BaktapurScb13 For example, in the 1970s,RubioIs the dry-type transformer a box transformer, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ 4Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.
When sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to 2% of the total number of barrels (bottles).
Rubio.Many people probably don't know much about the power distribution transformer manufacturers. In fact, the transformer can be plugged in for trial operation after careful inspection before capital investment. During the trial operation period,RubioParameters of 250kVA oil immersed transformer,RubioOil immersed single phase transformer, you must pay attention to the following points. Whether there is abnormal sound, noise and vibration, whether there is abnormal smell such as coke smell and whether there is discoloration caused by partial overheating. Ventilation is good. In addition, we should also pay attention to the following aspects.
The noise of dry-type transformer comes from
.After 24 hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.
Noise dispersion of dry-type transformer
Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut), wipe the Fushi blue film remover on the surface, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.
Before application the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, 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.
With Vietnam and Malaysia, China's first UHV transmission experimental demonstration project, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world, occupying the main technical position of the industry development trend. In addition, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.
In specific daily life, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is, the greater the output power is. On the contrary, it is very small.
Online consultation.For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.
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, that is, the disconnection component of the electric field is small.
How to reduce the failure of dry-type transformer?
When the manufacturer of the power transformer samples from the automobile oil tank, after opening the sealing cover, 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,
Executive standard.Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited the generator set must be disassembled first.
Transformer inspection ear
In the whole process of transmitting electromagnetic energy in the power supply system, it will inevitably cause the loss of voltage and output power. When transporting the same output power, the voltage loss is inversely proportional to the voltage, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.
Rubio.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:
The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.
Performance and main parameters of common metal composites various welding processes and machinery and equipment, preparation treatment of thick steel plate, blanking process, production and manufacturing process and quality standards of automobile oil tank, riser, coupling and oil storage tank cabinet, surface treatment process and quality standards, copper, wire installation process, body dryness solution and dry transformer oil solution process, vacuum pump oil immersion, general installation process, leakage test and leakage detection process and quality standards. Performance parameters of key work clothes, machinery and equipment of each process flow; The natural working environment is basically regulated.
