The Internet of Things (iot) technology is comprehensively empowering industrial upgrading. As a core national infrastructure, the safe and stable operation of equipment in the power industry is directly related to people's livelihood and industrial production. Power equipment is constantly exposed to harsh conditions such as high voltage and high load. Local overheating can easily lead to malfunctions, power outages and even fire hazards. The shortcomings of traditional temperature measurement methods are no longer suitable for modern operation and maintenance requirements.
As a national high-tech enterprise deeply engaged in the RFID field, Quanshunhong Technology focuses on the pain points of temperature measurement in the power industry. With its mature RFID temperature measurement technology and one-stop solutions, it provides an innovative path for temperature monitoring of power equipment and helps power operation and maintenance move towards intelligence and unmanned operation. Combining the special demands of the power industry, this paper analyzes the core technological advantages and scenario-based applications to empower the safe operation and maintenance of the power industry.
Differences between Temperature Measurement of Power Equipment Based on RFID and Traditional Temperature Measurement:
The operating environment of power equipment is special, featuring high voltage and electricity, confined space, strong electromagnetic interference, and scattered distribution. This places extremely high demands on the temperature measurement system. The drawbacks of traditional infrared inspection, manual spot checks, and wired temperature measurement modes are obvious: manual inspection is inefficient, has blind spots in monitoring, and cannot be monitored in real time for 24 hours. Wired temperature measurement wiring is complex, which damages the insulation of equipment, poses high safety risks in high-voltage scenarios, and incurs high operation and maintenance costs. Ordinary temperature measurement devices have poor anti-interference and high-temperature resistance capabilities, making it difficult to accurately capture early temperature anomalies.
Temperature is a core indicator of the health of power equipment. At key nodes such as switch cabinets, cable joints, and busbars in substations, if the temperature exceeds the standard without timely warning, it is very likely to cause a chain of safety accidents. Therefore, developing passive wireless, real-time accurate and highly adaptable temperature measurement solutions has become a core and essential need for intelligent power operation and maintenance.
Core advantages of real-time temperature measurement management for RFID power equipment:
Quanshunhong Technology focuses on the research and development, sales and solutions of wireless radio frequency technology products in the Internet of Things industry. It creates ultra-high frequency RFID temperature measurement solutions, breaks through traditional technical bottlenecks, perfectly ADAPTS to the harsh working conditions of power, and has seven core advantages, fully meeting the temperature measurement needs of equipment.
Passive wireless design: The tag does not require an external power supply or wiring. It operates based on the energy of the radio frequency field, avoiding wiring risks, not affecting the insulation of the equipment, and has zero threshold for installation and modification.
Anti-metal precise temperature measurement: Exclusive anti-metal process, can be directly attached to the surface of metal equipment, with high temperature measurement accuracy, accurately capturing subtle temperature changes and eliminating missed or misjudged detections.
Real-time full-area monitoring: Supports 7× 24-hour continuous temperature measurement, synchronously collects data from multiple measurement points, and builds a full-area temperature monitoring network.
Low cost and easy operation and maintenance: The label is compact, easy to install, and does not require battery replacement, significantly reducing manual operation and maintenance costs.
Industrial-grade high durability: Stable and reliable quality, long service life, suitable for long-term continuous operation of equipment, and uninterrupted data transmission.
Remote intelligent early warning: Supports remote monitoring, multi-level threshold alarm, real-time push of abnormal temperatures, and enables advanced prediction of faults.
Full-scenario customizable: Compatible with various power equipment models, covering the temperature measurement requirements of all categories such as switch cabinets, cables, substations, and ring main units.
Core scene application management of real-time power temperature measurement based on RFID
• Full-process temperature measurement of power cables to eliminate the risk of overheating and fire:
Cables are the core carriers for power transmission. Joints, cable trays and other parts are high-risk areas for faults. Long-term high loads can easily cause overheating due to excessive contact resistance. Quanshunhong RFID temperature measurement tags can be fixed at key nodes of cables to achieve real-time temperature measurement throughout the process, accurately capture abnormal fluctuations, issue early warnings of overheating risks, prevent fire and insulation breakdown accidents, and at the same time retain data to provide a basis for fault diagnosis and maintenance, ensuring the smoothness of the power transmission link.
• Intelligent temperature measurement of substation equipment to ensure the stability of power grid hubs:
As the core hub of the power grid, substations have a large number of devices, are widely distributed, and have high operation and maintenance requirements. Traditional inspection methods are difficult to monitor comprehensively and accurately. The Quanshunhong RFID temperature sensor can be flexibly installed on core equipment such as transformers, busbars, and switch cabinets, achieving unmanned remote real-time temperature measurement and avoiding the risks of high-voltage operations. The system can synchronously monitor a large number of temperature measurement points, upload data to the platform in real time, and immediately alarm for any abnormality, helping operation and maintenance personnel quickly locate faults, achieve preventive operation and maintenance, and improve the stability of substation operation.
• Precise temperature measurement for high-voltage switch cabinets/ring main units, eliminating monitoring blind spots
The internal space of high-voltage cabinets and ring main units is sealed and the live nodes are densely distributed. Traditional temperature measurement methods are difficult to cover the key heat sources inside, which is prone to form monitoring blind spots. The Quanshunhong RFID temperature measurement tag is compact in size and can be attached to the core position inside the cabinet. Its passive and wireless features are not affected by space or interference, enabling real-time temperature measurement at all nodes. This effectively eliminates equipment burning and sudden power outages from the source, ensuring the safe operation of power distribution equipment.
With the acceleration of smart grid construction, the demand for digital and intelligent operation and maintenance in the power industry has been continuously rising. Passive RFID temperature measurement technology, with its core advantages, has become the mainstream solution for temperature measurement of power equipment and has broad application prospects in the future.
