Intelligent pressing plate monitoring system of transformer substation

The utility model discloses an intelligent pressing plate monitoring system of a transformer substation. The intelligent pressing plate monitoring system comprises infrared emitting tubes, infrared receiving tubes, switching signal receiving devices, a network switch and a background monitoring machine, wherein the infrared emitting tubes and the infrared receiving tubes are installed in a protective screen of a monitored transformer substation in pairs; because of the installation positions of the infrared emitting tubes and the infrared receiving tubes, the infrared receiving tubes can only receive infrared rays emitted by the infrared emitting tubes through reflection by metal connecting sheet of secondary pressing plates when the secondary pressing plates installed in the protective screen are at switching-on positions; a signal output end of each infrared receiving tube is connected with a signal input end of the corresponding switching signal receiving device; a signal output interface of each switching signal receiving device is connected with a signal input interface of the network switch; and the network switch is connected with the background monitoring machine through the Ethernet. The intelligent pressing plate monitoring system realizes the monitoring on switching-on/off positions of the secondary pressing plates in the transformer substation, and cannot affect the status of the secondary pressing plates and a current loop.
