Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a temperature sensor component for a natural gas power plant. Background Art

[0002] Natural gas power plants mainly use natural gas to generate electricity. Traditional coal, oil and nuclear power generation methods have great defects, cannot make full use of natural gas resources, and have high carbon dioxide emissions. With the change of energy structure, natural gas power generation has attracted more and more attention. The gas turbine generator set uses gas cooling to drive the steam turbine generator to generate steam pressure and pressure to drive the turbine rotating shaft to drive the impeller to rotate and compress the air in the atmosphere to the bottom of the impeller to form a centrifugal field. Due to the interaction between the turbine blades, the steam pressure is kept stable, so a large energy output power can be obtained by the reverse action on the blades. At present, many large natural gas power plants have been established in the world. Their advantages are that they can not only effectively save energy, but also have good environmental benefits. In the work of natural gas power plants, the temperature of the working process is particularly important, and temperature sensor components are usually required to detect the real-time temperature.

[0003] However, the existing temperature sensor components for natural gas power plants have the following disadvantages:

[0004] (1) The temperature sensor is directly installed in the working area. The operation of the external device may generate certain vibrations. Long-term vibrations may cause damage to the sensor.

[0005] (2) The signal lines carried by the temperature sensor are mostly placed directly on the surface of the working area. Leaving them there for a long time will cause damage to the signal lines, making the sensor difficult to use.
