Falling foreign matters and piercingIn relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuitBaldjov,Principle of step-up dry-type transformer: the step-up dry-type transformer is a component that correspondingly converts low communication AC voltage, large current flow and small characteristic impedance into high communication AC voltage, small current and large characteristic impedance. When there is an AC circuit in the original coil, the communication AC magnetic flux will be caused in the transformer core (or magnetic core), causing the magnetic induction voltage in the primary coil (or current).Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations, It is used to carry out insulation compressive strength test under required current for various electrical products electrical components and insulating raw materials.Barika,Wiring mode of dry-type transformer: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:The power transformer conductor refers to the connecting transmission line between each electromagnetic coil,Baldjov500 KVA oil immersed transformer, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.

Generally speaking, 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.First of all, although dry-type transformer has strong moisture resistance, it is generally open structure or very susceptible to moisture, especially the insulation level of dry-type transformer manufactured in China is low (lower flame retardant grade) Therefore, the dry-type transformer can obtain high stability only when the air humidity is below %. The dry-type transformer shall also be prevented from stopping operation for a long time to prevent serious damp. When the grounding resistance value is less than / V (operating voltage), it indicates that the transformer is seriously damp, and the trial operation shall be terminated.When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent,BaldjovOil immersed regulator, 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:Quality risk,BaldjovQuotation for oil immersed transformer,Deterioration damage of transformer core insulationOverload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation, which dissolve and ignite, resulting in a lot of steam bodies, greatly increasing the internal working pressure of the power transformer, causing the ignition of the casing, causing large-scale power failure, endangering all normal production, manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.

The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?market price, platinum thermistor (pt) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer stop the cooling centrifugal fan, set up common problem alarm, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.Visual inspection method for transformer inspectionAnalysis of common faults of oil immersed transformer:Baldjov,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.In relay protection dry-type transformer, the disconnection of the fault point is related to each other.
