通过试验证实用压缩机直接抽真空会造成压缩机内部接线柱的起弧熔化,从而导致压缩机损坏,特别是高效压缩机体积小且排气快,因此损坏更快。指出不同接线柱的抗击穿能力不同,好的结构设计其抗真空能力更强。 Through the test confirmed that the direct vacuum with the compressor will cause the compressor internal arcing start melting, resulting in compressor damage, especially efficient compressor is small and exhaust fast, so damage faster. Pointed out that the different anti-penetration ability of different terminals, good structural design of its anti-vacuum capability.
