Description

기중절연배전반의 접지모듈Earthing module of air insulated switchboard
본 발명은 기중절연배전반의 접지모듈에 관한 것으로서, 보다 상세하게는 주회로가 활선상태일때는 접지가 되지 않고 접지가 되지 않은 상태에서는 도어가 열리지 않도록 한 기중절연 배전반의 접지모듈에 관한 것이다.The present invention relates to a grounding module of the air-insulated switchboard, and more particularly, to a grounding module of the air-insulated switchboard that prevents the door from being opened when the main circuit is in a live state and is not grounded.
일반적으로 기중절연배전반은 공기를 매질로 사용하여 송변전설비 등에서 부하를 개폐하는 것을 기본 목적으로 한다. 그리고, 기중절연배전반은 송변전설비의 이상 작동 시에는 회로를 신속히 차단하는 역할도 수행한다.In general, the air insulated switchgear uses the air as a medium to open and close the load in a transmission and distribution facility. In addition, the air insulated switchboard also serves to quickly cut off the circuit in the event of abnormal operation of the transmission and distribution equipment.
기중절연배전반은 주회로를 활선상태로 투입하거나 단선시키기 위한 부하개폐스위치(Load Breaker Switch: LBS)와 차단기(Circiut Breaker: CB)를 포함한다. 또한, 기중절연배전반은 주회로가 단선된 상태에서 접지(earth)를 통해 기중절연배전반의 전위를 0으로 유지하기 위한 접지스위치(Earth Switch: ES)를 더 포함한다.The air-insulated switchboard includes a load breaker switch (LBS) and a circuit breaker (CB) for inputting or disconnecting the main circuit in a live state. In addition, the air-insulated switchboard further includes an earth switch (ES) for maintaining the potential of the air-insulated switchboard at zero through earth in a state in which the main circuit is disconnected.
접지스위치는 부하개폐스위치와 차단기를 통해 주회로가 차단된 상태에서 기중절연배전반의 유지 또는 보수 등을 위해 작업자가 접근하는 경우에 작업자의 안전을 보장하기 위한 장치이다.The grounding switch is a device to ensure the safety of the operator when the operator approaches for maintenance or repair of the air-insulated switchboard in the state where the main circuit is blocked through the load switch and breaker.
하지만, 주회로가 활선상태일 때 접지가 이루어지면 3상 단락 회로가 형성되어 3상 단락 전류가 흐르게 된다. 이는 기중절연배전반의 정상작동을 저해하는 문제를 발생시킨다. 또한, 기중절연배전반의 내부에 아크가 발생될 수도 있어 주회로가 활선 상태일 경우에는 접지가 이루어져서는 안된다.However, if the ground is made when the main circuit is in a live state, a three-phase short circuit is formed and a three-phase short-circuit current flows. This creates a problem that hinders the normal operation of the air insulated switchgear. In addition, since an arc may be generated inside the air-insulated switchboard, grounding should not be performed when the main circuit is in a live state.
종래의 기중절연배전반에서 부하개폐스위치와 접지스위치의 작동은 각기 독립적이다. 이로 인해 부하개폐스위치가 활선상태임에도 작업자가 접지스위치를 작동시켜 접지가 이루어질 수 있다는 단점이 있었다.In the conventional air insulated switchgear, the operation of the load switch and the ground switch is independent of each other. Due to this, even though the load switch is in a live state, there is a disadvantage that the ground can be made by the operator operating the ground switch.
또한, 작업자가 접지스위치를 작동시켜 접지가 이루어진 상태에서 부하개폐스위치를 통해 단락된 주회로를 활선 상태로 전환할 수도 있어 작업자의 특별한 주의가 없다면 큰 안전사고가 발생할 수 있다는 문제점도 있었다.In addition, there is a problem in that a large safety accident may occur if there is no special attention of the operator because the main circuit shorted through the load switch may be switched to a live state while the ground is operated by the operator operating the ground switch.
따라서 이와 같은 문제점들을 해결하기 위한 방법이 요구된다.Therefore, a method for solving these problems is required.
본 발명은 상술한 종래 기술의 문제점을 해결하기 위하여 안출된 발명으로서 주회로가 활선인 상태에서 접지스위치의 조작을 불가하게 하고, 접지스위치를 통해 접지가 된 상태에서는 부하개폐스위치의 조작을 할 수 없도록 한 접지모듈을 제공하기 위함이다.The present invention is an invention devised to solve the above-mentioned problems of the prior art, which makes it impossible to operate the ground switch while the main circuit is live, and can operate the load switch when grounded through the ground switch. The purpose is to provide a grounding module that has been prevented.

아래에서는 상기된 각각의 구성을 보다 구체적으로 설명한다.Hereinafter, each of the above-described configurations will be described in more detail.
제1개폐유닛(110)은 도어(20)에 마련되어 도어(20)의 열림과 닫힘을 조작한다. 제1개폐유닛(110)은 도어(20)의 외측으로 일부가 노출되는 키조작부(112)를 포함한다.The first opening/closing unit 110 is provided on the door 20 to manipulate the opening and closing of the door 20. The first opening and closing unit 110 includes a key operation unit 112 that is partially exposed to the outside of the door 20.
키조작부(112)에는 전술한 입력부재가 삽입될 수 있고, 미리 정해진 입력부재가 삽입되었을 경우 입력부재의 회전을 통해 열림 또는 닫힘을 선택할 수 있다.The above-described input member may be inserted into the key operation unit 112, and when a predetermined input member is inserted, it is possible to select open or closed through rotation of the input member.
본 발명의 일 실시예에서 제1개폐유닛(110)을 조작하기 위한 외부입력은 입력부재이다. 입력부재는 키조작부(112)에 삽입된 후 미리 정해진 방향으로 회전함으로 제1개폐유닛(110)을 제1상태 또는 제2상태로 설정할 수 있다.In one embodiment of the present invention, the external input for operating the first opening/closing unit 110 is an input member. After the input member is inserted into the key operation unit 112 and rotates in a predetermined direction, the first opening/closing unit 110 may be set to a first state or a second state.
본 발명의 일 실시예에서 제1상태는 열림상태로, 제2상태는 닫힘상태로 정의한다.In one embodiment of the present invention, the first state is defined as an open state and the second state is defined as a closed state.
키조작부(112)에 삽입된 입력부재가 회전하면 도어(20)의 내측공간에서 입력부재와 함께 제1회전축(114)이 회전한다. 제1회전축(114)은 회전되는 중심축을 기준으로 중심축과 멀어지는 방향으로 휘거나 접힘, 또는 그 두께가 변경되는 제1차단부(116) 및 제2차단부(118)를 포함한다. 제1차단부(116) 및 제2차단부(118)는 후술될 연동플레이트(130) 및 종동링크(152)와 유기적인 관계를 가지고 작동한다. 제1차단부(116) 및 제2차단부(118)는 연동플레이트(130)와 종동링크(152)와 함께 다시 자세하게 설명하기로 한다.When the input member inserted into the key operation unit 112 rotates, the first rotation shaft 114 rotates together with the input member in the inner space of the door 20. The first rotational shaft 114 includes a first blocking portion 116 and a second blocking portion 118 whose bending or folding, or its thickness is changed, in a direction away from the central axis based on the rotating central axis. The first blocking portion 116 and the second blocking portion 118 operate in an organic relationship with the interlocking plate 130 and the driven link 152, which will be described later. The first blocking portion 116 and the second blocking portion 118 will be described in detail again with the interlocking plate 130 and the driven link 152.
승강플레이트(120)는 도어(20)의 내측에 마련되나, 도어(20)의 전방으로 돌출되는 제2개폐스위치(122)를 포함한다. 도어(20)에는 상하로 길게 개방된 장공 형태의 제1안내구(24)가 형성되고, 제2개폐스위치(122)는 제1안내구(24)를 통해 도어(20)의 전방으로 돌출된다.The lifting plate 120 is provided inside the door 20, but includes a second opening/closing switch 122 protruding toward the front of the door 20. The door 20 is formed with a first guide opening 24 in the form of a long hole opened up and down, and the second opening/closing switch 122 protrudes toward the front of the door 20 through the first guide opening 24. .
제2개폐스위치(122)는 작업자가 손으로 조작하여 제1안내구(24)를 따라 이동시킬 수 있다. 상세하게는 제1안내구(24)는 도어(20)의 상하방향으로 형성되고, 제2개폐스위치(122)는 제1안내구(24)의 최하단에 위치하게 된다. 작업자가 제2개폐스위치(122)를 상방으로 이동시키면 제2개폐스위치(122)와 결합되어 있는 승강플레이트(120)는 도어(20)의 내측공간에서 상승한다. 그리고, 작업자가 제2개폐스위치(122)를 놓으면 승강플레이트(120)는 자중에 의해 하강하게 된다.The second opening/closing switch 122 may be moved by the operator along the first guide opening 24 by hand. In detail, the first guide opening 24 is formed in the vertical direction of the door 20, and the second opening/closing switch 122 is positioned at the bottom of the first guide opening 24. When the operator moves the second opening/closing switch 122 upward, the lifting plate 120 coupled to the second opening/closing switch 122 rises in the inner space of the door 20. Then, when the operator releases the second opening and closing switch 122, the lifting plate 120 is lowered by its own weight.
이때, 승강플레이트(120)는 제1개폐유닛(110)이 제1상태일 때 상승하여 제1위치로 이동할 수 있다. 그리고, 제1개폐유닛(110)이 제2상태일 때에는 작업자가 제2개폐스위치(122)를 올릴 수 없고 승강플레이트(120)는 아래쪽에 고정된다.At this time, the elevating plate 120 may rise to the first position when the first opening/closing unit 110 is in the first state. In addition, when the first opening/closing unit 110 is in the second state, the operator cannot raise the second opening/closing switch 122 and the lifting plate 120 is fixed at the bottom.
구체적으로는, 작업자가 제1개폐유닛(110)을 제1상태로 설정하지 않으면 승강플레이트(120)를 들어올릴 수 없게 된다. 제1개폐유닛(110)을 제1상태로 설정하는 것은 입력부재를 제1개폐유닛(110)의 키조작부(112)에 삽입한 후 미리 정해진 방향으로 돌림으로써 가능하다.Specifically, unless the operator sets the first opening/closing unit 110 to the first state, the lifting plate 120 cannot be lifted. Setting the first opening/closing unit 110 to the first state is possible by inserting the input member into the key operation unit 112 of the first opening/closing unit 110 and turning it in a predetermined direction.
연동플레이트(130)는 도어(20)의 내측에 구비된다. 연동플레이트(130)는 승강플레이트(120)의 이동에 종속되어 이동한다. 상세하게는, 승강플레이트(120)는 연동플레이트(130)를 향해 연장되는 연동부재(124)를 포함하고, 연동부재(124)는 연동플레이트(130)에 형성된 연동구(132)를 통과하여 결합된다. 따라서, 승강플레이트(120)가 상승하면 연동부재(124)가 연동플레이트(130)를 밀어올려 연동플레이트(130)도 상승하게 된다. 반대로 승강플레이트(120)를 들어올린 외력이 제거되면 연동플레이트(130)는 승강플레이트(120)와 함께 하강한다.The interlocking plate 130 is provided inside the door 20. The interlocking plate 130 moves depending on the movement of the elevating plate 120. Specifically, the lifting plate 120 includes an interlocking member 124 extending toward the interlocking plate 130, and the interlocking member 124 passes through the interlocking tool 132 formed on the interlocking plate 130 to be coupled. do. Therefore, when the lifting plate 120 rises, the interlocking member 124 pushes up the interlocking plate 130, so that the interlocking plate 130 also rises. Conversely, when the external force lifting the lifting plate 120 is removed, the interlocking plate 130 descends together with the lifting plate 120.
본 발명의 일 실시예에서 연동플레이트(130)의 상단에 걸림부(134)가 형성된다. 걸림부(134)는 전술하였던 제1개폐유닛(110)의 제1차단부(116)와 접할 수 있다.In one embodiment of the present invention, a locking portion 134 is formed at the top of the interlocking plate 130. The locking portion 134 may contact the first blocking portion 116 of the first opening and closing unit 110 described above.
제1차단부(116)는 제1개폐유닛(110)이 제1상태로 설정될 경우에 제1회전축(114)의 회전과 함께 걸림부(134)가 상하 이동하는 공간을 벗어난 위치에 배치된다.When the first opening and closing unit 110 is set to the first state, the first blocking part 116 is disposed at a position outside the space where the locking part 134 moves up and down together with the rotation of the first rotating shaft 114. .
그리고, 제1차단부(116)는 제1개폐유닛(110)이 제2상태로 설정될 경우에 제1회전축(114)의 회전과 함께 걸림부(134)의 상단과 접하여 걸림부(134)가 상부로 이동하지 못하게 한다.In addition, when the first opening/closing unit 110 is set to the second state, the first blocking portion 116 comes into contact with the upper end of the locking portion 134 with the rotation of the first rotating shaft 114, and the locking portion 134 Prevents it from moving upwards.
걸림부(134)가 제1차단부(116)에 걸려 상부로 이동하지 못하면 걸림부와 일체로 형성되는 연동플레이트(130)도 상부로 이동이 불가하고, 연동플레이트(130)와 연동부재(124)를 통해 연결된 승강플레이트(120) 또한 상부로 이동이 불가하게 된다.If the locking portion 134 is caught by the first blocking portion 116 and cannot move upward, the interlocking plate 130 formed integrally with the locking portion cannot be moved upward, and the interlocking plate 130 and the interlocking member 124 ), the lifting plate 120 connected through the same is also impossible to move upward.
도 4는 및 도 5는 본 발명의 일 실시예에 따른 접지모듈에서 제1개폐유닛의 작동상태를 도시한 것으로서, 도 4는 제2상태를, 도 5는 제1상태를 도시한 것이다.4 and 5 show the operating state of the first opening and closing unit in the ground module according to an embodiment of the present invention, Figure 4 shows the second state, Figure 5 shows the first state.
도 4 및 도 5에 도시된 바와 같이, 작업자가 제1개폐유닛(110)의 키조작부(112)를 입력부재를 통해 회전시키면 제1회전축(114)이 함께 회전한다. 또한, 제1회전축(114)의 회전과 함께 제1차단부(116)도 함께 회전하고, 제1차단부(116)는 제2상태에서 연동플레이트(130)의 걸림부(134)의 상단과 접하여 연동플레이트(130)가 상부로 이동하지 못하게 한다.4 and 5, when the operator rotates the key operation unit 112 of the first opening/closing unit 110 through the input member, the first rotation shaft 114 rotates together. In addition, along with the rotation of the first rotating shaft 114, the first blocking portion 116 also rotates, and the first blocking portion 116 and the upper end of the locking portion 134 of the interlocking plate 130 in the second state. The interlocking plate 130 is prevented from moving upward.
제2상태에서는 승강플레이트(120)가 제2위치에 위치한다. 승강플레이트(120)가 제2위치인 경우 핸들삽입공(22)은 차단된다. 따라서, 제2상태에서는 핸들조작부(142)가 외부로 노출되지 않아 핸들조작부(142)의 조작이 불가하다.In the second state, the lifting plate 120 is located in the second position. When the lifting plate 120 is in the second position, the handle insertion hole 22 is blocked. Therefore, in the second state, since the handle manipulation unit 142 is not exposed to the outside, manipulation of the handle manipulation unit 142 is impossible.
제1상태에서는 제1차단부(116)가 걸림부(134)의 상부에서 제거되어 연동플레이트(130) 및 승강플레이트(120)가 상승할 수 있다.In the first state, the first blocking portion 116 is removed from the upper portion of the locking portion 134 so that the interlocking plate 130 and the lifting plate 120 may rise.
제1상태에서 작업자가 제2개폐스위치(122)를 상부로 올리게 되면 승강플레이트(120)가 상승해 제1위치로 이동한다. 승강플레이트(120)가 제1위치로 상승하면 연동플레이트(130)도 함께 상승한다. 연동플레이트(130)가 상승함에 따라 연동플레이트(130)에 가려져 있던 핸들삽입공(22)이 개방된다. 핸들삽입공(22)은 도어(20)에 마련되며 내부에 접지유닛(140)을 조작할 수 있는 핸들조작부(142)가 배치된다.In the first state, when the operator raises the second opening/closing switch 122 upward, the lifting plate 120 rises and moves to the first position. When the lifting plate 120 rises to the first position, the interlocking plate 130 also rises. As the interlocking plate 130 rises, the handle insertion hole 22, which was hidden by the interlocking plate 130, is opened. The handle insertion hole 22 is provided on the door 20 and a handle operation part 142 capable of operating the grounding unit 140 is disposed inside.
따라서, 제1상태에서 작업자의 조작에 의해 연동플레이트(130)가 상승하고, 연동플레이트(130)로 폐쇄되어 있던 핸들삽입공(22)이 개방된다. 그리고, 핸들삽입공(22) 내부의 핸들조작부(142)가 노출된다.Accordingly, in the first state, the interlocking plate 130 is raised by the operator's operation, and the handle inserting hole 22 closed by the interlocking plate 130 is opened. Then, the handle manipulation portion 142 inside the handle insertion hole 22 is exposed.
접지유닛(140)은 핸들조작부(142)에 공구를 삽입하여 조작할 수 있다. 접지유닛(140)은 핸들조작부(142)가 미리 정해진 각도로 회전되면 접지를 수행한다.The ground unit 140 may be operated by inserting a tool into the handle manipulation unit 142. The grounding unit 140 performs grounding when the handle manipulation unit 142 is rotated at a predetermined angle.
도 6 및 도 7은 본 발명의 일 실시예에 따른 접지모듈에서 접지유닛의 작동상태를 도시한 것이다.6 and 7 show the operating state of the ground unit in the ground module according to an embodiment of the present invention.
도 6 및 도 7에 도시된 바와 같이, 접지유닛(140)은 핸들조작부(142)를 포함하고, 핸들조작부(142)가 회전됨에 따라 함께 회전하는 제2회전축(144)을 더 포함한다.6 and 7, the ground unit 140 further includes a handle manipulation unit 142, and further includes a second rotation shaft 144 that rotates together as the handle manipulation unit 142 is rotated.
제2회전축(144)은 캠부재(150)와 도어개폐레버(146)가 결합된다.The second rotation shaft 144 is a cam member 150 and the door opening and closing lever 146 is coupled.
먼저, 도어개폐레버(146)는 핸들조작부(142)를 통해 접지가 수행되지 않은 상태에서 도어(20)와 간섭되어 도어(20)가 열리지 않도록 마련된다.First, the door opening and closing lever 146 is provided so that the door 20 is not opened by interfering with the door 20 in a state in which grounding is not performed through the handle manipulation unit 142.
따라서, 도어(20)는 닫힌 상태에서 핸들조작부(142)를 상술하였던 과정을 거쳐 먼저 개방한 후 핸들조작부(142)를 조작하여 접지하여야만 열수 있게 된다.Accordingly, the door 20 can be opened only when the handle manipulation unit 142 is opened in the closed state and then opened by first operating the handle manipulation unit 142.
도 8은 본 발명의 일 실시예에 따른 접지모듈에서 제2회전축의 회전에 따라 승강하는 종동레버의 상태를 도시한 것이다.8 is a view showing a state of the driven lever ascending according to the rotation of the second rotation shaft in the ground module according to an embodiment of the present invention.
도 8에 도시된 바와 같이, 캠부재(150)는 일단이 제2회전축(144)에 고정되고 타단은 제2회전축(144)의 회전하는 중심축과 미리 정해진 간격만큼 떨어져 위치한다. 따라서, 캠부재(150)는 타단이 큰 회전반경으로 회전하게 된다. 캠부재(150)의 타단에는 종동링크(152)가 회전 가능하게 결합된다. 종동링크(152)는 미리 정해진 길이를 지니고, 하단이 캠부재(150)와 결합되어 캠부재(150)와 함께 회전된다. 종동링크(152)의 상단에는 종동레버(154)가 형성되고, 종동레버(154)는 캠부재(150)가 회전하면 상하 직선방향으로 왕복한다. 구체적으로는, 핸들조작부(142)의 조작을 통해 제2회전축(144)이 회전하여 접지상태가 되면 종동레버(154)는 하사점(bottom dead center)에 위치하고, 접지유닛(140)이 접지해제 상태일때 종동레버(154)는 상사점(top dead point)에 위치한다. As shown in FIG. 8, one end of the cam member 150 is fixed to the second rotational shaft 144 and the other end is positioned at a predetermined distance from the rotating central axis of the second rotational shaft 144. Therefore, the cam member 150 is rotated with a large radius of rotation of the other end. The driven link 152 is rotatably coupled to the other end of the cam member 150. Follower link 152 has a predetermined length, the lower end is combined with the cam member 150 is rotated with the cam member 150. A driven lever 154 is formed at an upper end of the driven link 152, and the driven lever 154 reciprocates in the vertical direction when the cam member 150 rotates. Specifically, when the second rotating shaft 144 rotates through the operation of the handle manipulation unit 142 to become a ground state, the driven lever 154 is located at the bottom dead center, and the ground unit 140 releases ground. When in the state, the driven lever 154 is located at the top dead point.
종동레버(154)가 하사점에 위치하면 전술하였던 제1회전축(114)의 제2차단부(118)와 접한다. 제1회전축(114)은 제2차단부(118)와 종동레버(154)가 접한 상태에서 회전이 불가하고, 이는 작업자가 접지상태에서 키조작부(112)에 삽입된 입력부재를 회전시키지 못하게 한다. 따라서, 접지유닛(140)이 접지상태에 있는 경우 작업자는 키조작부(112)에 삽입된 입력부재를 조작할 수 없을 뿐만 아니라, 입력부재를 키조작부(112)로부터 인출할 수도 없게 된다.When the driven lever 154 is located at the bottom dead center, it is in contact with the second blocking portion 118 of the first rotating shaft 114 described above. The first rotation shaft 114 is not rotated in the state where the second blocking part 118 and the driven lever 154 are in contact, which prevents the operator from rotating the input member inserted into the key operation part 112 in the grounded state. . Therefore, when the grounding unit 140 is in the grounded state, the operator can not only operate the input member inserted into the key manipulation unit 112, but also cannot withdraw the input member from the key manipulation unit 112.
이는 제1개폐유닛(110)과 동일한 입력부재를 사용하는 부하개폐모듈(10)이 접지가 유지된 채 활선상태로 조작되는 것을 방지하기 위함이다.This is to prevent the load switch module 10 using the same input member as the first switch unit 110 from being operated in a live line while the ground is maintained.
전술하였던 승강플레이트(120)는 상하 방향으로 형성되는 장공인 제2안내구(126)를 포함할 수 있다. 제2안내구(126)의 도어(20) 또는 함체에 고정된 돌기가 삽입될 수 있고, 이는 승강플레이트(120)가 상하 방향으로 곧게 승강할 수 있게 한다.The above-described lifting plate 120 may include a second guide 126 that is a long hole formed in the vertical direction. A protrusion fixed to the door 20 or the housing of the second guide opening 126 may be inserted, which allows the lifting plate 120 to move up and down in a vertical direction.
또한, 연동플레이트(130)도 역시 상하 방향으로 형성되는 장공인 제3안내구(136)를 포함할 수 있다. 제3안내구(136) 또한 연동플레이트(130)가 상하 방향으로 곧게 승강할 수 있게 한다.In addition, the interlocking plate 130 may also include a third guide 136 which is a long hole formed in the vertical direction. The third guide 136 also allows the interlocking plate 130 to be vertically elevated in the vertical direction.
제2안내구(126) 및 제3안내구(136)는 적어도 하나가 형성될 수 있고, 다수 개가 마련되어도 무방하다.At least one of the second guide hole 126 and the third guide hole 136 may be formed, and a plurality of guide holes may be provided.
상술한 바와 같은 구성을 지닌 본 발명에 따른 접지모듈(100)은 부하개폐모듈(10)과 제1개폐유닛(110)을 동일한 입력부재로 조작한다. 부하개폐모듈(10)이 활선상태일 때, 작업자는 제1개폐유닛(110)을 조작할 수 없어 도어(20)를 개방할 수 없다.The ground module 100 according to the present invention having the configuration as described above operates the load switch module 10 and the first switch unit 110 with the same input member. When the load opening/closing module 10 is in a live state, the operator cannot operate the first opening/closing unit 110 and cannot open the door 20.
그리고, 도어(20)는 접지가 이루어지지 않으면 접지유닛(140)의 도어개폐레버(146)가 개입되어 열리지 않는다. 또한, 접지상태에서는 키조작부(112)에 삽입된 입력부재를 인출할 수 없다.In addition, if the ground 20 is not grounded, the door opening and closing lever 146 of the grounding unit 140 is intervened and is not opened. Also, in the grounded state, the input member inserted into the key operation unit 112 cannot be withdrawn.
따라서, 기중절연 배전반(1)이 활선상태일 때 동시에 접지가 이루어질 수 없어 이상작동의 가능성이 감소하게 된다. 그리고, 접지가 이루어지지 않으면 도어(20)가 열리지 않으므로 작업자의 안전사고도 예방할 수 있다.Therefore, when the air insulated switchboard 1 is in a live state, grounding cannot be performed at the same time, so the possibility of abnormal operation is reduced. In addition, if the ground is not made, the door 20 is not opened, and thus a safety accident of the worker can be prevented.
또한, 접지상태에서는 입력부재를 인출할 수 없으므로 작업자가 접지상태를 직관적으로 인식할 수 있으므로 작업자의 실수를 줄일 수 있다.In addition, since the input member cannot be pulled out in the grounded state, the operator can intuitively recognize the grounded state, thereby reducing operator error.
이상과 같이 본 발명에 따른 바람직한 실시예를 살펴보았으며, 앞서 설명된 실시예 이외에도 본 발명이 그 취지나 범주에서 벗어남이 없이 다른 특정 형태로 구체화될 수 있다는 사실은 해당 기술에 통상의 지식을 가진 이들에게는 자명한 것이다. 그러므로, 상술된 실시예는 제한적인 것이 아니라 예시적인 것으로 여겨져야 하고, 이에 따라 본 발명은 상술한 설명에 한정되지 않고 첨부된 청구항의 범주 및 그 동등 범위 내에서 변경될 수도 있다.As described above, a preferred embodiment according to the present invention has been examined, and the fact that the present invention may be embodied in other specific forms without departing from the spirit or scope of the embodiment described above has ordinary skill in the art. It is obvious to them. Therefore, the above-described embodiments are to be regarded as illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description and may be changed within the scope of the appended claims and their equivalents.
