Note: in the whole process of safety patrol inspection， the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself， terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal significantly expanded， the cause shall be found immediately and certain effective measures shall be taken. If necessary， the load can be reduced or the operation of the transformer can be stopped.

NagsvariPower transformer is indispensable for power stations and substations， but we must pay attention to many problems in the whole process of applying power transformer.
The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings， most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding，Nagsvari1250KW dry type transformer， that is， the disconnection component of the electric field is small.
KirkukIn specific daily life， we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
Therefore， in the operation prevention and regulation of relay protection dry-type transformer， it is necessary to find the short-circuit fault point according to the fault situation， lock the fault point， and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time， if all fields are clear， disconnect the switching power supply at the fault point， the maintenance work of employees will be carried out smoothly， and the harm will not expand to a greater extent.
In the whole process of transmitting electromagnetic energy in the power supply system， it will inevitably cause the loss of voltage and output power. When transporting the same output power， the voltage loss is inversely proportional to the voltage， and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.

Hand touch method for transformer inspection
Under normal conditions， the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation， the operation and maintenance management staff shall improve the safety inspection range of the transformer， and immediately communicate and contact with the on-site project staff in case of any problems， so as to ensure the reliable and stable operation of machinery and equipment.
marketNaturally， if the oil immersed transformer catches fire，NagsvariEuropean box type transformer， 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.
In terms of the place of use， dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire， and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;
After sampling， bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
In the electric field of the winding to the yoke， there must be a strong line breaking component， 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.
Industry managementPlug in the power with full load first， observe and detect that the input and output voltage meets the regulations. At the same time，NagsvariStructural diagram of dry-type transformer， check whether the equipment has abnormal sound， ignition， odor and other abnormal conditions. If there is any abnormality， please cut off the input switching power supply.
Overtemperature alarm and trip: collect winding or iron core temperature data signals according to the temperature measurement resistor of PTC discrete system thermistor embedded in the bottom voltage winding. When the transformer winding temperature rises again， if it reaches ℃， the system software outputs the overtemperature alarm system; If the temperature rises to ℃ again and the transformer can no longer operate， the overtemperature trip data signal must be transported to the secondary maintenance circuit and the transformer shall be tripped quickly.
Wiring mode of dry-type transformer:
NagsvariThe no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer， the delay time after power receiving shall not be less than min the closing frequency shall be times， and the time interval of each closing shall not be less than min.
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， it is very small.
