Manafgat200 KVA dry type transformerWhy is it so versatile

When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?

Dry type transformer factory

Manafgat.If the input of dry-type transformer is an alternating switching power supply, its output voltage is directly proportional to the coil turn ratio of the output input solenoid coil. If a rechargeable battery is used, because it is DC, add a circuit in the input power supply circuit to change it into a continuously changing voltage. In that way the alternating DC current can be obtained at the output end.

The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well,ManafgatTransformer power transmission, resulting in oil leakage.

.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%.

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 main reason is that the welding quality of electric welding is poor, there are empty welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.

When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.

In order to better avoid overvoltage damage a group of overvoltage maintenance high-voltage Arresters (such as y4cs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.

From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;

Pursuit of excellence.In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

Dry type transformer manufacturer

Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, 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,ManafgatOil immersed transformer foundation, 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.

The switching power supply lacks one phase of power;

quality index.Dry type transformer

The insulation of the through core anchor bolt clamping the iron core is damaged, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.

The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side),ManafgatPrice of 125kva dry type transformer, and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.

Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.
