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.
