An intelligent early warning fuse

Abstract

The invention relates to the technical field of fuses, in particular to an intelligent early warning fuse and a method for preparing a fusible core of the early warning fuse. The fuse is monitored andearly warned by monitoring multiple parameters simultaneously, and thus workers are helped to make relevant preparation work in advance. A housing is detachably arranged, the fusible core and an electrode are detachably arranged, the fuse can be continuously used only by replacing the fusible core, and the use cost is saved. In addition, different specifications of fusible cores are stored by forming storage grooves, and the use flexibility of the fuse is also improved. By detachably combining a ceramic material and a transparent plastic, the high temperature resisting characteristic and reliability of the fuse can be also ensured while the weight of the housing is lightened. According to the method for preparing the fusible core of the early warning fuse, workers can conveniently pay close attention to the working temperature of fuses by coating multiple coating sections and observing color change of temperature layers in real time, and thus advanced adjustment is made.

Description

technical field [0001] The invention relates to the technical field of fuses, in particular to an intelligent early warning 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. , will also bring a lot of inconvenience. Although some fuses in th...

[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 after the event, but it is impossible to warn the 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. , will also bring a lot of inconvenience

Although some fuses in the prior art use color-changing pigments on fuses, such as the patent document CN102598189B, which only uses the color-changing characteristics of pigments to judge the location of fuse melting points, it is still unable to complete early warning of fuse blowing and use color changes. early warning

Moreover, the temperature-indicating paint is an irreversible paint, which can only be used to determine the melting point by changing the color when the fuse is blown, but cannot give an early warning before the fuse is blown. The preparation process is relatively complicated, which affects production efficiency

[0003] The existing fuse housings are generally plastic or ceramic housings. Although the ceramic housing is resistant to high temperatures, it is bulky. Although the plastic housing is light, it is not resistant to high temperatures. There is a greater safety hazard during long-term use. There is also a portable and safe fuse on the market

[0004] 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 in accidents, but also For production departments such as factories, it will also affect production efficiency, so the fuse also has the defect of not being smart enough and convenient, and affecting the economic benefits of the factory.
