Description
Technical field
The invention belongs to technical field of alloy, be specifically related to a kind of high temperature resistant resistance steel alloy.
Background technology
Thermistor is a kind of semiconductor resistor with temperature sensitivity, once exceed certain temperature, its resistance value along with the rising of temperature be almost increasing in phase step type, can current surge excessive, when temperature is too high, circuit is shielded.
Under working current; the heat produced and the heat that distributes reach equalizing current can be normal through; when super-high-current passes through; element produces a large amount of heats and can not distribute timely, causes resistance to rise rapidly, limits big current and passes through; thus play overcurrent protection; but along with social progress, the resistance element that emerging electric installation needs more smart temperature to control and regulate, must improve the temperature coefficient of resistance upper limit of resistance wire.
