Description

송 변전설비의 가스절연개폐장치용 가스밸브 오 조작 감지장치{incorrect open sensing device for gas insulated swichgear of power transmission equipment}Incorrect open sensing device for gas insulated swichgear of power transmission equipment

본 발명은 가스절연개폐장치(GIS : Gas Insulated Swichgear)에 관한 것으로써, 상세하게는 송 변전설비 중 송전이 되는 송 변전설비에 설치된 가스절연개폐장치의 가스밸브를 개방시킴에 의해 발생될 수 있는 절연파괴에 따른 고장을 방지할 수 있게 한 송 변전설비의 가스절연개폐장치가스밸브 오 조작 감지장치에 관한 것이다. The present invention relates to a gas insulated switchgear (GIS: Gas Insulated Swichgear), and more specifically, which can be generated by opening a gas valve of a gas insulated switchgear installed in a transmission substation, which is the transmission of the transmission substation. The present invention relates to a gas insulated switchgear gas valve malfunction detection device of a transmission substation which makes it possible to prevent breakdown due to insulation breakdown.

전력수요의 증가에 따라 송 변전설비는 점차 대용량화 및 고 전압화 되는 추세인 반면에, 도시의 공장 밀집지대 또는 도심지에 위치하고 있는 송 변전설비는 대지가격의 상승 등으로 필요한 면적확보에 어려움이 있으며 그밖에 도심의 먼지, 공해 등에 따른 오염에 대한 안전문제가 심각해지고 있다. As power demand increases, transmission substations are gradually increasing in capacity and high voltage, while transmission substations located in urban factories or urban areas have difficulty in securing necessary areas due to rising land prices. The safety problems of pollution caused by dust and pollution in the city are becoming serious.

즉, 고 전력을 전송하기 위해서는 전력선 사이의 거리가 충분히 이격된 상태를 유지하고 있어야 하나, 이렇게 전력선 사이의 거리를 충분히 확보하기 위해서는 많은 공간을 차지하므로 이를 개선하기 위해 즉, 전력선 사이의 거리가 멀리 이격되지 않은 상태에서도 전력선 사이의 절연이 충분히 이루어지게 함으로서 전력선을 밀집시켜 설치할 수 있는 방법이 개발되고 있다. In other words, in order to transmit high power, the distance between power lines should be kept sufficiently separated, but in order to improve the distance between power lines, it takes up a lot of space to improve this, that is, the distance between power lines is far away. A method for compacting and installing power lines has been developed by providing sufficient insulation between power lines even when they are not spaced apart.

이와 같은 문제를 해결하기 위하여 근래에는 가능한 한 소형의 고전압 변전설비를 요구하게 되었으며 이에 따라 변전소를 구성하는 모든 송 변전설비에 높은 절연성을 갖는 6불화유황(SF6)가스를 이용한 가스절연개폐장치(Gas Insulated Swichgear : 이하, "GIS"라 통칭한다.)가 많이 채용되고 있다.In order to solve such a problem, in recent years, as small as possible a high voltage substation equipment has been required, according to the gas insulation switchgear (SF6) gas using sulfur hexafluoride (SF6) gas having high insulation to all transmission substations constituting the substation Insulated Swichgear (hereinafter referred to collectively as "GIS") is often employed.

GIS는 차단기, 단로기, 모선, 접지 개폐기, 변성기를 SF6가스로 충진된 탱크내에 완전히 밀폐 내장하고 있으므로 종래 변전설비와 같이 충전부가 노출되지 않고, 설치면적이 크게 줄어들며, 환경과의 조화, 고 신뢰성, 안전성, 설치공기의 단축 등의 장점을 가지고 있어 그 이용이 늘어가고 있다. Since GIS is completely sealed inside breaker, disconnector, busbar, ground switch and transformer in tank filled with SF6 gas, GIS is not exposed like charging station, and installation area is greatly reduced, harmonizing with environment, high reliability, Its advantages include safety and shortening of installation air, and its use is increasing.

이러한 GIS를 구비한 송 변전설비는 노후 되거나 고장 등을 원인으로 유지 보수가 요구되며, 이렇게 유지, 보수를 위해서는 GIS를 개방하여야 한다. Transmission substations equipped with such GIS require maintenance due to obsolescence or failure, and the GIS must be opened for maintenance and repair.

이렇게 송 변전설비를 점검 또는 보수하는 과정에서 모든 송 변전설비를 차단하여 전력을 단전시키면 정비가 필요하지 않은 지역까지 전기의 공급이 이루어지지 않아 많은 혼란이 야기됨으로, 점검이나 보수를 위한 송 변전설비만을 휴전한 상태에서 작업이 이루어지고, 작업자는 이 휴전된 송전선의 GIS를 개방하여야 한다. In the process of inspecting or repairing transmission substations, if all power transmission substations are cut off and the power is cut off, electricity is not supplied to the area where maintenance is not necessary, causing a lot of confusion. The work is to be carried out with the bays cease-fire, and the operator must open the GIS of this discontinued transmission line.

그러나 작업자가 휴전된 설비와 통전되고 있는 설비를 구분하지 못하고 통전 중인 송전선의 GIS를 개방하는 일이 종종 발생하고 있으며, 이렇게 통전된 송전선 의 GIS를 개방할 경우 절연 파괴가 발생되어 정전은 물론 설비가 손상되거나 화재를 일으키는 문제가 있었다. However, workers often open the GIS of the transmission line in power supply without distinguishing the equipment from electricity supply and the equipment being energized.In case of opening the GIS of the power transmission line in this state, insulation breakdown occurs, so that the power failure as well as the equipment There was a problem of damage or fire.

본 발명은 상기와 같은 종래 기술의 문제를 해소하기 위해 개발된 것으로써, 송 변전설비에 전기가 흐르는 상태에서 가스절연개폐장치를 개방하고자 할 경우에는 이를 작업자에게 알려 통전중인 송 변전설비의 가스절연개폐장치 가스밸브를 개방하지 않게 한 가스절연개폐장치의 가스밸브 오 조작 감지장치에 관한 것이다. The present invention has been developed to solve the problems of the prior art as described above, if you want to open the gas insulated switchgear in the state of electricity flowing in the power transmission facilities, to inform the worker that the gas insulation of the power transmission facilities under current Switching device The present invention relates to a gas valve malfunction detection device of a gas insulated switchgear which does not open the gas valve.

도시한 바와 같이 본 발명에 따른 가스절연개폐장치 가스밸브의 오 조작 감지장치는 송 변전설비에 가압되었는지 여부를 감지하기 위한 송전감지수단(1)과, 송 변전설비의 가압여부에 따라 경고음이나 빛을 발하는 알람수단(3)과, 밸브개방제한수단(2)을 포함하여 구성된다. As shown, the malfunction detection device for the gas insulated switchgear gas valve according to the present invention includes a power transmission detecting means (1) for detecting whether or not the pressurized power transmission facility is pressurized, and a warning sound or light depending on whether the power transmission facility is pressurized. It comprises an alarm means (3) and a valve opening limiting means (2) for emitting.

즉, 본 발명에 따른 가스절연개폐장치 가스밸브의 오 조작 감지장치는 절연 가스가 저장된 가스절연개폐장치를 구비한 송 변전설비에 있어서, 송전선에 전기가 흐르는 지 여부를 감지하기 위한 송전감지수단(1)과 ; 상기 가스절연개폐장치에 설치되어 내부에 저장된 절연가스를 배출하는 배출밸브(2a)에 설치되어 배출밸브의 개방을 제한하는 밸브개방제한수단(2)과 ; 상기 밸브개방제한수단(2)에 설치되어 상기 송전감지수단(1)에서 송전선에 전기가 흐르는 것을 감지한 상태에서 밸브개방제한수단(2)이 해제되면 접점이 접속되는 스위치(3)와 ; 상기 스위치(3)가 접속되면 전원을 공급받아 오 조작을 알리는 알람수단(4)을 포함하여 구성된다. That is, a malfunction detection device for a gas insulated switchgear gas valve according to the present invention is a transmission transformer having a gas insulated switchgear having an insulating gas stored therein, the power transmission sensing means for detecting whether electricity flows through the power line ( 1) and; Valve opening limiting means (2) installed in the gas insulated switchgear and installed in a discharge valve (2a) for discharging the insulating gas stored therein to limit the opening of the discharge valve; A switch (3) installed at the valve opening limiting means (2), the contact of which is connected when the valve opening limiting means (2) is released in a state in which electricity is transmitted to the power transmission line by the power transmission detecting means (1); When the switch (3) is connected it is configured to include an alarm means (4) for receiving a power supply to inform the operation.

도 1은 본 발명의 가스절연개폐장치 가스밸브의 오 조작 감지장치의 블록도로서, 밸브개방제한수단(2)은 가스절연개폐장치에 구성된 가스 배출밸브(20)에 설치된다. 1 is a block diagram of a malfunction detection device for a gas insulated switchgear gas valve according to the present invention, wherein the valve opening limiting means 2 is provided in a gas discharge valve 20 configured in the gas insulated switchgear.

상기의 가스절연개폐장치는 이미 잘 알려진 것으로 이에 대한 상세한 설명은 생략한다. The gas insulated switchgear is well known, and a detailed description thereof will be omitted.

상기 송전감지수단(1)은 송전선이나 송 변전설비에 전기가 공급되었지 여부를 감지하기 위한 수단으로 전압감지센서나 전류감지센서가 사용될 수 있다. The power transmission sensing means 1 may be a voltage sensing sensor or a current sensing sensor as a means for detecting whether electricity is supplied to a power transmission line or a power transmission equipment.

상기 송전감지수단(1)에서 송전선이나 송전 설비에 전기가 흐르고 있는 것으로 인지한 상태에서 상기 밸브개방제한수단(2)이 개방되면 상기 스위치(3)의 접점이 접속되고 이렇게 스위치(3)가 온(on)되면 상기 알람수단(4)에 전기가 공급되어 알람수단(4)이 작동하게 된다. When the valve opening limiting means 2 is opened in the state where the power transmission sensing means 1 recognizes that electricity is flowing to the power transmission line or the power transmission equipment, the contact of the switch 3 is connected and thus the switch 3 is turned on. When it is turned on, electricity is supplied to the alarm means 4 so that the alarm means 4 operates.

이에 따라 작업자는 해당 송전선 또는 송 변전설비는 정비나 수리의 대상이 아님을 인식하여 해당 밸브(20)를 개방하지 않게 되며, 이에 따라 전기가 가압된 송전선이나 송 변전설비에 설치된 가스절연개폐장치의 가스밸브를 개방하지 않게 된다. Accordingly, the operator recognizes that the transmission line or transmission substation is not subject to maintenance or repair, and does not open the corresponding valve 20. Accordingly, the operator of the gas insulation switchgear installed in the electricity pressurized transmission line or transmission substation facility Do not open the gas valve.

상기 알람수단(3)은 장소나 또는 작업자가 인식할 수 있는 상황 등을 고려하여 램프 또는 스피커 중 어느 하나를 설치하거나 램프와 스피커를 모두 설치할 수 있다. The alarm means 3 may be installed any one of the lamp or speaker in consideration of the location or the situation that can be recognized by the operator, or may install both the lamp and the speaker.

즉, 해당 송전선 또는 송 변전설비가 설치된 장소가 소음이 많이 발생하는 장소일 경우에는 램프를 설치하여 작업자가 눈으로 확인할 수 있게 하고, 눈으로 램프를 확인할 수 없는 장소일 경우에는 스피커를 설치하여 청각으로 알람 신호를 확인할 수 있게 할 수 있으나 상황에 따라 확인 가능한 감각이 달라질 수 있으므로 램프와 스피커를 모두 설치함이 바람직하다. In other words, when the power line or transmission substation is installed in a place where there is a lot of noise, install a lamp so that the operator can check it visually. It is possible to check the alarm signal, but it is preferable to install both the lamp and the speaker because the sense that can be checked depending on the situation.

상기 밸브개방제한수단(2)은 밸브(20)의 개방을 제한하는 역할을 하는 것으로 밸브(20)에 구비된 작동손잡이(20a)를 임의로 작동시키지 못하게 한다. The valve opening limiting means (2) serves to limit the opening of the valve 20 to prevent the operation handle (20a) provided in the valve 20 to operate arbitrarily.

즉, 작동손잡이(20a)를 작동시키기 위해서는 상기 밸브개방제한수단(2)을 먼저 개방하여 작동손잡이(20a)를 작동시킬 수 있는 상태가 되어야 한다. That is, in order to operate the operation handle 20a, the valve opening limiting means 2 must first be opened to operate the operation handle 20a.

따라서, 상기 송전감지수단(1)에서 감지된 송전선 또는 송 변전설비에 전기가 가압되었는지 여부를 확인하여 송전감지수단(1)에서 휴전된 상태를 확인한 후 상기 밸브개방제한수단(2)을 개방하고 밸브(20)를 개방함으로서 전기가 가압된 송전선 또는 송 변전설비가 설치된 가스절연개폐장치의 가스밸브를 개방시키는 오류를 범하지 않게 된다. Therefore, after checking whether the electricity is pressurized by the transmission line or the transmission substation facility detected by the power transmission detecting means 1, after checking the state of power interruption in the power transmission sensing means 1, the valve opening limiting means 2 is opened. By opening the valve 20, an error of opening the gas valve of the gas insulated switchgear in which the electricity is pressurized or the transmission line or the power transmission facility is installed.

상기 밸브개방제한수단(2)은 다양하게 변형하여 실시 할 수 있으나, 도 2 내 지 도 4에 도시한 바와 같이 상기 배출밸브(20)의 작동손잡이(20a)를 감싸도록 설치되고 개방된 부분에 상기 스위치(3)가 설치된 본체(21)와 ; 상기 본체(21)에 대하여 개폐 가능하게 설치되어 개폐에 따라 상기 스위치(3)의 접점을 개폐하는 뚜껑(22)으로 구성할 수 있다. The valve opening limiting means 2 may be variously modified, but as shown in FIGS. 2 to 4, the valve opening limiting means 2 may be installed and opened to surround the operation handle 20a of the discharge valve 20. A main body 21 provided with the switch 3; The main body 21 may be configured to be opened and closed, and may be configured as a lid 22 for opening and closing the contact of the switch 3 in accordance with the opening and closing.

이렇게 밸브개방제한수단(2)의 본체(21)와 뚜껑(22)은 닫혀진 상태에서 자물통 등의 잠금수단에 의해 잠겨지며, 뚜껑(22)이 닫힌 상태에서 상기 스위치(3)는 오프(off)된 상태를 유지하고 있으며, 이에 따라 알람수단(4)에는 전기가 공급되지 않게 된다. In this way, the main body 21 and the lid 22 of the valve opening limiting means 2 are locked by a locking means such as a lock in the closed state, and the switch 3 is turned off in the closed state of the lid 22. In this state, the alarm means 4 is not supplied with electricity.

그러나 잠금수단을 해제한 후 뚜껑(22)을 열면 스위치(3)가 온(on)되어 알람수단(4)에 전기가 공급되어 알람수단(4)이 작동하게 된다. However, when the lid 22 is opened after releasing the locking means, the switch 3 is turned on to supply electricity to the alarm means 4 to operate the alarm means 4.

물론 알람수단(4)이 작동할 때는 송전선이나 송 변전설비에 전기가 가압 되었을 때이고, 송전선이나 송 변전설비에 전기가 흐르지 않을 경우에는 알람수단(4)이 작동하지 않게 된다. Of course, when the alarm means (4) is operating when the electricity is pressurized on the transmission line or transmission substation equipment, when the electricity does not flow in the transmission line or transmission substation equipment, the alarm means (4) will not operate.

상기 밸브개방제한수단(2)은 다양하게 변형하여 실시할 수 있다. The valve opening limiting means 2 can be implemented in various modifications.

즉, 도 2 및 도 3에 도시한 바와 같이 뚜껑(22)이 상하로 개폐될 수 있게 하거나 도 4에 도시한 바와 같이 수평으로 개폐되게 구성할 수 있다. That is, the lid 22 can be opened and closed vertically as shown in Figures 2 and 3, or can be configured to open and close horizontally as shown in FIG.

또한, 도면에서는 본체(21)와 뚜껑(22)이 힌지결합된 것을 일예로 도시하였으나 서로 분리하여 구성할 수도 있다. In addition, in the drawings, the main body 21 and the lid 22 are illustrated as an example hinged but may be configured separately from each other.

또한, 상기 밸브개방제한수단(2)은 상기 배출밸브(20)의 일측에 설치된 고정대(20b)와 개폐손잡이(20a) 사이에 설치된 전자봉인(23)으로 구성할 수도 있다. In addition, the valve opening limiting means (2) may be composed of an electromagnetic seal (23) provided between the fixing stand (20b) and the opening and closing handle (20a) provided on one side of the discharge valve (20).

즉, 상기 밸브개방제한수단(2)을 전자봉인(23)으로 구성하고, 이 전자봉인(23)이 송전감지수단(1)에서 송전선이나 송전 설비에 전기가 흐르고 있는 상태로 인지된 상태에서 해제되면 상기 알람수단(4)이 작동되게 할 수 있다. That is, the valve opening limiting means 2 is constituted by an electronic seal 23, and the electronic seal 23 is released in a state where electricity is flowing to the power transmission line or the power transmission equipment by the power transmission sensing means 1. The alarm means 4 can be activated.

상기 전자봉인(23)은 이미 봉인(封印) 수단으로 이미 잘 알려진 것으로 이에 대한 상세한 설명은 생략한다. The electronic seal 23 is already well known as a seal (封印) means that detailed description thereof will be omitted.
