LalibertadFunction of oil immersed transformerSignificance of research and development in the practical field

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.

Noise solution of dry-type transformer

Lalibertad.Transformer manufacturers generally adopt IP20 protective casing,LalibertadOil immersed power transformer manufacturer, which can avoid the entry of solid dirt with a diameter of more than 12mm, rats, snakes, cats, birds and other animals, resulting in vicious common faults such as short-circuit fault and power failure, and provide a safe natural barrier for the energized part. If the transformer equipment must be outdoors, which can avoid being equally divided with the above IP20 protective effects However IP23 casing will reduce the refrigeration capacity of the transformer, so pay attention to the reduction of its operating volume.

In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?

.If the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails,LalibertadPower transformer recovery, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, use detection equipment to put out the fire immediately. In order not to expand the hazard the fire brigade must be notified.

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, manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.

(5) the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, it shall be installed on both sides of the low-voltage composite insulator, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.

The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment, such as discoloration, deformation, offset, cracking, loosening, ignition smoke, broken strand disconnection, short-circuit fault marks, hanging of dirty things,LalibertadPower supply transformer manufacturer, etching and turbidity, which can be inspected according to the visual inspection method. Therefore, visual inspection is one of the common methods of equipment inspection.

Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.

Welcome calls .The 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.

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?

Oil leakage at electric welding position

Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.

Quality improvement.Power transformer manufacturer

Dry type transformer is a common electrical equipment, which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries, such as variable frequency power supply.

Common problems of tap changer of power transformer

Lalibertad.The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.

The switching power supply lacks one phase of power;

Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.
