Nanyang Teflon power and low voltage cabinet hanging cabinet grounding system installation fabrication and installation (1) Ground network should be strictly in accordance with the "electrical installations engineering construction and acceptance of grounding devices" (GBJ50169-92) performed. (2) The grounding burial depth should meet the design requirements. When not specified, not less than 0.6 meters. Angle iron, steel, copper and other vertical grounding should be laid. In addition to the ground inside and outside the body, grounding lead and ground means of the vertical part of the connecting portion 10 cm range should be embalmed; and to remove rust and welding flux residue thereof. In the ground wire may suffer mechanical damage place, apply pipe or angle iron to protect them. (3) ground through the joints of the building, such as the use of welded and fixed distribution cabinet, the ground should be made of curved through a period of expansion joints. Make sure (4) between grounding firmly welded between the ground wire or ground wire to the electrical device during lap welding, welding should be carried out in addition to contacts on both sides, but also on the steel bent arc welding shaped (or rectangular-shaped) and steel (or angle) welding. From the steel strip (or angle) should be top 100mm distance. (5) The length of the lap weld shall meet the requirements: flat steel and flat steel lap twice the width of flat steel distribution cabinets Nanyang price of not less than three welding; round and round the lap round 6 times the diameter of the steel, double-sided welding; round and flat round lap six times the diameter of the Nanyang distribution cabinets over and over again, double-sided welding; flat steel and steel, flat and angle steel welding, tight affixed to the outside of both sides of the angle, or close to the outer most surface of the steel pipe, welding upper and lower sides. (6) grounding Deng County distribution cabinet construction is completed, should be ground resistance testing, resistance size to meet the design requirements. Teflon high and low voltage power distribution box to check the power cabinet distribution cabinet distribution cabinet will be transferred to the construction site to check out of the box first before construction, has three purposes, one: Inspect the electrical cabinet Model specifications meet the design requirements, cabinet body exterior is intact; Second: check the internal components are in good condition; Third: detailed check based on the number and distribution cabinet design diagrams, and installation location, as well as to determine the compatibility of the cabinet, the cabinet circuit and wiring Whether neat, in line with the relevant regulatory requirements.
