Power transformer factoryOil leakage of cast iron partsBrussels,It is understood that in China transformers have experienced the whole process of replacing many series products such as sss. As early as the middle and late s, S Series lossless distribution transformers were selected in China to replace the high energy consumption transformers of jb- and jb - Specifications operating in the power network at that time. Since the th century, urban power grids have been transformed all over the country, and S series distribution transformers have been used to replace S Series. In recent years, S and S commodities are gradually selected in large quantities in the transformation of urban and rural power networks in China, and their full load loss is % - % less than that of S transformer.Some are tied with plastic tape, and some immediately press the two edges together,BrusselsPrinciple of power transformer, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.Le Port,When using the oil sample of the power transformer in operation,BrusselsDirect transformer, 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, and the load shall be gradually increased from %, % and % by grade.

Operation of oil immersed transformerVisual inspection method for transformer inspectionFor 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.Sales Department,The main reason is that the welding quality of electric welding is poor, there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.Seal oil leakageFalling foreign matters and piercing

What about oil immersed transformer fire?Installation requirements,The 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,BrusselsWorking principle of power transformer, the fixed finger is at o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.The domestic transformer market is slowBrief introduction of zero line of power transformerBrussels,The hanging core of dry-type transformer is a vital partTherefore, in the operation prevention and regulation of relay protection dry-type transformer it is necessary to find the short-circuit fault point according to the fault situation, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.Careless maintenance and insulation damage
