RemchiDry type
RemchiReactor Power transformer plant
When the transformer is out of phase, if the second phase is blocked,RemchiDry type transformer box type transformer, 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:
Remchi.The iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core, its orientation and size change with the change, which promotes the internal molecular structure of the ferrite core to interact with each other, releases energy, and then loses part of electromagnetic energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.
Gradually, high-frequency vibration damping mechanical equipment, 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.
.When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.
In the whole process of transmitting electromagnetic energy in the power supply system, it will inevitably cause the loss of voltage and output power. When transporting the same output power, the voltage loss is inversely proportional to the voltage,RemchiCapacity model of oil immersed transformer, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.
Brief introduction of zero line of power transformer
During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.
Oil immersed transformer operation
Variable cost.Analysis of common faults of oil immersed transformer:
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?
How to reduce the failure of dry-type transformer?
Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, it shall be handled properly.
how.Loose core screw
According to statistics, to occupy the main global technical position the transformer industry depends on two key data,RemchiTransformer in distribution room, commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage, China has been a powerful country in the production, manufacturing and application of dry-type transformers all over the world, but it is not a big country.
Under 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, so as to ensure the reliable and stable operation of machinery and equipment.
Remchi.Before and after sampling clean the periphery of the sampling port with clean or hairless linen.
The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by 20%.
Careless maintenance and insulation damage
