HY10W-9/30 Zinc Oxide Arrester with Electrical Switchgear Euipment
With the emergence of new equipment and new testing methods, it is possible for the lightning arrester to carry out both electrically tested conductance current and electrically tested infrared temperature. In order to ensure the reliable operation of the lightning arrester, the new operation of lightning arrester within 3 months, and the annual Qiujianshi, should be in accordance with the rules of the general test, and the data records of the general test records, for the next test for comparison, which is conducive to the detection of stable problems.
Using infrared thermal imager to measure temperature, we can measure the small change of temperature and compare the difference of surface temperature of lateral flange or porcelain cover. If the temperature deviation is large, that is, the lightning arrester may have defects, must be further checked, until the reasons for the exclusion or replacement can be found to be able to hang. An electrical appliance used to protect electrical equipment from high transient overvoltage damage during lightning strikes, and to limit the duration of continuation, and often the duration of continuation. The lightning arrester is sometimes also called the overvoltage protector, the overvoltage limiter.
