지아이에스 절연가스 입출력 인벤토리 스토리지 시스템{GIS 6 fluoride sulfur gas input and output inventory storage system}GIS insulation gas input and output inventory storage system {GIS 6 fluoride sulfur gas input and output inventory storage system}

본 발명은 지아이에스(GIS) 절연가스 입출력 인벤토리 스토리지 시스템에 관한 것으로, 보다 상세하게는 발전소, 변전소 등 발송배전계통의 절연을 위해 사용되는 절연가스의 입출력을 정확하게 측정하고 관리할 수 있도록 하여 UN 기후변화 협약을 준수할 수 있도록 함으로써 국가적 위상을 높일 수 있도록 개선된 지아이에스 절연가스 입출력 인벤토리 스토리지 시스템에 관한 것이다.The present invention relates to a GIS (GIS) insulation gas input/output inventory storage system, and more particularly, to accurately measure and manage the input and output of insulation gas used for insulation of transmission and distribution systems such as power plants and substations, so that the UN climate It is about an improved GIS insulated gas input/output inventory storage system to enhance national status by making it possible to comply with the change agreement.

일반적으로, 발전소에서 생산된 특고압(765 kV, 345 kV, 154 kV)은 송전선을 타고 변전소에 공급되며, 변전소에서는 특고압이 22900 볼트(=상전압 13200 볼트)의 전압으로 낮추어져 배전선로를 통해 일반 빌딩이나 공장에 공급되고, 변전소에 공급되는 특고압의 일부는 전주에 부착된 주상 변압기, 기상 변압기를 통하여 220/380 볼트의 사용하기 쉬운 전압으로 낮추어져 주택이나 상점, 소규모의 공장 등에 공급된다.In general, the extra-high voltage (765 kV, 345 kV, 154 kV) produced in the power plant is supplied to the substation via the power transmission line, where the extra-high voltage is lowered to a voltage of 22900 volts (= phase voltage 13200 volts) to cut the distribution line. Part of the extra high voltage supplied to general buildings and factories through do.

이러한 발전소 및 송배전계통에 사용되는 모선(BUS), 가스절연 개폐장치(GIS:Gas Insulated Switchgear) 등에는 절연내력 확보를 위하여 필연적으로 절연가스인 SF6 가스가 사용된다. SF 6 gas, which is an insulating gas, is inevitably used in busbars (BUS), gas insulated switchgear (GIS), etc. used in power plants and transmission and distribution systems to secure insulation strength.

그런데, SF6 가스는 CO2 1분자 대비 22,000배의 온난화 지수를 갖는 지구온난화의 주범이기 때문에 우수한 절연성에도 불구하고 그 사용이 규제되고 있다.However, SF 6 gas is the main culprit of global warming having a warming potential of 22,000 times that of one molecule of CO 2 , so its use is regulated despite its excellent insulating properties.

예컨대, 우리나라의 경우에는 1997. 12. 도쿄 프로토콜, 2012. 12. 프랑스 캅(COP) 선언 등 유엔 기후변화 협약에 따라 SF6 가스 사용을 제한하고, 주기적으로 유엔의 실사를 받기로 협정한 바 있다. For example, in the case of Korea, the use of SF 6 gas is restricted in accordance with the United Nations climate change agreements such as the Tokyo Protocol on December 1997 and the French COP Declaration on December 12, 2012, and it has been agreed to periodically undergo UN due diligence. .

따라서, 현재 SF6 가스의 사용은 기 설치 사용되는 것들만의 유지 보수를 위해서만 허용되고 신규 시설은 허용되지 않고 있으며, 기 설치 사용되는 것들에 대해서도 SF6 가스의 사용량에 대해 주기적으로 유엔에 보고해야 하고, 실사를 받아야 한다.Therefore, the use of the current SF 6 gas is allowed only for the maintenance of only those that are used to install groups, and new facilities are not allowed, groups must periodically report to the United Nations for the use of SF 6 gas even for those used to install , must be inspected.

이와 관련하여 발전소, 변전소를 포함한 절연가스를 사용하는 발송배전계통에서 주기적인 내부 점검, 유지 보수시 절연가스를 빼내게 되는데, 이때 저장장치에 저장하면서 그 양을 측정해야 한다.In this regard, insulated gas is extracted during periodic internal inspection and maintenance from the transmission and distribution system that uses insulated gas, including power plants and substations.

이 과정에서 도 1의 예시와 같은 아날로그 압력계(10)를 이용하여 절연가스의 입출입양을 계측하고 기록하여 유엔에 보고해야 하는데, 절연가스를 빼내는데만 하루 종일 걸릴 때도 있기 때문에 일부는 공기중으로 배출시켜 빠른 처리 후 일부만 저장하고 마치 전부 기록한 것처럼 처리하는 것이 비일비재하여 심각한 문제로 알려져 있다.In this process, it is necessary to measure and record the amount of ins and outs of insulating gas using the analog pressure gauge 10 as in the example of FIG. 1 , and report it to the United Nations. It is known as a serious problem because it is not uncommon to save only a portion of the data and process it as if it were all recorded.

더구나, 아날로그 압력계(10)는 정확한 양 측정이 어려워 대충 눈대중으로 체크하고 기록하는 방식이기 때문에 누락, 불량측정에 따른 협약 미준수국이라는 오명과, 국가적 위상을 떨어뜨리는 원인이 되고 있다.Moreover, since the analog pressure gauge 10 is difficult to accurately measure the amount, it is a method of checking and recording roughly with the naked eye, causing a stigma as a non-compliant country due to omissions and defective measurements, and lowering the national status.
