Abstract

The invention discloses a follow-up current breaking test system, relates to the field of switch lightning protection devices, and aims to solve the problem of testing the follow-up current breaking capacity of an existing switch type surge protection device. The system comprises an isolation transformer, a silicon controlled rectifier triggered thunder and lightning discharging device, a thunderand lightning generation\Uc\lightning protection device assembly workbench and a thunder and lightning generation device, wherein the isolation transformer is used for respectively outputting 220V electricity to the thunder and lightning generation\Uc\lightning protection device assembly workbench, the thunder and lightning generation device and the silicon controlled triggered thunder and lightning discharging device through isolation, the output end of the thunder and lightning generation device is electrically connected with a switch type surge protection device arranged on the thunder andlightning generation\Uc\lightning protection device assembly workbench, the output end of the lightning protection device is connected with the silicon controlled rectifier triggered thunder and lightning discharging device, and the silicon controlled rectifier triggered thunder and lightning discharging device is used for discharging thunder and lightning.

Description

technical field [0001] The invention relates to the field of switch lightning protectors, and in particular to a test system for subsequent current after interruption. Background technique [0002] At present, a considerable part of the first-level power surge protectors (English: Surge Protection Device, abbreviated: SPD) used in the lightning protection market are switch-type surge protectors. Although the switch-type surge protector has the advantages of large current capacity, low residual voltage and long service life, it is prone to accidents such as combustion, explosion and non-action due to problems such as subsequent current and ignition voltage of the switch-type surge protector. and problems, especially in the communications industry. Due to the freewheeling problem of switch-type surge protectors, many industries, especially the communication industry, have taken some measures to restrict the use of switch-type surge protectors.
