一、国产12伏18安正极内接地调节器上1欧姆,30欧姆,80欧姆电阻易烧毁的原因: 30、80欧姆二只电阻线径较细,只有φ0.1毫米,由于以往材料是X15H60镍铬铁合金丝,强度差,加之大气耐它的腐蚀和工艺上存在灼一些问题,影响了30、80欧姆电阻的质量。现在材料采用国产Cr20Ni80镍铬合金丝,强度及耐腐蚀能力均有提高,并改进了绕制铆接工艺,这样这两只电阻毁坏 First, the domestic 12 volt 18 amp internal ground regulator 1 ohm, 30 ohm, 80 ohm resistance easy to burn reasons: 30,80 ohm two resistance smaller diameter, only φ0.1 mm, because the material is X15H60 Nickel-chromium-iron alloy wire, poor strength, combined with atmospheric corrosion and corrosion of its processes there are some problems burning, affecting the quality of 30,80 ohm resistance. Now the material using domestic Cr20Ni80 Ni-Cr alloy wire, strength and corrosion resistance have improved, and improved winding riveting process, so that the two resistors destroyed
