The temperature change is adjusted to meet the test requirements by controlling the current size. However, the existing hydrogen-based furnace reaction chamber heating device still has shortcomings. Specifically, the resistance wire used in the existing reaction chamber heating device is replaced with resistance wire with different needs due to different tests. The insulation medium of the resistance wire needs to be checked and replaced for each test. High temperature can easily affect the service life of conductive accessories such as resistance wire, terminal blocks, and tungsten steel rods. In addition, accidental touch and other phenomena are prone to occur during the installation process, resulting in resistance wire breakage, which makes the device cost and economic loss high. At the same time, the resistance heating device adopts multiple groups of resistance wires connected in parallel, and the number of external terminals is large.
