Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.Oil leakage at electric welding positionBrental,What is the cause of power transformer core failure?Power transformers are used in all walks of lifeNikopol,Before no-load impulse closing,BrentalTransformer inductor, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.The conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, and a guardrail of no less than m shall be installed around it and a warning sign shall be hung at a prominent position.

In the case of dry-type transformer operation, there is more noise, and some even cause noise, which seriously endangers everyone's no problem rest time and work. At this time, the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.The insulation between silicon steel sheets is damaged, resulting in overheating and melting of the iron core;The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ Ω, The resistor is generally more than & omega;,Brental220 kV Transformer, According to Ohm's law, when the insulating layer is damaged, the current is only / of the total current flow, so as to play a guarantee effect. The higher the voltage, the smaller the resistance, in other words, in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.Standard requirements,The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.After tightening the loose bolts, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin and solve the bolts that are likely to leak,BrentalDimensions of 1600KVA oil immersed transformer, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.

The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, the disconnection component of the electric field is small.Workshop cost,The noise of dry-type transformer comes fromThe transformer manufacturer will introduce the efficiency of the transformer to youThe flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.Brental,The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.How to reduce the failure of dry-type transformer?
