Structural Classification Of Thermal Fuse
organic type metal shell temperature fuse is a combination, the composition of the structure are:
1. Pin (A), 2. Sealed resin, 3. Insulating ceramic, 4. Fine spring, 5. Star reed, 6. Coarse spring, 7. wafer, 8. temperature sensing block, 9. The housing, 10 Pin (B).
When the temperature insurance is in normal operation, the current flows from the left lead to the sliding contact and flows through the metal housing to the right lead. When the external temperature reaches the predetermined temperature, organic matter can melt melt, the compression spring will become loose. That is, spring expansion, sliding contact (slidingcontact) and the left side of the separation. The circuit will cut off, the current between the sliding contact and the left lead is cut off. the temperature fuse will fail and can not be used again.
2, easy to melt alloy wire thermal fuse has ceramic shell and square shell, its temperature sensing element is a fusible gold.
Product structure: is the axis of the symmetrical lead, fusible alloy wire, and resin mixture and insulated porcelain tube, plastic shell.
When the temperature rise of the heating element is set to a temperature, the resin mixture begins to liquefy, when the melting point is reached, with the help of the resin mixture (increasing the surface tension of the melted alloy), has been molten alloy wire in the resin mixture under the action of tension, quickly to both ends of the wire as the center shrink into a spherical, and thus permanently cut off the circuit.
Technical Parameters And terminology Of Thermal Fuses
(1) Rated operating temperature (Tf):
The temperature fuse is tested according to the standard method to change the temperature of its conductive state. According to IEC6091 standards-based security provisions, the temperature fuse must be operated within the rated operating temperature + 0 / -10 C (the Japan Electrical Supplies Act provides a tolerance range of ± 7 C).
(2) Operating temperature Found:
The temperature fuse is heated in the silicone oil tank at a rate of 0.5-1 C per minute, detection current is less than the fusing temperature measured at 10mA condition. It is the actual operating temperature of the temperature fuse.
(3) Holding temperature (Th):
When the temperature fuse passes the rated current, can hold for 168 hours without changing the maximum temperature of its conductive state.
(4) limit temperature (Tm):
Temperature fuse can withstand the maximum temperature for 10 minutes reconnection phenomenon never occurs.
(5) Rated current (Ir):
The maximum current that the temperature fuse can carry.
(6) Rated voltage (Ur):
Temperature fuse maximum operating voltage.
