TL;DR: In this paper, a detection method of airtight leakage points of a large electrical module container is presented, which includes the following steps of installing an oxygen concentration detector in a wall body which is located on the upper portion of the container, installing air pressure sensors inside and outside the wall body, and installing a computer which is used for receiving data of the oxygen concentration sensor and the air pressure sensor outside the container; enabling a carbon dioxide gas station and a methane gas station to communicate with an air inlet formed at the bottom of a container through an air-inlet pipe respectively
