Description

Technical Field

[0001] The present invention relates to the technical field of alarm devices, in particular to a distribution transformer power failure alarm device. Background Art

[0002] Distribution transformer, referred to as "distribution transformer", refers to a static electrical device that transforms AC voltage and current to transmit AC power in the power distribution system according to the law of electromagnetic induction. Distribution transformers usually operate in the distribution network with a voltage level of 10-35kV and a capacity of 6300kVA and below, directly supplying power to end users. Its function is to convert the electric energy of high-voltage transmission lines into low-voltage electric energy suitable for household, industrial and commercial use; However, during the operation of the distribution transformer, power outages often occur due to various reasons, thus affecting the operation of the transformer. When there are multiple transformers in one place at the same time, if an unexpected power outage occurs, it will be impossible to determine in time which transformer has failed. At this time, manual inspection of the transformer is required, and then maintenance is carried out after the inspection. This work process is relatively time-consuming and labor-intensive, resulting in low work efficiency and inconvenience for people to use. For this reason, we propose a distribution transformer power outage alarm device. Summary of the invention
