Nanyang transformer installation (two) arrester ground deflectors should: Using bare wire, copper wire: ≮16 mm; steel wire: ≮35 mm; (P209 aluminum 25 mm2) E, valve type arrester ground deflectors and the equipment to be protected with metal casing should be reliable grounding grid connection Nanyang electrical installation works, "Trinity" ground installation; 7) Single line valve arrester Nanyang Power Engineering Company, grounding resistance grounding device should be less than 5Ω; 8) lightning deflectors susceptible to mechanical damage in the place, on the ground floor of about 1.7m to 0.3m in the period under deflectors should be protected facilities. 3. There are several outdoor transformer installation method? General requirements for the installation of its own regulations? A: The transformer is installed in the form of outdoor installation: a seasonal outdoor installation of transformer station, also known as outdoor variant, can be divided into the stage (ground) to install and column (pole) installed. 1) There pole mount but should not exceed the capacity of 315KVA; rural installation of transformers is not less than 2.8 meters from the ground, the city installed transformer is not less than 3.5 meters from the ground; 2) transformer capacity becomes limited ground station installation. Nanyang Teflon power transformer construction steps: 1, clean the casing, check whether the discharge traces porcelain sets and breakage. Check the wiring lead casing bolts are loose, if the joints overheating. 2, cleaning the transformer tank and the conservator, safe airway pressure regulating device purifiers and 3, and the conservator of the transformer tank cleaning, security airway pressure regulating device purifiers and other accessories. 4, check the safety of airway proof membrane is intact, remove the pressure relief valve cover dust deposition, product material and other debris. 5. Check the oil level is normal conservator Nanyang electric power engineering construction team, the oil level gauge (oil level gauge) is intact, clean, and the oil discharge sewage collection basin. 6. Check the respirator and replace failed discoloration desiccant. 7, cleaning the cooling system and check whether the oil leaking radiator, cooling fan, oil cooler or without oil leakage, water leakage. 8. Check whether the oil leaking gas relay, opening and closing the valve is flexible, reliable, and control cable insulation is good. 9, test measuring top oil thermometer. 10, check processing transformer enclosure ground wire and neutral grounding devices. 11, check on-load tap operation control circuit, transmission parts and contact action cases, and cleaning operations inside the box. 12, from the transformer body, filled bushing and oil samples taken within purifiers do all by Paul simplify testing.
