摘　　要：介绍一种新型数字式同步指示仪,采用具有DSP功能的新一代单片机,应用数字信号处理技术计算断路器两侧电压的幅值、频率和相角,精度高,抗干扰能力强,同时能够进行电压幅值补偿和相角补偿,具有电磁式同步指示仪无法比拟的优点。A novel digital synchronization indicator is introduced, which adopts a high performance CPU with DSP function. The digital signal processing technology is used to calculate voltages and frequencies of the different sides of the circuit breaker and the phase angle between them. It is accurate and disturbance-compatible. It also has the functions of amplitude compensation and angle compensation.
