1. The features of the high quality fuse cut out 35kv polymer or drop out fuse cutout
The fuse cutout is a type of overcurrent protector, mainly composed of parts such as melt and fuse tube, as well as external fillers. When the current of the protected circuit exceeds the specified value, the heat generated by the melt itself fuses the melt, causing the circuit to disconnect and thus providing protection. An electrical appliance that uses the heat generated by itself to fuse the melt and disconnect the circuit.
The rated current of the fuse's melt is not equal to the rated current of the fuse. The rated current of the melt is selected based on the load current of the protected equipment. The rated current of the fuse should be greater than the rated current of the melt and determined in coordination with the main electrical appliance. The fuse is mainly composed of three parts: the melt, the shell, and the support, among which the melt is a key component that controls the fusing characteristics. The material, size, and shape of the melt determine the fusing characteristics. Melt materials are divided into two categories: low melting point and high melting point. A fuse has an 'ampere second characteristic', which is simply understood as the time required for the melt to fuse is shorter when the current is high. When the current is low, the time required for the melt to fuse is longer.
Even if the rate of heat accumulation is less than the rate of heat diffusion, the temperature of the fuse will not rise to the melting point, and the fuse will not even blow. So, within a certain overload current range, when the current returns to normal, the fuse will not blow and can continue to be used.
