1, The principle of dc fuse:

The working principle of the fuse is a simple relationship between I2R and time. The greater the current, the shorter the fusing or opening time. The power consumption of the fuse is proportional to the square of the current through the fuse. When the power consumption is too high, the fuse blows. This feature also applies to wire harnesses protected by fuses. If the amount of heat generated exceeds the heat of distribution, the temperature of the fuse will increase, when the temperature rises to the fuse fuse melting point fuse occurs when the fuse is to open the circuit to play a protective role.

5, The main advantages of fuses

A, Good selectivity Up and down fuse fuse rated current as long as the GB and IEC standards to meet the requirements of the overcurrent ratio of 1.6: 1 requirements, that is, the upper rated fuse current is not less than the subordinate of the value of 1.6 times, as the upper and lower level Selective cut off fault current;

B, Good current limiting characteristics, high breaking capacity;

C, Relatively small size;

D, Cheaper prices.

Structural fratures

Fuse link is made of pure silver(or silver strings),welding low tin and encapsulated in the melt tbe made of high-strength porcelain, the fuse tube filled with high-purity quartz sand chemically processed as the arc medium.Fuse body is connected with contacting terminals by spot welding fuse base suppressed by the resin or plastic casing fitted with contacts and contains the fusion pieces,the connection made by riveting as the support of the appropriate size fuse body parts.This series fuse has a compact and convenient device,use security,beautiful appearance,etc.
