Shbin kanatilMaintenance items of oil immersed transformerNeed to be ready for emergencies

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.

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.

Shbin kanatil.The grounding resistance of, high voltage and bottom voltage shall not be less than 70% (10m & omega;) of the original value. The difference between the three-phase mean value of winding resistance measurement at the same temperature shall not exceed 2%,Shbin kanatilDry type transformer insulation material, which shall not exceed 2% compared with the last accurate measurement result.

Deterioration damage of transformer core insulation

.The flange surface is uneven, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.

It includes the performance and main uses of insulating layer materials various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core, cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.

The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:

When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?

Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.

Operation and maintenance management of oil immersed transformer

Recommendation and consultation.The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.

Operation of oil immersed transformer

When oil samples are used, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore,Shbin kanatil500 kV dry type transformer, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.

assets.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.

How to make up oil for oil immersed 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.

Shbin kanatil.The noise of dry-type transformer comes from

Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin,Shbin kanatilPrice of oil immersed transformer, 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.
