Against the backdrop of rapid development in the power industry, power station equipment has put forward strict requirements for temperature monitoring accuracy, stability, and environmental adaptability. Shanghai Automation Instrument Co., Ltd. (hereinafter referred to as“Shanghai Automation”）The power station specific thermocouple launched has become a leader in temperature measurement for domestic power stations due to its technological advantages and reliable performanceThe benchmark of the domainThe product is widely used in key scenarios such as high-temperature and high-pressure steam pipelines, boilers, and steam turbines.

1、 Wide temperature range and high precision: covering the full scenario requirements of power plants

The thermocouples of Shanghai Automation Power Station adopt nickel chromium-Nickel silicon（KType), nickel chromium-Copper nickel（EStandardized division marks such as type, temperature measurement range coverage-40℃to1370℃It can accurately match the temperature measurement needs of different equipment in the power station. For example, itsWRNR-13The thermocouple is designed specifically for high temperature and high pressure environments, with a temperature measurement range of up to0-800℃The nominal pressure can reach29.4MPaThe flow rate tolerance reaches100m/sCan stably monitor steam pipelines and boilersExtreme withinWorking conditions. In terms of precision control, this series of products complies withJB/T9238-1999andJB/T8622-1997Standard,ⅠThe allowable deviation for precision products is only±1.5℃or±0.004 │t│（tTo ensure the high reliability of temperature data and provide accurate decision-making basis for the operation of the power station, based on actual temperature measurements.

2、 Structural Innovation: Enhancing Equipment Lifespan and Maintenance Efficiency

In response to the long-term operation and frequent maintenance of power station equipment, Shanghai Automation has developed a hot sleeve thermocouple structure. This design separates the protective sleeve from the thermocouple, and users can first weld or mechanically fix the thermal sleeve onto the equipment before installing the thermocouple element. This innovative structure significantly improves the pressure bearing capacity and service life of the protective tube, while facilitating component replacement and reducing downtime maintenance costs. For example, itsWRNR2-13The double branch thermocouple adopts0Cr18Ni12Mo2TiStainless steel protective tube, combined with deep blind hole processing technology, does not require welding at the end, improving strength30%Above, it can withstand long-term erosion of high temperature and high pressure steam, reducing the risk of unplanned shutdown.

3、 Environmental adaptability: fearless of harsh working conditions and challenges

The power station environment is complex, with multiple challenges such as high temperature, high pressure, vibration, and corrosion. Shanghai Automation Power Station Thermocouples have achieved full scene adaptability through material optimization and process upgrades

Corrosion resistance: The protective tube adopts316LStainless steel or special alloy materials can resist corrosion from sulfides and chlorides in flue gas, extending equipment life;

Vibration resistance: Thermocouple components are fixed with high-strength insulation sleeves to reduce the impact of mechanical vibration on temperature measurement stability;

Quick response: Thermocouples have low thermal mass and short response time, which can capture temperature fluctuations in real time and avoid equipment overheating or efficiency decline due to lag.

4、 Standardization and Customization: Meeting Diverse Needs

Shanghai Automation Power Station Thermocouples Strictly FollowIECInternational and domestic industry standards, providingKTheETheTChoose from multiple indexing numbers and support customized design. For example, in response to the high temperature requirements of ultra supercritical units, its products can be expanded to1600℃Temperature measurement range; For space constrained scenarios, miniaturized probe designs can be provided. In addition, the company also provides diversified installation methods such as flange connections and tapered pipe connections to ensure seamless compatibility with existing power plant equipment.

5、 Economy and reliability: reducing full lifecycle costs

Compared to imported products, thermocouples for Shanghai automated power stations not only ensure performance but also reduce costs20%-30%And the maintenance cycle has been extended to5Years or more. Its passive sensor design does not require an external power supply, further reducing the complexity of operation and maintenance. at some point60In the application case of a 10000 kilowatt generator set, this series of products operates continuously3No malfunctions occurred in the year, temperature monitoring data andDCSThe system is highly compatible, helping the power plant save over a million yuan in spare parts replacement costs.

Conclusion

From high-temperature and high-pressure steam pipelines to precision turbine monitoring, Shanghai Automation Power Station thermocouples“Wide temperature range, high precision, strong adaptability, low cost”The core advantage provides a reliable temperature measurement solution for the power industry. With the development of smart grids and clean energy, their products will continue to iterate and upgrade, helping power plants achieve more efficient and safer operation and management.
