Noise solution of dry-type transformerBefore and after sampling, clean the periphery of the sampling port with clean or hairless linen.Tupiza,The rate of transformer is: n = P / pxo%, that is, when the copper loss of transformer is equivalent to iron loss, the rate is very large. Therefore, the load of transformer is: = P / PK. Fully consider the active power loss caused by reactive power in the system software during transformer operation. The load adjustment is: it can be seen from the calculation of load formula that the large rate of transformer does not occur when the load is full, Generally, it is about %, but when selecting the transformer capacity, we should select effective transformers according to the load condition and load, so as to make the transformer in the situation of economic development and achieve the goal of power saving.(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m, and a guardrail of no less than m shall be installed around it, and a warning sign shall be hung at a prominent position.Kurdjali,For kVA power engineering transformer, plastic parts are selected in the middle of iron core, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, safety factor grounding device can be divided into grounding protection, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.The power transformer is composed of two or more electromagnetic coils wound around the same transformer core. The winding resistance is connected according to the alternating electromagnetic field and works according to the basic principle of magnetic effect of current. The installation position of power transformer shall be considered to be conducive to operation, maintenance and transportation, and a reliable area shall be selected at the same time. The rated capacity of the transformer must be effectively used when applying the 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;, 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 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.Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded,TupizaGrid transformer, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary the load can be reduced or the operation of the transformer can be stopped.management,TupizaStructure diagram of oil immersed transformer,TupizaOil immersed dry type transformer, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is, the greater the output power is. On the contrary, it is very small.The method and whole process of taking oil sample of power transformer are as follows:The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.

Solenoid insulation deteriorationTotal quality management,Common problems of tap changer of power transformerDry type transformer, is used to change the AC current (current) of a certain standard value into another or several types of working voltage (current) with the same frequency and different standard values. According to the supervision sampling inspection data of the third quarter of last year released by AQSIQ, among the kinds of dry-type transformer commodities manufactured by manufacturers in provinces and municipal districts across the country, kinds of commodities were found to be inconsistent with the provisions of relevant specifications, with a compliance rate of %& ldquo; This result mostly shows the quality level of China's dry-type transformer industry at the present stage.Difference between dry-type transformer and oil immersed transformer:Tupiza,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.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.The conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.
