Problems solved by technology

[0006] The existing fuses on the market have only one fuse. In the case of damaged use or when the load power increases, it can only be replaced by replacing the entire fuse or fuses of other specifications. This is not only inconvenient

Abstract

The invention relates to the technical field of fuses, specifically to a reversible temperature-indicating paint and a preparation method thereof, and a fusible fuse core and a fuse. The intelligent early-warning fuse provided by the invention has the following advantages: the fuse is simultaneously monitored and warned through monitoring of a plurality of parameters, so a worker is helped to do relative preparation work in advance; through detachable arrangement of a shell, a fusible core and an electrode, the intelligent early-warning fuse can be continuously used by replacement of the fusecore, so the cost of usage is saved; meanwhile, a storage groove is arranged to store fusible cores with different sizes, so the use flexibility of the fuse is improved; and through detachable combination of a ceramic material and transparent plastic, the weight of the shell is reduced, and high-temperature resistance and reliability of the shell can be guaranteed. The preparation method for the fusible fuse core provided by the invention has the following advantages: through coating of a temperature-indicating layer, a worker can conveniently observe color changes and pays attention to the working temperature of the fuse in real time, so adjustment is realized in advance.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a reversible temperature-indicating paint and a preparation method, a fuse fuse core and a fuse. Background technique [0002] Existing fuses are unable to monitor the operating temperature, operating current and other parameters of the fuse in time. Generally, only when the fuse current or fuse temperature reaches a certain level and the fuse core is blown, can it be known that there is an abnormality in the operation of the electrical equipment. The fuse can only be replaced afterwards, but it is impossible to warn relevant personnel in time in advance to prepare for prevention. Especially for special power-consuming departments such as production workshops, short-term power outages will bring great economic losses to them. For families, it is only possible to prevent power outages by replacing fuses or reducing the number of electrical equipment running at the same time. ...
