Description

가스절연개폐장치용 안전 파열판{Bursting disk for gas insulated switchgear}Bursting disk for gas insulated switchgear

본 발명은 가스절연개폐장치용 안전 파열판에 관한 것으로, 상세하게는 가스절연개폐장치 내부의 예기 하지 않은 고장으로 인하여 급격한 압력상승에 대응할 수 있도록, 안전한계 및 적정압력 이상으로 압력이 가해질 때 초과 압력을 안전한 외부 장소로 배출시켜, 기기의 파손을 방지하고 대형 사고나 인명피해를 방지할 수 있도록 한 가스절연개폐장치용 안전 파열판에 관한 것이다.
The present invention relates to a safety rupture plate for a gas insulated switchgear, and more particularly, in order to cope with a sudden pressure increase due to an unexpected failure in the gas insulated switchgear, an excess pressure when a pressure is applied above a safe system and an appropriate pressure. The present invention relates to a safety rupture plate for a gas insulated switchgear which discharges the gas to a safe outside place to prevent damage to the device and to prevent a large accident or human injury.

일반적으로 사용되는 가스절연개폐장치에는 절연을 목적으로 공기 내지 SF-6의 가스를 사용하게 된다. 하지만, 공기보다 SF-6 가스가 절연효과가 3배 이상이고 여기에 압력을 가하면 그 효과는 증가한다. In general, the gas insulation switchgear used is a gas of air to SF-6 for the purpose of insulation. However, SF-6 gas is 3 times more insulating than air and the effect increases when pressure is applied to it.

따라서 기존보다 적은 공간으로 절연효과를 나타낼 수 있어 가스절연개폐장치에 많이 사용되고 있는 실정이다. 하지만, 일정압력이 유지되면 문제가 발생하지 않지만 전기적 사고로 인해 쇼트가 발생할 시에는 에너지가 급증하여 온도가 상승하여 내부압력이 급격히 증가하고 압력용기는 폭발에 이르게 된다. Therefore, the present invention can be used in gas insulation switchgear as it can exhibit insulation effect with less space than before. However, if a constant pressure is maintained, no problem occurs, but when a short occurs due to an electrical accident, the energy increases and the temperature rises, the internal pressure rapidly increases, and the pressure vessel leads to an explosion.

이는 환경적이나 인명피해로 이어질 뿐 아니라 막대한 경제적 손실을 생각하면, 수천억 원이라는 천문학적, 피해는 이루 말할 수 없을 것이다. This not only leads to environmental and casualties, but also to the enormous economic loss, the hundreds of billion won in astronomical damage.

이에 가스절연개폐장치의 급격히 증가하는 압력을 해소하고자 종래기술들로서 일반 스프링식 안전밸브로는 예고치 않은 급격한 압력상승을 해결하기 힘든 경우와 다른 파열판의 경우 파열될 때의 조각들이 막힘으로 인해 원활한 압력감소가 되지 않거나 그 조각에 의한 인명피해를 입는 등의 폐단 등이 있었다.
In order to solve the sudden increase in pressure of the gas insulated switchgear, as a conventional technique, it is difficult to solve the sudden increase in pressure unforeseen by the general spring type safety valve and the smooth pressure due to the blockage of pieces when ruptured in other bursting plates. There were no reductions or damages such as loss of life due to the pieces.

본 발명은 상기와 같은 폐단을 해소하기 위해 가스절연개폐장치에 순간적으로 많은 방출이 필요한 부분이나 방출시 피해가 없는 부분에 캐스킷과 본 발명품을 밀착시켜 볼트로 고정하여 일체가 되게 형성하고 급격한 압력 상승 시에 안전하게 미리 파열되어 압력용기 전체의 파손을 방지하는데 그 목적이 있다.
The present invention is formed to be integrally fixed to the gasket and the present invention to the part in need of a large number of moments in the gas insulated switchgear device or to the part that does not cause damage during the discharge in order to eliminate the above-mentioned closed end and to form a sudden pressure The purpose is to prevent the breakage of the entire pressure vessel by rupturing safely in advance when it is raised.

본 발명은 상기의 과제를 해결하기 위하여, 박판 돔형 디스크, 보강판 돔형 디스크와 보강 도넛형 디스크로 구성된 가스절연개폐장치용 안전 파열판을 개선한 것으로, 상기의 보강판 돔형 디스크는 새로운 절단 시스템을 도입하여 톱니, 지지대, 힌지부, 개구부를 슬롯 패턴으로 절단하여 제작하였으며, 한계 압력 이상으로 압력이 상승하는 경우, 박판 돔형 디스크가 보강판 돔형디스크에 고안된 슬롯 패턴의 톱니 부분에 절단되어 끊어지고 힌지 부분만 제외하고는 나머지부분이 개방되어 SF-6 가스를 배출하는 안전 파열판을 제공하는 것이다.
In order to solve the above problems, the present invention is an improvement of a safety rupture plate for a gas insulated switchgear consisting of a thin dome disk, a reinforcement plate dome disk and a reinforcement donut disk, and the reinforcement plate dome disk introduces a new cutting system. The sawtooth, support, hinge, and opening were cut into slot patterns, and when the pressure rose above the limit pressure, the thin domed disc was cut into the sawtooth part of the slot pattern designed for the reinforcement plate dome disc, and the hinge part was cut. Except for this, the remainder is open to provide a safety rupture plate to discharge SF-6 gas.

이와 같은 본 발명은 가스절연개폐장치에 사용자의 원하는 가스 분출 위치에 부착시켜 인명피해를 없애고자 특정압력이상으로 급격히 상승하게 되었을 때 압력용기가 파손되는 것을 방지해주므로 인해 엄청난 손실이나 불편함이 방지되는 효과가 있다.

디스크 절곡부의 지름 = 116Diameter of Disk Bends 116

톱니부위 지름 = 92㎜Tooth diameter = 92 mm

지름비율= 톱니부위 지름/디스크 절곡부의 지름*100Diameter ratio = tooth area diameter / diameter of disc bend * 100

지름비율= 92/116*100=79.31%Diameter ratio = 92/116 * 100 = 79.31%

따라서 지름비율이 79.3%일 때 효과적인 설계가 되었다.
Therefore, it was an effective design when the diameter ratio was 79.3%.
