on. In order to meet the requirements of this application, the pre-charge resistors needs to have high single-pulse energy and high rated voltage. One of the ideal products for this purpose is the trapezoidal aluminum shell resistor manufactured by Aochuang Electronics. This resistor is characterized by its high power capacity and strong resistance to pulse energy. Additionally, its wire-wound structure helps to limit surge currents, making it a suitable choice for wind turbine applications.
Another important type of resistor used in wind turbine units is the chopper resistor. When the chopper switch is turned on, the chopper resistor serves to limit the flow of current. Chopper circuits typically operate at very high frequencies to control DC voltage, and as such, the chopper resistor must have low parasitic inductance in order to function properly at kilohertz-level switching frequencies. This requirement can be fulfilled through the use of thin film technology. Additionally, to meet the demand for high rated power in a compact size,Aluminum Housed Resistor with optional heat sinks are used, which can be installed in the heat dissipation system similar to the chopper switch.
The ASZ series Aluminum Housed Resistor from ZENITHSUN is a prime example of a well-selected resistor for wind turbine applications. It is constructed with a high thermal conductivity aluminum shell (aluminum content exceeding 90%), sealed with high-temperature resistant silicone resin and silicon powder for environmental safety. The resistor’s wire frame is made of ceramic, and the resistor wire is made of constantan and nickel-chromium,ensuring heat resistance, high temperature resistance, stable performance, and long service life. Its easy installation and compatibility with additional heat sinks make it suitable for use in high-demand and harsh environments, making it widely used in the field of wind turbines.
Overall, the proper selection and application of resistors in wind turbine units are crucial for ensuring the efficient and safe operation of the equipment. Manufacturers and operators must carefully consider the specific requirements of each type of Aluminum Housed Resistor and select products that meet the high standards for power capacity, pulse energy resistance, and environmental safety.By utilizing advanced technologies and high-quality materials, the wind turbine industry can continue to improve the performance and reliability of its equipment for sustainable energy generation.
