Abstract

The invention provides a traction control unit and a control box. The traction control unit comprises a power module, an analog signal processing module, a digital signal processing module, a central processing module and an insulated gate bipolar transistor (IGBT) driving and feedback module. The traction control box comprises a box body; the traction control unit is arranged in the box body; one or more modules in the traction control unit are arranged on a sub-circuit board; the traction control unit consists of at least one sub-circuit board; the box body is provided with a mother board; the sub-circuit board is electrically connected and/or communicated with the mother board; a slot for accommodating the sub-circuit board is formed in the box body; and the sub-circuit board is inserted and fixed in the box body. Electric locomotives are subjected to alternating-current traction control, and the traction control unit and the control box provided by the invention has the characteristics of high traction power, high power factor, low harmonic interference, excellent traction and braking kinetic features, convenience for maintenance and the like.

Description

Technical field [0001] The invention relates to electric locomotive traction control technology, in particular to a traction control unit and a control box. Background technique [0002] With the rapid development of the national economy in recent years, the country has also increased its efforts in the construction of the railway industry year by year, and the railway industry has developed rapidly. At this stage, the leading domestic locomotive companies represented by CNR Group and CSR Group have the ability to design and produce various types of electric locomotives. However, the core part of AC electric locomotive control is still in a relatively backward stage and mainly depends on foreign production. Manufacturers, such as the CRH series of high-speed trains and the HXD series of trucks, are designed jointly with foreign manufacturers based on technology introduction. The core component of the control traction control unit is provided by foreign manufacturers. At present,...
