For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation,TrevnerRecovery price of oil transformer, it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.Oil immersed transformerTrevner,How to make up oil for oil immersed transformer?When the full load test is carried out and everything is normal, the load can be connected.Verona,Due to careless transportation of the transformer and the thin high-voltage conductor, the transformer was disconnected by vibration (but there was no grounding device).Oil leakage of bolt or pipe external threadWhen 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,TrevnerDry type transformer scb13-1250kva, and loosen your thumb to make the oil enter the pipe,

Brief introduction of zero line of power transformerPrinciple 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,TrevnerAdvantages of oil immersed transformer, the communication AC magnetic flux will be caused in the transformer core (or magnetic core), 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 the problem of dryness shall be solved. Generally, 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.Which one is better,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?Fault judgment of power transformerThen clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice and then draw the oil sample.

What is the wiring mode of dry-type transformer?Fair price,Oil leakage at looper flangeTransformer manufacturers said that at this stage, China's energy-saving distribution transformer market is relatively scattered, coupled with the constraints of factors such as low threshold in the field, lack of evaluation and specifications, and inadequate technical innovation, resulting in slow marketing of energy-saving transformers.The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.Trevner,Seal oil leakageAccording to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.According to the condition of cracks
