Grand caradusaDifference between power transformer and dry-type transformer,

Some are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation,Grand caradusaYuxi transformer, and there is still oil leakage without sealing effect.

The switching power supply lacks one phase of power;

Grand caradusa.The transformer manufacturer will introduce the efficiency of the transformer to you

In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.

.Power transformer

Oil leakage of bolt or pipe external thread

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,Grand caradusaPower transformer price: 1000KVA, and has sound insulation and noise reduction.

Oil immersed transformer operation

Protection mode for type selection of dry-type test transformer

The method and whole process of taking oil sample of power transformer are as follows:

install.The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.

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.

Oil immersed transformer company

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.

Inspection basis.Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.

The domestic transformer market is slow

The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.

Grand caradusa.Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.

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, 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.

Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.
