AI Technical Summary

Technical Problem

The stability and elasticity of the catenary network of electrified railways are poor under harsh conditions, resulting in unsmooth flow, troublesome maintenance, and high investment costs.

Method used

Install insulating strips and power supply strips on both sides of the track, and connect vibration sensor switches, sound sensor switches and light-controlled sensor switches in series on the outside. When the powered frame at the front and rear of the train contacts the power supply strip, the sensor switch closes and closes to realize zone control. Sectional power supply ensures smooth flow and convenient maintenance.

Benefits of technology

It realizes an electrified railway power supply system with low investment, smooth flow and easy maintenance, which reduces the operating cost and maintenance complexity of the system.

Abstract

The invention relates to an electrified railway traction power supply system which is low in investment, is smooth for obtaining a current and is convenient to maintain. Rail webs outside two steel rails of a rail are respectively provided with one insulating strip; then a power supply strip is respectively arranged outside each insulating strip; each vibration inductive switch is connected in series with a sound inductive switch and a light-operated inductive switch; one ends of the connected switches are connected to the power supply strips at one sides; the other ends of the connected switches are connected with feed lines; the power supply strips at the other sides are connected with return wires. Power receiving frames at a headstock side and a tailstock side of a train are in contact with the power supply strips; when the train passes through a zone, the vibration inductive switches are closed, the sound inductive switches are closed, the light-operated inductive switches are closed, the power supply strips in the zone supply power, the power receiving frames of the train obtain a current and the train runs; when the train runs into a next power supply zone, the next power supply section is powered on, and power supply is stopped in the power supply zone. The aims of low investment, smoothness for obtaining the current and convenience for maintenance are fulfilled.
