Power transformer plant

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,EchukaHigh overload capacity distribution transformer, the output capacity can be increased by 20%.

Echuka.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.

With the rapid development of society and the continuous development trend of computers, the calculation of data in the whole process of oil immersed transformer wave has long had results. Only effective selection of calculation entity models and methods is needed the accuracy of calculation conclusions can meet the needs of architectural design, and scientific and reasonable data method is selected, Not only can the current distribution of the oil immersed transformer be clearly defined in the development stage, but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope, which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.

.A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?

After 24 hours of continuous trial operation with a certain load the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.

(I) the distance between the external contour of 10kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than 1m; At the angle with actual operation, a spacing of more than 2m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.

When sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels, there are few manufacturers of dry-type transformer that can reasonably guarantee the instantaneous step-up in China. The step-up dry-type transformer has strong step-up capacity and good practical effect. The difference depends on that the transformer power switch without excitation regulator does not have the ability to change gear with load. Because this kind of tap power switch can cut off the whole process in a short time during the whole process of gear change samples shall be taken according to 2% of the total number of barrels (bottles).

The step-up dry-type transformer refers to the instantaneous operation of voltage. At this stage, cutting off the load current will cause arc burning between circuit breakers, tap power on and off or short circuit fault, it is generally used as a dry-type transformer that is not very strict in voltage regulation and does not need to be adjusted frequently.

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 sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to 2% of the total number of barrels (bottles).

& ldquo; YN, D11 & rdquo;, in which 11 indicates that when the working voltage phasor of the primary side line, as the minute hand, refers to the position at 12 o'clock, the phase voltage phasor of the secondary side is at 11 o'clock. That is, the phase voltage UAB of the secondary side lags 30 degrees behind the working voltage uab330 of the primary side line (or 30 degrees ahead).

Quality management.When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.

That is, the phase voltage UAB of the secondary side lags 30 degrees behind the working voltage uab330 of the primary side line (or 30 degrees ahead).

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.
