摘　　要：直直流融冰是最为有效的线路融冰方法,目前已有多种结构型式的直流融冰装置投入实际运行。但融冰装置目前都没有相关标准或规范对其阀侧电压互感器的配置提出明确要求。文章基于直流融冰装置电流控制原理,分别探讨了固定式、移动式、兼做SVC直流融冰装置阀侧电压互感器配置策略,实践应用表明:固定式直流融冰装置可不配置阀侧电压互感器;移动式直流融冰装置宜配置阀侧电压互感器;兼做SVC直流融冰装置需配置阀侧电压互感器。DC de-icing is the most effective method for ice melting.At present,multiple structural types of DC de-icing devices have been put into practical operation.However,the de-icing device does not have either related standard or specification with specific requirement to the valve side voltage transformer configuration.In this paper,the configuration strategy of valve side voltage transformer of the fixed,mobile and SVC DC de-icing device is discussed respectively based on the current control principle of DC de-icing device.It is shown by the practical application that the fixed DC de-icing device cannot be equipped with the valve side voltage transformer;the mobile DC de-icing device and the SVC de-icing device shall be equipped with the valve side voltage transformer.
