RPCB 系列叠成电阻(Crowbar)采用的是用不锈钢带折叠起来，片与片之 间用云母作为绝缘层。Crowbar电阻器--低电压穿越技术Crowbar电阻主要 应用于风力发电逆变器的低电压穿越技术中。它用在风力发电机转子侧， 用于旁路转子侧变流器。当电网发生低电压扰动时，防止直流母线电压过 高和转子电流过大。主要工作在故障状态，阻尼定子磁链。Crowbar电阻能 在瞬时把巨大能量耗散掉。

RPCB he series resistance (Crowbar) is made of stainless steel tape and folded between film and film.. Crowbar resistor - the low voltage ride through technology Crowbar resistor is mainly applied to the low voltage ride through technology of wind power inverter. It is used in the rotor side of the wind generator and is used for the bypass rotor side converter.. When the power grid occurs when the voltage disturbance is low, the DC bus voltage is too high and the rotor current is too large.. Mainly in the fault state, damping stator flux linkage. Crowbar resistance can dissipate the enormous energy
