摘　　要：在详细分析了圆形和四边形阻抗继电器的基础上，提出了自适应碗形阻抗继电器新原理。它通过扩大常规姆欧继电器的动作区，极大地提高了允许过渡电阻的能力，具有动作判据简捷、速度快、技术成熟、整定方便、选相能力强、方向明确、测距精确、躲负荷阻抗能力强、便于实现自适应等突出优点，仿真计算和整机试验验证了理论分析的正确性，并已在最新研制的微机距离保护中得到应用。Adaptive impedance relay of bowl shape has been put forward in this paper,on thebasis of detailed analyses of circular and quadrilateral impedance relays,which can stand hightransition resistance by means of expanding operation zone of traditional MHO relay.It ischaracterized by simple criterion,fast operation,mature technique. easy setting,good phaseselection. distinct directionality.accurate distance measurment.high security in heavy load andeasy to realize adaption. Simulating calculation and pratical test have verified the analyses. The BOWL relay has been applied in microprocessor-based distance protection developed by ourinstitute.
