Abstract

The invention discloses a power capacitor with a dry-type structure. The power capacitor (1) consists of a core assembly, a casing (3) and an end cover (4), wherein, the core assembly comprise a plurality of cores (2). The inside of a cavity formed by the casing (3) and the end cover (4), and the outer space of the cores (2) form a void structure of the atmospheric gases. By adopting the dry-type structure of the technical scheme, a product doesn't need to be filled with impregnated materials, and all that is needed is to impregnate the cores through certain production techniques and ensure the eligibility of the parameters of the cores. When the power capacitor with the structure is damaged, no liquid oozes, so that the cleanness and the safety of a using site are ensured. The dry-type structure is a developing trend of the capacitors, because the structure adapts to the needs of the current environmental protection and greatly saves materials and energy.

Description

technical field [0001] The invention belongs to the technical field of electric switch cabinets, and relates to a low-voltage compensation capacitor for an AC system. More specifically, the invention relates to a power capacitor with a dry structure. Background technique [0002] The traditional power capacitors currently used in the power industry all use impregnating material technology, that is, through certain production equipment and production processes, impregnating materials are used to fill the gaps inside the power capacitor products. [0003] This impregnation method greatly increases the weight of the product. As for the switchgear as a whole, it is required that the switchgear can bear greater weight, require higher strength and firmness, and also cause an increase in manufacturing cost and waste of materials. Moreover, a large amount of impregnating material is required for filling, resulting in an increase in product material cost. Contents of the invention...
