Designed based on the same insulation design as, and the safety factor is manufactured relatively low, when opening and closing a large-capacity line, the opening and closing voltage of the steep waveform by the charging charge is generated.
종래의 가스절연개폐장치에 사용되는 단로기는 제 1 도에 나타낸 바와 같이, 외함(1a)내에 단순한 구조로 된 가동접촉자(6)와 고정접촉자(5)가 설치되어 가스절연 개폐장치의 단로기를 개폐하면 선로 및 모선의 충전전하를 차단하게 되는데, 이때 개폐시 급준파형의 과도한 과전압이 발생하여 가스절연 개폐장치의 외함절연단자와 절연물을 파괴하므로 기기를 손상시키고, 인근 제어선의 전자유도장해를 유발시키게 된다.As shown in FIG. 1, the disconnector used in the conventional gas insulated switchgear is provided with a movable contactor 6 and a fixed contactor 5 having a simple structure in the enclosure 1a to open and close the disconnector of the gas insulated switchgear. When it is opened and closed, the charging charges of the line and bus are cut off. At this time, excessive overvoltage of the steep waveform occurs during the opening and closing, which destroys the enclosure insulation terminal and insulation of the gas insulated switchgear and damages the equipment, and causes electromagnetic induction of nearby control lines. do.
특히, 제어선의 전자유도장해는 보호기기의 오동작을 발생시켜서 전력계통의 신뢰성을 저하시키므로 인해 각종 문제와 사고를 일으킬 우려가 있을 뿐만 아니라, 운전자의 안전사고도 유발시키게 되는 등의 많은 문제점이 있었다.In particular, the electromagnetic induction of the control line causes a malfunction of the protective device, thereby lowering the reliability of the power system, thereby causing various problems and accidents, as well as causing a driver's safety accident.
본 고안은 상기한 제반 문제점을 해결하기 위한 것으로서, 가스절연 개폐장치의 단로기를 개폐시 발생되는 급준파형의 개폐과전압을 단순한 구조로서 현저하게 억제시킬 수 있도록 하여 기기의 오동작과 손상 및 운전자의 안전사고를 미연에 방지할 수 있는 가스절연 개폐장치용 단로기를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and it is possible to significantly suppress the surge voltage of the steep waveform generated when opening and closing the disconnecting device of the gas insulated switchgear as a simple structure, the malfunction and damage of the device and the driver's safety accident It is an object of the present invention to provide a gas insulated switchgear that can be prevented in advance.
상기한 목적을 달성하기 위해 본 고안은 외함에 설치된 도체에 개폐과전압을 억제시키기 위한 저항접촉자를 갖는 저항체가 설치된 가스절연 개폐장치용 단로기이다.In order to achieve the above object, the present invention is a disconnector for a gas insulated switchgear is provided with a resistor having a resistance contact for suppressing the opening and closing overvoltage in the conductor installed in the enclosure.
이하, 본 고안의 일실시예를 첨부도면 제 2 도 및 제 3 도를 참조하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 2 and 3 of the accompanying drawings.
제 2 도는 본 고안을 나타낸 종단면도이고, 제 3 도는 제 2 도의 A-A선 단면도로서, 가스절연 개폐장치용 단로기의 외함(1) 내부에 설치된 도체(2) 내에 개폐과전압을 억제시키기 위한 저항접촉자(3)를 갖는 저항체(4)가 설치되고, 상기 저항접촉자(3)가 단로기의 폐로(투입)동작시에는 고정접촉자(5)보다 선행하여 가동접촉자(6)와 접촉하여 개폐과전압의 크기를 낮추며, 개로동작시에는 가동접촉자(6)가 고정접촉자(5) 보다 저항접촉자(3)를 약8초정도 늦게 개로시켜 개폐과전압을 낮추게 된다.2 is a longitudinal cross-sectional view of the present invention, and FIG. 3 is a cross-sectional view taken along line AA of FIG. 2, and includes a resistance contact for suppressing an open / close overvoltage in a conductor 2 provided inside an enclosure 1 of a gas insulated switchgear. A resistor 4 having 3) is provided, and when the resistance contactor 3 is closed (injection) of the disconnecting device, the contactor 6 is brought in contact with the movable contactor 6 in advance of the fixed contactor 5 to reduce the size of the opening and closing overvoltage. In the opening operation, the movable contactor 6 opens the resistance contactor 3 about 8 seconds later than the fixed contactor 5 to lower the opening and closing overvoltage.
또한, 도체(2)의 내부와 저항체(4) 끝단의 사이에는 동작시 충격을 완하시키기 위한 스프링(7)이 설치되고, 상기 도체(2) 내부의 저항체(4) 일단에는 원활한 습동을 위한 슬라이딩용 판베어링(8)이 삽입되어 구성된다.In addition, a spring 7 is provided between the inside of the conductor 2 and the end of the resistor 4 to alleviate the shock during operation, and the one end of the resistor 4 inside the conductor 2 slides for smooth sliding. The plate bearing 8 for insertion is inserted and comprised.
이와 같이 구성된 본 고안은 제 2 도 및 제 3 도에 나타낸 바와 같이, 가스절연 개폐장치용 단로기의 폐로(투입) 동작시에는 단로기의 조작장치가 구동하면, 외함(1)상의 조작연결부(9)와 이에 연결된 외함(1) 내의 조작봉(10)이 움직여서 가동접촉자(6)를 투입방향으로 이동시킴과 동시에, 이동된 가동접촉자(6) 상기 외함(1) 내부의 도체(2)내에 설치된 저항체(4)의 저항접촉자(3)와 먼저 접촉하고, 약 8초후에 고정접촉자(5)에 접촉하여 단로기는 완전히 폐로된다.The present invention configured as described above, as shown in FIG. 2 and FIG. 3, when the operation device of the disconnector is driven during the closing operation of the disconnecting device for the gas insulated switchgear, the operation connecting portion 9 on the enclosure 1 And the operating rod 10 in the enclosure 1 connected thereto to move the movable contactor 6 in the input direction and simultaneously move the movable contactor 6 in the resistor 2 provided in the conductor 2 inside the enclosure 1. The contactor (3) of (4) is first contacted, and after about 8 seconds, the contactor (5) is contacted and the disconnector is completely closed.
이때, 저항접촉자(3)에 가동접촉자(6)가 접촉하면, 저항체(4)는 도체(2)의 내부와 저항체(4) 끝단의 사이에 설치된 스프링(7)을 밀고서 이동하게 되고, 충전전하가 상기 저항체(4)에서 열로서 소비되어 그 크기가 현저하게 줄어들게 되며, 충전전하는 가동접촉자(6)를 경유하여 저항접촉자(3)와 저항체(4)를 거쳐 저항체(4)의 일단에 삽입된 판베어링(8)과 도체(2)를 통해서 흘러가게 된다.At this time, when the movable contactor 6 contacts the resistance contactor 3, the resistor 4 moves by pushing the spring 7 provided between the inside of the conductor 2 and the end of the resistor 4. The charge is consumed as heat in the resistor 4 and the size thereof is significantly reduced, and the charge is inserted into one end of the resistor 4 via the resistor contact 3 and the resistor 4 via the movable contact 6. It flows through the plate bearing 8 and the conductor 2 which were made.
또한, 단로기의 개로동작시에는 전술한 바와 같이 가동접촉자(6)를 개로방향으로 이동시킴과 동시에, 가동접촉자(6)가 먼저 고정접촉자(5)와 접촉하고, 약 8초후에 저항접촉자(3)와 접촉하여 단로기는 개로상태가 된다.In the opening operation of the disconnector, as described above, the movable contactor 6 is moved in the open direction, and the movable contactor 6 first contacts the fixed contactor 5, and after about 8 seconds, the resistance contactor 3 ), The disconnector is opened.
이때, 저항접촉자(3)와 고정접촉자(5)간의 8초동안 충전전하는 저항체(4)를 통하여 흐르므로 저항체(4)에서 열로서 전부 발산 소멸된 후 안전하게 충전전하를 차단시키게 된다.At this time, since charge charge flows through the resistor 4 during the 8 seconds between the resistance contact 3 and the fixed contact 5, the charge discharge is safely dissipated and extinguished as heat in the resistor 4.
이상에서와 같이, 본 고안은 가스절연 개폐장치용 단로기의 외함(1) 내부에 설치된 도체(2) 내에 저항접촉자(3)를 갖는 저항체(4)가 설치되므로써, 단로기의 개폐시 발생되는 급준파형의 개폐과전압을 간단한 구조로서 현저하게 억제시켜 기기의 오동작과 손상 및 운전자의 안전사고를 미연에 방지할 수 있으므로 인해 기기의 효율성 및 신뢰성을 대폭 향상시킨 매우 유용한 고안이다.As described above, the present invention is a steep wave form generated when the breaker is opened and closed by installing the resistor 4 having the resistance contactor 3 in the conductor 2 installed inside the enclosure 1 of the gas insulated switchgear. It is a very useful design that greatly improves the efficiency and reliability of the device because it can prevent the malfunction and damage of the device and the safety accident of the driver in advance by suppressing the opening and closing voltage of the device with a simple structure.
