The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct，BalahaniWhich is better for dry-type transformer， which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment， the output capacity can be increased by %.
Before application，BalahaniPower transformer parameters， the sampling container shall be cleaned with vehicle gasoline， soapy water or other organic solvents (such as trisodium phosphate) except oil stains and then washed with tap water until it is not alkaline， and the water can be evenly distributed from the bottle， and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a ℃ drying oven. After refrigeration， the bottle cap shall be tightly closed and cannot be opened before application.
BalahaniOil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.

Naturally， if the oil immersed transformer catches fire， please don"t panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire， please be rational to make the oil immersed transformer safer and more efficient.
Oil leakage of bolt or pipe external thread
Automatic system of centrifugal fan: measure the temperature data signal according to the PT thermistor temperature measuring resistor of the embedded parts at the hot part of the bottom pressure winding. The transformer load expands and the operating temperature increases. When the winding temperature reaches ℃， the system software automatically starts the centrifugal fan for refrigeration; When the winding temperature is as low as ℃， the system software will automatically terminate the centrifugal fan.
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.
Latest quotationThe 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，BalahaniHow much is the 2000 box transformer， 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.
On load commissioning:
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.
For the leakage that has already occurred， find the leakage point first， which can not be ignored. For the position with serious leakage， shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage， the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation， the goal of long-term treatment of leakage can be achieved.

In the case of dry-type transformer operation， there is more noise， and some even cause noise， which seriously endangers everyone"s no problem rest time and work. At this time， the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer"s network editor to simply understand it.
BalahaniThe iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core， which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating， which is resistant to corrosion and rust， with good strength and stiffness， which is conducive to adjusting the data and has a unique and neat style.
The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of -A / Min.
