The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in the ignition of power transformer. Therefore two-color short circuit or short circuit on the ground, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.

What is the wiring mode of dry-type transformer?

Naconde.Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy but consuming electromagnetic energy.

The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at 12 o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.

.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?

Before no-load impact closing, the pose period of overcurrent protection shall be set to zero,Naconde1000 kV Transformer, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.

The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of 0.5kg or 1kg. 2-3 bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source, sampling date, sampling person, weather conditions and other materials of the oil sample.

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?

According to statistics, to occupy the main global technical position, 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.

Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, and then reduce the building structure noise transmitted by dry-type transformer oscillation.

Professional is king.In specific daily life,NacondePower high voltage transformer, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?

The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.

The key reason for oil leakage is that there are defects in cast iron parts

Method and process of taking oil sample of power transformer

reform.& 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).

The transformer manufacturer said that the selection should be based on the application environment of the dry-type transformer. For the extremely extreme environment, the dry-type transformer should be poured with epoxy resin glue. Because this kind of environment does not need to heat the dry-type transformer, it can operate immediately. However, for the general application environment, the class H dry-type transformer can be used.

The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings 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.

Naconde.When the screw of the through core extruder holding the iron core of the transformer is loose, there are screw cap parts left on the iron core, or small metal materials fall into the transformer,NacondeMain transformer of power plant, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak, squeak & rdquo; It's like a magnet sucking a small washer, while the working voltage, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer, and can be solved until power failure.
