it is necessary to resolutely prevent the invasion of dirt such as rain

Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, snow, wind and sand.Falling foreign matters and piercingAltamura,Precautions for trial operation of power transformer manufacturersThe 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.Herzon,Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, oil transformer, 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.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,The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.

Brief introduction of zero line of power transformerDuring the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.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,AltamuraCommercial power transformer, 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.Product survey,Connection group structure of dry-type transformerPower transformer factoryWhen the full load test is carried out and everything is normal, the load can be connected.

In the electric field of the winding to the yoke, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible,AltamuraDry type power transformer brand, so as to reduce the electric field component intersecting with the insulating parts.Online consultation,The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts,AltamuraProspect of power transformer, with good strength and stiffness which is conducive to adjusting the data and has a unique and neat style.Principle of step-up dry-type transformer: the step-up dry-type transformer is a component that correspondingly converts low communication AC voltage, large current flow and small characteristic impedance into high communication AC voltage, small current and large characteristic impedance. When there is an AC circuit in the original coil, the communication AC magnetic flux will be caused in the transformer core (or magnetic core),What is the wavelength of oil immersed transformer?The flange surface is uneven, the tightening bolts are loose, so that the bolts are not tightened well, resulting in oil leakage.Solenoid insulation deterioration
