摘要:In recent years, my country’s high-tech technology has shown an unstoppable development trend, which has promoted the application of electrical equipment in the domestic shipbuilding industry. Energy conservation and environmental protection have gradually become the theme of the times. Ships need to pay attention to the application of energy-saving technology when applying electrical equipment to ensure that ships can play a practical role in green and environmental protection. This article focuses on the problem that the power consumption of marine auxiliary machinery greatly affects the endurance, and elaborates the energy-saving technology of marine auxiliary electrical equipment in detail, and analyses the energy-saving effect it can bring, and finally the application prospects of the marine auxiliary energy-saving technology the outlook was carried out.
