摘要
直流电流互感器作为直流输电系统的重要一次设备,为输电系统的控制、保护和测量提供了关键的信息和可靠的凭证。它的稳定运行直接关系到整个换流站的安全生产运行,乃至关系到中国能源输送网架结构的完整性和安全性。而目前业界对直流互感器现场试验缺乏统一而又行之有效的方法。本文将对多种直流电流互感器的现场试验方法的优缺点进行对比,初步建立对直流互感器评价的体系,供设备使用者和检修策略制定者提供参考依据。
DC current transformer as the most important primary equipment of HVDC transmission system, which pro-vides stable and reliable signals and information to the transmission system for control, protection and measuring equip-ment. The operation of DC current transformer in steady and safety is directly related to the safe-production operation of the converter station. And even in relation to the integrity and security of the entire structure of the power-supply grid be using in China's energy transport. At present, the industry of DC transformer consider the method using in the DC cur-rent transformer’s field test has the lack of unified and effective. The advantages and disadvantages of the various DC current transformer field test methods are compared, and the initial establishment of the DC transformer evaluation has been raised. The essay shows some efficacious and feasible strategies for equipment users as a reference basis.
