Title:
DISTRIBUTION TRANSFORMER THAT STORES STATE INFORMATION, DISPLAY DEVICE AND CONTROL METHOD OF THE DISTRIBUTION TRANSFORMER
Document Type and Number:
WIPO Patent Application WO/2010/134754
Kind Code:
A2
Abstract:
The present invention relates to a distribution transformer that stores state information, a display device and a control method of the distribution transformer. The present invention comprises: an external memory for storing period and time information for sensing a state of a transformer; a state sensing block for sensing an internal state of the transformer; and a control module which stores the transformer's state information sent from the state sensing block in the memory, when the period and time stored in the memory come. The present invention stores overall conditions of the transformer, namely, load, current, temperature, acid value of insulating oil, in a memory at the desired period and time by the user, and this recorded information can be used later as a history state in the event of a transformer failure or when needed. In so doing, a transformer failure can be avoided in advance, and when a failure occurs a secondary failure can be prevented by checking the state of the transformer at a corresponding problem spot.
