Abstract

The invention discloses an oil immersed discharge coil which comprises a high-voltage rolling crimp ferrule, a low-voltage rolling crimp ferrule, an oil tank, an ascending seat and a flange, wherein the materials of the ascending seat and the flange are the same as that of the oil tank; the oil tank is provided with an expansion box, whose air vent uses the same material with that of the oil tank; and the connection parts of the components with the same material of the oil immersed discharge coil are connected in a fusion welding manner. With the adoption of the oil immersed discharge coil disclosed by the embodiment of the invention, as the components of the oil immersed discharge coil are connected by adopting a seamless fusion welding process, the oil immersed discharge coil is fully sealed, and the problem of oil leakage of the oil immersed discharge coil is solved; and meanwhile, the oil immersed discharge coil is free from maintenance due to no leakage, so that a large amount of maintenance cost can be saved.

Description

technical field [0001] The invention relates to the field of electric power systems, and more specifically relates to an oil-immersed discharge coil. Background technique [0002] The discharge coil is used in parallel connection with the high-voltage shunt capacitor bank in the power system, so that the residual charge after the capacitor bank is removed from the power system can be quickly discharged. In order to make the residual voltage drop to the specified value within the specified time, to ensure the safety of the equipment and the safety of the maintenance personnel when the switch is closed again. [0003] At present, there are many structures and types of discharge coils used in power systems, such as: oil-immersed type, semi-enclosed casting type, fully-enclosed casting type, etc. Due to structural and technical reasons, the above products all have shortcomings, such as pouring products, which are easy to crack and have poor anti-fouling ability, and oil-immerse...
