摘要

为确保船用变压器的质量,有必要在造船业中采用新的组织和技术解决方案。分析了俄罗斯海事船级社(Russian Maritime Register of Shipping)的要求、干式变压器的现行 ISS、相关行业企业和外国公司的经验、船舶电力推进系统电力变压器的设计特点。对船舶电力推进系统电力变压器的要求、设计和运行特点进行分析的结果已经公布。考虑并分析了工作和应急模式下变流器的主要参数。提出了确保提高船用变流器变压器可靠性的组织和技术方向。与陆地运输用换流变压器不同,目前还没有针对造船用换流变压器的规范性文件。造船业现行的规范性文件并未充分考虑船用换流变压器的特殊性。我们注意到船用转换变压器的现有主要特点。船用转换变压器发生事故时的经济损失很大,因此与陆运转换变压器相比,对其电动稳定性的要求更高。在造船业中,对变压器特性和模式分析所需的测试过程中部分短路电压和分路短路电压的确定没有要求。在制造船用变流器变压器时,有必要利用计算机建模对船用变压器的特性模式进行论证,制定测量和计算所选模式参数的方法,并对变压器-整流器系统中最可能发生的事故进行过程计算。随着船用电力推进系统功率的增加,制定国家规范性文件以确保变流器变压器的开发和运行质量变得越来越重要。

Ship electric propulsion systems transformers: specific aspects of development
The necessity of new organizational and technical solutions in shipbuilding to ensure the quality of marine transformer transformers is substantiated. The analysis of the requirements of the Russian Maritime Register of Shipping, the current ISS for dry transformers is carried out, the experience of enterprises of related industries and foreign companies, the design features of power transformers of the ship's electric propulsion system are considered. The results of the analysis of the requirements for power transformers of marine electric propulsion systems, the features of their design and operation are presented. The main parameters of the converters in operating and emergency modes are considered and analyzed. The organizational and technical directions of ensuring increased reliability of marine converter transformers are proposed. Unlike converter transformers for land transport, there are no regulatory documents for power converter transformers in shipbuilding. The regulatory documents in force in shipbuilding do not fully take into account the specifics of marine conversion transformers. The existing main features of marine converter transformers are noted. High economic losses in the event of an accident of marine converter transformers determine higher requirements for their electrodynamic stability compared with converter transformers for land transport. In shipbuilding, there are no requirements for determining the partial short-circuit voltage and the splitting short-circuit voltage during testing of transformers necessary for the analysis of their characteristics and modes. When creating marine converter transformers, it is necessary to justify the characteristic modes of marine transformers using computer modeling, develop methods for measuring and calculating the parameters of selected modes and perform process calculations for the most likely accidents in the transformer – rectifier system. With the increase in the power of shipboard electric propulsion systems, the development of state regulatory documentation to ensure the quality of development and operation of converter transformers is becoming increasingly relevant.
