Problems solved by technology

However, when the main transformer is replaced or the monitoring system of the substation is transformed, there will be interface inconsistencies due to various reasons, resulting in the inability to transmit the stall information correctly; when the substation is built in stages, the system operation mode of the monitoring system has been fixed in Phase I , when the phase II main transformer is installed, if it is inconsistent with the type of the main transformer tap changer of the I phase, it will cause abnormal information transmission, resulting in abnormal operation of the substation monitoring system and VQC device; when the main transformer on-load tap changer or monitoring system After the data acquisition device is replaced, the polarity of the gear information or the interface will be inconsistent, resulting in the gear information not being sent normally

Abstract

The invention discloses an on-load tap-changer intelligent gear conversion device. The on-load tap-changer intelligent gear conversion device comprises an entering module. The entering module is in signal connection with a central processing unit (CPU) module, the CPU module is in signal connection with a departing module, and the departing module is in signal connection with a power module. According to the on-load tap-changer intelligent gear conversion device, due to ponderomotive force of the entering module and the departing module to gear information, and internally-arranged programmable logic controller (PLC) industrial control chips of the CPU, conversion of the gear information can be achieved through the method of fixed program and manual programming, and therefore various interfaces can be compatible, and the intelligent conversion of the gear information can be achieved.

Description

[0001] technical field [0002] The invention relates to an intelligent gear conversion device for an on-load tap changer. [0003] Background technique [0004] The newly designed substation, monitoring system or VQC device generally considers the interface problem with the gear transmission mode of the on-load tap-changer during the design, which has satisfied the correct transmission of the gear information of both parties. However, when the main transformer is replaced or the monitoring system of the substation is transformed, there will be interface inconsistencies due to various reasons, resulting in the inability to transmit the stall information correctly; when the substation is built in stages, the system operation mode of the monitoring system has been fixed in Phase I , when the phase II main transformer is installed, if it is inconsistent with the type of the main transformer tap changer of the I phase, it will cause abnormal information transmission, resulting ...
