Abstract

The invention discloses a fast acting fuse-based detection and positioning device and a method thereof. The fast acting fuse-based detection and positioning device comprises a power supply conversion module, a fast acting fuse node signal detection module, a logic processing unit, a fast acting fuse fault alarm and trip signal output module, and a communication module; the input of the power supply conversion module is connected with an external direct-current power supply, and the output of the power supply conversion module is connected with the logic processing unit; the input end of the fast acting fuse node signal detection module is connected with a fast acting fuse node signal; the output end of the node signal detection module is connected with the logic processing unit; the logic processing unit is connected with the fast acting fuse fault alarm and trip signal output module and outputs a fast acting fuse fault alarm or trip signal; and the communication module is connected with the logic processing unit, communicates with the external and transfers fault positioning information. The invention has the advantages that: the fast acting fuse-based detection and positioning device has a simple structure, and can acquire the fast acting fuse node signal in a large-power eliminator supply; and the fast acting fuse fault information can be positioned by communication transmission and the like.

Description

technical field [0001] The invention relates to a detection and positioning device and method applied to power electronic devices, in particular to a device and method for detecting and locating the working state of a fast fuse used in a low-voltage high-current rectifying power supply. Background technique [0002] For large power electronic devices, when the circuit fails or is abnormal, the current will continue to rise, and the rising current may damage the thyristor or diode in the high-power rectifier power supply, and may also burn the circuit or cause a fire. At this time, the fast fuse placed in the circuit will fuse itself to cut off the current when the fault current rises to a certain height, thereby protecting the safe operation of the circuit. [0003] In many high-power power supply devices, it is required to be able to detect the working state of the fast fuse and locate the fault point. At present, there is no technical solution for detecting and locating t...
