Electric vehicle charging pile (station), the lightning protection should be low voltage into line in the transformer room ark of the Lord, distribution, electrical cabinets and charging internal classification set surge protector, when subjected to lightning overvoltage discharge lightning current surge protector through layer upon layer, step by step, discharge, will eventually be transient overvoltage amplitude to clamp down on charging pile (station) normal voltage range, so as to realize the charging piles lightning protection and electric vehicles.
Les, launch a photovoltaic dedicated surge protector. Photovoltaic power surge protector in a high impedance state under normal circumstances, when the system overvoltage, les, LM - PVD surge protector series photovoltaic dedicated nanosecond conduction, transient energy through the grounding line is introduced into the earth, and the amplitude of voltage to clamp down on the safety of the equipment within the normal range, at the same time, the transient energy through the grounding line is introduced into the earth. Transient energy after discharge, surge protector quickly recover high impedance state, so as to guarantee the normal work of the photovoltaic system.
In the fourth session of wind power development enterprise leaders symposium, energy bureau said the next step will be in "three north" area to improve capacity and on-site given to be delivered to the outside, optimization of wind power base, standardized development; In combination of hydropower development in southwest China, water, wind, light as a whole and promote comprehensive base development; In the key to promote wind power development on the spot or in the vicinity of southeast, especially in the rural "thousands of villages and townships in controlling wind project", etc. The personage inside course of study says, "wind power to the countryside"
Overview of the scheme is used to Ann (city) video monitoring system of lightning protection engineering, city and country video monitoring system of lightning protection lightning protection, public security video monitoring system, outdoor room lightning protection monitoring system, monitoring center, factory enterprise perimeter prevention system lightning protection, bank securities hospital monitoring engineering system lightning protection %
Installed in LPZ0BZ and LPZ1 grade I (i.e., B / 1) LM - KB255-25 type surge protector, on the border of LPZ1 and LPZ1 zone installation level II (grade C \ 2) LM - XC385-40 type surge protector, in the LPZ2 front-end equipment installation level III (grade D/level 3) LM - XD275-20 surge protector. Class I used for the power distribution cabinet (box) location; Class II for distribution box; Level III for distribution box and the need to protect the electronic information equipment port.
Point is the feature of highway electromechanical system, area wide, long line, both high voltage equipment, and a large number of monitoring, communication, sensing and other weak current equipment, the wilderness areas often have prominent equipment, power lines are mountains, transmission and control circuit are often through complicated geological level, these are vulnerable to lightning or thunder and lightning induction vulnerabilities.
