The invention relates to an anti-theft intelligent warner of a distribution transformer. The warner comprises a light control circuit, an infrared frequent detection circuit and a remote warning circuit; one end of the light control circuit is connected with the infrared detection circuit, the infrared detection circuit is connected with the remote warning circuit, and an output signal of the remote warning circuit is transmitted onto an intelligent control center of a distribution network or a mobile telephone of an electrician; when the condition of theft occurs in a transformer, the signal is immediately transferred to a warning transmission circuit for carrying out remote warning, and an attendant obtaining the warning condition goes to a site for carrying out treatment immediately at the first time; according to the remote warner, an advanced electronic technology is utilized, and a remote warner for the intelligent management of the safety of the transformer is developed; and by applying the anti-theft intelligent warner of the distribution transformer, the occurrence of the theft accident of the transformer is reduced, the power supply reliability is enhanced, and the benefits of an enterprise and the society are increased.
