我厂有75kvA和100kVA盐浴炉各一台,在使用过程中,发现盐浴炉电极柄与变压器连接不良,在大修这两台盐浴炉时,我们采用了复铜电极柄,其连接效果大大改善。改造前,盐浴炉电极柄用A3钢,与变压器间的过渡连接为紫铜板。由于A3钢的表面接触电阻比较大,工作过程中在此连接处形成一个发热区,结果造成温度升高,A3 I plant a 75kvA and 100kVA salt bath furnace each one, during use, found salt bath furnace electrode handle and transformer bad connection, overhaul the two salt bath furnace, we use the complex copper electrode handle, the connection effect Greatly improved. Before the transformation, salt bath furnace electrode handle with A3 steel, and the transition between the transformer for the copper plate. As A3 steel surface contact resistance is relatively large, the process of forming a junction in the heating zone, resulting in the temperature rise, A3
