The invention discloses a transformer station equipment temperature monitoring system based on multi-angle electronic tag identification. The transformer station equipment temperature monitoring system comprises a plurality electronic tags marked with equipment ID information and installed on transformer station equipment; a temperature acquisition device including a movable vehicle equipped with a vehicle driving device, an infrared temperature-measuring sensor, and a tag reader-writer; and a monitoring device including a server in communication with the electronic tags, the vehicle driving device, the infrared temperature-measuring sensor, and the tag reader-writer, and a first display screen connected to the server. The infrared temperature-measuring sensor and the tag reader-writer are rotationally connected with the vehicle via an angle adjusting device. The angle adjusting device is electrically connected with the server. The temperature-measuring sensor and the tag reader-writer are rotationally connected with the vehicle via the angle adjusting device so that monitoring precision is increased.
