The device for automatic voltage control on traction substations and contact networks

摘要

The invention relates to electrical engineering, in particular to the regulation of stress and may find application in devices for automatic control of the catenary voltage on electrified railways. A useful model solves the problem of creating a device for automatic regulation of voltage substation for the traction and the catenary having a high operational reliability owing to provide voltage boosting during operation in traction mode, locomotives and undervoltage in regenerative braking mode. To solve this problem in a device for automatically adjusting the voltage on the traction substations and the catenary, it is suggested according to the present utility model, enter the block of the signal exceeding the measured transformer-voltage measurement unit voltage substation above the stabilization voltage substation predeterminable setter level stabilization substation voltage, level setting device coupled with the stabilization voltage substation, a transformer with voltage measuring unit under Tanzi, and inputted to the first input element I. The second input of this AND gate is coupled to the output of forming the zero current value, and the output of AND inputted connected to the input of the signal switching unit of the inverter unit.
