HF-W-702 Switchgear Temperature Monitoring

Wireless Temperature Monitoring System for Power Distribution Cabinets

The switchgear temperature monitoring system monitors the temperature of core components inside distribution cabinets in real time to ensure the safe operation of equipment. By collecting, transmitting and analyzing temperature data via wireless technology, the system can promptly identify abnormal temperature rise and prevent equipment faults and safety incidents resulting from overheating.

System Composition

Wireless Temperature Sensors

Installed on core heat-generating positions inside distribution cabinets, including switch contacts, busbars and cable connectors. They monitor real-time temperature of these points and send temperature signals to the wireless temperature monitor via wireless network. Features include high measurement precision, low power consumption and strong anti-interference capability.

Main Unit for Wireless Temperature Monitoring

Receives temperature data uploaded by wireless sensors and executes preliminary data processing. It forwards data to the early warning workstation via wired or wireless communication.

Temperature Monitoring & Early Warning Workstation / Platform

Serves as the core of the whole system, undertaking centralized data display, analysis, storage and abnormal warning. Users can check real-time temperature readings via computers or mobile APPs, and receive alarm notifications once temperature goes out of limit.

Installation Steps

Step 1

Pass an alloy power pick-up strip of appropriate length through the module.

Step 2

Insert the alloy power pick-up strip and soft silicone pad into the sensor. The corrugated side of the silicone pad shall face downward and align with the temperature induction position.

Step 3

Wrap the module around the power-taking section (main current path) to make the temperature measuring point closely contact the target measured position. Tighten the alloy strips on both sides, then tuck and overlap the two ends of the pick-up strip under the buckle.

Step 4

Tighten the screws with an Allen hex wrench, and push the soft silicone pad to both sides of the connector.

System Functions

1. Real-time Monitoring Continuous real-time temperature tracking inside cabinets to capture temperature anomalies without delay.
2. Wireless Data Transmission Eliminates the drawbacks of traditional wired temperature measurement, greatly improving system flexibility and stability.
3. Data Processing & Analysis The workstation centrally displays, analyzes and archives all collected data and triggers automatic early warnings.
4. Alarm Notification The system automatically sends out alerts when temperature exceeds preset thresholds to prompt maintenance staff for troubleshooting.
5. Remote Supervision Remote access to temperature data through PC terminals or mobile APPs enables long-distance monitoring and management of distribution cabinets.
