Description

conductor assembly

[0001] The present invention relates to a conductor assembly, and more specifically, to a conductor assembly capable of automatically responding to changes in height caused by ground subsidence, building subsidence, vibration, concrete shrinkage and expansion, etc.

[0002] Generally, a Gas Insulated Switchgear (GIS) is an electrical device installed between the power source and the load side of an electrical system to protect the power system and load equipment by safely interrupting the current when the circuit is artificially opened or closed under normal current conditions, or when abnormal currents such as ground faults or short circuits occur in the circuit. Such a GIS typically consists of a bushing unit that receives power from a high-voltage power source, a line DS / ES (Disconnector Switch / Earthing Switch), a Gas Circuit Breaker, a busbar DS / ES, a moving part, and a control part.

[0003] The main conductors used in the conductive paths of the ultra-high voltage equipment described above are located within a metal tank-like enclosure and vary in shape depending on their respective roles. The paths formed by these main conductors are divided into unit units, which form a single compartment by connecting conductor assemblies. This is because they must be divided into distinct units for installation and maintenance purposes. The components of these units may include tanks, spacers, conductors, and conductor connectors.

[0004] The above-described conventional conductor connection structure is disclosed in Korean Patent Publication No. 10-2011-0075823 and Korean Registered Patent Publication No. 10-2417010.

[0005] A conventional conductor connection structure is configured such that a silver-plated ring member is pressed into the part where electrical contact is made of the conductor, thereby increasing the efficiency of the silver plating process and facilitating electrical contact.

[0006] In addition, conventional conductor connection structures are configured such that the busbar conductor housed inside the enclosure is slidably coupled to the main mold, making assembly and disassembly easy.

[0007] These conventional conductor connection structures have a problem in that if ground or building subsidence occurs, the connections between conductor components may be damaged, potentially causing the power system to stop operating.

[0008] In addition, conventional conductor connection structures have the problem that in environments with uneven ground, additional foundation civil engineering work must be carried out so that installation work can be performed on a flat ground, which not only takes a long time for installation work but also increases installation costs to create the installation environment.

[0009] Accordingly, the objective of the present invention is to solve the problems of the prior art as described above by providing a conductor assembly capable of automatically adjusting the angle of an extendable conductor according to changes in ground elevation through the rotational movement of a rotating conductor and the extensional movement of an extendable conductor.

It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the embodiments of the present invention, if it is determined that a detailed description of related known components or functions would hinder understanding of the embodiments of the present invention, such detailed description is omitted.

[0035] In addition, terms such as first, second, A, B, (a), (b), etc., may be used when describing the components of the embodiments of the present invention. These terms are intended only to distinguish the components from other components, and the essence, order, or sequence of the components is not limited by the terms. Where it is stated that a component is "connected," "combined," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other component, but that another component may also be "connected," "combined," or "connected" between each component.
