Santa Susanna Santa Maria Jesuit ChurchLatest model of oil immersed transformer, D11 & rdquo;
& ldquo; YN, 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).
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?
Santa Maria Jesuit Church.In fact, apart from the application of the Finance Bureau, the industry has been trying to formulate and upgrade transformer commodities according to the specifications, so as to promote the improvement of energy consumption level of transformer commodities.
What is the wavelength of oil immersed transformer?
.Solenoid insulation deterioration
Power transformer manufacturer
Seal oil leakage
The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, and overload is not allowed in the whole process of operation.
Method and process of taking oil sample of power transformer
When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate),Santa Maria Jesuit ChurchNo load loss of dry-type transformer,Santa Maria Jesuit ChurchProtection of oil immersed transformer, 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.
Promise and keep promise.Analysis of common faults of oil immersed transformer:
According to statistics, to occupy the main global technical position, the transformer industry depends on two key data, 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.
The noise of dry-type transformer comes from
Santa Maria Jesuit Church.The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.
How to reduce the failure of dry-type transformer?
The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the 45 degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.
