PatanOld box t(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; 0mm galvanized wire shall be wound over 4 turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than 0.2m.
Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation, which dissolve and ignite, resulting in a lot of steam bodies, greatly increasing the internal working pressure of the power transformer, causing the ignition of the casing, causing large-scale power failure,Brazzaville1600KVA box transformer price, endangering all normal production, manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.
Brazzaville.Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy, but consuming electromagnetic energy.
The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, 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.
.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 bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.
Difference between dry-type transformer and oil immersed transformer:
Operation of oil immersed transformer
The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than 150kV, class H dry-type transformers shall be used. If the standard impulse level of power load exceeds 150kV, epoxy resin adhesive shall be used to pour dry-type transformers.
A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?
how much.The noise of dry-type transformer comes from
In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word,BrazzavilleMaintenance specification for box type transformer, if there is any problem at a certain point, it will affect the whole power circuit

When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large it will not only increase the initial project investment, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.
Installation requirements.Careless maintenance and insulation damage
The transformer manufacturer will introduce the efficiency of the transformer to you
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.
Brazzaville.Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations,BrazzavilleType of dry-type transformer, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.
The noise of dry-type transformer belongs to low-frequency noise. In a small area, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.
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.
