가스절연 개폐장치의 접지개폐기{Grounding Switch of Gas Insulated SwitchGear}Grounding switch of gas insulated switchgear {Grounding Switch of Gas Insulated SwitchGear}

본 고안은 가스 절연 개폐장치(SF6Gas Insulated SwitchGear )의 접지개폐기에 관한 것이다.The present invention relates to a ground switch of a gas insulated switchgear (SF 6 Gas Insulated SwitchGear).

최근의 변전설비는 전력수요의 증가에 따라 고전압화되고 있다.In recent years, substation facilities have become high voltage as demand for electric power increases.

대도시 주변의 공장 밀집지역 또는 도심지에 변전설비를 설치하기 위해서는 토지가의 상승으로 인하여 용지구입이 점차 곤란해지고 있으며, 염해, 먼지등에 의한 절연물의 오손, 소음공해, 안전성에 대해서도 심각한 고려를 해야 한다.In order to install substation facilities in dense factories or urban areas around large cities, it is becoming increasingly difficult to purchase land due to rising land prices, and serious consideration should be given to the contamination, noise pollution, and safety of insulation due to salt, dust, etc.

또한, 산업의 고도화에 따라 인력을 수급하기가 어려우므로, 운전의 자동화, 보수의 합리화 및 설치공사의 성력화가 요구되고 있고, 건물의 지하실등에도 설치가 가능한 소형의 고전압 변전설비가 필요하게 되어, 종래 대기에 의해 도체를 절연하는 개폐기구로는 이러한 요구에 부응하지 못하게 되었다.In addition, it is difficult to supply manpower due to the advancement of the industry. Therefore, automation of operation, rationalization of maintenance and improvement of installation work are required, and a small high voltage substation facility that can be installed in a basement of a building is required. Conventionally, opening and closing mechanisms for insulating conductors by the atmosphere cannot meet this demand.

따라서, 이러한 문제점을 해결하기 위해 높은 절연력을 갖는 SF6가스를 이용하여 용적을 크게 줄인 SF6가스 절연 개폐장치(SF6Gas Insulated SwitchGear ) 즉, GIS가 개발되었다.Thus, to solve this problem, SF 6 gas insulated switchgear (SF 6 Gas Insulated SwitchGear) significantly reduced the volume by using a SF 6 gas with a high dielectric strength that is, a GIS is developed.

도1은 SF6가스 절연 개폐장치(GIS)를 나타내는 개략도이며, 전원의 3상중에서 하나의 상에 대한 GIS만 도시되어 있다,1 is a schematic diagram showing a SF 6 gas insulated switchgear (GIS), in which only the GIS for one of the three phases of the power source is shown.

도시한 바와 같이, 차단기(1)는 사고로 인하여 정격전류이상의 전류가 흐를시에 전원이 차단되는 장치로서, 상기 차단기(1)에는 압축공기 `및 수동으로 조작되어 전류를 차단하는 조작장치(2)가 결합되어 있다.As shown, the circuit breaker 1 is a device in which the power is cut off when an electric current of more than the rated current flows due to an accident, and the circuit breaker 1 is a compressed air `and manually operated to block the current 2 ) Is combined.

상기 차단기(1)의 출력측에는 차단기(1)를 통과한 전기가 다수를 다수곳으로분기시키는 분배기의 일종인 모선(3)이 결합되어 있고, 상기 차단기(1)의 입력측 및 출력측에는 회로를 개폐하거나 접속을 변경하기 위한 목적으로 사용되는 개폐기의 일종인 단로기(5)(7)가 각각 결합되어 있고, GIS의 충전부는 노출되어 있지 않으므로 보수나 점검시 외부에서 접지를 용이하게 하는 접지개폐기(9)(11)가 상기 차단기(1)의 입력측 및 출력측에 각각 결합되어 있으며, 전선에 흐르는 전류를 다운시켜 계기등으로 보내는 변류기(13)(15)가 소정위치에 결합되어 있다.On the output side of the circuit breaker 1, a bus bar 3, which is a kind of distributor for branching a plurality of electricity passing through the circuit breaker 1, is coupled, and a circuit is opened and closed on the input side and the output side of the circuit breaker 1. Or a disconnector (5) (7), which is a type of switchgear used for the purpose of changing a connection, and the earthing switch (9) which facilitates grounding from the outside during maintenance or inspection because the charging part of the GIS is not exposed. 11 is coupled to the input side and the output side of the circuit breaker 1, and the current transformers 13 and 15, which send down the current flowing through the wire and send it to the instrument, are coupled to a predetermined position.

상기 접지개폐기(9)(11)는 부주의한 조작으로 인한 우발적인 사고를 방지하기 위해 상기 단로기(5)(7) 및 상기 차단기(1)와 서로 인터록되어 있다.The ground breakers 9 and 11 are interlocked with the disconnectors 5 and 7 and the breaker 1 to prevent accidental accidents due to inadvertent operation.

상기 모선(3) 및 단로기(7)는 압축공기 또는 수동으로 조작된다.The bus bar 3 and disconnector 7 are operated by compressed air or manually.

상기 GIS의 모든 기기는 SF6가스로 충전된 탱크내에 완전히 밀폐내장되어 있으므로 종래 도전부가 대기에 노출되어 발생된 문제점(예를 들면 애자 및 부싱등의 오염이나 변전소의 위치선택, 안전등)이 없어지게 되었다.All the GIS devices are completely enclosed in a tank filled with SF 6 gas, so there is no problem caused by the exposure of the conventional conductive parts to the atmosphere (for example, contamination of insulators and bushings, location selection of substations, safety, etc.). I lost.

상기 접지개폐기(9)(11)는 그 내부에 결합된 작동레버에 조작핸들을 끼워 개폐하게 된다.The ground switch 9 (11) is opened and closed by inserting the operation handle to the operating lever coupled therein.

그런데, 접지개폐기는 지면에서 높은 곳에 위치하고 있으므로, 종래의 접지개폐기에서는 조작핸들이 불안정하게 삽입되면 설비조작의 신뢰성이 떨어지고, 조작시 조작핸들이 작동레버에서 이탈하여 추락사고의 위험이 있어 안전사고도 발생하게 된다는 문제점이 있었다.However, since the grounding switch is located at a high level from the ground, if the operation handle is unstablely inserted in the conventional grounding switch, the reliability of the operation of the equipment is lowered, and the operation handle is separated from the operating lever during the operation and there is a risk of falling accident. There was a problem that will occur.

따라서, 본 고안은 상기 문제점을 해결하기 위해 이루어 진 것으로서, 본 고안의 목적은 접지개폐기의 작동레버에 조작핸들이 정확히 결합될 뿐만 아니라 이탈를 방지하는 가스절연 개폐장치의 접지개폐기를 제공하는 데 있다.Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a grounding switch of a gas insulated switchgear which is not only precisely coupled to the operation handle of the grounding switch, but also prevents a departure.
