Embodiment Construction

[0018] To facilitate the understanding of the embodiments, principles and features of the present invention, they are explained below in connection with their implementation in the illustrative embodiments. In particular, the supports in air-core reactors are partly made of high-resistivity materials such as dielectric materials (e.g., porcelain, glass fiber composites) and partly made of high-resistivity and low-conductivity materials such as non-ferrous materials (e.g., austenitic materials). They are described in the context of the formation of stainless steels). However, embodiments of the invention are not limited to use in the devices or methods described.

[0019] The components and materials that make up the various embodiments described below are intended to be illustrative, not restrictive. Many suitable components and materials that can perform the same or a similar function as the materials described herein are intended to be within the scope of embodiments of the...

Abstract

A cradle (200) to mount a coil (405) of an electric power line reactor (400) is provided. The cradle (200) includes a plurality of a pair of opposing arms (215(1-4)). Each arm 215 has a free end (225(1-4)) and an end coupled to a hub (220). The free end (225) of each arm (215) is configured to be coupled to a bearing assembly. The cradle (200) further includes a plurality of outer members (235(1-4)). The free ends of each pair of adjacent arms (215(1-2)) of the plurality of a pair of opposing arms (215(1-4)) are coupled to a corresponding outer member (235) of the plurality of outer members (235(1- 4)). At least one outer member (235) of the plurality of outer members (235(1-4)) is formed from a dielectric material and the plurality of a pair of opposing arms (215(1-4)) being formed from amaterial that enables the cradle (200) to support weight of the coil (405).

Description

technical field [0001] Aspects of the present invention relate primarily to dry air core reactors of the type used in utility and power applications, and more particularly to use with alternating current (AC) air core reactors but may also be applicable to direct current (DC) air core reactors bracket. Background technique [0002] In utility substations, all air-core reactors are at line potential (line voltage and line current) and need to be isolated from ground and other phases by insulators. There are two main types of galvanic insulators: porcelain and composite. For many types of devices, the strength limit is largely determined by the bending of the insulator. Flexural strength is often characterized by a quantity known as "cantilever strength". Porcelain insulators are slightly deficient in cantilever strength, while composites are quite strong in cantilever strength. One of the devices that can be installed in a typical utility substation is the air core reacto...
