Shielding effectiveness test method and device, electronic equipment and storage medium

The invention discloses a shielding effectiveness test method and device, electronic equipment and a storage medium, which are used for solving the problem that a protection scheme cannot be correctly selected due to the fact that a test result is not accurate enough when shielding effectiveness quality analysis is carried out in the prior art. The method is applied to a shielding effectiveness test system, the shielding effectiveness test system comprises an electromagnetic pulse irradiation device, a terminal box and a shielding cabinet, and the terminal box is connected with the shielding cabinet through a cable. The method comprises the steps that an electromagnetic pulse irradiation device is adjusted, so that the output electric field of the electromagnetic pulse irradiation device at a terminal box and a shielding cabinet is kept within a preset numerical value range; recording internal and external electric field measurement data of the shielding effectiveness test system, and respectively calculating
