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 welding leakage test and NDT technology, surface treatment process and quality standards, Production process and quality standard of aluminum shield; Body suit iron insertion process, 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.

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,

Mbala.The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions,MbalaWhat are the components of an oil immersed transformer, generally from half a year to once a year;

How to reduce the failure of dry-type transformer?

.Oil leakage of bolt or pipe external thread

For no-load impulse closing of transformer, the output capacity can be increased by 20%.

The flange surface is uneven which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the tightening bolts are loose, and the installation and processing process is wrong,Mbala400 KVA price of box type transformer, so that the bolts are not tightened well, resulting in oil leakage.

Step up process of dry-type transformer?

Oil immersed transformer operation

Installation materials.When the whole process of winding wave of oil immersed transformer is calculated by using the marking method, the winding of oil immersed transformer is generally divided into multiple modules, and each module is replaced by an equivalent circuit, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module, and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.

Solenoid insulation deterioration

Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.

Word of mouth recommendation.When leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.

The proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text, we have already mastered the structure and characteristics of dry-type transformer. In this part, we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.

If the above provisions are not met,MbalaS13-50 / 10 power transformer, the problem of dryness shall be solved. Generally, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found, it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular, pay attention to cleaning the insulators of the power transformer and the top and bottom ends of winding resistance installation. Portable centrifugal fan or dry air compression or N2 shall be used to clean the dust in indoor space that is not easy to reach, such as ventilation duct, and there shall be no dirt.

Mbala.The method and whole process of taking oil sample of power transformer are as follows:

The sampling container is a colorless glass bottle with a wide mouth ground glass plug with a volume of 0.5kg or 1kg. 2-3 bottles shall be collected at a time for analysis and experiment. Labels shall be attached during sampling. Pay attention to the name, source sampling date, sampling person, weather conditions and other materials of the oil sample.

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.
