NIMDistribution transformer quotationIndustry Technology Industry Change

first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings, wear round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time, the cable wind shall be added on all sides to ensure that the core international body will not be damaged during the whole lifting process. After lifting for mm, stop the lifting,NIMTransformer and box type substation, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal,NIMModel and meaning of oil immersed transformer, lift it again until the bell cover exceeds the relative height of the body, and rotate the crane to place the bell cover on the clean skid.NIM,The grounding resistance of, high voltage and bottom voltage shall not be less than % (m & omega;) of the original value. The difference between the three-phase mean value of winding resistance measurement at the same temperature shall not exceed %,NIMDistribution transformer capacity, which shall not exceed % compared with the last accurate measurement result.Oil immersed transformer companyMariveles,It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well so as to achieve the pressure management of oil leakage.When leaving the factory, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

It includes the performance and main uses of insulating layer materials the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core, cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.Under normal conditions, different oil-based oils cannot be mixed. Under special circumstances, if it is necessary to use new oil of different grades, it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region, and then the oil mixing test should be carried out.Before no-load impulse closing, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.manufacturer,With the rapid development of society and the continuous development trend of computers, the accuracy of calculation conclusions can meet the needs of architectural design, and scientific and reasonable data method is selected, Not only can the current distribution of the oil immersed transformer be clearly defined in the development stage, but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope, which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.Noise solution of dry-type transformerHow to reduce the failure of dry-type transformer?

Dry type transformer manufactureranalysis,After hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.Visual inspection method for transformer inspectionAccording to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.NIM,After hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, drilling stop hole is a good way to remove in-situ stress and prevent widening.The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:
