High-speed railway catenary CT power-taking device and method

Abstract

The invention discloses a high-speed railway catenary CT power-taking device and method. The high-speed railway catenary CT power-taking device comprises a CT power-taking module group, an energy storage module, a controller module and a remote communication module, wherein the CT power-taking module group is composed of multiple connected CT modules; the output ends of the modules are parallellyconnected and are then connected with the input end of the energy storage module; the controller module is connected with the CT module group, the energy storage module and the remote communication module respectively; the controller module controls on or off of a power release port of the CT module, and the power taking amount of the CT power-taking module group is adjusted; the controller modulecontrols the switch of the energy storage module to make two battery groups perform charging and discharging alternately; and when the device fails, the controller module starts the remote communication module to give an alarm.

Description

technical field [0001] The invention belongs to the technical field of special power supplies, and in particular relates to a power supply device which utilizes an alternating current CT of a high-speed railway catenary to provide a stable and reliable power supply for on-line detection equipment on the high-speed railway catenary. Background technique [0002] The distribution of high-speed railways in my country is becoming more and more extensive. The catenary is one of the core technologies of high-speed railways, but it is exposed to the natural environment and is easily affected by the environment. For the online monitoring equipment of the catenary, a stable and reliable low-voltage power supply is required. CT (Current Transformer for short) takes power, including the power-taking electromagnetic core and the power-taking coil T wound on the power-taking electromagnetic core. The catenary line passes through the magnetic core. The excitation voltage is generated at b...

AI Technical Summary

Problems solved by technology

[0009] To sum up, the CT power-taking device on the high-speed railway catenary has a short effective power-taking time, and the loop current varies greatly, which is vulnerable to the impact of extra-large current. The existing CT power-taking devices on the market cannot be used for online monitoring of the catenary. The device provides a stable and reliable low voltage power supply
