Falling foreign matters and piercingIt will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.San Pablo ,It should be said that after the development trend of these years the overall level of China's transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.Orastie,kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder, and the insulating paper cylinder is installed on the wooden frame. The actual operation rocker is connected with the dynamic circuit breaker of the tap power switch according to the wooden insulating rod. The on load tap off power switch is insulated from the ground by the insulating paper cylinder of the power switch itself and the insulating limit.In the electric field of the winding to the yoke,San Pablo 10kV distribution transformer, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, so as to reduce the electric field component intersecting with the insulating parts.The method and whole process of taking oil sample of power transformer are as follows:

In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?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).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?Quality inspection report,(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.What is the important role of power transformer

Deterioration damage of transformer core insulationFocus on Development,Dry type transformer factoryOil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding,San Pablo Main components of oil immersed transformer, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, that is, the disconnection component of the electric field is small.San Pablo ,Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.Common problems of tap changer of power transformerUnder normal conditions, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems
