Termiline kaitse

The melt material used in LEAO, VÄRVI, Panasonic, SWC thermal fuses plays a vital role in the performance of thermal fuses and is one of the core components of the entire device. According to the characteristics of the melt material, we can divide them into two categories: low melting point and high melting point.

Subsequently, the voltage between the contacts of the thermal cutoff and the DC circuit rises to ensure that the DC circuit is disconnected. Through the present invention, the problem that the thermal cutoff in the DC circuit cannot effectively cut off the circuit is solved, and the effect of improving the circuit safety is achieved.

A piece of fusible alloy wire is connected between the two pins of the thermal fuse, which is covered by a special transparent resin square shell. Current can flow from one pin to another. When the temperature around the thermal fuse rises to its set operating temperature, its fusible alloy wire melts and shrinks into a spherical shape, and is attached to the ends of the two pins with the help of surface tension and special resin. Sel viisil, the circuit is permanently cut off.

SET / istu maha / RY / Uchibashi Soojuskaitse on termokaitseseade, mis on mõeldud elektroonikaseadmetele ülekuumenemiskaitse tagamiseks. Sellel on torukujuline struktuur, ja spiraalselt sulav materjal on sulam, millel on kiire sulamise omadused. Selle kaitsme mudel on BF216, mis on väikese suurusega ja sobib erinevatele elektroonikaseadmetele.
