熱的主要原因是觸點(diǎn)壓力不夠、表面氧化或不清潔和容量不夠;觸點(diǎn)熔焊的主要原因是觸點(diǎn)在閉合時(shí)產(chǎn)生較大電弧,及觸點(diǎn)嚴(yán)重跳動(dòng)所致。 檢查觸點(diǎn)表面氧化情況和有無污垢。觸點(diǎn)有污垢,已用汽油清洗干凈。銀觸點(diǎn)的氧化層不僅有良好的導(dǎo)電性能,而且在使用中還會(huì)還原成金屬銀,所以可不作修理。銅質(zhì)觸點(diǎn)如有氧化層,可用油光銼銼平或用小刀輕輕地刮去其表面的氧化層。
觀察觸點(diǎn)表面有無灼傷燒毛,銅觸點(diǎn)燒毛可用油光銼或小刀整修毛。整修觸點(diǎn)表面不分光滑,不允許用砂布來整修,以免殘留砂粒在觸點(diǎn)閉合時(shí)嵌在觸點(diǎn)上造成不良。但銀觸點(diǎn)燒毛可不必整修。觸點(diǎn)如有熔焊,應(yīng)更換觸點(diǎn)。若因觸點(diǎn)容量不夠而造成,更換時(shí)應(yīng)選容量大一級(jí)的電器。檢查觸點(diǎn)有無松動(dòng),如有應(yīng)加以緊固,以防觸點(diǎn)跳動(dòng)。檢查觸點(diǎn)有無機(jī)械損傷使彈簧變形,造成觸點(diǎn)壓力不夠。若有,應(yīng)壓力,使觸點(diǎn)良好
