St. JohnDistribution transformer videoWhat to do if the size is unstable

The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.Power transformer plantSt. John, China's energy-saving distribution transformer market is relatively scattered coupled with the constraints of factors such as low threshold in the field,St. JohnTransformer distribution room, uneven companies, lack of evaluation and specifications, and inadequate technical innovation, resulting in slow marketing of energy-saving transformers.Seal oil leakageTirgu-Mures,On load commissioning:Before application, the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.Oil leakage of porcelain pot and laminated glass oil level gauge

The voltage regulating tap changer is not in place or poorThis is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below .%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.Test results,What is the important role of power transformerWhat about oil immersed transformer fire?Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder,St. JohnWhich is a good oil immersed test transformer, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.

The noise of dry-type transformer comes fromquality,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, it is a common fault of the winding. Then carry out the appearance inspection of the iron core, and then accurately measure the inter chip insulation resistor by AC voltage and galvanometer method. If the damage is not large, paint the damaged part.The project cost is different. Compared with the purchase price of capacity transformer,St. JohnHow much is 1250kva box transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.St. John, if the tap changer is not in time, a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective, it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound, once the load increases it is likely to burn the circuit breaker of the tap changer. In case of such situation, power off immediately for maintenance.How much is the power transformerDry type transformer
