In fact, 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,KurjaliPower transformer insulation, 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 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.Kurjali,Transformer inspection nose sniffing methodNoise solution of dry-type transformerBeruniy,The dry-type transformer is composed of two winding resistances, resulting in four wiring groups: & ldquo; y, Y & rdquo;, & ldquo; D, Y & rdquo;, & ldquo; y, D & rdquo; and & ldquo; D, D & rdquo;. In China, only & ldquo; y, Y & rdquo; and & ldquo; y, D & rdquo; are selected. Because there are also two types of Y-connection with neutral line and without neutral line. If there is no neutral line, it will not be upgraded. All marks show that with neutral line, it will not be upgraded The letter N after the English letter Y indicates that the neutral line has transformer grounding wire. Yn wiring group, when UAB and UAB overlap, the minute hand points to . & ldquo; & rdquo; in the new wiring group, it is indicated by & ldquo; & rdquo.In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuitWhen the manufacturer of the power transformer samples from the automobile oil tank, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb,

Dry type transformer companyAccording to statistics, to occupy the main global technical position the transformer industry depends on two key data,KurjaliTransformer variable frequency power supply, China has been a powerful country in the production commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage, manufacturing and application of dry-type transformers all over the world, but it is not a big country.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.Range,Noise pollution control and prevention measures of dry-type transformerDue to poor sealing, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.Wiring mode of dry-type transformer:

Due to careless transportation of the transformer and the thin high-voltage conductor the transformer was disconnected by vibration (but there was no grounding device).Trustworthy,After hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal,KurjaliModel of three-phase oil immersed transformer, and the transformer will turn to all normal operation.The top and middle of the transformer oil tank, the flange plate, barrel skin and the middle of the waterproof sleeve at the upper end of the automobile oil tank. The internal iron core and winding clamp are hot due to partial magnetic leakage, resulting in insulation damage.In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?Kurjali,Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, 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.Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below .%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.
