描述
ABB ACBU-A1是一款应用于风电领域的有源Crowbar控制模块，其零件号为3AFE68312574。以下是其产品详情：
产品类型：内部控制板/电子模块。
兼容设备：主要应用于ABB ACS800-67系列双馈风力发电变流器。
功能特点：
过电流和电网故障保护：在电网发生电压暂降、短路等故障时，或在变流器内部出现过电流情况时，ACBU-A1模块能快速启动保护机制。
有源Crowbar控制：精确控制“Crowbar”电路的动作，通过在转子侧电路中快速引入一个阻性或感性元件，来限制故障电流，防止IGBT等功率器件损坏。
确保系统稳定性：通过有效保护变流器和发电机，帮助风力发电系统在电网扰动下保持稳定运行，并快速从故障中恢复。
环境参数：工作温度为-40℃至+85℃，相对湿度为5%至95%。
The ABB ACBU-A1 is an active crowbar control module for wind power applications.Its part number is 3AFE68312574.The following are product details:
Product Type:Internal Control Board/Electronic Module.
Compatible Devices:Primarily used with the ABB ACS800-67 series of doubly-fed wind turbine converters.
Features:
Overcurrent and Grid Fault Protection:The ACBU-A1 module quickly activates protection mechanisms in the event of grid faults such as voltage sags and short circuits,or in the event of overcurrent conditions within the converter.
Active Crowbar Control:Precisely controls the operation of the”crowbar”circuit,quickly introducing a resistive or inductive element into the rotor-side circuit to limit fault current and prevent damage to power devices such as IGBTs.
Ensuring System Stability:By effectively protecting the converter and generator,the wind turbine system maintains stable operation during grid disturbances and quickly recovers from faults.Environmental parameters:operating temperature is-40℃to+85℃,relative humidity is 5%to 95%.
