Welcome to the official website of Jiangsu Hengyi Transformer Co., Ltd.!
The oil-immersed transformer has too low, making the rigid waterproof sleeve transport wire and the total switch naked to the air, and the insulation level will be greatly reduced, so it is easy to cause charging through the battery.
Oil-immersed transformers have a plurality of separate oil systems that are safely protected between each other. When the oil immersion transformer is running, the oil in such separate oil systems is in communication with each other. The situation in the finished oil and operation work is not the same. It is necessary to make gas chromatographs in oil to identify whether there is irreversible problem. .
(1) The main intradermal oil system. The oil system in which oil near the bypass is in the main body system, including FRP cooling tower or heat pipe, oil, 35kV and below oil, oilproof casing in oil, oilproof casing. Come on releases the gas deposits stored in this oil system through the end of the world. In general, the prefabricated components need to have their own air plugs. Important insulation and refrigeration effect in the main body. Oil also improves the tensile strength of the electrical equipment of the insulating paper or the insulating thick panel. When the mechanical pump is refueling, if some prefabricated components cannot take the same mechanical pump tensile strength as the main vehicle fuel tank, apply temporary brake safety, such as the shutoff valve with the cannula and the main oil box.
(2) The oil in the switching switch of the switch in the total switch of the power supply. This part of the oil has its own maintenance system, namely a circulating relay, storage cabinet, pressure relief valve. The oil in the total switch in the total switch of this power supply and the total flow effect of the elimination electrical flow. The oil will go in the oil caused by the conversion to turn off the total traffic of the load, this oil system is highly close to close, even if the alternatives are maintained in the transformation, the electrical pressure must also be maintained.
(3) Close up of 60kV and above rated current. Imported insulation in this oil system, or improves the electrical equipment of the oil-capacitor sensor rigid waterproof sleeve to tensile strength. When refueling within the body, the top terminal terminal of the rigid waterproof sleeve should be sealed, preventing the air inlet.
(4) Pressing the working group group outlook in the oil, or the tank working group group outlook in the oil box. Three-phase 500kV transformer's 髙 髙 Working Group panel wraway on the wavy insulation safety protection oil system. This oil system is an important insulation. For a simple structure, this oil system can also be designed into a separate oil system in accordance with the connection or plan of the inner oil system.
(5) When the oil immersion transformer is performed, the air is first placed, and the gas is released in accordance with the air plug releases a very likely stored gas. It can be predicted whether or not reversible common problems can be predicted according to the analysis of gas chromatographs in the oil of each system. Each oil system must operate, such as the change in oil capacity of digestion oil and the contraction, cutting valve, airfridge, glass steel cooling tower and heat pipe heat pipe, and the main oil tank. Each oil system has a good comparative characteristics, and the oily in which the total switching switch of the switching switch in the total switch. The main body oil can be released when the main body is released separately without releasing the oil.
