Jotok.At rated power, the ratio of output power to input power of transformer is called the efficiency of transformer,JotokOil immersed transformer,JotokReactance transformer, i.e. & ETA; Is the efficiency of the transformer; P1 is the input power and P2 is the output power.
Dry type transformer
.In fact, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.

Manufacturing process and steps of dry-type transformer
The insulation between silicon steel sheets is damaged, resulting in overheating and melting of the iron core;
It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.

Difference between dry-type transformer and oil immersed transformer:
Brief introduction of zero line of power transformer
When the full load test is carried out and everything is normal, the load can be connected.
Where is it.The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.

Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below 0.2%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.
& 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).
