3/2断路器接线方式下电流互感器接线计量误差分析 The Measurement Error Analysis of the Current Transformer Connection under Way in 3/2 Circuit Breaker Main Electrical Connection

根据3/2断路器接线方式下电流互感器的“和相”接线特点，详细分析了并联运行电流互感器的“和电流”误差特性，以及提出了该接线方式下对电流互感器误差一致性和对电网运行方式的具体要求，以减小接线因素的影响。 According to the “and phase” current connection characteristics of the transformer under way in 3/2 circuit breaker main electrical connection, the current transformer parallel operation “and current” error characteristics are analyzed in detail. In addition, the paper puts forward the error consistency of current transformer and the specific requirements for the operation mode of the grid in order to reduce the influence of the connection factors.
