UlmierInrush cThe conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, we have already mastered the structure and characteristics of dry-type transformer. In this part we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.
Power transformer manufacturer
.The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core,ChittagongTransformer power transmission, 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.
Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, wind and sand.
The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.
Fault judgment of power transformer
The domestic transformer market is slow
Careless maintenance and insulation damage
Bidding.The hanging core of dry-type transformer is a vital part
Oil leakage at electric welding position
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, safety factor grounding device can be divided into grounding protection, 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.
When the whole process of winding wave of oil immersed transformer is calculated by using the marking method, the winding of oil immersed transformer is generally divided into multiple modules,ChittagongEnergy saving distribution transformer,ChittagongMain transformer of power plant, and each module is replaced by an equivalent circuit, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module, and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.
Honest management.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, resulting in oil leakage.
Step up process of dry-type transformer?
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?
Chittagong.Power transformer
Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.
The project cost is different. Compared with the purchase price of capacity transformer the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
