Connection group structure of dry-type transformer

Naturally, please don't panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.

Vanni.How is the quality level of dry-type transformer compared with foreign countries?

Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports,VanniHigh voltage bushing of oil immersed transformer, tunnel construction, chemical enterprises and factories.

.Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, and then reduce the building structure noise transmitted by dry-type transformer oscillation.

Oil immersed transformer company

Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window,VanniThree phase power transformer, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.

Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.

The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than 150kV, class H dry-type transformers shall be used. If the standard impulse level of power load exceeds 150kV, epoxy resin adhesive shall be used to pour dry-type transformers.

In 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.

Quality department.(I) the distance between the external contour of 10kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer, and the distance shall not be less than 1m; At the angle with actual operation, a spacing of more than 2m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.

Deterioration damage of transformer core insulation

The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?

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, weather conditions and other materials of the oil sample.

For more, please check.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,VanniPrice list of 315 KVA box type transformer, welding leakage test and NDT technology, surface treatment process and quality standards, copper, 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.

Transformer manufacturers said that at this stage, China's energy-saving distribution transformer market is relatively scattered, coupled with the constraints of factors such as low threshold in the field, uneven companies, lack of evaluation and specifications, and inadequate technical innovation, resulting in slow marketing of energy-saving transformers.

The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.

Vanni.When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?

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 oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.

After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.
