본 고안은 전력용 보호기기로 사용되고 있는 가스차단기의 소호용 절연노즐에 관한 것으로 특히 절연노즐의 연면거리를 증가시켜 전류 차단시 생성된 오존가스로부터 직접적인 표면 오손을 방지하고 전류차단후 회복전압에 대한 표면의 절연 강도를 증대시켜 차단효과를 증대시키는데 그 목적이 있다.The present invention relates to the insulation nozzle for the arc extinguishing of the gas circuit breaker used as a power protection device. In particular, the creepage distance of the insulation nozzle is increased to prevent direct surface contamination from ozone gas generated during current interruption and to The purpose is to increase the blocking effect by increasing the insulation strength of the surface.
종래에는 제4도에서와 같이 기체(1)의 일방에 피스톤(3)을 가진 실린더(2)를 설치하고 실린더(2)와 기체(1)에는 연통되는 통로(4)(41)를 설치하며 기체(1)의 중앙에는 가동접촉자(5)와 절연노즐(71)을 설치시키고 절연노즐(71)에는 고정 아크 접촉자(5)를 설치토록 구성되어 있는바, 이와같은 종래의 것은 각 부품들이 육불화항(SF6) 가스가 봉입된 밀폐 용기속에 넣어져 있는 상태의 구성이며 각 부품 즉. 실린더(2). 기체(1). 절연노즐(71), 가동접촉자(5)등은 외부에서 가해지는 구동력에 의해 동작하도록 되어 있다.Conventionally, as shown in FIG. 4, a cylinder 2 having a piston 3 is installed on one side of the body 1, and passages 4 and 41 communicating with the cylinder 2 and the body 1 are installed. The movable contactor 5 and the insulated nozzle 71 are provided in the center of the base 1, and the fixed arc contactor 5 is installed in the insulated nozzle 71. In this conventional method, each component is six Fluorescent Port (SF 6 ) A state in which a gas is contained in a sealed container. Cylinder (2). Gas (1). The insulating nozzle 71, the movable contactor 5, and the like are operated by a driving force applied from the outside.
이와 같은 종래의 것은 실린더(2)의 피스톤(3)이 작동함에 따라 실린더(2)내의 가스가 압축되면서 통르(4)(41)를 통하여 분출되며 이는 가동접촉자(5)와 고정접촉자(6)가 분리되면서 대전류에 의해 아크가 발생할때 통로(4)(41)를 통하여 고압. 고속으로 가스가 분출되고 이 가스에 의해서 상기 아크를 소호시키면서 전류를 차단하도록 되어 있었다.This conventional method is ejected through the cylinder (4) (41) while the gas in the cylinder (2) is compressed as the piston (3) of the cylinder (2) is operated, which is the movable contact (5) and the fixed contact (6) High pressure through the passage (4) (41) when the arc is generated by a large current while being separated. The gas was ejected at a high speed, and the gas was used to cut off the current while extinguishing the arc.
그러나. 이와같은 종래의 것은 상기와 같이 발생된 아크에 의한 아크열이 육불화황(SF6)가스를 분해시켜 오존가스를 생성하게 되고 이 오존가스가 절연물로서 제작된 절연노즐의 표면에 붙게되는 문제점이 있었으며 이에따라 절연노즐의 절연내력이 저하되고 전류가 차단된 후에도 회복전압에 의해서 절연파괴가 일어나게 되는 점등의 문제점이 있었다.But. Such a conventional problem is that arc heat generated by the arc generated as described above decomposes sulfur hexafluoride (SF 6 ) gas to generate ozone gas, and the ozone gas adheres to the surface of an insulating nozzle manufactured as an insulator. As a result, the insulation strength of the insulation nozzle was lowered, and there was a problem in that the insulation was broken by the recovery voltage even after the current was cut off.
본 고안은 상기와 같은 종래의 문제점을 감안하여 절연노즐 표면의 연면거리를 증대시키고 이로써 절연파괴를 방지하며 전류 차단후 회복전압에 대한 절연강도를 증대 시킬수 있도륵 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention is designed to increase the creepage distance of the surface of the insulating nozzle in consideration of the conventional problems as described above, thereby preventing the breakdown of the insulation nozzle and to increase the insulation strength against the recovery voltage after the current interruption. When described in detail as follows.
기체(1)에 피스톤(3)을 가진 실린더(2)를 설치하고 이들에 상호 연통되는 통로(4)(41)를 형성하며 기체(l)외 중앙에 가동접촉자(5)와 절연노즐(7)을 설치하고 절연노즐(7)에는 고정 아크 접촉자(6)를 실치한 것에 있어서, 상기 절연노즐(7)의 표면에 요철부(8)를 형성하여 절연노즐 표면의 연면거리를 증대시키도록 구성한 것이다.A cylinder (2) having a piston (3) is installed in the body (1), and the passages (4) and (41) are formed to communicate with each other. The movable contactor (5) and the insulating nozzle (7) are located at the center of the body (1). In the case where the fixed arc contactor 6 is mounted on the insulating nozzle 7, the uneven portion 8 is formed on the surface of the insulating nozzle 7 to increase the creepage distance of the surface of the insulating nozzle. will be.
이상과 같은 본 고안은 기체(1)에 설치된 가동접촉자(5)와 고정 아크 접촉자(6)를 분리시킬때 이를 사이에서 대전류에 의한 아크가 발생하게 되는데, 이때 실린더(2)의 피스톤(3)이 작동하여 실린더(2)내의 가스를 통로(4)(41)를 통해서 고속, 고압으로 분출시켜 상기의 아크를 소호시키게 되는 것으로 아크카 소호될때 아크열에 의한 육뷸화황(SF6)가스가 분해되고 이에따라 오존가스가 생성되더라도 절연노즐(7)의 표면에 요철부(8)를 형성하여 표면의 연면거리를 크게 하므로서 종래보다 절연노즐(7)의 표면 오손이 길게 감소하게 된다.When the present invention as described above separates the movable contactor 5 and the fixed arc contactor 6 installed in the body 1, an arc is generated by a large current therebetween, in which case the piston 3 of the cylinder 2 In this operation, the gas in the cylinder 2 is ejected at high speed and high pressure through the passages 4 and 41 so as to extinguish the arc. When arc car is extinguished, sulfur hexafluoride (SF 6 ) gas is decomposed by arc heat. As a result, even if ozone gas is generated, the surface unevenness of the insulating nozzle 7 is reduced by forming the uneven portion 8 on the surface of the insulating nozzle 7 to increase the creepage distance of the surface.
따라서, 상기와 같이 절연노즐(7)의 절연 연면거리를 길게 하므로서 전류차단후 회복전압에 의한 절연강도가 종래에 비하여 증대되어 차단성능을 향상시키게 되고 절연 파괴의 염려가 없게 되는 점등의 특징을 지닌것이다.Therefore, as described above, the insulation creepage distance of the insulation nozzle 7 is increased, and the insulation strength due to the recovery voltage after the current interruption is increased as compared with the conventional art, thereby improving the breaking performance and having no fear of dielectric breakdown. will be.
