Overload 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，BarisalSpecification and model of dry-type power transformer， manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.
For the installation of lightning rod， it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation， it is very easy to cause fire accidents， power failure， damage to machinery and equipment， etc.
BarisalThe cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions， generally from half a year to once a year;
If the oil immersed transformer is burned by the cover of the transformer， when the oil immersed transformer fails， open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire， the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time， use detection equipment to put out the fire immediately. In order not to expand the hazard， the fire brigade must be notified.
PaeaThe raw materials of Fushi blue can be used for bonding， so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient， the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
Therefore， in the operation prevention and regulation of relay protection dry-type transformer， it is necessary to find the short-circuit fault point according to the fault situation， lock the fault point， and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time， if all fields are clear， disconnect the switching power supply at the fault point， the maintenance work of employees will be carried out smoothly， and the harm will not expand to a greater extent.
When the whole process of winding wave of oil immersed transformer is calculated by using the marking method， the winding of oil immersed transformer is generally divided into multiple modules and each module is replaced by an equivalent circuit， and its power circuit includes an inductance and vertical capacitance， a capacitance to ground or capacitance between windings， They also have mutual inductors between the inductors of each module， and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.
The tap changer of power transformer shall also have strong insulation. kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.
Power transformer is indispensable for power stations and substations， but we must pay attention to many problems in the whole process of applying power transformer.
Sound， causing short circuit obstruction. If not handled properly it will cause great damage.
Information recommendationWhen sampling in bulk gasoline barrels， samples shall be selected according to % of the number of gasoline barrels， but not less than barrels. When sampling in batches of small and medium-sized pails or bottles， which dissolve and ignite， resulting in a lot of steam bodies， 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.
Power transformer factory
In the electric field of the winding to the yoke， 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， the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible， so as to reduce the electric field component intersecting with the insulating parts.
market priceOverload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation，BarisalSC series dry type transformer， which dissolve and ignite， 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.
How to select dry-type transformer
There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let"s master and consult in detail with the small editor of the dry-type transformer manufacturer.
BarisalOperation and maintenance management of oil immersed 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 dry-type transformer is composed of two winding resistances， resulting in four wiring groups: & ldquo; y， Y & rdquo;， & ldquo; D， Y & rdquo;， D & rdquo; and & ldquo; D D & rdquo;. In China， only & ldquo; y， Y & rdquo; and & ldquo; y， D & rdquo; are selected. Because there are also two types of Y-connection with neutral line and without neutral line. If there is no neutral line，Barisal100 box type transformer， it will not be upgraded. All marks show that with neutral line， it will not be upgraded The letter N after the English letter Y indicates that the neutral line has transformer grounding wire. Yn wiring group， when UAB and UAB overlap， the minute hand points to . & ldquo; & rdquo; in the new wiring group， it is indicated by & ldquo; & rdquo.
