摘要： The present invention relates to a fast bypass device (1), comprising a pair of reverse-parallel-connected thyristors (T1, T2), a lightning arrester (SA) and a backup protection switch (BPS), wherein the pair of reverse-parallel-connected thyristors (T1, T2), the lightning arrester (SA) and the backup protection switch (BPS) are connected in parallel with each other. The advantages of the present invention are: 1) it does not require the additional provision of a pair of thyristors and complementary electronic drive circuit, thereby reducing costs; 2) it operates in a passive way, and is not restricted by whether or not the power supply is working normally; 3) since the backup protection switch is capable of closing within 1 millisecond of a fault occurring, and the load through the lightning arrester before closing is limited, faster and more reliable protection of the main capacitor can be realized; moreover, a lower load allows a smaller lightning arrester to be selected for use, saving space and further reducing costs.
