Embodiment approach 1

[0038] Such as image 3 , 4, Shown in 5 and 6: the transcoding method and transcoder of the decimal gear of the on-load tap changer of the transformer, the method passes the gear number of the decimal tap changer of the on-load transformer, that is, the gear voltage regulation signal through The transcoder is converted into a one-to-one corresponding voltage regulation signal. Its transcoder enables the gear conversion of the transformer on-load tap-changer to be displayed through the transmission display, measurement and control device or monitoring background.

[0039] The transcoder is used for direct on-site and remote display of gear positions. The transformer on-load voltage regulating mechanism box is electrically connected to the gear transmission display through the gear transcoder, and the gear transcoder is electrically connected to the measurement and control device and sent to the monitoring system in the monitoring background through the network. Transcoder, i...

Embodiment approach 2

[0050] Such as figure 1 , 4 , 5, the gear decimal transcoder of the transformer on-load tap-changer can also be used to directly display the decimal gear on the spot, and its working process is transformed by the gear of the transformer on-load tap changer box. The encoder is connected to the gear transmitter.

Embodiment approach 3

[0052] Such as figure 2 , 4 , 5, and 6, the gear decimal transcoder of the transformer on-load tap-changer can also be used for remote display of the decimal gear. The encoder is electrically connected to the measurement and control device and sent to the monitoring system in the monitoring background through a cable or network.

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 of the 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...
