Description

가스차단기의 고온 가스 배출장치{Apparatus for Hot Gas Exhaustion of Gas Insulation Switch}Apparatus for Hot Gas Exhaustion of Gas Insulation Switch

본 발명은 전류를 통전시키기 위해 이동아크접점과 고정아크접점이 분리할 때 아크가 발생되며, 이 고온의 가스를 고정아크접점의 후방에 결합된 배출관을 통해 외부로 배출시키기 위한 가스차단기의 고온 가스 배출장치를 제공한다.According to the present invention, an arc is generated when the moving arc contact point and the fixed arc contact point are separated to conduct current, and the hot gas of the gas circuit breaker for discharging the hot gas to the outside through the discharge pipe coupled to the rear of the fixed arc contact point. Provide a discharge device.

일반적으로 가스차단기(GIS:Gas Insulation Switch)는 변전소 등과 같이 전류가 흐르는 회로를 갖는 설비에서 사고, 단락 등의 이상상태에서도 선로에 안전하게 개폐함으로써, 전력계통을 보호한다.In general, a gas insulation switch (GIS) protects an electric power system by safely opening and closing the line even in an abnormal state such as an accident or short circuit in a facility having a current flowing circuit such as a substation.

따라서 가스차단기는 전력개통의 운전 및 보수를 위하여 지속적이고 반복적인 개폐가 요구되는 개폐장치이다.Therefore, the gas circuit breaker is a switchgear that requires a continuous and repeated opening and closing for the operation and maintenance of the power opening.

이러한 종래의 가스차단기는 내부에 SF6 가스가 충진되는 금속외함에 고정되는 고정아크접점(10)과, 고정아크접점(10)에 발생되는 전계의 전위차를 감쇄시키는 쉴드(12)와, 유압장치(22)에 의해 상하로 이동하며, 일정 깊이의 내부접점(21)을 갖는 이동아크접점(20)과, 이동아크접점(20)의 내부접점(21)에 삽입 결합되며, 아크전류를 유도하는 아크접점(14), 아크접점(14)의 후방에 결합되는 주물도체(16) 와, 전류를 통전시키기 위해 이동아크접점(20)에 결합되는 제 1도체(25)와, 전류의 통전을 위해 고정아크접점(10)에 결합된 주물도체(16)에 결합되는 제 2도체(15)를 포함한다.The conventional gas circuit breaker includes a fixed arc contact point 10 fixed to a metal enclosure filled with SF6 gas therein, a shield 12 for attenuating the potential difference between the electric field generated at the fixed arc contact point 10, and a hydraulic device. 22) is moved up and down, and inserted and coupled to the moving arc contact 20 having an internal contact 21 of a predetermined depth, and the internal contact 21 of the moving arc contact 20, the arc to induce an arc current A contact conductor 14, a casting conductor 16 coupled to the rear of the arc contact 14, a first conductor 25 coupled to the movable arc contact 20 to conduct current, and fixed for conduction of current. And a second conductor 15 coupled to the cast conductor 16 coupled to the arc contact 10.

그리고 이동아크접점(20)은 내부에 SF6가스가 압축된 상태로 충진시키기 위한 파퍼실린더(24) 및 파퍼피스톤(23)과, 파퍼실린더(24)의 출구측에서 가스의 분출을 우한 노즐(22)을 갖는다.And the moving arc contact point 20 is a nozzle for filling the gas at the outlet side of the popper cylinder 24 and the papper piston 23 and the popper cylinder 24 for filling the SF6 gas in a compressed state therein ( 22).

종래의 가스차단기는 유압장치의 작동으로 이동아크접점이 고정아크접점 쪽으로 이동하게 되면 아크접점과 내부접점의 접촉이 이루어지고, 고정아크접점과 전기 접촉의 이루어진다. 접촉 차단 시 이동아크접점과 고정아크접점이 먼저 접촉이 끊어지고, 내부접점과 아크접점이 나중에 끊어진다. 이때 내부접점과 아크접점의 끊김 시 아크가 발생된다. 따라서 이러한 아크는 가스에 열을 전도하여 뜨거운 상태의 가스를 만든다.In the conventional gas circuit breaker, when the moving arc contact moves toward the fixed arc contact by the operation of the hydraulic device, the arc contact and the internal contact are made, and the fixed arc contact and the electrical contact are made. In case of contact breaking, the moving arc contact point and the fixed arc contact point are disconnected first, and the internal contact point and arc contact point are disconnected later. At this time, arc is generated when internal contact and arc contact are disconnected. This arc thus conducts heat to the gas, creating a hot gas.

그러나 종래의 가스차단기는 고정아크접점과 이동아크접점이 끊어지면서 아크가 발생되고, 이것에 의한 이 열 가스가 파퍼실린더와 피스톤에 의해 노즐을 통하여 고정아크접점을 지나 도체로 향하게 되어 도체의 절연 성능 저하가 되어 지락이 발생하는 문제점이 있다.Conventional gas circuit breakers, however, generate arcs by breaking the fixed arc contact point and the moving arc contact point, and this heat gas is directed to the conductor through the fixed arc contact point through the nozzle by the pop cylinder and the piston, thereby insulating the conductor. There is a problem that a ground fault occurs due to deterioration.

본 발명은 상기와 같은 문제를 해결하기 위해 창출된 것으로서, 보다 상세하게는, 대전류 차단후의 열 가스의 흐름이 의도된 방향으로 흐를 수 있도록 조정 및 분산하여 열 가스의 집중에 의해 전계취약부가 생기지 않게 하여 열 가스를 효율적으로 냉각시킬 수 있으며, 가스차단의 대전류 차단 시 절연성능이 우수한 가스차단기의 고온 가스 배출장치를 제공한다.The present invention has been made to solve the above problems, and more specifically, to adjust and disperse so that the flow of the heat gas after the high current flows in the intended direction so that the field weakening portion is not generated by the concentration of the heat gas. It is possible to cool the heat gas efficiently, and provides a high temperature gas discharge device of the gas circuit breaker with excellent insulation performance when the large current blocking of the gas blocking.

그리고 상기 홀은, 크기가 크게 형성되며, 상기 고온의 가스를 분산되게 배출시키는 금속망을 포함하는 것이 바람직하다.The hole may be formed to have a large size and include a metal net for discharging the hot gas to be dispersed.

본 발명은 고정아크접점과 쉴드의 후방에 홀을 갖는 배출관을 결합시켜 아크 발생 시 고온의 열을 전달받은 가스를 쉴드의 외부로 배출되게 하여 고온의 열 가스를 냉각시키며, 흐림이 유리한쪽으로 흐르게 하여 절연성능이 저하되는 것을 방지하며, 이렇게 절연성능의 저하를 방지함으로써, 가스차단기의 과전압 발생을 방지할 수 있는 효과를 제공한다.The present invention combines a fixed arc contact point and the discharge pipe having a hole in the rear of the shield to discharge the gas received high temperature heat to the outside of the shield when the arc is generated to cool the high temperature heat gas, the cloudy flow to the advantageous side It is possible to prevent the deterioration of the insulation performance and to prevent the deterioration of the insulation performance, thereby providing the effect of preventing the overvoltage of the gas circuit breaker.

In addition, the fixed arc contact 110 is in electrical contact with the second conductor 119, one side of which is inserted from the outside of the metal enclosure 1, the other side is in contact with the moving arc contact 120, the current is energized.

이동아크접점(120)은 금속외함(1) 외부에서 삽입되는 제 1도체(129)와 접속되며, 축방향으로 이동하면서 아크접점(112)을 감싸도록 접촉되는 내부접점(128)이 형성된다.The moving arc contact point 120 is connected to the first conductor 129 which is inserted from the outside of the metal enclosure 1, and the inner contact point 128 is formed to be in contact with the arc contact 112 while moving in the axial direction.

또한 이동아크접점(120)은 축방향으로 이동되게 하는 유압장치(122)를 포함하며, 이런 유입장치(122)는 이동아크접점(120)이 축방향으로 이동시켜 고정아크접점(110)과 접촉되게 하거나 접촉 해제되게 하여 접점을 개폐시킨다.In addition, the movable arc contact 120 includes a hydraulic device 122 to be moved in the axial direction, this inlet device 122 is moved in contact with the fixed arc contact 110 by moving the movable arc contact 120 in the axial direction. Contact or release contact to open or close the contact.

이런 이동아크접점(120)은 내부에 SF6가스가 압축된 상태로 충진시키기 위한 파퍼실린더(124) 및 파퍼피스톤(123)과, 파퍼실린더(24)의 출구측에서 가스의 분출을 우한 노즐(128a)을 갖는다.The moving arc contact point 120 is a nozzle for filling the gas at the outlet side of the popper cylinder 124 and the popper piston 123 and the popper cylinder 24 for filling in the compressed state of SF6 gas therein ( 128a).

아크접점(112)은 이동아크접점(120)의 내부접점(128)에 삽입되며, 고정아크접점(110)과 이동아크접점(120)의 접촉한다.The arc contact 112 is inserted into the inner contact 128 of the movable arc contact 120, the contact of the fixed arc contact 110 and the moving arc contact 120.

배출관(130)은 고정아크접점(110)을 감싸고 있는 쉴드(118)의 후방에 결합된다. 이러한 배출관(130)은 고온의 열 가스를 배출시키기 위한 홀(132)을 포함하며, 이 홀(132)은 배출관(130)의 측면과 후방으로 형성되며, 열 가스의 분산을 위한 금속망(134)을 포함한다. 그리고 배출관(130)의 후방에 제 2도체(119)가 결합되어 전류를 통전시킨다.The discharge pipe 130 is coupled to the rear of the shield 118 surrounding the fixed arc contact (110).
