摘要

断路器处于长期运行状态

梅花触头会出现松动

导致接触电阻增大

引起触头发热

带来严重的安全隐患。记忆合金是一种随温度变化能自动产生形变的新材料

笔者将记忆合金制成的弹簧运用于梅花触头以达到降低接触电阻

减少触头发热的目的。通过对普通弹簧和记忆合金弹簧进行温度与弹簧拉力对比试验

及对应用的2种弹簧梅花触头进行了大电流温升对比试验。试验结果表明:记忆合金弹簧能够有效降低触头接触电阻和减少发热

具有广泛应用前景。

Abstract

As circuit breaker operates in a long-term state

the clubs contacts will be loosening.As a result

the contact resistance has been increased as well as the heating of the contact

which will lead to serious security problem.Memory alloy is a new material whose shape can be changed with the temperature.The clubs contacts are able to decrease resistance and contact heating with memory alloy spring.A comparative test on the tension of springs under different temperature between normal spring and memory alloy spring has been conducted.Also

the heavy current temperature rise experi ment on the clubs contacts which used normal spring and memory alloy spring has been conducted.The test results show that the memory alloy springs can reduce the contact resistance and heating effectively.Therefore

the memory alloy spring may have a broad application prospects in the future.
