Description
Technical Field
The utility model relates to an electronic railway, in particular to be used for anchor's stay wire under contact net additional wire.
Background
The additional lead is an important component of the electrified railway, is generally erected along the same pole of a line and a contact network lead, and is divided into a plurality of sections with certain lengths and independent of each other in order to meet the requirements of power supply and mechanical stress, and the tail end of each section is generally anchored on a contact network strut. Because the additional leads are all arranged with tension, a certain additional bending moment can be brought to the strut at the lower anchor part, so that the load borne by the strut is increased, in order to offset the bending moment applied by the additional leads on the contact net strut and reduce the load on the strut and the strut foundation, a lower anchor stay wire is generally arranged at the lower anchor strut to achieve the effect of stress balance of the strut, and the stay wire material usually adopts a zinc-5% aluminum-mixed rare earth alloy plating steel strand (GB/T20492-.
The additional lead is the same as the contact net lead and is a charged body in a working state, when the additional lead has the function of return grounding, the additional lead is generally suspended between the additional lead and the contact net support in an uninsulated mounting mode, namely when the contact net support adopts a steel column type, the steel column can be used as a part of the return grounding, and the current on the additional lead can flow into the ground through the contact net steel column. However, the traditional lower anchor stay at the lower anchor strut of the additional lead is also connected with the ground, so that a current loop is easily formed among the steel column of the contact network, the lower anchor stay and the ground, and the lower anchor stay and the steel column of the contact network can be electrically corroded for a long time.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an anchor is acted as go-between under taking the insulator for additional wire is provided to effectively avoid steel column, earth and act as go-between to form the electric current loop, reduce and act as go-between by the scaling loss risk, improve railway operation safety.
The utility model discloses an additional wire is with taking anchor acting as go-between under insulator, including acting as go-between, taut insulator and relevant connection spare part, characterized by: the stay wire consists of a lower section stay wire and an upper section stay wire; the top of the upper section of the stay wire is connected with a wedge-shaped strain clamp, and the wedge-shaped strain clamp is connected with a lower anchor stay wire base on the steel column body; the bottom of the lower segment of the stay wire is connected with an NUT type adjustable strain clamp, the NUT type adjustable strain clamp is connected with a lower anchor stay wire hanging plate, and the lower anchor stay wire hanging plate is connected with a stay wire foundation; the upper end of the lower section of stay wire is connected with the lower end of the upper section of stay wire in a ring-shaped buckling manner, and a tensioning insulator is arranged between the contact surfaces of the lower section of stay wire and the upper section of stay wire.
The utility model has the advantages that the current loop formed among the steel column, the ground and the stay wire is effectively avoided, the risk of burning of the stay wire is reduced, and the railway operation safety is ensured; reasonable structure and simple construction.
