Reason porcelain insulators appear in the actual use failure

    Porcelain insulators in use, often appear some symptoms, need to be kept clean and tidy electrical insulator surface, according to certain ways and certain of its maintenance and repair to ensure the electrical insulator in the use of the tremendous role and value.

    Porcelain insulators often occur in the use of some failure, problems need to be resolved and maintenance, to ensure the porcelain insulators play an important role and value in use, to fuse anatomical analysis of electrical porcelain, porcelain insulators in the middle of the hollow column All discharges caused by free black carbonized material, analysts believe may be the top terminal Mifengbuyan porcelain insulators, leakage of rainwater through multiple sets of test no sign of leaks, sealing well prove two conductive breakdown and rain Erosion irrelevant.

     Porcelain insulators failure also may be due to the internal insulation porcelain insulators hollow barrel, after interference by the strong electric field destroys the balance of media power in the air, resulting in discharge breakdown, which is the manufacturer in the manufacturing, test engineering, the porcelain insulators He made a hollow in the middle due to the phenomenon, affecting the life and value of real porcelain insulators. But the center of untreated vacuum space, so that residual air in the role of a strong electric field forces, after a long period of ionization in the hollow conductive film formed on the surface, that is ionized carbon with a long running time, the current increases, then encountered strong thunder current, over-voltage, destroyed the balance, eventually leading to the insulator breakdown conduction.

     Analyzing results from the analysis, although before installation made of porcelain insulators electrical test, but can not guarantee the safe operation of the equipment. Because ionization produced carbon is charged after a long run formation. It also reminded the majority of the operating personnel, repair and maintenance work on the device, you must strictly enforce safety procedures when working on high voltage equipment, safety organizational measures must fulfill, after safety technology, work can be carried out, in particular, should be prepared to blackout , examine the electrical, installation of operating procedures for the ground wire.
