Akiichi ODAOil immersed air-cooled transformerRising market is coming

The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.

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, so as to reduce the electric field component intersecting with the insulating parts.

Akiichi ODA.The efficiency of transformer is closely related to the output power level of transformer. Generally, the greater the output power, the smaller the loss to output power ratio and the higher the efficiency. On the contrary, the smaller the output power, the lower the efficiency.

Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut), wipe the Fushi blue film remover on the surface, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.

.When the transformer is out of phase, if the second phase is blocked, 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:

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?

Operation and maintenance management of oil immersed transformer

High voltage fuse of transformer breaks one phase;

Transformer

The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?

Discount.The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.

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.

When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, parts experts can inspect special tools, insulation, etc. and deliver them after they are determined to be complete and reliable.

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.

Inspection standard.Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, appropriate surface treatment shall be carried out,Akiichi ODAStructural diagram of dry-type transformer, and then Fushi blue raw materials shall be selected for sealing treatment.

At rated power, i.e. & ETA; Is the efficiency of the transformer; P1 is the input power and P2 is the output power.

The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings,Akiichi ODAAllowable temperature and temperature rise of oil immersed transformer, 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, 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.

Akiichi ODA.If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.

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.

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,Akiichi ODAHow much is a 200 KVA box transformer, it is very easy to cause fire accidents, power failure, damage to machinery and equipment etc.
