A power supply specially used for a telemechanical type railway

Abstract

The invention brings forward a power supply specially used for a telemechanical type railway. The power supply comprises a box. The interior portion of the box is divided into five chambers. A high voltage side of a first transformer room is connected with a first high voltage switch room; a low voltage side of the first transformer room is connected with a first low voltage cabinet of a low voltage chamber; a high voltage side of a second transformer chamber is connected with a second high voltage switch room; a low voltage side of the second transformer chamber is connected with a second low voltage cabinet; and an intelligent telemechanical cabinet is separately connected with the first high voltage switch room, the first transformer room, the second high voltage switch room, the second transformer room, the first low voltage cabinet and the second low voltage cabinet. A backup AC and DC power supply cabinet is separately connected with the first low voltage cabinet and the second low voltage cabinet. The power supply of the invention employs a preassembled box type structure, simultaneously employs a design integrating two power supplies which are 27.5kV and 10kV, shortens the cooperation distance between the two power supplies, lowers on-site construction difficulty, realizes real time monitoring and control of dual supply operation states through the intelligent telemechanical cabinet, guarantees normal operation of the dual supply and raises the safety and reliability degrees.

Description

technical field [0001] The invention relates to a special dual power supply for railways, in particular to a telecontrol special power supply for railways, which belongs to the technical field of electrified railways. Background technique [0002] Electrified railway, also known as electrified railway, is mainly composed of two kinds of railway trains (commonly known as trains) such as electric locomotive or EMU. The railway and the locomotive itself do not have energy. Power supply, the required energy is provided by the electric traction power supply system. The traction power supply system along the line is mainly divided into two parts: traction power supply, signal and control power supply. The power supply of the substations along the line must have two power supplies, one is a 10kV line and the other is a 27.5kV line. The low-voltage power supply for signal and control needs two power supplies, one main and one backup. [0003] There are a lot of equipment along the...

AI Technical Summary

Problems solved by technology

[0004] (1) The original 10kV and 27.5kV power supplies are installed separately, and the two boxes need to be connected by secondary wiring to form a dual power supply. It is a bit difficult to cooperate with each other, and the formation of automation is more complicated. Maintenance and repair require two places to contact and run

[0005] (2) During foundation construction, two foundations need to be built, which covers a large area and increases the amount of work

[0006] (3) When the equipment is installed, it needs to be installed in two places, and on-site cables and auxiliary cables need to be installed between the two equipments, which requires on-site installation and debugging

The amount of installation work on site is relatively large, and the project cost is relatively large
