Krasnoyarsk220Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut), wipe the Fushi blue film remover on the surface, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.

Verangala.It should be said that after the development trend of these years, the overall level of China's transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.
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.
.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?
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.

When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:
With Vietnam and Malaysia China's first UHV transmission experimental demonstration project, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.
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.
system.After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
Sound in case of phase failure
Analysis of common faults of oil immersed transformer:
There are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.
superior quality.The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the transformer.
The dry-type transformer used for power plant voltage transformation is different from the oil transformer. It is strictly prohibited to lead the way at the bottom voltage side to prevent the insulation layer of the dry-type transformer from penetrating due to overvoltage caused by overvoltage at the power grid side or lightning stroke on the line.
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,VerangalaThree phase transformer 380V to 208v, 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.
Verangala.If the volume of power transformer is too small the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore, which is not suitable for too large or too small.
Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin,VerangalaPrice of dry-type transformer shell, 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.
