Abstract

The invention discloses a lightning current impact test method. The method comprises the following steps that: a function button module acquires a lightning current impact request set by a user and outputs the obtained lightning current surge request to a lightning current generating device, wherein the lightning current impact request includes a charging control signal; the lightning current generating device generates a lightning current wave with a certain voltage value according to the lightning current impact request and outputs the lightning current wave to a surge protector so as to carry out lightning current impact testing on the surge protector; and an indicator lamp indicates a lightning current impact test result after the surge protector receives the lightning current wave impact. Therefore, the protection effect on the equipment by the qualified surge protector under the lightning current impact can be observed visually and thus one surge protector not meeting the specification can be screened rapidly and accurately.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a lightning current impact test method. Background technique [0002] Surge Protective Device (SPD), also called lightning protector, is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When the electrical circuit or communication line suddenly generates a peak current or voltage due to external interference, the surge protector can conduct the shunt in a very short time, so as to avoid the damage of the surge to other equipment in the circuit. [0003] In GB18802.1-2012, IEC61643-1, UL1449 and other specifications and standards, the surge protector must be tested by lightning current impact, that is, a lightning current generator is used to generate an 8 / 20μs lightning current wave to test the surge protector. Lightning impulse test. [0004] The current lightning current impact test method ca...
