Termiese beskermer

Daarna, die spanning tussen die kontakte van die termiese afsnypunt en die GS-kring styg om te verseker dat die GS-kring ontkoppel word. Deur die huidige uitvinding, die probleem dat die termiese afsnypunt in die GS-stroombaan nie die stroombaan effektief kan afsny nie, is opgelos, en die effek van die verbetering van die kringveiligheid word bereik.

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. Op hierdie manier, the circuit is permanently cut off.
