When oil samples are used， the safety and fire safety technical specifications on the spot shall be strictly implemented.
Manufacturing process and steps of dry-type transformer
Bandorban CountyThe insulation of the through core anchor bolt clamping the iron core is damaged， resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;
The insulating layer in the middle of the silicon steel plate is aging， 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.
Vilikinov gorodThe 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，Bandorban CountyHow much is a 50 KVA box transformer， 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，Bandorban CountyOil immersed air-cooled transformer， 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.
With the rapid development of society and the continuous development trend of computers， the calculation of data in the whole process of oil immersed transformer wave has long had results. Only effective selection of calculation entity models and methods is needed， the accuracy of calculation conclusions can meet the needs of architectural design， and scientific and reasonable data method is selected， Not only can the current distribution of the oil immersed transformer be clearly defined in the development stage， but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope， it is necessary to resolutely prevent the invasion of dirt such as rain， snow， wind and sand.
When the operating oil is mixed with different types of new oil or used for oil， in addition to the accurate measurement of the cold filter point of the mixed oil it is also necessary to carry out high and low temperature test and sludge test， and observe the sludge accumulation. The accumulation cannot be accessed. The results of the operation of the mixing template are not that the original oil is very poor， so it can be managed and used in a mixed manner.
The hanging core of dry-type transformer is a vital part
Installation requirementsOil leakage of heat pipe radiator
After the oil is drained， all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack， and the lifting point shall be on the common earrings or bolts. If necessary， the human resources traction belt shall be used as a guide.
The time difference between different steps of three-phase power switch of switching power supply shall be less than ms， the closing shall be maintained by high-voltage arrester， and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).
Power transformer manufacturer
originalFault judgment of power transformer
The fundamental reason for this kind of inaccuracy is that when the transformer & ldquo; Dalar trolley & rdquo; is considered according to the size of capacity utilization rate， the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate， and then the iron loss is considered and the copper loss is ignored. In fact， the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer， so it consumes electromagnetic energy.
What about oil immersed transformer fire?
Bandorban CountyThe heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding， oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.
In 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?
The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore， it must also be changed to produce flexible connection.
