刚性悬挂接触网作为一种新型接触网悬挂方式,主要适用于隧道中轨道交通的电能传输,广泛应用于城市地铁及电气化铁路隧道之中。与传统的柔性悬挂方式相比,刚性悬挂方式因其结构简单能够节省空间,并且具有载流量大以及安装和维护简单方便等优点,降低了电气化铁路建设和未来运营及维护的成本,又被称之为免维护接触网。本文主要探讨了刚性悬挂接触网的发展现状和主要特点,以及在铁路电气化中的应用。
As a new type of catenary suspension, rigid suspension catenary is mainly applied to the transmission of electric energy in the rail transit in the tunnel and is widely used in urban subway and electrified railway tunnels. Compared with the traditional flexible suspension mode, the rigid suspension mode can save the space because of its simple structure, and has the advantages of large current carrying capacity and simple installation and maintenance, reducing the cost of electrified railway construction and future operation and maintenance, and is also called as The maintenance-free contact network. This paper mainly discusses the development status and main features of rigid suspension catenary, as well as its application in railway electrification.
