The invention provides a transformer voltage abnormality alarm in order to know transformer voltage abnormality in time to remove abnormality and improve power supply quality as early as possible. The transformer voltage abnormality alarm comprises a voltage measurement module, a voltage abnormality judgment module, an SMS (Short Messaging Service) short message communication module, a display setting module and a self-contained power supply module, wherein the voltage measurement module is used for measuring voltage in real time and provides a digital signal measurement result to the voltage abnormality judgment module; the voltage abnormality judgment module is used for analyzing and judging whether voltage is abnormal or not; the SMS short message communication module is used for sending an alarm short message to remote communication equipment. The transformer voltage abnormality alarm provided by the invention has the advantages that the alarm can be given immediately when the voltage of the transformer is abnormal, the fault can be solved in the shortest time, the influence of voltage abnormality on users is reduced and the high-quality service level of power supply is greatly improved.
Description
technical field [0001] The invention belongs to the field of transformer fault detection devices, and more specifically relates to a transformer voltage abnormality alarm, which is used for real-time monitoring of transformers and metering point voltages by power supply departments. Background technique [0002] In recent years, the power supply network has become increasingly complex, and voltage abnormalities (including low voltage, high voltage, and power outages, etc.) caused by transformer failures often occur during the power supply process. A fault in a power transformer can lead to wide-ranging consequences in the form of electrical failure to a wide range of customers and in the form of having to replace or at least repair the faulty transformer. If the voltage is in an abnormal state for a long time, it will cause losses to users, and in severe cases, it will cause equipment damage and product scrapping, resulting in power disputes and damaging the image of power s...
