Abstract: This application provides a method for box leak detection and a leak detection system, and relates to the field of leak detection technologies. The method for box leak detection may include: filling a box under test with a tracer gas, where the box under test has a plurality of positions under test; and measuring a leak rate at each position under test. Leak detection may be performed on each position under test of the box under test. In this way, not only a specific leak position can be determined, so that leak-proof treatment may be subsequently performed on the leak position in a targeted manner, but also the leak rate at each position under test can be measured, providing a basis for a level of to-be-taken leak-proof measures and whether to take leak-proof measures, thereby improving accuracy of box leak detection.
