摘要
输电线路和电气化铁路(以下简称“电铁”)接触网的覆冰会带来诸多安全隐患,严重情况下会引起重大事故和经济损失。目前解决输电线路和电铁接触网的覆冰问题主要采用交直流融冰方式。从交直流融冰原理出发,介绍交直流电热融冰技术的电路实现与基本原理,并对两种应用场景进行比较,深入讨论交直流融冰技术的优势与其缺点所在,并给出相关改进措施。结合交直流融冰的配置原则和实际的应用案例,介绍在实际应用中交直流融冰装置的运营效果,并对其运营环境与条件进行分析,研究交直流融冰装置的结构和配置,对相关技术与设备配置原则提出建议。
The icing of transmission line and electric railway catenary brings lots of hidden safety hazard,which will cause major accidents and economic losses in serious cases.At present,AC/DC ice melting technology is mainly used to solve the icing problem of transmission lines and electric railway catenary.Starting from the principle of AC/DC ice melting,the circuit implementation and basic principle of AC/DC electric ice melting technology were introduced,two application scenarios were compared,advantages and disadvantages of AC/DC ice melting technology were discussed,and relevant improvement measures were given.Combined with the configuration principle of AC/DC ice melting and practical application cases,the operation condition of AC/DC ice melting device was introduced in practical application,its operation environment was analyzed,the structure and configuration of AC/DC ice melting device were studied,and suggestions on the configuration principle of mentioned technology and equipment were put forward.
