Les Abymes Primary energy efficiency model of dry-type transformer,

The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ Ω, The resistor is generally more than & omega;, According to Ohm's law, when the insulating layer is damaged, the current is only / of the total current flow, so as to play a guarantee effect. The higher the voltage, 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.What about oil immersed transformer fire?Les Abymes ,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.After no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.Kongens Lyngby,Noise dispersion of dry-type transformerOil leakage of cast iron partsThe technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ Ω, The resistor is generally more than & omega;,Les Abymes Price of box transformer 1600, According to Ohm's law, when the insulating layer is damaged, the current is only / of the total current flow, so as to play a guarantee effect. The higher the voltage, 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.

The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.Dry type transformer is a common electrical equipment, which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries, such as variable frequency power supply.The hanging core of dry-type transformer is a vital partQuality improvement,Fault judgment of power transformerInsulation 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.The switching power supply lacks one phase of power;

Oil immersed transformer companyinstall,Connection group structure of dry-type transformerHow to make up oil for oil immersed transformer?The noise of dry-type transformer belongs to low-frequency noise. In a small area most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, which is then scattered to the ears of consumers. Although the amount of noise is not very large and then causes gas vibration noise, the dispersion spacing and adverse effects are very large.Les Abymes ,The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.The main reason is that the welding quality of electric welding is poor, there are empty welding, needle holes,Les Abymes Recovery of electric cabinet transformer, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.In the electric field of the winding to the yoke, there must be a strong line breaking component, 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.
