Integrated type current transformer device

Abstract

The invention discloses an integrated type current transformer device. The device comprises a cabinet body. The cabinet body comprises a first cavity body, a second cavity body and a third cavity body, which are successively horizontally arranged. A traction current transformer module and an auxiliary current transformer module are arranged in the first cavity body. A power unit module is arranged in the third cavity body. A water cooling module used for cooling modules in the first cavity body and a wind cooling module used for cooling the module in the third cavity body are arranged in the second cavity body. The device is advantaged by proper design, compact layout, high integration level and high heat dissipation efficiency.

Description

technical field [0001] The invention mainly relates to the field of rail transit equipment, and in particular to an integrated converter device. Background technique [0002] In applications such as high-speed EMUs or urban rail transit, it is necessary to use traction, auxiliary or traction auxiliary integrated converter devices for traction, braking control and auxiliary load power supply for trains. [0003] Part of the existing traction converters and auxiliary converters are mostly loaded in independent cabinets, which takes up a lot of space for the very limited installation space under the high-speed EMU; and the existing traction converters and auxiliary converters Most of the devices adopt air cooling, and the cooling power of air cooling is limited by the load capacity of the power supply. After the load power of the power supply increases to a certain capacity, the use of air cooling heat dissipation technology is limited; at the same time, from the perspective of...

Problems solved by technology

[0003] Part of the existing traction converters and auxiliary converters are mostly loaded in independent cabinets, which takes up a lot of space for the very limited installation space under the high-speed EMU; and the existing traction converters and auxiliary converters Most of the devices adopt air cooling, and the cooling power of air cooling is limited by the load capacity of the power supply. After the load power of the power supply increases to a certain capacity, the use of air cooling heat dissipation technology is limited; at the same time, from the perspective of the overall layout, the cooling air duct is from the side of the equipment The air enters and then passes through the internal air duct of the converter, and the air is discharged from the other side. The internal space planning of the equipment is limited, the cooling and circuit layout are difficult, the installation, disassembly and maintenance of components are inconvenient, the cooling efficiency is not high, and it also brings a certain vibration to the equipment noise problem

[0004] Although some existing traction auxiliary integrated converter devices also use water cooling methods, because the water cooling design adopts a series method, the design is single, and if one component of the series water cooling device fails, it will cause the entire cooling system to cool down. Reduced efficiency or even cooling failure, which will affect the safety of the train group
