Problems solved by technology
[0003] At present, the domestic testing of containment sealing performance is based on the ideal gas state equation and the least square method, in which the measurement of the absolute pressure inside the containment, as a direct influence parameter in the containment sealing test, is used in complex work Under the environment (such as construction near the pressure gauge storage area during commissioning or test preparation or test), non-fixed instruments and unprotected instrument wiring often cause equipment wiring failures and signal acquisition due to accidental touches and accidental touches during on-site cross-work. Interruption, resulting in a large error in the measurement, which in turn leads to the failure of the containment tightness test

The invention belongs to the technical field of nuclear power plant pressure measurement, and specifically discloses a nuclear power plant containment sealing performance test pressure measuring device. The nuclear power plant containment sealing performance test pressure measuring device comprises a sensor body protection device, a sensor electrical junction box and an upper computer control system, wherein an output end of the sensor body protection device is connected with an input end of the sensor electrical junction box; an output end of the sensor electrical junction box is connected with an input end of the upper computer control system; a sensor in the sensor body protection device measures to obtain a pressure signal of static pressure in a nuclear power plant containment, and transmits the pressure signal to the sensor electrical junction box; and the pressure signal is transmitted to the upper computer control system, and the upper computer control system processes and digitally displays the pressure signal. The nuclear power plant containment sealing performance test pressure measuring device can ensure that a pressure measuring system fault risk in the containment overall sealing performance test process is eliminated, and guarantees that the test is conducted smoothly.
Description
technical field [0001] The invention belongs to the technical field of nuclear power plant pressure measurement, and in particular relates to a pressure measuring device for a containment test of a nuclear power plant. Background technique [0002] In order to ensure the safety of the public and the environment, the containment is the last barrier for radioactive containment in the reactor of a nuclear power plant, and its sealing performance will directly determine the ability of the nuclear power plant to contain radioactive materials. It is an important basis for the ability of the plant to contain radioactive materials. [0003] At present, the domestic testing of containment sealing performance is based on the ideal gas state equation and the least square method, in which the measurement of the absolute pressure inside the containment, as a direct influence parameter in the containment sealing test, is used in complex work Under the environment (such as construction ne...
