Fast Fuse: quick fuse is mainly used for short-circuit protection semiconductor rectifier elements or fairing. Due to overload of the semiconductor element is very low. In a very short time only withstand overcurrent Hefei large high-voltage fuse, short circuit protection and therefore require the ability to quickly blown. Enclosed structures and filler fast fuse fuse is basically the same Yiyang high-voltage fuse, but the melt material and shape is different, it is a silver piece punched in a change in the V-shaped cross-section melt deep grooves. An understanding of the characteristics of seconds, we can see from the Joule's law Q = I2 * R * T, series circuit, the fuse is essentially the same R-value, the heat made proportional to the square of the current I, and fever T proportional, ie: when the time high-voltage fuses, fuse current required to melt large Ganzhou is short. And when the current is small, the time required to melt the fuse is longer, even if the heat accumulation rate is less than the thermal diffusion rate, the temperature does not rise to the melting point of the fuse, the fuse will not even blown. So, in a certain overload current range fuse, when the current returns to normal, the fuse is not blown, can continue to be used. Changsha high-voltage fuses, fuse, power is supplied by the Xi'an Huayi Huayi power plant. Xian Huayi power plant (www.xahy.com) strong, credible, in Xi'an high-voltage circuit breakers and other industry has accumulated a large number of loyal customers.
