Control device for auxiliary current transformer and auxiliary current transformer system

Abstract

The invention discloses a control device for an auxiliary current transformer, which is used for controlling an auxiliary current transformer module. The control device comprises a first power supply plug-in component, a digital input / output plug-in component, an analog input / output plug-in component, a first control plug-in component, a multifunctional vehicle bus MVB (Multifunction Vehicle Bus) plug-in component, a second control plug-in component and a second power supply plug-in component which are sequentially arranged in a case. Through the above plug-in components, the control device achieves system management, logical judgment and control and fault protection of the auxiliary current transformer module, and meanwhile, can serve an analog signal processing function and a digital signal processing function and provide working power supplies for a sensor and the like of the auxiliary current transformer module. The control device provided by the embodiment of the invention has perfect functions and unified interfaces, and can improve the development efficiency of the auxiliary current transformer, lower the research and development costs and facilitate unified product maintenance.

Description

technical field [0001] The invention relates to the technical field of converters, in particular to a control device for an auxiliary converter and an auxiliary converter system. Background technique [0002] With the rapid development of my country's urban rail transit, more and more auxiliary converter products are applied to urban rail transit vehicles, such as subway vehicles. The auxiliary converter control device is the core component of the auxiliary converter product. [0003] Some of the auxiliary converter control devices currently used are built from circuit boards with multiple functional blocks, and their structures and interfaces are not uniform; some use plug-in box structures, but their functions are not perfect or their interfaces are not unified. [0004] With the development of technology, auxiliary converter products present a diversified development trend. However, the existing control devices are difficult to meet the diversification requirements of t...

AI Technical Summary

Problems solved by technology

However, the existing control devices are difficult to meet the diversification requirements of the auxiliary converter, which leads to the problem of redesigning the hardware every time a new product of the auxiliary converter is developed, thus reducing the auxiliary converter's cost. Development efficiency increases research and development costs, which is not conducive to unified maintenance of products
