    15kV Zinc Oxide Surge Arrester , Polymer Lightning Arrester For Protection

    HY5W-15/42Zinc Oxide Arrester with Electrical Switchgear Euipment


    The lightning arrester is sometimes also called the overvoltage protector, the overvoltage limiter.The arrestor is connected between the cable and the earth, usually in parallel with the protected equipment. The lightning arrester can protect communication equipment effectively. Once abnormal voltage appears, the lightning arrester will act to protect. When a communication cable or device is running at a normal operating voltage, the lightning arrester does not work and is considered to be broken on the ground. When a high voltage occurs and the insulation of the protected equipment is endangered, the lightning arrester moves immediately to direct the high voltage shock current to the ground, thus limiting the voltage amplitude and protecting the insulation of the communication cables and equipment. After the voltage disappeared, the lightning arrester quickly returned to its original state, making the communication line work normally.

    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.
