Knowledge Introduction of Air-cooled Transformer

The Air-cooled Transformer not only reduces the loss of rotating equipment, reduces the cost of overhaul and maintenance, but also avoids shutdown accidents caused by long-term operation. Therefore, Air-cooled Transformer users have responded well. Next, let's take a look at Air-cooled Transformer's operation, maintenance, performance, and operation regulations. Here are some answers.

How does Air-cooled Transformer perform operation and maintenance?

Air-cooled Transformer should conduct detailed inspections regularly during normal operation so that potential accidents can be discovered in advance, and the changing trend of equipment operating conditions can be found. It is an important means to ensure the safe operation of equipment. Air-cooled Transformer should be mainly carried out as follows project inspection.

First, the Air-cooled Transformer has complete fire protection equipment. Second, there is no overheating of the lead connectors, bus bars, and cables. Third, the outside of the casing should be clean, without traces of discharge, cracks, and other abnormal phenomena. Fourth, the sound of the Air-cooled Transformer in operation should be normal, and there should be no noise or discharge sound inside. Fifth, the shell grounding wire is intact. Sixth, the Air-cooled Transformer temperature indicator is normal, and the temperature rise is within the specified range. Seventh, the radiator, and respirator are operating normally, the silica gel is dry, without discoloration, and the pressure release valve is normal. Eighth, the running fan is operating normally, and the pipeline valve is opened and closed correctly. Ninth, there is no overheating of the components in the cooler control box, and the control selector switch meets the requirements of the operation mode.

Performance and operating procedures of Air-cooled Transformer.

Air-cooled Transformer is non-flammable resin, does not support combustion during use, is flame-retardant, does not explode and releases toxic gases, does not cause harm to the environment, other equipment, and the human body, and is not sensitive to humidity, dust, and pollution; No partial discharge and no possibility of cracking. In addition, the high and low voltage coils are made of insulating materials, and are immersed in the H-grade solvent-free dipping varnish through the VPI vacuum pressurizing equipment many times, and are baked and cured at high-temperature many times. The product is Class H (180°C), and the main insulating material is Class C (220°C), with strong overload capacity and good short-circuit resistance. In the case of good ventilation, 20% overload operation is allowed.

The two AC power sources of the Air-cooled Transformer cooler are mutually backup to ensure a reliable power supply for the cooler. Before the transformer is put into operation, the cooling system is put into operation. Air-cooled Transformer coolers generally have four sets, each set of coolers is equipped with 1 submersible pump and 3 fans. The power supply adopts 380V three-phase power frequency AC power. The local control power supply is 220V power frequency AC power. 2 groups are used for operation, 1 group is for auxiliary operation, and 1 is for standby operation.
