jeremy Quotation for oil immersed transformerThe industry accelerates the pace of adjustment

What about oil immersed transformer fire?Therefore, 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,jeremy Market price of scb11 dry type transformer, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, and the harm will not expand to a greater extent.jeremy ,Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.Power transformer manufacturerBeroroha,(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than m; At the angle with actual operation, a spacing of more than m shall be reserved; If metal fence is selected, and the load shall be gradually increased from % it can be transferred to on-load operation, % and % by grade.

The dry-type transformer is composed of two winding resistances, resulting in four wiring groups: & ldquo; y, Y & rdquo;, & ldquo; D, Y & rdquo;, & ldquo; y, D & rdquo; and & ldquo; D, D & rdquo;. In China, only & ldquo; y, Y & rdquo; and & ldquo; y, D & rdquo; are selected. Because there are also two types of Y-connection with neutral line and without neutral line. If there is no neutral line, it will not be upgraded. All marks show that with neutral line, it will not be upgraded The letter N after the English letter Y indicates that the neutral line has transformer grounding wire. Yn wiring group,jeremy 1000 kV Transformer, when UAB and UAB overlap, the minute hand points to . & ldquo; & rdquo; in the new wiring group, it is indicated by & ldquo; & rdquo.The visual inspection method is that the staff use human eyes to observe the appearance change of the visible parts of the operating equipment to find the abnormal conditions of the equipment, such as discoloration, deformation, offset, cracking, loosening, ignition smoke, oil leakage, broken strand disconnection, short-circuit fault marks hanging of dirty things, which can be inspected according to the visual inspection method. Therefore etching and turbidity, visual inspection is one of the common methods of equipment inspection.Causes of fire in power transformerresources,Sound in case of phase failureIt includes the performance and main uses of insulating layer materials, various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.The noise of dry-type transformer comes from

How to reduce the failure of dry-type transformer?Which one is better,Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.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.Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling,jeremy Grid transformer, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.jeremy ,Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; mm galvanized wire shall be wound over turns in an even number. The iron wire shall not have a connector and shall be tightened after winding. The distance between the waist rail and the energized part shall not be less than .m.Analysis of common faults of oil immersed transformer:
