Induction pickup temperature online monitoring system

System Components

IN-302 wireless temperature measurement system is mainly used to measure the temperature of high-voltage electrical contacts, such as the exposed contacts in the high-voltage switchgear, busbar connections, cable heads, circuit breaker contacts and transformer inlet and outlet piles. Sensor by the wireless transmission circuit, CPU logic control circuit, signal modulation and amplification circuit, temperature sensor and other components. The wireless temperature measurement and reception host can be installed locally by instrumented host, or centralized reception by touch host.

The switchgear wireless temperature measurement system has outstanding safety guarantee, which can real-time monitor the temperature of key parts such as busbar electrical nodes, circuit breaker contacts, cable joints, etc., and provide timely warning in case of abnormality, and it adopts non-contact measurement to avoid the safety risk of contact temperature measurement under high voltage and strong electric field without affecting the normal operation of equipments. Operation and maintenance efficiency is greatly improved. No need for manual on-site temperature measurement one by one, the system automatically collects data and remote transmission, reducing the workload of operation and maintenance; but also long-term record storage of temperature data, generating reports and trend charts, help analyze the pattern of change of equipment temperature, to provide a scientific basis for the maintenance of equipment, and to realize the change from "after the fact maintenance" to "before the fact prevention". Preventive" change from "maintenance after the fact" to "prevention before the fact".
