Three phase power supply, lightning protection, surge protector,
box type, lightning counter, indicator lamp
Brief introduction
The three phase power supply lightning protection box is used for
lightning protection of 220/380V distribution system, so as to
protect the equipment from damage caused by lightning overvoltage
along the power line. It is mainly installed in distribution rooms,
distribution cabinets, AC distribution panels, switchgear boxes and
other important equipments, which are easily subject to lightning
incoming power supply.
Working principle of product
n the normal working condition, the lightning protection module is
in the disconnected state and does not affect the normal work. When
the line has the impulse overvoltage at the moment when the
lightning strikes, the lightning arrester module quickly passes
through the very short time, short the overvoltage to the earth,
and when the pulse overvoltage disappears, the lightning arrester
module is resumed to disconnect. State, which does not affect the
power supply of the user.
Product features
1. double power supply system, up and down access structure.
2. using the latest arc extinguishing technology to avoid fire
completely
3. with the power status indicator, indicating the working state of
the lightning protector.
