Teflon packed after a power transformer on the electrical test, and package delivery testers packaged by a company specializing in personnel selection packaging according to transport distance and road conditions. Transmission test voltage is first put into operation, it can impact the total pressure distribution cabinets Nanyang closing price, closing at impact can generally be put into the high-pressure side. After receiving the first power transformer, the duration of not less than 10min, no exceptions. Transformers should be 3 to 5 times the total pressure shock closing, no exceptions, should not cause inrush current protection device malfunction. Note that the test run transformer inrush current, load current, a secondary voltage and temperature. And make detailed records. Transformer no-load operation 24 hours, no exceptions Nanyang distribution cabinets over and over again, the load can be put into operation. Nanyang Teflon high and low voltage distribution cabinet installation and construction (1) basic steel Installation 1) by drawing prefabrication base steel frame, and make embalmed Deng County distribution cabinet, according to the construction drawings of the target position, the prefabricated steel frame on the reserve on the basis of iron distribution cabinets, leveling, alignment after the foundation steel frame, embedded iron parts, gaskets by welding in prison. Top of the foundation should be higher than the final steel smooth surface 10mm. 2) Basic steel Ground: basic steel After installation, you should ground both ends of the base steel weld, weld surface is twice the width of the flat steel and reliable connection and earthing arrangements. And good corrosion protection. Deng County distribution cabinets, distribution cabinets, power is supplied by the Nanyang Fulong Fulong Power Engineering Company Limited. Nanyang Fu Long Electric Power Engineering Co., Ltd. (www.nyfulong.com) strong, credible, Nanyang in Henan transmission equipment and materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Teflon electricity into the brilliant and you work for a better future!
