EPP series AC power lightning protector consists of multiple single
lightning protection chips, which can be freely combined into
single-phase or three-phase protection for different power
distribution systems to prevent damage to low-voltage power
equipment from inductive overvoltage or operational
overvoltage.EPP65T is usually used for secondary protection.
Protection in stages Editorial Podcast
The first level lightning protector can be for direct lightning
current discharge, or when the power transmission line suffered a
direct lightning strike conducted by the huge energy discharge, for
the possibility of direct lightning strikes, must be carried out
CLASS-I lightning protection. The second level lightning arrester
is for the residual voltage of the former lightning arrester and
the induction of lightning strikes in the area of protection
equipment, for the former level when a large lightning strike
energy absorption, there is still a part of the equipment or the
third level lightning arrester is quite huge energy will be
transmitted, the need for the second level lightning arrester to
further absorb. At the same time, after the first level of
lightning protector transmission line will also induct lightning
electromagnetic pulse radiation LEMP, when the line is long enough
to induce lightning energy becomes large enough to require the
second level lightning protector to further implement the lightning
strike energy discharge. The third level protector protects the
LEMP and the residual lightning energy that passes through the
second level protector [1].
Staged protection
This series of surge protector device(SPD)is suitable for new energy solar power generation system, and the maximum continuous working voltage is DC500V, 800V, 1000V, 1200V. The installation position is in the DC power supply system to protect indirect lightning current, direct lightning current or other transient overvoltage.
