Isolating switch and manufacturing method

Abstract

Disclosed are an isolating switch (100) and a method of manufacturing the isolating switch (100). The isolating switch (100) includes conductive arms (110) pivotally coupled to each other, and conductive contact fingers (111). The conductive contact fingers (111) have two opposite ends (115, 116) and an elastic portion (113) located between the two opposite ends (115, 116), and each conductive contact finger (111) passes through the The fasteners (112) at its two opposite ends (115, 116) are fixed to the corresponding conductive arms (110) so that their elastic parts (113) press against the conductive arms (110). In response to the conductive arms (110) pivoting towards each other and clamping the electrical contacts (200) suspended at the busbars above the disconnect switch (100), the conductive arms (110) communicate with the electrical contacts via corresponding conductive contact fingers (111) The head (200) is electrically coupled. The disconnect switch (100) according to the present disclosure provides outstanding contact performance, while its material cost and 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...

Problems solved by technology

[0003] Conventional disconnectors provide contacts with acceptable mechanical, electrical and thermal performance, but are relatively expensive; and therefore there is a need in the art for high performance disconnectors with acceptable manufacturing and assembly costs
