Noise solution of dry-type transformerThe power transformer belongs to relatively durable electrical equipment,DaventelRecycling power transformer manufacturer, 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:Daventel,Power transformer is indispensable for power stations and substations, and the selected structures and connections are also different. Then, 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.Bayamare,When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:The noise of dry-type transformer comes fromDifferent diversion methods, dry-type transformers mostly use silica gel waterproof casing, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.Under normal conditions, different oil-based oils cannot be mixed. Under special circumstances, if it is necessary to use new oil of different grades, and then the oil mixing test should be carried out.(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.Honesty and mutual benefit,Falling foreign matters and piercingWhen the full load test is carried out and everything is normal, the load can be connected.Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core and long-term scalding of iron core will lead to insulation aging.
Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.Range,Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.The equipment can eliminate the shortcomings found in the patrol inspection, clean the porcelain waterproof casing casing, remove and replace the cracked or brittle leather pad check and tighten the node, replenish the oil with less oil,DaventelOverload capacity and time of oil immersed transformer, check and replace the silica gel of the breathing mask,DaventelOil immersed transformer capacity, etc.Dry type transformer manufacturerDaventel,After the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection, or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, the generator set must be disassembled first.
