[0002] As a commonly used circuit protection device, the fuse cuts off the circuit by melting its own fuse when the circuit is overloaded, short-circuited or other faults occur, thereby protecting other devices in the circuit. However, there are some problems with traditional fuses during use. When ordinary fuses are operated at a current close to their rated current for a long time, the fuse element will not blow immediately, but will gradually age due to heat. As time goes by, this aging may cause the fuse to blow before the rated fuse current is reached, thereby causing false operation. When an abnormality is found, the fuse cannot be controlled differently according to the current load conditions, and can only be operated in a single mode, which greatly reduces the protection effect of the fuse.

A method for protecting a fuse, characterized in that: include: Step 1: Monitor the current data flowing through the fuse based on the sensor, and transmit the monitored current data to the main control center; Step 2: Analyze the current data based on the main control center, determine the overload state of the current data, and determine the fuse breaking time based on the overload state; Step 3: Control the fuse to perform a blowing process based on the blowing time, and simultaneously perform current limiting control on the current flowing through the fuse during the blowing process.

9. A low voltage fuse having a computer program stored thereon, characterized in that: When the computer program is executed by a processor, the steps of the protection device of a fuse as claimed in any one of claims 1 to 7 are implemented.
