Yueqing Lei Chung electrical production and operation OBO, ABB, Schneider and other series surge protector for sale, cheap, large favorably, welcome advice to buy the pro, can also be customized. First, the use of lightning arresters electrical one, is one of the widely used electrical. For arresters we all know some, this is not the lack of high-rise buildings. Arrester similar harmonic elimination, divided into many. CHINA Electrical boutiques to introduce you to several of the arrester model. Distribution arresters: used to protect distribution transformers, switchgear, box-type variable, cable head column switches and other small oil distribution equipment from atmospheric over-voltage and over-voltage damage. Plant arresters: used to protect power plants, substations equipment from atmospheric over-voltage and over-voltage damage. Parallel compensation capacitor arresters: vacuum switch for suppressing or less oil switch capacitor switching overvoltage generated renewed protect the capacitor bank from operating over-voltage damage. Its use: Ambient temperature -40 ℃ - + 40 ℃; altitude less than 2000m; power frequency 48Hz- 62Hz; seismic intensity of 7 degrees and the following areas; maximum wind speed does not exceed 35m / s; long applied to the arrester work frequency voltage should not exceed its continuous operating voltage.

First, classification and selection arrester arrester selection. From the actual use of the situation, lightning damage in most cases is due to the lightning arrester action is too often result, and this part is because of lightning caused by improper selection, so the correct selection of the security lines and equipment to crucial. Arrester selection of the most important is the nominal voltage selection: should make it higher than it might appear during the installation of the power frequency voltage transients. In llOkV and above the neutral point grounding system can be selected as described above. Second, the installation of a newly installed lightning arrester, said selection requirements should first check whether its voltage level is consistent with the protection device. The first two new clothes and re-install (no thunder of decommissioning) must be measured frequency AC and DC voltage test leak test and insulation resistance up to standard requirements can not be used. Top 3 installation, you should check the arrester is intact. Its surface should be no cracks, no damage; seal should be intact, should be closely connected; metal contact surfaces should be cleared of the oxide layer, dirt and foreign matter, to protect clean. Third, the maintenance of the arrester (a) preventive tests. Working for many years under the combined weather conditions, electrical and so on. Arrester performance may change, in order to detect potential safety problems, the arrester to deal runs until the advent of the thunderstorm season for preventive tests. (B) visits to check the arrester. 1 Check the appearance of damage, cracks, contamination and discharge phenomenon. Because the damage, cracks, contamination in the humid air, under applied voltage, leakage current will significantly increase the arrester appearance, reduce the discharge voltage. After 2 each thunderstorm lightning counter to check whether the action, check lightning counter is intact. 3 Check the terminal fitting is solid, the lead is disconnected, broken stocks, burned traces. 4 Check abnormal sound inside the arrester. 5 Check the arrester mounting loose. Fourth, hazards and hazardous mine tips lightning hazards caused by different forms of lightning and other factors, it is lightning fast attacks, before people had not heard thunder shock, but too late to escape. Moreover instantly struck by lightning caused buildings, warehouses, depots and other fire and exploded, causing enormous material and human losses and casualties. Although it has increased awareness of the lightning, and take some lightning protection measures, however, lightning involves many uncertainties, although we generally determine the lightning discharge behavior of a particular form, but can not guarantee that will not deviate from this form of lightning discharges so lightning is a very important fire safety measures. When a lightning storm should avoid entering and proximity: without the protection of small buildings, warehouses, sheds and the like; not take lightning protection tents and temporary shelters; non-metal roof or hood of the car; open fields, playgrounds, swimming pool, lake and waterfront, barbed wire, clothesline, overhead lines, isolated trees. Avoid using or touching electrical equipment, telephones and plumbing fixtures, as soon as possible and taken refuge: Take lightning protection measures for residential and other buildings; underground shelters, subways, tunnels and caves; large metal or metal frame structure; a metal Cars and other vehicles closed roof. We should seek to avoid low-lying areas and upland hill, look for dense woods. If you are in an exposed area, alone, when the lightning comes, you feel the hair put up, indicating that the lightning, you should immediately squat body bent forward, and hands on knees. Do not lie flat on the ground, nor put his hand on the ground.
