When oil samples are used， the safety and fire safety technical specifications on the spot shall be strictly implemented.
Oil immersed transformer company
LucernekDry type transformer is a common electrical equipment， such as variable frequency power supply.
When sampling in bulk gasoline barrels， samples shall be selected according to % of the number of gasoline barrels， but not less than barrels. When sampling in batches of small and medium-sized pails or bottles， samples shall be taken according to % of the total number of barrels (bottles).

What is the wavelength of oil immersed transformer?
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.
The project cost is different. Compared with the purchase price of capacity transformer， the purchase price of dry-type transformer is much higher than that of oil immersed transformer.

If 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， 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).
When using the oil sample of the power transformer in operation， it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about kg of waste liquid stored at the bottom to clean the oil inlet，LucernekBidding information of power transformer， and then take the oil sample.

LucernekWhen we apply oil immersed transformer， we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?
(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m， and a guardrail of no less than m shall be installed around it， and a warning sign shall be hung at a prominent position.
For kVA power engineering transformer， plastic parts are selected in the middle of iron core clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.
