SAFETY FUSE FOR EXTENDING THE TIME CONTINUENCE OF ELECTRIC BULBS WITH WOLPHARM FIBERS

摘要

The safety fuse is composed from electronic regulated structures with triac (?) and meltable glass safety fuse. Both these integral parts appear as a whole by shape and length is suitable to the insertion of standard ceramics of meltable installation safety fuse type D (JUS N.E5.005/1962. It is installed on the board with the safety fuses instead of meltable ceramics insertion which protects the circuit of electrical bulbs. Reducing effective voltage on bulbs for 15% which extends the life of the bulbs about ten times.
