The invention provides a static debugging system for a suspension rail vehicle. The system comprises an input stage circuit; an alternate-current source passes through the input stage circuit, a rectifying and filtering circuit, a series resonant full-bridge inversion circuit, a high-frequency voltage transformation circuit, and a high-voltage rectifying circuit, so that direct current can be outputted; the direct current is divided into two paths, wherein one path is outputted to the outside, and the other path is connected with a feedback network circuit through an output sampling circuit; the feedback network circuit feeds back information to a PWM controller and a system logic controller separately; the system logic controller processes received data and transmits the processed data tothe input stage circuit and the PWM controller separately; the PWM controller transmits the processed data to the series resonant full-bridge inversion circuit; and therefore, a closed loop can be formed. The static debugging system of the suspension rail vehicle of the present invention has the advantages of simple structure and low cost of power supply equipment, can improve static debugging power supply quality, avoid mutual interference between static adjustment and dynamic adjustment, improve production and maintenance efficiency, and has good economic benefits.
Description
technical field [0001] The invention belongs to the field of static debugging systems for urban rail transit, in particular to a static debugging system for suspended rail vehicles. Background technique [0002] The static commissioning of rail vehicles is an important process after the final assembly of urban rail vehicles is completed and before dynamic commissioning. It is necessary to check the traction system, high and low voltage equipment, control circuits and other parts according to the work steps. The characteristics of low load and high power supply quality requirements. Most of the existing urban rail static power supply systems are powered by DC traction substations or DC traction networks, and the quality of power supply is easily affected by external power grids and transmission distances. Contents of the invention [0003] In view of this, the present invention aims to propose a static debugging system for suspended rail vehicles to provide a system with s...
