IndiaCharacteristics of oil immersed transformerWhat components are included in the order

The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.

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, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.

How to select dry-type transformer

The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?

Recommendation and consultation.What is the wiring mode of 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, and there is still oil leakage without sealing effect.

Power transformer manufacturer

The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the closing frequency shall be 5 times, the delay time after power receiving shall not be less than 10min, and the time interval of each closing shall not be less than 5min.

In order to promote the use of energy-saving transformers,IndiaPrice of dry type 800kVA transformer, the Ministry of finance, the Ministry of industry and information technology and the national development and Reform Commission jointly promulgated the detailed rules for the implementation of energy-saving distribution transformers of energy-saving products benefiting the people project as early as 2012, providing subsidies of 4-30 yuan / KVA for energy-saving transformers.

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.

India.The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ 4Ω, The resistor is generally more than 2000 & omega;, According to Ohm's law, when the insulating layer is damaged, the current is only 1 / 500 of the total current flow so as to play a guarantee effect. The higher the voltage, the smaller the resistance, in other words, in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.

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