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, 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 20%.
On load commissioning:
Sagan.During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.
For the installation of lightning rod,SaganDry type transformer temperature, it is very easy to cause fire accidents, power failure, damage to machinery and equipment etc.
.The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?
Oil leakage at looper flange
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, the output capacity can be increased by 20%.
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 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.
resources.Power transformers are used in all walks of life
Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, 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.
Wiring mode of dry-type transformer:
When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate),SaganConstruction power transformer, it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom,SaganTransformer series, or it can be replaced by changing the oil.
Total quality assurance.Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.
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;
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.
Sagan.The key reason for oil leakage is that there are defects in cast iron parts
The switching power supply lacks one phase of power;
What is the reason for the shutdown of power transformer?
