Abstract

The invention discloses an automatic and efficient switching method of a kiln transmission standby frequency converter, which is applied to a standby frequency converter switching system and comprises the following steps that: an industrial personal computer carries out position arrangement on all transmission frequency converters based on the direction from a kiln head to a kiln tail, so that each transmission frequency converter has a respective position number; detecting the operation state of the transmission frequency converter; when one transmission frequency converter breaks down, the PLC module is controlled to close the moving end and the normally-open end of the alternating current contactor corresponding to the transmission frequency converter which breaks down, and the standby frequency converter is used for replacing the transmission frequency converter which breaks down according to the running state of current kiln transmission. According to the method, the faulted transmission frequency converter can be automatically and efficiently switched, so that the standby frequency converter replaces the faulted transmission frequency converter to work, and the switching method can still switch the faulted frequency converter in the operation state of acceleration, deceleration and segmented swinging of kiln transmission.

Description

technical field [0001] The invention relates to the technical field of kiln transmission automation control, in particular to an automatic and efficient switching method for a kiln transmission backup frequency converter. Background technique [0002] In the production process of building ceramic tiles, transmission is the key equipment for firing kilns. When using kiln transmission to process tiles, various transmission failures may occur, such as: frequency converter failure and Mechanical faults such as broken rods, broken chains, and stacked bricks require manual judgment and processing. However, long-term manual processing will cause large economic losses, and even easily expand the scope of faults during the processing. [0003] In the prior art, when the transmission of the kiln fails, the entire transmission of the kiln is generally shut down, and then troubleshooting is performed. This approach will undoubtedly have an impact on production. Therefore, there is an ...
