Oil leakage at looper flangeThe zero line is mainly used in the working circuit. The voltage caused by the zero line is equivalent to the line resistance multiplied by the current of the working circuit. Because of the distance, the voltage caused by the zero line can not be ignored. As a countermeasure to maintain life safety, but only as a maintenance line. Use the affirmation of the earth & ldquo; ” Voltage. When the machine and equipment casing is electrified, the current will be quickly grounded. Even if there is a lead for the PE line, it will be grounded from the surrounding grounding body.Estoli,It is understood that in China, transformers have experienced the whole process of replacing many series products such as sss. As early as the middle and late s, S Series lossless distribution transformers were selected in China to replace the high energy consumption transformers of jb- and jb - Specifications operating in the power network at that time. Since the th century, urban power grids have been transformed all over the country, and S series distribution transformers have been used to replace S Series. In recent years, S and S commodities are gradually selected in large quantities in the transformation of urban and rural power networks in China, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.Chilibre,Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings commerce, airports, tunnel construction, chemical enterprises and factories.Dry type transformer manufacturerThe voltage regulating tap changer is not in place or poor

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 secondary inductive equipment of the distribution station (such as transformer, voltage transformer, automobile relay, AC, etc.) operates normally. According to the AC current, the winding transformer core will send out a symmetrical rhythm and a certain tone & ldquo; Buzz, there will be noise and even & ldquo; Crackle & rdquo; The charging and discharging sound can distinguish the generation and characteristics of common equipment faults according to the music law and sound transformation when everything is normal and abnormal.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,EstoliOperation and maintenance of dry type transformer, and then causes gas vibration noise,Estoli10kV dry type transformer test,EstoliTransformer and box transformer, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.Create brilliance,The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?Oil leakage at electric welding positionPower transformers are used in all walks of life

The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.Direct labor,It includes the performance and main uses of insulating layer materials, various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.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, and then the iron loss is considered and the copper loss is ignored. In fact for a certain load, the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer, so it consumes electromagnetic energy.After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.Estoli,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.Power transformer plantWhat is the important role of power transformer
