Testing device for measuring internal leakage of multi-area space

Abstract

The invention discloses a testing device for measuring internal leakage of a multi-area space. The method comprises at least two test spaces, an air supply system, an air exhaust system, an exchange system and a monitoring control system, wherein the air supply system comprises an air supply fan, an air supply pipe and a first connecting base, the air exhaust system comprises an air exhaust fan, an air exhaust pipe and a second connecting base, the monitoring control system comprises differential pressure gauges, hygrothermographs, flowmeters, valves and a computer, a first connecting base and a second connecting base are mounted on each test space, one end of the air supply pipe is communicated with the air supply fan, the other end is communicated with the test spaces to ensure that positive pressure is kept in the test spaces, one end of the air exhaust pipe is communicated with the air exhaust fan, the other end of the air exhaust pipe is communicated with the test spaces through the second connecting base, air flow in the test spaces is ensured, one differential pressure gauge and one hygrothermograph are arranged outside each test space, and one flowmeter and one valve are arranged on each air pipe, so that the change of gas in each test space can be monitored, and the accurate measurement of the internal leakage of the master control room is ensured.

Description

technical field [0001] The invention relates to the technical field of test devices, in particular to a test device for measuring internal leakage in a multi-area space. Background technique [0002] The main control room of the nuclear power plant is the operation control center of the nuclear power plant. Its function is to ensure the safe operation of the reactor under normal conditions, and to have the ability to deal with design basis accidents when the reactor is shut down safely under abnormal and accident conditions. During a nuclear power plant accident, in order to enable the personnel in the main control room to stick to their posts and alleviate the consequences of the accident, it is necessary to ensure that the main control room has a certain degree of habitability. When evaluating the habitability of the main control room, the measurement of the internal leakage of unfiltered air entering the main control room is a key factor. [0003] In my country, the test...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the leakage measurement technologies in the main control room of nuclear power plants in the world are internal leakage measurement in a single area, and there is no report on the related work of leakage testing in the multi-area range of the main control room of nuclear power plants.
