Rigid-flexible combined contact net system for non-upper cover field section

Abstract

The invention provides a rigid-flexible combined catenary system for a non-overlying field section. Flexible suspension catenaries are arranged on an access line and a throat area of the field section, rigid suspension catenaries are arranged in a garage, and movable catenaries are arranged between the access line of the field section and the throat area and between the throat area and the garage. According to the internal and external installation conditions of the non-upper-cover field section garage, a design method of erecting different types of overhead contact systems in different areas is adopted, flexible suspension overhead contact systems are arranged on an access line and a throat area of the field section, rigid suspension overhead contact systems are arranged in the garage, and movable overhead contact systems are arranged between the access line and the throat area and between the throat area and the garage, so the passing height limitation on emergency repair and fire fighting vehicles is relieved, and the passing requirements of the emergency repair and fire fighting vehicles in emergency situations are met.

Description

technical field [0001] The invention belongs to the field of rail transportation, and particularly relates to a rigid-flexible combined catenary system for a non-covering field section. Background technique [0002] In the urban rail transit field, the catenary is generally used to supply electricity to the electric locomotive through contact with the on-board pantograph. At present, the catenary design scheme commonly used in the non-superstructure section at home and abroad is mainly flexible suspension catenary, and only a few strands use rigid suspension catenary due to maintenance reasons. In the existing non-covered yard section, overhead flexible catenary is generally used inside and outside the warehouse, which requires high installation of civil structures; the height of the catenary in front of the warehouse and at the intersection will make it difficult for emergency rescue and fire-fighting vehicles to pass through in an emergency. Create an emergency safety ris...
