Embodiment Construction

[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with the examples.

[0022] like figure 1 , 2 As shown, an oil-immersed arc suppression coil includes an iron core 3, a coil 2, a cladding layer 4, and a separator 9; the coil 2 is wound on the outer wall of the iron core 3, and the cladding layer 4 is wrapped on the outer surface of the coil 3, The base 1 is fixed with a fixed seat 6 by a bolt 7, and the fixed seat 6 is fixedly connected with the lower end of the iron core 3 by a screw 8. The iron core 3 is evenly distributed with gaps 10 along the circumferential direction, and a partition 9 is inserted correspondingly in the gap 10, which can be The iron core 3 is provided with 3-12 gaps 10 along the circumferential direction.

[0023] The iron core 3 is made up of the following raw materials in parts by weight:

Abstract

The invention relates to an oil-immersed type arc suppression coil, which comprises an iron core, a coil, a cladding layer and clapboards. The coil winds the outer wall of the iron core; the cladding layer is cladded on the outer surface of the coil; a fixed seat is fixed on the base through bolts, and is fixedly connected with the lower end of the iron core through screws; gaps are uniformly distributed on the iron core along a circumferential direction; the clapboards are inserted in the gaps. The iron core of the arc suppression coil adopts the iron core with the gaps, so that magnetic saturation is avoided, compensating current and voltage form a linear relation, and the higher harmonic component is reduced; the demagnetizing coil does not support combustion during the use process, can be flame retardant, does not explode and release poisonous gas, cannot damage the environment, other equipment and a human body, and is insensitive to humidity, dust and pollution; the selected material cannot pollute the environment, and can be recycled.

Description

technical field [0001] The invention relates to the technical field of electrical safety, in particular to an oil-immersed arc suppression coil. Background technique [0002] With the accelerated pace of social and economic development, all walks of life are changing with each passing day. All kinds of electrical equipment have been developed and applied to various occasions. Among them, the oil-immersed arc suppression coil has become the key equipment and is widely used in many occasions, such as airports, hospitals or shopping malls and other places that require a large amount of power supply. At present, the arc suppression coil technology of substations is also constantly improving and has developed into The current form of automatic compensation inductive current. However, the existing oil-immersed arc suppression coils are generally prone to magnetic saturation, and the safety and reliability need to be further improved. In view of this, there is an urgent need to ...
