Abstract

The secondary circuit in substations is in a strong electromagnetic environment, and intelligent devices may be affected by electromagnetic disturbance signals. Meanwhile, with the local installation of intelligent devices, the electromagnetic disturbance of its working environment may be further strengthened. In recent years, there have been many accidents about abnormal operation of intelligent devices caused by the disturbance of secondary circuit in substations by circuit breaker and isolation switch. Therefore, it is with great significance to study the electromagnetic compatibility issue of the secondary circuit in substations. This paper has tested and recorded the electromagnetic disturbance in TA&TV secondary side of the local cabinet in the 500kV substation caused by the dead tank and live tank type circuit-breaker. The time domain and frequency domain of the measurement results are analyzed, the result of which indicates that the amplitudes of electromagnetic transient signals caused by the dead tank type breaker operation are all greater than that caused by the live tank type of breaker operation. However, the frequency of disturbance signals caused by dead tank circuit breaker is mostly concentrated in the KHz level, but that caused by the live tank type of breaker is distributed in the high-frequency section of MHz. Finally, some suggestions are proposed to improve the electromagnetic compatibility performance of the on-site secondary smart devices.
