Transcoding method for denary shift of transformer on-load tap-changer and transcoder

Abstract

The invention discloses a transcoding method for a denary shift of a transformer on-load tap-changer and a transcoder. The transcoding method aims to convert denary output shift pressure regulating signals of a transformer on-load tap-changer to one-to-one correspondence pressure regulating signals through a shift transcoder and comprises on-site display, remote display, on-site and remote display directly used for the denary shift. Converting the denary output shift pressure regulating signals to the one-to-one correspondence pressure regulating signals comprises the following steps: I. the transcoder outputs one-to-one correspondence shift pressure regulating signals W1-W7; II. the transcoder outputs one-to-one correspondence shift pressure regulating signals W8-W10; and III. the transcoder outputs one-to-one correspondence shift pressure regulating signals W11-W17. The invention is suitable for a 110KV denary shift on-load transformer and can convert the denary shift information ofthe transformer to one-to-one correspondence shift information which can be identified by a main transformer measurement and control system. The invention has the advantages of simple design, low cost, convenient installation and great reliability.

Description

technical field [0001] The invention relates to the technical field of switch gear conversion display, in particular to a transcoding method and a transcoder for the decimal gear of a transformer on-load tap changer, which are suitable for the display of the decimal gear of a transformer on-load tap changer. Background technique [0002] At present, with the development of the electric power industry, there are more and more on-load tap changer transformers, which play a positive role in connecting the power grid, regulating the reactive power flow, and stabilizing the voltage of the load center, and are welcomed by users. With the increase of on-load tap changing transformers, on-load tap-changers have also been widely used. The on-load tap-changer is used to change the secondary output voltage by changing the number of transformer turns when the secondary load is uninterrupted. According to different voltage levels, the corresponding taps are drawn out from the transforme...
