Description

Technical Field

[0001] The present invention relates to the technical field of emergency protection devices, and in particular to a fuse protection device, a fuse protection method and a low-voltage fuse. Background Art

[0002] As a commonly used circuit protection device, a fuse cuts off the circuit by melting its own fuse when a circuit fault such as overload or short circuit occurs, thereby protecting other devices in the circuit.

[0003] However, traditional fuses have some problems during use. When ordinary fuses are operated at a current close to their rated current for a long time, the fuse element will not melt immediately, but will gradually age due to heat. Over time, this aging may cause the fuse to melt before the rated melting current is reached, resulting in false operation. Moreover, when an abnormality is detected, the melting process cannot be controlled according to the current load conditions, and the melting operation can only be carried out in a single mode, which greatly reduces the protective effect of the fuse.

[0004] Therefore, in order to overcome the above-mentioned defects, the present invention provides a fuse protection device, method and low-voltage fuse. Summary of the Invention

[0108] At the same time, when the hidden danger overload point is a single value, the value of the hidden danger overload point is locked, and the locked value is used as the second overload state judgment indicator;

[0109] The overload status determination unit is used to:

[0110] Based on the management terminal, a duration overload threshold and a value overload threshold are respectively obtained, and the first overload state determination index and the second overload state determination index are respectively compared with the corresponding duration overload threshold and value overload threshold, and the overload type and overload degree of the current data are obtained based on the comparison results;

[0123] In this embodiment, the duration overload threshold and the value overload threshold are both set in advance, and are measurement indicators for determining whether an overload exists, and can be adjusted.

[0124] In this embodiment, the continuous overload means that the overload condition is maintained for a period of time and the time is relatively long.

[0125] In this embodiment, the representative current value refers to the result obtained by averaging the values of each potential overload point within the duration period, in order to facilitate the determination of the blowing time of the fuse.

[0126] In this embodiment, the factory specification parameters are known in advance, including the material parameters of the fuse and the temperature coefficient during use.

[0127] In this embodiment, the inverse time delay characteristic curve model is constructed based on the factory indicator parameters of the fuse, that is, it is used to analyze the time required for the fuse to blow under different current conditions. The inverse time delay characteristic curve represents the relative relationship between the blowing time and the current value when the fuse blows. The greater the current, the shorter the blowing time.
