低熔焊力CuCrTe真空触头材料的研制
摘要
用粉末冶金烧结工艺制备了CuCrTe低熔焊力真空触头材料
研究了Te含量对材料抗拉强度的影响。实验表明:在CuCr50材料中加入Te>0.025%时
其抗拉强度可从288MPa降低到120MPa以下
从而大大改善其抗熔焊性能。该材料已成功应用在10kV/630A真空负荷开关中。
Abstract
The CuCrTe contact material is made with powder melting technology. The effect of Te content in CuCrTe on welding strength is studied. It shows that when Te Content in CuCr50 is greater than 0. 025%
the welding strength will reduce from 288MPa to 120MPa
so that the anti-welding capability of contact material is improved. This kind of CuCrTe contact material has been used in vacuum switches.
