An integrated railway passenger car inverter module and inverter box

Abstract

The invention discloses an integrated passenger train inverting module and an inverter box. The inverting module comprises a cabinet body, a main circuit unit, a sensor detecting unit and a control unit; the main circuit unit, the sensor detecting unit and the control unit are integrally arranged in the cabinet body; and the control unit has multiple voltage output control modes; the sensor detecting unit detects signals of the main circuit unit; and the control unit controls the main circuit unit to convert a direct current into a three-phase alternating current based on the needed voltage output control mode and signals detected by the sensor detecting unit. The inverter box comprises a box body and more than one inverting module arranged in the box body. The integrated passenger train inverting module and the inverter box have the advantages such as compact structure, high degree of integration, easy installation, maintenance and debugging, and good compatibility.

Description

technical field [0001] The invention relates to the technical field of railway passenger cars, in particular to an integrated railway passenger car inverter module and inverter box. Background technique [0002] At present, among domestic railway passenger trains, in addition to EMUs and high-speed trains, there are still express (K) and direct express (Z) express passenger trains in operation. In order to provide passengers with a comfortable riding environment, express passenger trains are equipped with air conditioners, electric heating and other equipment. The trains are also equipped with dining cars. All the equipment and dining cars need to provide domestic electricity. As the core component of railway passenger trains, the passenger car inverter converts the DC600V DC input voltage into 3AC380 / 50Hz AC power to supply power to AC loads such as air conditioners, electric heating and dining cars of passenger cars. The inverter module is the core component of the passen...

AI Technical Summary

Problems solved by technology

[0004] (1) The components of the module are scattered and installed, which is not convenient for fault detection and maintenance. It takes a long time to find the fault point and replace the faulty unit when entering the station for maintenance;

[0005] (2) The module uses an independently set control box as the control system. The control box is large in size and needs to occupy a lot of space in the module, resulting in a very compact module space, which further makes installation and maintenance inconvenient;

[0006] (3) During the development and debugging of the converter, an external control system needs to be configured. Meanwhile, the inverter modules use different control algorithms on the ordinary car and the dining car and when performing debugging. Modules of different applications cannot be used in common, so It is necessary to develop the corresponding converter control software, so that more human resources are invested in the development of the converter, which prolongs the product development cycle and increases the product development cost;

[0007] (4) There is no signal detection sensor in the module, so that the module cannot be debugged separately, and corresponding debugging tooling is required
