Power transformer manufacturerTurn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined,Saint Lucia Dry type or oil immersed transformer for box transformer, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.Saint Lucia ,How to maintain dry-type transformer?Causes of fire in power transformerAppeldoren,Manufacturing process and steps of dry-type transformerPlug 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, ignition, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.Overload or short circuit occurs inside the power transformer. Flammable insulating raw materials are endangered by high temperature and electric isolation, 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.

Sound in case of phase failureWhat is the cause of power transformer core failure?The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings,Saint Lucia Dry type transformer and oil immersed transformer, because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding, that is, the disconnection component of the electric field is small.Encyclopedic knowledge,Seal oil leakageIf the power transformer stops running for more than h (if the allowable time should be reduced when the ambient humidity is & amp; gt; %), it should be insulated before putting into use, and accurately measured with a V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ mfl the insulation resistance from the secondary side to the ground should be ^ mh, with good strength and stiffness and the insulation resistance from the iron core to the ground should be & amp; gt; mfl (note that the grounding device piece should be removed).The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, which is conducive to adjusting the data and has a unique and neat style.

Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition,Saint Lucia Parameters of oil immersed transformer, in the installation and use process of lightning rod, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, please connect all routes as far as possible to prevent other faults.Click to view,Oil leakage of heat pipe radiatorThe cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions, generally from half a year to once a year;What about oil immersed transformer fire?Saint Lucia ,The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.Operation and maintenance management of oil immersed transformerBrief introduction of zero line of power transformer
