Embodiment Construction

[0016] The solutions described herein will now be discussed with reference to several example embodiments. These embodiments are discussed only for the purpose of enabling those skilled in the art to better understand and thus realize the technical solutions described herein, rather than for the purpose of imposing any limitation on the scope of the technical solutions.

[0017] The term "including" and variations thereof should be understood as open-ended terms meaning "including, but not limited to". The term "or" should be read as "and / or" unless the context clearly dictates otherwise. The term "based on" should be understood as "based at least in part on". The terms "one embodiment" and "an embodiment" should be read as "at least one embodiment." The term "another embodiment" should be read as "at least one other embodiment". Unless otherwise indicated or limited, the terms "mount", "connect", "support" and "couple" and variations thereof are used broadly and include di...

Abstract

A disconnector (100) and a method for manufacturing the disconnector (100) are disclosed. The disconnector (100) includes conductive arms (110) pivotally coupled with each other, and finger contacts (111). The finger contacts (111) have two opposite ends (115, 116) and an elastic portion (113) between the two opposite ends (115, 116), each of the finger contacts (111) being fixed to the respectiveconductive arm (110) by fasteners (112) at the two opposite ends (115, 116) such that the elastic portion (113) presses against the conductive arm (110). In response to the conductive arms (110) being pivoted toward each other and clamping an electrical contact (200) hanged at a bus-bar above the disconnector (100), the conductive arms (110) are electrically coupled with the electrical contact (200) via the respective finger contacts (111). The disconnector (100) according to the disclosure provides outstanding contact performances while the material costs as well as manufacturing and assembly costs are relatively low.

Description

technical field [0001] Example embodiments disclosed herein relate generally to a disconnector, and more particularly, to a disconnector for use in transmission and distribution grids and a method of manufacturing the disconnector. Background technique [0002] Disconnectors are widely used in transmission and distribution networks that conduct currents up to thousands of amperes. Disconnectors need to withstand high currents and the heat generated by such high currents. Therefore, the quality of conduction as well as heat dissipation is critical in the industry. In order to connect a component such as a transformer to the grid, a disconnector requires at least one contact to make this connection to the grid bus. The design of the contacts is very important as it directly affects the aforementioned quality and cost-effectiveness. [0003] Conventional disconnectors provide contacts with acceptable mechanical, electrical and thermal performance, but are relatively expensiv...
