高压喷射式熔断器的温升试验与仿真验证

The Temperature Rise Test and Simulation Verification of High Expulsion Fuse

由于高压喷射式熔断器是靠发热元件熔体来开断电路的,其发热计算对于熔断器的研发设计和性能改进都具有重要的意义。高压喷射式熔断器各部分的温升是兼具发热和散热的一个复杂过程,很难建立一个能考虑所有影响因素的解析公式,通过高压喷射式熔断器的温升试验和仿真研究,验证了各部分的温升特点及温升值最高点。

As the high--pressure jet fuse is by the heating element melt to break the circuit,the heat calculation for the fuse design and performance improvements are of great significance. The temperature rise of each part of a high pressure jet fuse is a complex process of heating and heat dissipation. It is difficult to establish an analytical formula which can take into account all the factors. In this paper,the temperature rise test and simulation of high pressure jet fuses are used to verify the temperature rise characteristics and the highest value of temperature rise.
