With the continuous expansion of the scale of power systems and the advancement of technology, it is becoming increasingly important to monitor the operating status of key power equipment such as transformers, switchgear, and circuit breakers. Among them, temperature is one of the key indicators reflecting the health of equipment. Its accurate monitoring helps to detect potential faults in time and prevent accidents. In recent years, wireless temperature measurement induction power CT coil has been widely used in the power industry as a new type of passive temperature monitoring method.1. Energy collection based on electromagnetic inductionThe core of wireless temperature measurement induction power CT coil is that it can use the principle of electromagnetic induction to collect energy from the surrounding environment to power the temperature sensor. When current flows through the conductor of a transformer or circuit breaker, an alternating magnetic field is generated around it. The wireless temperature measurement induction power CT coil converts this part of the magnetic field energy into electrical energy by wrapping around the outside of the conductor, thereby driving the built-in temperature sensor to work.The biggest advantage of this passive power supply method is that it does not require external power support, which reduces the difficulty of wiring and reduces maintenance costs. Especially in some places where it is difficult to access the power supply, such as the cable joint on the high-voltage side, the advantages of wireless temperature measurement induction power CT coil are particularly obvious.2. Efficient data acquisition and transmissionIn addition to energy collection, wireless temperature measurement induction power CT coil also needs to complete efficient data acquisition and transmission tasks. Modern wireless temperature measurement induction power CT coil usually integrates highly sensitive temperature sensors and low-power wireless communication modules. The temperature sensor is responsible for real-time sensing of temperature changes on the surface or inside of the device and sending the collected data to the wireless communication module.In order to ensure the reliability and stability of data transmission, wireless temperature measurement induction power CT coil adopts a variety of advanced wireless communication protocols, such as Zigbee, LoRa, etc. These protocols have strong penetration and low power consumption, and can maintain stable connections in complex industrial environments. At the same time, with the support of smart gateways or cloud platforms, users can view the temperature information of the device anytime and anywhere through mobile phone APP or computer software to achieve remote monitoring.3. Strong anti-interference abilityDuring the operation of power equipment, there are often strong electromagnetic interference sources around, which poses severe challenges to the data acquisition and transmission of wireless temperature measurement induction power CT coil. To this end, manufacturers have taken a series of measures to enhance the anti-interference ability of products.First, in terms of hardware design, shielding covers, filter circuits and other means are used to protect sensitive components; secondly, at the software level, adaptive filtering algorithms and error correction coding technologies are introduced to effectively filter out noise interference and ensure the integrity and accuracy of data. In addition, some high-end products are also equipped with an automatic retransmission mechanism, which will immediately resend data once data loss or errors are detected, further improving the reliability of the system.4. Broad application prospectsWith its unique technical advantages, wireless temperature measurement induction power CT coil has shown broad application prospects in temperature monitoring of various power equipment such as transformers, switch cabinets, circuit breakers, and cables. It can monitor the temperature of key parts of the equipment in real time, help operation and maintenance personnel to warn of possible overheating hazards in advance, and avoid major accidents caused by local overheating. Especially in the context of smart grid construction, wireless temperature measurement induction power CT coil will become an indispensable part of realizing intelligent equipment management.In short, wireless temperature measurement induction power CT coil has achieved efficient passive temperature monitoring of power equipment by cleverly combining multiple advanced technologies such as electromagnetic induction, wireless communication and intelligent algorithms. This not only improves the safety and reliability of the power system, but also provides strong support for the intelligent operation and maintenance of future power equipment.
