PoitiersDry type transformer box type transformerWhat are the precautions for seasonal use

The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, resulting in heat temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.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.Poitiers,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.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 and long-term scalding of iron core will lead to insulation aging.Rawah, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.What is the reason for the shutdown of power transformer?

In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuitOvertemperature alarm and trip: collect winding or iron core temperature data signals according to the temperature measurement resistor of PTC discrete system thermistor embedded in the bottom voltage winding. When the transformer winding temperature rises again, if it reaches ℃, the system software outputs the overtemperature alarm system; If the temperature rises to ℃ again and the transformer can no longer operate, and the transformer shall be tripped quickly.Careless maintenance and insulation damageProcess inspection,Manufacturing process and steps of dry-type transformerWhat is the wiring mode of dry-type transformer?The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.

Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling,PoitiersHow much is a 160 box transformer,PoitiersTemperature standard for oil immersed transformers, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.Quality department,The 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.Transformer isIt will also produce many faults,PoitiersHow many degrees do dry-type transformers trip, 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.Poitiers,Oil immersed transformer operationFalling foreign matters and piercingOil leakage of cast iron parts
