Careless maintenance and insulation damagePower transformerSiuna ,Two point grounding device of iron core caused by residual welding scar;The 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.Aalst,Oil leakage at electric welding positionThe scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?Dry type transformer factory

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,Siuna How much is a 50 KVA box transformer, 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, the minute hand points to . & ldquo; & rdquo; in the new wiring group, it is indicated by & ldquo; & rdquo.The transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment, the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.Causes of fire in power transformerWork courses,The voltage regulating tap changer is not in place or poorThe clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.Noise solution of dry-type transformer

Oil leakage of heat pipe radiatorInstallation conditions, which dissolve and ignite, resulting in a lot of steam bodies, greatly increasing the internal working pressure of the power transformer, causing the ignition of the casing, causing large-scale power failure, endangering all normal production, manufacturing and activities. There are three reasons for fire accidents in the operation of power transformers.How is the quality level of dry-type transformer compared with foreign countries?Method and process of taking oil sample of power transformerSiuna ,Siuna Technology of oil immersed transformer,(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound,Siuna How much is a 250kVA box transformer, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.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.
