Abstract
The utility model discloses an intelligent alarm device of a transformer, which comprises a temperature detection unit, a current sampling circuit, a control unit, a network server and an alarm unit, wherein the temperature detection unit and the current sampling circuit are used for measuring temperature and current of the transformer respectively; output terminals of the temperature detection unit and the current sampling circuit are connected with an input terminal of the control unit; the control unit is communicated with a server through a communication module; and an output terminal of the server is connected with the alarm unit. The intelligent alarm device of the transformer, provided by the utility model, can detect the contact temperature, three-phase voltage of and three-phase current of the transformer in a real-time manner; and when temperature or (voltage and current) exceeds a set value, alarm signals are sent to working personnel, so that working personnel can repair the transformer in a real-time manner. Therefore, the intelligent device ensures safe operation of the transformer as well as ensures that lives and works of surrounding residents are not influenced by power failure.
Description
Technical field
The utility model relates to the power transformer field, relates in particular to a kind of intelligent transformer warning device.
Background technology
At present, power transformer often breaks down when peak of power consumption, when too high or current loading is excessive when contact temperature even burn, also may blow out phenomenon; Sometimes also because the phenomenon of voltage fluctuation shakiness appears in superpotential, cause certain influence to the user.And if after transformer broke down, it was longer to repair the time that needs usually; Then need the longer time to remove to change transformer if burn, maintenance or replacing all need be carried out under the situation that has a power failure, and this has just influenced the live and work of surrounding resident greatly.
The utility model content
The purpose of this utility model provides a kind of intelligent transformer warning device, guarantees that transformer normally moves.
The utility model adopts following technical proposals: a kind of intelligent transformer warning device, comprise temperature detecting unit, current sampling circuit, control module, the webserver and alarm unit, temperature detecting unit and current sampling circuit are used for the temperature and the electric current of measuring transformer respectively, the output terminal of temperature detecting unit and current sampling circuit is connected with the input end of control module, control module communicates by communication module and server, and the output terminal of server is connected with alarm unit.
Also include the voltage sampling circuit that detects the transformer phase voltage, the output terminal of voltage sampling circuit is connected with the input end of control module.
Described control module comprises A/D change-over circuit and controller, and the output terminal of A/D change-over circuit is connected with the input end of controller.
Described communication module is the GPRS wireless communication module.
The utility model intelligent transformer warning device detects contact temperature, three-phase voltage and the three-phase current of transformer in real time, when temperature or voltage, when electric current surpasses setting value, just send alerting signal and give the staff, the staff is in time keeped in repair transformer, guaranteed the safe operation of transformer, the while has also guaranteed the influence that the live and work of surrounding resident is not had a power failure.
Description of drawings
