METHOD FOR DETECTING FUSE STATUS OF HIGH-CURRENT RECTIFIER DEVICE

摘要

The present invention relates to a method for detecting the fuse status of a high-current rectifier device; the method achieves the objective of fuse status detection via simultaneously detecting normally open nodes and normally closed nodes of the fuse using scanning method; a scan line scans the common end of an auxiliary node of the fuse arm by arm in units of rectifier arms; the normally open nodes of each fuse on the rectifier arm are connected with the recoil lines of the normally open nodes, and the normally closed nodes of each fuse are connected with the recoil lines of the normally closed nodes; the normally open nodes and normally closed nodes of fuses of each rectifier arm respectively share one recoil line, wherein the normally open nodes and normally closed nodes are at the same physical location. The beneficial effects of the present invention are: improving the accuracy of fuse status detection in strong magnetic field and high vibration of the high-current rectifier valve cabinet, reducing the cable volume within the rectifier cabinet, greatly saving manufacturing costs; reducing the complexity of the device, improving anti-interference capability of the device, and enabling the device to run more reliably.
