【摘要】：電觸點(diǎn)材料是影響電氣與電子工程中電接觸可靠性的關(guān)鍵。本文綜合應(yīng)用了激勵電流斷續(xù)斬波技術(shù)、低噪低漂移弱信號調(diào)理技術(shù)和滑動窗口平均濾波技術(shù),設(shè)計(jì)并實(shí)現(xiàn)了接觸電阻的高精密測量,進(jìn)而應(yīng)用0.01級標(biāo)準(zhǔn)電阻和M22等級標(biāo)準(zhǔn)砝碼完成了測量系統(tǒng)的誤差分析。最后以典型平面AgCdO復(fù)合觸點(diǎn)材料完成了不同激勵電流條件下接觸電阻與接觸壓力間滯回特性的測試與分析,實(shí)驗(yàn)結(jié)果確定了接觸壓力和激勵電流對接觸電阻的影響規(guī)律。
[Abstract]:The electrical contact material is the key to affect the reliability of electrical contact in electrical and electronic engineering. In this paper, the technology of intermittent chopping of exciting current, low noise and low drift, weak signal conditioning and sliding window average filtering are used in this paper. The high precision measurement of contact resistance is designed and realized. The error analysis of the measurement system is completed by using the standard resistor of class 0.01 and the standard weight of grade M22. Finally, the hysteretic characteristic between contact resistance and contact pressure under different excitation current conditions is accomplished by using typical planar AgCdO composite contact material. Sex testing and analysis, The effect of contact pressure and excitation current on contact resistance is determined.
