Sean fugosBox type transformer cabinetWhat is it

If the volume of power transformer is too small, the transformer will be overloaded for a long time and it is easy to destroy machinery and equipment. Therefore,Sean fugosComplete list of Transformer Models, the rated capacity of the transformer should be selected according to the power consumption, which is not suitable for too large or too small.The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:Sean fugos,How to maintain dry-type transformer?When oil samples are used,Sean fugosReactor and transformer, the safety and fire safety technical specifications on the spot shall be strictly implemented.Trelliu,Dry type transformerThe plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.The insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, the disconnection component of the electric field is small.

From the appearance that is most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;The equipment can eliminate the shortcomings found in the patrol inspection, clean the porcelain waterproof casing casing, remove and replace the cracked or brittle leather pad, check and tighten the node, replenish the oil with less oil, check and replace the silica gel of the breathing mask, etc.Falling foreign matters and piercingtechnical service,Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core,Sean fugosRecycling of old box transformer, and long-term scalding of iron core will lead to insulation aging.The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the fixed finger is at o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.Recommendation and consultation,In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?How to make up oil for oil immersed transformer?The voltage regulating tap changer is not in place or poorSean fugos,The key reason for oil leakage is that there are defects in cast iron partsIt will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
