Transformer substation secondary device state monitoring system

A transformer substation secondary device state monitoring system achieves real-time sensing, monitoring early-warning, analysis and diagnosis and assessment prediction of a secondary device running state. A master station of the transformer substation secondary device state monitoring system consists of a database server, a GIS server, a WEB server, a longitudinal communication server, a time monitoring server and a network switch. A substation consists of a station-used end state monitoring device, a clock adapter and a clock performance comparison and acquisition device. The substation finishes acquisition and uploading of running states of a direct current system and a clock system of a transformer substation. The master station finishes the works of receiving statistic analysis warning control and the like of uploaded data of the substation. Based on the transformer substation secondary device state monitoring system, the secondary device security monitoring and control level is greatly improved, the service life of a device is prolonged, the running maintenance cost is reduced, and functions of an existing electric transmission and transformation device state monitoring system are perfected and supplemented.
