There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let's master and consult in detail with the small editor of the dry-type transformer manufacturer.

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 insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, 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 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?

For oil transformer oil replenishment, unused transformer oil conforming to the new standard should be selected first. In addition, the oil with the same basic, same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than 5%, there is generally no problem. However, if there is more new remaining oil, oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain,Zovti vodkaLoss table of distribution transformer, and the acid value and dielectric loss shall not exceed the oil in the machinery and equipment.

The input and output three-phase power lines shall be connected to phase a, phase B and phase C respectively according to the color of yellow, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.

index.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.

Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.

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.

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

Quotation sheet.Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, resulting in overheating and melting of the iron core;

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:

Zovti vodka.The tap changer of power transformer shall also have strong insulation. 10kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.

Operation of oil immersed transformer

Due to poor sealing, generally the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.
