Acrel-2000T wireless temperature measurement and monitoring system technology

Overview

Acrel-2000T wireless temperature measurement and monitoring system device is suitable for temperature monitoring of cable joints, circuit breaker contacts, knife switches, high-voltage cable intermediate ends, dry-type transformers, low-voltage and high-current equipment in high- and low-voltage switch cabinets to prevent errors during operation. Due to oxidation, looseness, dust and other factors, the contact resistance of the contacts is too large and heating becomes a safety hazard. Improve equipment safety, reflect the equipment operating status in a timely, continuous and accurate manner, and reduce the equipment accident rate.

Ankerui wireless temperature measurement and monitoring system communicates directly with the equipment at the bay level through the RS485 bus or Ethernet. The system design follows the international standard Modbus-RTU, Modbus-TCP and other transmission protocols, and security, reliability and openness are all achieved. improve. The system has remote signaling, telemetry, remote control, remote adjustment, remote setting, event alarm, curve, bar graph, report and user management functions. It can monitor the equipment operation status of the wireless temperature measurement system, achieve rapid alarm response, and prevent serious failures. .

2 Application places

It is suitable for temperature monitoring of power equipment in the ubiquitous power Internet of Things, substations, steel plants, chemicals, cement, data centers, hospitals, airports, power plants, coal mines and other factories and mines, as well as power transformation and distribution stations.

4 system functions

The temperature measurement system host Acrel-2000T is installed in the duty monitoring room and can remotely monitor the operating temperature status of all switching equipment in the system. The system has the following main functions:

1) Temperature display: Displays the real-time value of each temperature measurement point in the power distribution system, and can also remotely view data via computer WEB/mobile phone APP.

2) Temperature curve: View the temperature trend curve of each temperature measurement point.

3) Run report: Query and print the temperature data of each temperature measurement point at the specified time.

4) Real-time alarm: The system can issue alarms for abnormal temperatures at each temperature measurement point. The system has a real-time voice alarm function, which can issue voice alarms for all events. The alarm methods include pop-up windows, voice alarms, etc. It can also push alarm messages via SMS/APP to promptly remind the personnel on duty.

5) Historical event query: It can store and manage event records such as temperature limit violations, which facilitates users to trace the history of system events and alarms, query statistics, and analyze accidents, etc.

5 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 transformation and distribution system.
