High speed railway earthquake early warning system traction power supply system overhead line system power off interface device

Abstract

A high speed railway earthquake early warning system traction power supply system overhead line system power off interface device relates to the overhead line system technology, and comprises a disposal signal reception module, a relay group module and an isolation module; the disposal signal reception module is used for receiving external signals, and outputting same to the relay group module; the relay group module comprises a normally open contact combined circuit and a normally closed contact combined circuit; the output end of the disposal signal reception module is connected with a controlled end of the normally open contact combined circuit and a control end of the normally closed contact combined circuit. The automatic power off emergency disposal purpose of the high speed railwayearthquake early warning monitoring system can be realized with a high reliability.

Description

technical field [0001] The present invention relates to catenary technology. Background technique [0002] my country is located between the two major earthquake belts in the world—the circum-Pacific seismic belt and the Eurasian seismic belt. It is a country with severe earthquake disasters. Historical earthquake damage records show that the impact of earthquakes on the safety of my country's railway operations cannot be ignored, especially today when train speeds are increasing day by day. In recent years, my country's high-speed railway has attached great importance to this issue, and has carried out a series of related researches, and successively set up earthquake monitoring and alarm systems on Beijing-Tianjin Intercity Railway, Beijing-Shanghai High-speed Railway, Harbin-Dalian Passenger Train and other railways, but these systems only realized Earthquake monitoring and earthquake alarm functions do not have the ability to deal with earthquake linkage emergency, and c...
