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

Abstract

The invention discloses a high-speed railway catenary CT power-taking device and method, comprising a CT power-taking module group, an energy storage module, a controller module and a remote communication module; the CT power-taking module group is connected by a plurality of CT modules. The output terminals of each module are connected in parallel to the input terminals of the energy storage module, and the controller module is respectively connected to the CT module group, the energy storage module and the remote communication module; the controller module controls the on-off of the electric energy discharge port of the CT module, adjust The power taken by the CT power module group; the controller module controls the switch of the energy storage module to charge and discharge the two battery groups in turn; the controller module starts the remote communication module to alarm when the device fails.

Description

technical field [0001] The invention belongs to the technical field of special power supplies, and in particular relates to a power supply device utilizing alternating current CT of a high-speed railway catenary to obtain power, which provides 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 getting wider and wider. The catenary is one of the core technologies of the high-speed railway, but it is exposed to the natural environment and is easily affected by the environment. A stable and reliable low-voltage power supply is required for the online monitoring equipment of the catenary. CT (Current Transformer for short) takes electricity, including the electromagnetic core and the coil T wound on the electromagnetic core. The catenary line passes through the electromagnetic core. When alternating current passes through the catenary line, th...
