Embodiment Construction

[0046] In the description of the embodiments, it should be understood that when a layer (or film), region, pattern or structure is considered to be on another substrate, another layer (or film), another region, another spacer or When another pattern is "on" or "under", it may be "directly" or "indirectly" on another substrate, layer (or film), region, pad or pattern, or there may also be one or more a middle layer. Furthermore, the positions of such layers have been described with reference to the drawings.

[0047] The thickness and size of each layer shown in the drawings may be exaggerated, omitted, or schematically drawn for convenience or clarity. Additionally, the size of elements does not utterly reflect an actual size.

[0048] Hereinafter, a bypass switch for high voltage DC power transmission according to an embodiment will be described in more detail with reference to the accompanying drawings.

Abstract

A bypass switch for high voltage direct current (HVDC) transmission is provided. The bypass switch includes a housing, a fixed contactor disposed in the housing and electrically connected to a first portion of a HVDC transmission circuit, a movable contactor movably disposed in the housing at a position spaced apart from the fixed contactor and electrically connected to a second portion of the HVDC transmission circuit, an insulation member coupled to a side of the movable contactor, an explosive actuator disposed at one side of the insulation member and exploded according to an electrical signal, and a piston mechanism which is moved by the force of gas generated due to the explosion of the explosive actuator, applies force to move the insulation member, and allows the fixed contactor and movable contactor to be electrically connected to each other.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2015-0004380 (filed January 12, 2015) under Title 35 USC Sections 119 and 365, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to bypass switches, and in particular, to high-speed short-circuit bypass switches for high-voltage direct current transmission. Background technique [0004] High-voltage direct current (HVDC) transmission refers to a power transmission method in which alternating current (AC) power generated from a power plant is converted into direct current (DC) power and transmitted by a transmission substation, while the transmitted DC The electricity is then converted back to AC electricity at the step-down substation to supply the electricity. [0005] HVDC power transmission system is suitable for submarine cable power transmission, long-distance large-capacity pow...
