Common problems with refrigeration compressors (11)

Why can’t the compressor operate under “vacuum conditions”?
The so-called “vacuum conditions” are not absolute vacuum conditions, but extremely low pressure conditions. Gas molecules will ionize under extremely low pressure.
According to actual experimental results, the breakdown voltage of the compressor terminal is the lowest when the internal pressure of the compressor is around 3.5mmHg. When the compressor is powered on, it is easy to break down and accumulate carbon inside, which will damage the insulation of the sealed terminal. In severe cases, the sealed terminal of the compressor will burn out during operation. Therefore, it is necessary to avoid powering on the compressor when it is in a vacuum state.
