For many years, due to the limitations of the technical level, although infrared thermometer, infrared imager, temperature sensing cable, traditional point-type temperature measurement system have been used to solve the above problems, but can not achieve the switch cabinet such as circuit breaker, the connection point and contact temperature measurement.
Project Overview
DigIoT is an electric IoT company, providing electrical IoT services for local substations. Customer consults Acrel wireless temperature measurement products, attending through Acrel ATE wireless temperature sensor and ATC receiver, the cable in the switchgear temperature detection, And through RS485 communication data transmission to the back platform for real-time monitoring, can effectively prevent overheating failure, affect the normal operation of equipment, avoid safety risks.
Wireless Temperature Measurement Solution
Acrel on-line temperature measurement device is suitable for the temperature detection of high and low voltage switches, circuit breaker contacts, high voltage cable middle heads, low voltage and high current equipment, to prevent contact caused by oxidation, loosening and other factors during operation Excessive contact resistance and heat generation become a safety hazard, timely, continuous and accurate reflection of equipment operating status, and equipment safety.
