The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.
As shown in fig. 1, the present embodiment provides a ceramic case resistor with temperature protection, which includes a temperature fuse 1, a resistance unit 2, a filler 3, and a ceramic case 4. The ceramic shell 4 is a box body with an opening at the upper end, and the temperature fuse 1 and the resistance unit 2 are both encapsulated and fixed in the ceramic shell 4 through the filling material 3.
Three wire outlet holes 9 are arranged on the ceramic shell 4, two of the three wire outlet holes are arranged at the left end of the ceramic shell 4, and the other one is arranged at the right end of the ceramic shell 4, and the wire outlet holes 9 in the embodiment are grooves at the edge of the box body. The two ends of the thermal fuse 1 are respectively connected with a first lead 5 and a second lead 6. The two ends of the resistance unit 2 are connected with a third lead 7 and a fourth lead 8 respectively. After the temperature fuse 1 and the resistance unit 2 are fixed in the ceramic shell 4 by filling materials 3 in an embedding manner, a first lead 5 and a third lead 7 which are positioned at the left ends of the temperature fuse 1 and the resistance unit 2 respectively pass through two wire outlet holes 9 at the left end of the ceramic shell 4, a second lead 6 and a fourth lead 8 which are positioned at the right ends of the temperature fuse 1 and the resistance unit 2 are connected in the ceramic shell 4 by spot welding, and then the fourth lead 8 passes through the single wire outlet hole 9 at the right end.
The resistance unit 2 includes a resistance wire 21, a porcelain rod 22, and a cap 23. The resistance wire 21 is wound around the porcelain rod 22, and two caps 23 are respectively installed at both ends of the porcelain rod 22 and fasten the ends of the resistance wire 21. The third lead 7 and the fourth lead 8 are respectively soldered with two caps 23.

The working principle of the embodiment is as follows:
in the embodiment, the thermal fuse 1 can simultaneously realize two kinds of fault protection for the electrical system where the thermal fuse is located. In the first fault, when the system is poor in heat dissipation, the temperature in the system rises, and when a preset value is reached, the temperature fuse 1 is automatically broken and disconnected, and the system gives an alarm. The structure is characterized in that the first lead 5 and the fourth lead 8 are connected to an external alarm switch, and when the temperature fuse 1 is disconnected, the alarm is triggered. Due to the adoption of a pure physical structure, the temperature sensor has higher stability and reliability than the traditional temperature sensor, and has no transmission delay.
