Guantanamo1000 KVA power dry-type transformerA few tips to improve efficiency

On load commissioning:The method and whole process of taking oil sample of power transformer are as follows:Guantanamo,Accurately measure the resistance of each phase winding and carry out the measurement. If there is a great difference, 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.In terms of the place of use, and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;Jiutepec,After no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.After the oil is drained, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.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.

Operation and maintenance management of oil immersed transformerThe transformer manufacturer will introduce the efficiency of the transformer to youWhat about oil immersed transformer fire?analysis,Causes of fire in power transformerThe 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,Guantanamo200 KVA dry type transformer, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.Oil leakage at looper flange

Oil leakage at looper flangeThe cost is reasonable,For no-load impulse closing of transformer, pay attention to the following matters:After the power transformer has been used for a long time, common faults of iron core will occur. Don't worry. Contact the transformer manufacturer, and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:& ldquo; YN, D & rdquo;, in which indicates that when the working voltage phasor of the primary side line as the minute hand, refers to the position at o'clock, the phase voltage phasor of the secondary side is at o'clock. That is, the phase voltage UAB of the secondary side lags degrees behind the working voltage uab of the primary side line (or degrees ahead).Guantanamo,The hanging core of dry-type transformer is a vital partIn the case of dry-type transformer operation there is more noise, and some even cause noise,GuantanamoLoss table of distribution transformer, which seriously endangers everyone's no problem rest time and work. At this time, the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.Oil leakage of heat pipe radiator
