When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,Los AngelesProduction process of oil immersed transformer,The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of .kg or kg. - bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source, sampling date, sampling person, weather conditions and other materials of the oil sample.Los Angeles, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period, you must pay attention to the following points. Whether there is abnormal sound,Los AngelesBox buried transformer, noise and vibration, whether there is abnormal smell such as coke smell, and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, we should also pay attention to the following aspects.The main reason is that the welding quality of electric welding is poor, there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.Kafr Takharim,For kVA power engineering transformer, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.The noise of dry-type transformer comes fromAvoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.

The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below kVA and the working voltage is below KV, which also ensures the rated voltage of kV; Oil immersed transformers are generally suitable for distribution equipment.When the output power P of the transformer is equivalent to the input power P, the efficiency & ETA; Equivalent, the transformer will not cause loss. But in fact, there is no such transformer. The electromagnetic energy of transformer always causes loss. The key of this kind of loss is copper loss and iron loss. Copper loss refers to the loss caused by the number of turns of transformer coil. When the current has a fever according to the number of turns of the coil, part of the electromagnetic energy changes into energy and is lost. Because the electromagnetic coil is generally wound by copper core wire with insulating layer,Los AngelesDry type transformer procurement, it is called copper loss.Oil leakage of bolt or pipe external threadDirect materialThe noise of dry-type transformer comes fromBrief introduction of zero line of power transformerThe raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.

The switching power supply lacks one phase of power;index,When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about kg of waste liquid stored at the bottom to clean the oil inlet, and then take the oil sample.In fact, the industry has been trying to formulate and upgrade transformer commodities according to the specifications, so as to promote the improvement of energy consumption level of transformer commodities.Power transformers are also used for testing which are called test power transformers. They can be divided into inflatable, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.Los Angeles,The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, that is, the disconnection component of the electric field is small.When using the oil sample of the power transformer in operation, and then take the oil sample.Power transformer manufacturer
