Equipment Lines and Components Thunder Protection Surge Protection
device
Product introduction
The surge protector is suitable for power supply systems such as
50/60Hz 380V and below N-S, NT-C, TH-C, TT and LT. It can be used
as the equipotential connection at the interface of LPZ1, LPZ2 and
LPZ3. The design is based on IEC61643-1 and GB18802.1. The shell is
mounted on the 35mm electric guide. The product has built-in
failure detaching device. When the surge protector overheat and
breakdown, the failure exfoliation device can automatically remove
it from the power grid, and the alarm indicator module is turned
from white (normal) to red (fault).
Working principle of product
Surge protector and its voltage limiting functional element are
composed of metal oxide varistors in parallel. Each varistor
requires an independent disconnector. The principle of the
disconnector is a heat release. The function is disconnected
through the low temperature welding point and is separated from the
metal rod by its own elastic action. After disengagement, the red
indication will appear in the transparent window on the front side
of the surge protector. It is installed in the main power
distribution cabinet and outdoor power distribution cabinet.
Product features
1. Multi function overvoltage protection, lightning overpressure
and other disasters are no longer afraid.
2. Outputting low residual pressure to further ensure safety
3. Limit the precision of the voltage.

Use of attention
1. lightning arrester must be reliably connected to the ground wire
of the lightning protection system, and the connection line is
short, thick and straight.
2. lightning protector should be regularly tested during operation.
If there is any failure, it should be maintained or replaced in
time to ensure equipment safety.
3. ambient air temperature is no more than +40 C and no less than
-5 C, and the average value of 24 hours is no more than +35 C.
