Sharp drinkers arising from lightning in the power line or switching failures can output power supplies and, even worse, operating electronic device modules.
Combined DS130VG Series Protection Device. Type 1 + 2 + 3 is intended for installation in the introductory, distribution and floors of electrical panels with an average and low risk of lightning currents.
Prevent similar troubles help pulsed overvoltage protection devices.
Install the ultrasound in the existing network is easy (usually mounted on a DIN rail, and in the chains they should be located after the circuit breakers), but the device must be connected to the ground circuit. When it triggered, it "will drop" the impulse in the network. The uzip is different sensitivity and are divided into three types.
Uzip DLAS-48D3 to protect telecommunications equipment and data lines
Supports of type 1 withstands the maximum pulses arising when zipper in lightning lights or high-voltage wires next to the house, but not completely "extinguished" them; Uzip 2 is more sensitive, but a strong impulse will burn them, and the house will be de-energized, so the Uzip 2 is mounted after the Uzip 1. Uzip 3 is designed for individual circuits and should be installed as close as possible to electrical appliances. Thus, the reliable protection and uninterrupted operation of electronics provides only a "cascade system", consisting of the ultrasound of different types.
Introductory electrical panel 15 kW 380 V with meter, uzip, UzO and automatic switches
Important parameters for all uzip are also:
UC is the largest lengthy voltage. It must be 10-20% higher than the nominal working voltage in the power grid.
Up - protection level. For devices of the first stage of protection - at least 2 kV, the second is 1.5-1.2 square meters.
TA - response time. For devices of types 1 and 2, it should not exceed 100 ns, for type 3 - 25 ns).
OVR T2 70-275S P TS Limiter, Type 2, price - from 7500 rubles.
The cost of the development of well-known brands starts from 7 thousand rubles, and the system of internal lightning protection of medium reliability taking into account the installation will cost 14-30 thousand rubles. With difficulties with its design, it is better to contact the manufacturer directly into the manufacturer's office, capturing with you the wiring scheme at home.
DUT250VG compact uzip (type 1 + 2 + 3) for a three-phase network - from 33 thousand rubles.
