KotleckNational standard for loss of oil immersed transformerHow does the market move when the spot price rises and the spot price falls

What is the wiring mode of dry-type transformer?The noise of dry-type transformer comes fromKotleck,In order to better avoid overvoltage damage, a group of overvoltage maintenance high-voltage Arresters (such as ycs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.Colegiales, 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, 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).What is the wavelength of oil immersed transformer?Naturally, if the oil immersed transformer catches fire, please don't panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.

Noise dispersion of dry-type transformerThe insulation of the through core anchor bolt clamping the iron core is damaged, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.Highly recommended,Kotleck1600KVA transformer price, porcelain,Kotleck480v dry type transformer, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.If the above provisions are not met,KotleckApplication of oil immersed transformer, the problem of dryness shall be solved. Generally it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N shall be used to clean the dust in indoor space that is not easy to reach, such as ventilation duct, and there shall be no dirt.

Power transformer manufacturerFocus on Development,The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?Two point grounding device of iron core caused by residual welding scar;Oil leakage at looper flangeKotleckPower transformer factoryDeterioration damage of transformer core insulationFor no-load impulse closing of transformer, pay attention to the following matters:
