Important electrical equipment such as high-voltage switchgear, cable connectors, and knife switch switches are prone to surface oxidation and corrosion, loose fastening bolts, equipment aging, wear, and overload operation during long-term operation, leading to a gradual increase in contact temperature, accelerated oxidation, continuous temperature rise, vicious cycle, and even accidents such as melting, combustion, and explosion, causing irreparable losses.

The system uses passive wireless temperature sensors to measure indoor temperature in real time/The temperature of the external electrical contact is uploaded to the monitoring platform through the receiving device. When the temperature rise of the contact exceeds the limit or the three-phase temperature is unbalanced, local and remote alarms are issued to prompt the operation and maintenance personnel to timely repair and maintain the electrical equipment, identify hidden dangers, and have important significance for the safe and reliable operation of the railway power supply system.

system diagram

Visually display the temperature and actual installation location of each node through a system diagram.

Temperature trend

View temperature trends at different nodes through real-time and historical curves, and promptly identify potential hazards.

Node visualization diagram

Visual diagram of temperature measurement nodes, which can clearly distinguish the current status of each node (normal) at a glance/Overtemperature/malfunction).

Three phase temperature data curve and difference

Analyze the temperature rise and abnormal conditions of each node through the three-phase temperature curve and difference, and issue timely alarms.

Alarm monitoring

Query and analyze historical alarm events during different time periods to provide reference for key equipment maintenance.

Environmental monitoring

In addition to monitoring the temperature of electrical equipment, it can also monitor the environmental conditions of the distribution room and provide services for the operation and maintenance of the distribution room.
