The present invention discloses a method and device for transformer station personnel behavior identification. The method comprises the following steps: obtaining video images of monitoring areas of atransformer station; extracting personnel state data collected in the video images, and determining whether there is a personnel behavior breaking a rule or not in the monitoring areas according to apreset rule; and when detecting that there is a personnel behavior breaking the rule in the monitoring areas, emitting an alarm. The device provided by the invention uploads collected video images inan upper computer connected with the device, and the upper computer is configured to analyze the video images and determines cases of each monitoring area. The device provided by the invention can emit alarm and perform prompting when the personnel behavior does not satisfy requirements. Therefore elaborate degree and timeliness of transformer station area monitoring can be greatly improved, a camera device is combined to a computer to perform personnel behavior monitoring to realize automatic monitoring of the personnel in a transformer station so as to timely discover behaviors being against rules while reducing labor force, reduce an accident rate and ensure safety of a transformer station area.
