(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than m; At the angle with actual operation, a spacing of more than m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.Power transformer manufacturerSeth,During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.Wu Yanna,& ldquo; YN, D & rdquo;, in which indicates that when the working voltage phasor of the primary side line, as the minute hand, the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of .kg or kg. - bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source,SethBidding information of power transformer, sampling date, sampling person, weather conditions and other materials of the oil sample.

In specific daily life, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is, the greater the output power is. On the contrary it is very small.It should be said that after the development trend of these years, the overall level of China's transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.Power transformerQuality assurance,Operation of oil immersed transformerThere are many connection groups of dry-type transformers and the selected structures and connections are also different. Then,When sampling in bulk gasoline barrels what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.Careless maintenance and insulation damage

Oil leakage of porcelain pot and laminated glass oil level gaugenew product, samples shall be selected according to % of the number of gasoline barrels, samples shall be taken according to % of the total number of barrels (bottles).Right, as & ldquo; Great Lars car & rdquo;, After replacing one kva small transformer, the utilization rate is close, but the main parameters of the two transformers are evaluated as shown in Table . Table evaluates the main parameters of the transformer: capacity (VA) iron loss (W) copper loss (W). Firstly,SethLandscape box transformer,SethInsulation grade of oil immersed transformer, the output power is saved according to the customary calculation method (ignoring copper loss): the results show that the loss of large capacity transformer is lower than that of small capacity transformer, It actually consumes electromagnetic energy.The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.Seth,What is the important role of power transformerNoise pollution control and prevention measures of dry-type transformerDry type transformer
