Problems solved by technology

Among them, the temperature sensor assembly is a very important part in the power generation reaction, but the existing temperature sensor assembly usually measures the temperature of the outer pipe wall of the power supply cooling pipe, and the temperature sensor assembly is in a vacuum environment, because the vacuum environment will take away a large amount of Heat, so the accuracy of the measured data is low, the response speed is slow, and it is easily damaged by the high temperature of the power supply coolant, and radiation will be generated during the power generation reaction, and the thermal potential output under radiation will be unstable, affecting the performance of power generation

The invention has the advantages of compact structure, good thermoelectric performance, good radiation resistance performance, good high temperature resistance performance, high reliability, safe and reliable use, and easy popularization.

Description

technical field [0001] The invention belongs to a temperature measuring device, in particular to a temperature measuring armored thermocouple. Background technique [0002] A large amount of heat will be generated during the power generation process, which will affect the normal operation of power generation conditions under high temperature conditions. Therefore, power supply coolant is needed to adjust the reaction temperature of power generation. The temperature sensor component is used to measure the temperature of the power supply coolant outlet\inlet, and the The measured temperature signal is sent to the control system and monitored by the control system to ensure the safe operation of the power generation condition. Among them, the temperature sensor assembly is a very important part in the power generation reaction, but the existing temperature sensor assembly usually measures the temperature of the outer pipe wall of the power supply cooling pipe, and the temperatu...
