원격송전 가공전선의 고정용 절연애자{Remote Power Cable With Insulator For Fixing}Insulation Insulator for Remote Transmission Process Wire {Remote Power Cable With Insulator For Fixing}

본 발명은, 완철에 설치되어 송전선을 안정적으로 고정함과 동시에 애자가 손상된 경우 신속하고 용이하게 교체할 수 있도록 된 원격송전 가공전선의 고정용 절연애자에 관한 것이다.The present invention relates to an insulator for fixing a remote transmission overhead wire, which is installed on a wrought iron so that the transmission line can be stably fixed and the insulator can be replaced quickly and easily.

일반적으로 전기의 효율을 높이기 위하여 발전소는 송전압을 높게 하여 전송한다. In general, in order to increase the efficiency of electricity, power plants transmit with a high transmission voltage.

하지만, 이러한 고압의 전기는 실생활에 직접 적용하기가 어려워 통상 주상변압기를 통해 감압시켜 가정으로 전송하며, 공장 등과 같이 고압의 전류를 요구하는 경우에는 주상변압기 대신 자가 변전실을 별도로 운영하는 것이 일반적이다.However, such high-voltage electricity is difficult to be applied directly to real life, so it is usually reduced by a columnar transformer and transmitted to the home, and when a high-voltage current is required, such as a factory, it is common to operate a separate substation chamber instead of a columnar transformer.

발전소에서 송전압을 높게 하여 전송할 때에 고압의 전류가 흐르는 전선을 안내할 수 있도록 전주를 사용하게 되는데, 통상의 전주에는 고압의 전류를 안전하게 흘려보내고자 완철에 라인포스트애자(LP Insulator)라고 통상 지칭되는 애자를 구비하여 애자 위에 고압의 전선을 고정시켜 줌으로서, 송전선의 고압전류가 완철 과 접촉되는 것을 차단한다.Electric poles are used to guide high-current wires during transmission at higher power transmission voltages in power plants. In general, poles are called line insulators (LP insulators) in order to safely flow high voltage currents. It is provided with an insulator to fix the high voltage wire on the insulator, thereby preventing the high voltage current of the transmission line from contacting the complete iron.

상기 애자의 경우 일반적으로 상면으로 송전선이 안착되고, 안착된 송전선과 애자의 상부를 합성수지재가 피복된 감김부재를 이용하여 감아 줌으로서, 송전선이 외부로 이탈되는 것을 방지토록 한다. In the case of the insulator, a transmission line is generally seated on an upper surface of the insulator, and the upper part of the insulated transmission line and the insulator are wound by using a winding member coated with a synthetic resin material, thereby preventing the transmission line from escaping to the outside.

하지만, 상기 애자가 주간이 아닌 야간에 손상되어 작업자가 교체작업을 위해 전주에 올라가는 경우 교체장비 이외에 별도의 조명수단을 구비하여 올라가야 하므로, 교체작업에 따른 작업효율이 떨어지는 문제가 있고, 뿐만 아니라, 일단 애자를 교체하기 위해서는 송전선으로의 전력 흐름을 차단한 상태에서 송전선과 애자를 감고 있는 감김부재를 풀어 해제하고, 감김부재를 완전히 해제시켜 준 상태에서 새로운 애자로 교체하며, 교체한 이후에 상기와 같은 방법으로 재차 감아 고정해야하는 일련의 교체과정이 상당히 복잡하고 교체시간이 오래 소요되는 문제가 있으며, 이로 인하여 애자를 교체하는 과정에 전력이 차단되어 있어 사용자들이 전력사용을 할 수 없게 되는 문제가 있다..However, if the insulator is damaged at night instead of daytime, when the worker climbs up to Jeonju for replacement work, it must be equipped with a separate lighting means in addition to the replacement equipment, thereby reducing the work efficiency due to the replacement work. In order to replace the insulator, the coil and the insulator are wound around the transmission line and the insulator in the state that the power flow to the power line is cut off, and the insulator is completely released and replaced with a new insulator. As a result, a series of replacement processes that need to be wound again and fixed again are quite complicated and take a long time to replace. As a result, power is cut off in the process of replacing insulators, which prevents users from using power. have..

또한, 상기 애자를 교체하는 과정에 작업자 상호 간에 의사전달이 잘못되어 전력이 차단된 송전선에 전력을 공급하는 경우 자칫 작업자가 감전사하는 경우가 빈번히 발생하고 있는 바, 신속하고 안전하게 교체할 수 있는 그 대안에 대한 연구가 활발히 진행 중이다.In addition, when power is supplied to a power line in which power is cut off due to communication between the workers in the process of replacing the insulator, the worker frequently becomes electrocuted. Therefore, the alternative that can be replaced quickly and safely Research is actively underway.

본 발명은 상기와 같은 문제를 해소하고자 안출된 것으로서, 무선조작방식을 통해 작업자가 직접 송전선을 만질 필요가 없기 때문에 감전에 의한 전기안전사고로부터 작업자를 보호함과 동시에 작업의 편의성을 도모할 수 있고, 교체작업에 따른 시간을 줄일 수 있어 송전선의 전력 차단으로 인해 전력사용을 할 수 없었던 사용자들이 불편함을 원천적으로 해소할 수 있는 원격송전 가공전선의 고정용 절연애자를 제공하려는데 그 목적이 있다.The present invention has been made to solve the above problems, because the operator does not need to touch the power line directly through the wireless operation method can protect the operator from electrical safety accidents due to electric shock and at the same time can facilitate the operation.

위와 같은 구성으로 이루어진 본 발명의 작동관계를 설명하면 다음과 같다.Referring to the operational relationship of the present invention made of the above configuration as follows.

도 5a 내지 도 5c는 본 발명에 따른 원격송전 가공전선의 고정용 절연애자의 작동관계를 보인 사용상태도이다.5a to 5c is a state diagram showing the operation relationship of the fixing insulator of the remote transmission overhead wire in accordance with the present invention.

도 5a 내지 도 5b에 도시된 바와 같이 외력 또는 노후로 의해 절연부재(40)가 손상되어 그 기능을 상실하게 되면, 작업자는 휴대하고 있던 리모콘부(200)을 조작하여 절연부재(40)에 교체작업을 진행하게 된다.5A to 5B, when the insulating member 40 is damaged by external force or aging and loses its function, the operator operates the remote controller 200 that is being carried and replaces it with the insulating member 40. You will be working.

상기 교체작업을 상세히 설명하면, 전주(P)를 타고 올라간 상태에서 리모콘부(200)의 조작버튼(210)을 눌러주게 되면, 조작버튼(210)에 의해 신호가 출력되고, 출력된 신호는 제2제어부(220)로 전달되어 동작신호를 출력하여 송신부(230)로 전달하며, 동작신호를 전달받은 송신부(230)는 완철(10)의 커버(12)에 형성된 수신부(100)로 동작신호를 무선송출하게 된다.When the replacement operation is described in detail, when pressing the operation button 210 of the remote control unit 200 in the state of riding up the pole (P), the signal is output by the operation button 210, the output signal is the first 2 is transmitted to the control unit 220 and outputs the operation signal to the transmission unit 230, the transmission unit 230 receiving the operation signal to the receiving unit 100 formed on the cover 12 of the sturdy 10 to the operation signal Radio transmission.

따라서, 무선송출에 의해 동작신호를 수신받은 수신부(100)는 동작신호를 제1제어부(110)로 전달하고, 동작신호를 전달받은 제1제어부(110)는 구동모터(20)와 램프(70)의 동작을 각각 제어하게 되는데, 이때 반 시계방향으로 회전되는 구동모터(20)에 의해 회전드럼(30)이 함께 회전되고, 회전드럼(30)에 고정되어 있던 절연부재(40) 역시 함께 회전한다.Accordingly, the receiver 100 receiving the operation signal by wireless transmission transmits the operation signal to the first control unit 110, and the first control unit 110 receiving the operation signal transmits the driving motor 20 and the lamp 70. ) To control the operation of each, wherein the rotating drum 30 is rotated together by the drive motor 20 which is rotated counterclockwise, and the insulating member 40 fixed to the rotating drum 30 is also rotated together. do.

상기와 같이 송전선(L)을 억류하고 있던 절연부재(40)는 반 시계방향으로 회전되면서 고정부(41)에서 송전선(L)이 서서히 이탈되고, 절연부재(40)가 완전히 회전되어 9시방향에 위치되면 고정부(41)에서 완전히 이탈되어 송전선(L)은 자중에 의해 낙하 되는데, 이때 절연부재(40)에 의해 상호 이격상태를 유지하고 있던 한 쌍의 송전선지지편(61)은 탄지편(62)의 탄발력에 의해 임의간격을 이루며 원상회복하기 때문에 송전선(L)이 낙하 되더라도 안전하게 받쳐 지지할 수 있게 되는 것이이며, 이를 도 5c와 같이 도시하였다.As described above, the insulating member 40 holding the transmission line L is rotated counterclockwise while the transmission line L is gradually released from the fixing part 41, and the insulating member 40 is completely rotated at 9 o'clock. If it is located in the fixed portion 41 is completely separated from the power transmission line (L) is dropped by its own weight, at this time, the pair of power transmission line support pieces 61 that were kept apart from each other by the insulating member 40 is a tangy piece Due to the resilient force of (62), it is possible to safely support the support line even if the power line (L) falls because it recovers the original shape at random intervals, as shown in FIG. 5C.

상기 새 절연부재(40)를 회전드럼(30)에 장착시켜 준 이후에는 작업자가 휴대하고 있는 리모콘부(200)를 재차 조작하면, 구동모터(20)에 의해 회전드럼(30)이 시계방향으로 회전하게 되고, 이때 회전드럼(30)에 장착된 새 절연부재(40) 역시 함께 회전되면서, 송전선지지편(61)에 안착되어 있던 송전선(L)에 결합되면서 송전선(L)을 억류하게 된다.After the new insulating member 40 is mounted on the rotating drum 30, when the operator operates the remote controller 200 again, the rotating drum 30 is rotated clockwise by the driving motor 20. At this time, the new insulating member 40 mounted on the rotating drum 30 is also rotated together, while being coupled to the transmission line L seated on the transmission line support piece 61, the transmission line L is detained.

이를 좀 더 상세히 설명하면, 둘레면에 새 절연부재(40)가 설치된 회전드럼(30)이 구동모터(20)에 의해 회동되면, 새 절연부재(40)의 상부 단봉(구체적으로 도시하지 아니함)이 송전선지지편(61)의 하부 가이드편(구체적으로 도시하지 아니함) 사이로 삽입되면서 간격이 점진적으로 이격되고, 이때 송전선지지편(61)에 안착되어 있던 송전선(L)은 축 중심으로 회전되는 고정부(41)로 자중과 밀고 들어가려는 힘에 의해 자연스럽게 삽입되어 억류되게 되어, 도 5a와 같은 상태를 유지하게 되는 것이다. In more detail, when the rotating drum 30 in which the new insulation member 40 is installed on the circumferential surface is rotated by the driving motor 20, the upper end of the new insulation member 40 (not specifically shown). The gap is gradually spaced apart while being inserted between the lower guide pieces (not specifically shown) of the transmission line support piece 61, and the transmission line L seated on the transmission line support piece 61 is rotated about an axis. Naturally inserted and detained by the weight and the force to push into the government 41, it will be maintained as shown in Figure 5a.

이와 같이, 작업자가 리모콘부(200)를 통해 구동모터(20)와 램프(70)를 각각 통제할 수 있도록 하여 절연부재(40)의 손상 또는 노후인한 교체작업시 절연부재(40)와 일정 거리를 유지한 상태에서도 교체작업이 가능하므로 작업효율성 및 편의성이 향상되며, 나아가 종래와 같이 작업자가 수작업으로 절연부재(40)를 교체할 필요가 없기 때문에 전기안전사고를 미연에 방지할 수 있어 작업자에 안전성을 확보할 수 있게 되는 것이다.As such, the operator can control the driving motor 20 and the lamp 70 through the remote control unit 200, respectively, and a predetermined distance from the insulating member 40 during replacement or damage of the insulating member 40. The replacement work is possible even in the state of maintaining the efficiency and convenience, and furthermore, since the operator does not need to replace the insulating member 40 by hand as in the prior art, an electrical safety accident can be prevented in advance. It will be able to secure safety.
