In the construction of smart grids, high-voltage switchgear is an important part of the power distribution system, and its safe operation is crucial. However, during long-term operation, the switch contacts, busbars, and outgoing line connections may increase contact resistance due to oxidation corrosion or loosening of fastening bolts, which may cause heating of the connection points and even burn the equipment, causing power outages.
In order to solve this problem, Hangzhou Liyi Electric Power Equipment Co., Ltd. launched a temperature online monitoring system solution, which aims to monitor the temperature changes of the high-voltage switchgear connection points in real time to prevent the occurrence of vicious cycles. The system communicates with the interval layer equipment through RS485 bus or Ethernet, and follows international standard Modbus-RTU, Modbus-TCP and other transmission protocols to ensure the safety, reliability and openness of the system.
System function highlights:
* Temperature display: The system can display the real-time temperature value of each temperature measurement point in the power distribution system, and supports remote data viewing on computer WEB and mobile phone APP.
* Temperature curve: View the temperature trend curve of each temperature measurement point to facilitate the analysis of equipment operation status.
*Running report: query and print the temperature data of each temperature measuring point at a specified time, which is convenient for equipment management.
*Real-time alarm: The system can issue an alarm for abnormal temperature at each temperature measuring point, support real-time voice alarm function, and various alarm methods, including pop-up window, voice alarm, etc., and can also push alarm messages through SMS/APP to remind the duty personnel in time.
*Historical event query: It can store and manage event records such as temperature exceeding the limit, which is convenient for users to trace the history of system events and alarms, query statistics, accident analysis, etc.
*Advanced high-performance industrial-grade microprocessor, strong data processing and information storage capabilities, high reliability, and fast running speed; 口Multiple sensors are available, and the appropriate temperature sensor can be selected according to the site requirements; 口Humanized menu design, simple, convenient and fast on-site debugging; 口Online temperature real-time measurement, high temperature accuracy and strong real-time performance; 口Adopt advanced storage technology, set parameters will not be lost after power failure; 口Wall-mounted installation, simple installation and easy disassembly
*With over-temperature alarm record query function, 200 historical over-temperature records can be queried
*With RS485 communication function to transmit data to the background in real time
*With 2G\4G Internet access function to realize network data connection and docking with cloud platform and APP
System hardware configuration:
The temperature online monitoring system is mainly composed of temperature sensors and temperature acquisition/display units at the equipment layer, edge computing gateways at the communication layer, and temperature measurement system hosts at the station control layer, to realize online temperature monitoring of key electrical parts of the power distribution system.
Through this system, users can realize real-time monitoring and early warning of the temperature of the connection points of high-voltage switchgear, thereby improving equipment safety and reducing equipment accident rate.
