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.
