The DSP mainboards are to control the DSP mainboards that label is DSP.
GPRS communication modules are additionally provided with the DSP mainboards, to be communicated with host computer.
The DSP mainboards be voltage on the transformer transformer collection plate to be collected, Electric current carries out judgement process, it is determined whether faulty generation and do the DSP mainboards of respective handling.
The liquid crystal board is provided with LCD liquid crystal display screen.
The liquid crystal board is provided with redness and green LED indicator lamp, to show transformer fault Generation and disappearance.
The embodiment of the present invention is primarily adapted for use in 10KV and following high-tension switch gear and distribution network systems. For detecting, indicating, transmitting transformer device fault-signal.When transformer breaks down, energy Fault message is transmitted in time to host computer, to be processed.
The foregoing is only presently preferred embodiments of the present invention, not to limit the present invention, it is all Within the spirit and principles in the present invention, any modification, equivalent substitution and improvements made etc., Should be included within protection scope of the present invention.
