SilversonThreeIn order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.
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.
Abankai.The dry-type transformer used for power plant voltage transformation is different from the oil transformer. It is strictly prohibited to lead the way at the bottom voltage side to prevent the insulation layer of the dry-type transformer from penetrating due to overvoltage caused by overvoltage at the power grid side or lightning stroke on the line.
Method and process of taking oil sample of power transformer
.Oil leakage at electric welding position
When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover,AbankaiHow much is 250kVA transformer box type, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,
Oil leakage of cast iron parts
After 24 hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal,AbankaiPrice of dry-type transformer shell, and the transformer will turn to all normal operation.
The insulation of the through core anchor bolt clamping the iron core is damaged, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time,AbankaiReactance transformer, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.
(IV) the transformer on the column shall be stable and firm, and the waist rail shall be & phi; 0mm galvanized wire shall be wound over 4 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 0.2m.
The switching power supply lacks one phase of power;
The method and whole process of taking oil sample of power transformer are as follows:
Which one is better.Before application the sampling container shall be cleaned with vehicle gasoline, and then washed with tap water until it is not alkaline soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a 105 ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.
This is the example of power consumption engineering as power saving. The key reason is that the habitual calculation method ignores the copper loss.
The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is resistant to corrosion and rust, and has sound insulation and noise reduction.
Abankai.Oil leakage at electric welding position
From the appearance, 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;
Before no-load impulse closing, the transformer shall be placed for 24h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
