ZalkentTransfoSound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
Sound causing short circuit obstruction. If not handled properly, 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?
.Common problems of tap changer of power transformer
Oil immersed transformer operation
The key reason for oil leakage is that there are defects in cast iron parts
Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
Transformer manufacturers generally adopt IP20 protective casing, which can avoid the entry of solid dirt with a diameter of more than 12mm, rats, snakes, cats, birds and other animals, resulting in vicious common faults such as short-circuit fault and power failure, and provide a safe natural barrier for the energized part. If the transformer equipment must be outdoors, IP23 protective casing can be adopted, which can avoid being equally divided with the above IP20 protective effects However, IP23 casing will reduce the refrigeration capacity of the transformer, so pay attention to the reduction of its operating volume.
The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ 4Ω,YubolanDry type or oil immersed transformer for box transformer, 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,YubolanPower transformer function, 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.
production.Power transformer factory
Before application, the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and the water can be evenly distributed from the bottle, the bottle cap shall be tightly closed and cannot be opened before application.
(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.
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,Yubolan10kV dry type transformer scb12, 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.
Where is good.Dry type transformer company
The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions, generally from half a year to once a year;
The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.
Yubolan.In specific daily life, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is, the greater the output power is. On the contrary, it is very small.
Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
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.
