摘要
为了解决互感器装置功耗大、绝缘性能差,且现场校验误差大的问题,设计一种全新型特高压直流电流互感器装置,并提出相应校验技术。根据磁感应强度、磁通密度确定线圈铁芯的材料;采用多模光纤完成光纤传输信道的传输;以能耗最小,能量转换率最大为目的确定互感器装置供能方式,完成互感器装置设计。采用模拟电压方式输出设计的装置电压,若输出电压为一次电压,则采用差值技术完成校验,若输出电压为二次电压,则使用直接检测技术完成校验。实验结果表明,所提设计能够降低互感器装置功耗,并能够及时校正互感器装置偏差,并能保证校验效率,确保特高压输电系统作业环境的安全。
In order to solve the problems of high power consumption,poor insulation performance and large field calibration error of the transformer device,a new type of UHV DC current transformer device is designed and the corresponding calibration technology is proposed.Determine the material of the coil core according to the magnetic induction strength and magnetic flux density;Multimode optical fiber is used to complete the transmission of optical fiber transmission channel;Determine the energy supply mode of the transformer device for the purpose of minimum energy consumption and maximum energy conversion rate,and complete the design of the transformer device.Analog voltage is used to output the designed device voltage.If the output voltage is primary voltage,the difference technology is used to complete the calibration.If the output voltage is secondary voltage,the direct detection technology is used to complete the calibration.The experimental results show that the proposed design can reduce the power consumption of the transformer device,correct the deviation of the transformer device in time,ensure the calibration efficiency,and ensure the safety of the operating environment of the UHV transmission system.
