Analysis and treatment of common abnormalities in zinc oxide arrester manufacturers

Analysis and treatment of common exceptions:

The leakage current meter is zero. The possible reasons for this phenomenon are:

(1) The meter indication fails,

(2) Short-circuit the ammeter with the shielded wire.

(1) Treatment: Tap the meter with your hand to see if it is stuck, and if it cannot be recovered, you should add a missing form, repair or replace it.

(2) Handling: Use a lingke bar to pick up the place where the shielded wire and the conductive part of the arrester touch, and it can be restored to normal.

Leakage current meter indication is too large:

Analyze based on historical data. If it is found that the meter is fully loaded, it should be judged that there is a problem with the arrester, and the arrester should be reported to the dispatch immediately, and the arrester should be taken out of operation, and please inspect it.

The porcelain bushing of the arrester ruptured and discharged. In the case of power frequency, the porcelain bushing of the arrester is used to ensure the necessary insulation level of the arrester. If the porcelain bushing ruptures and discharges, it will become a hidden danger of the power system. In this case, it should be stopped and replaced in time.

There is discharge sound inside the lightning arrester (lightning arrester manufacturer, European-style cable connector, cold-shrinkable cable terminal). In the case of power frequency, there is no current through the arrester. Therefore, there should be no sound. If there is an abnormal sound in the arrester during operation, it is considered that the arrester is damaged and has no effect, and single-phase grounding may be caused. In this case, the dispatcher should be reported immediately, and the arrester should be taken out of operation and replaced.
