Description
본 고안은 전기선로에 대한 유지보수의 작업을 수행하는 배전공사시 수용가측에는 계속적으로 전원을 공급하면서도 공사구간은 정전상태를 유지토록 하여, 정전으로 인한 수용가의 불편을 해소하고 공사 중 작업자의 안전사고 예방을 동시에 구현할 수 있도록 된 무정전 배선공사에 관한 것으로, 더욱 상세하게는 무정전 배선공사를 수행하기 위한 주요구성부품인 변압기와 상기 변압기를 통해 저압으로 출력되는 전원을 수용가측에 전달하는 단말케이블간의 접속작업을 간편하게 완료할 수 있고, 접속시 실제 접촉되는 구성요소간의 변형발생을 감소시켜 수명연장효과를 구현하며, 접속된 각 구성부품 상호간은 견고한 결합상태를 유지하여 사용안정성을 확보할 수 있도록 한 무정전 배전공사용 변압기와 단말케이블의 저압접속구조에 관한 것이다.The present invention maintains the power failure state while supplying power to the consumer side continuously during the power distribution work performing maintenance work on the electric line, eliminating inconveniences of customers due to the power failure and safety accidents of workers during construction. The present invention relates to an uninterruptible wiring work that can be implemented at the same time. More specifically, a connection between a transformer, which is a main component for carrying out an uninterruptible wiring work, and a terminal cable that delivers power output at a low voltage through the transformer to a consumer side. Work can be completed easily, reducing the occurrence of deformation between the components actually contacted during connection to realize the effect of extending the life, and uninterrupted power to ensure the stability of use by maintaining a firm coupling state between each connected components A low voltage connection structure of a transformer and a terminal cable for a distribution engineer.
통상 현대산업의 에너지원으로서 전기(電氣)는 대표적이라 할 수 있으며, 이러한 전기는 발전과 송,배전을 통해 전선을 매개로 하여 각 수용가로 공급되어지는 바, 상기의 전기가 공급되는 배전선로에 대해서는 안전한 송,배전을 위한 유지 및 보수공사가 필요하게 되고 고장수리 및 시설증대 등의 작업소요도 수시로 발생하게 된다.Normally, electricity is a representative energy source of modern industry. Electricity is supplied to each customer through electric wires through power generation, transmission, and distribution. For this, maintenance and repair works are required for safe transmission and distribution, and work demands such as troubleshooting and facility expansion are often generated.
한편, 상기와 같은 배전선로에 대한 각종 공사의 수행에 있어 안정성을 고려한다면 전기를 완전히 차단한 정전상태에서 작업이 이루어지는 것이 바람직하나, 이러한 공사의 수행을 위해 정전상태를 유지할 경우에는 수용가측의 모든 전기장치 작동이 정지되어 막대한 산업상의 손실을 끼침과 더불어 일상생활의 불편함을 야기하게 됨으로써, 새로운 전기배선공사의 공법이 절실히 요구되고 있는 실정이었다.On the other hand, if the stability is considered in the performance of the various construction of the distribution line as described above, it is preferable that the work is performed in the state of blackout completely cut off the electricity, but in the case of maintaining the blackout state for the performance of such construction As electrical devices were stopped and caused huge industrial losses and inconveniences in daily life, a new electric wiring construction method was urgently needed.
그리하여 상기와 같은 요구에 부응하고자 최근에 들어서는 배전선로에 대한 유지보수작업을 수행할 경우 해당 작업구간을 건전구간으로부터 분리시켜 정전상태를 유지하도록 한 후 필요한 공사를 수행하고, 상기 작업에 의한 정전구간의 전기수용가측에는 건전구간으로부터 분기가설한 케이블을 연결시켜 이를 통해 임시적으로 전력공급이 이루어지도록 하는 일명 가송전공법(바이패스공법)이 상용화되고 있는 바, 이러한 가송전공법에 대해 첨부도면 도 1을 참조하여 설명하면 다음과 같다.Therefore, in order to meet the above demands, when performing maintenance work on a distribution line that has recently entered, it is necessary to separate the work section from the health section so as to maintain the blackout state, and then perform necessary construction work. The electric receiving method of the so-called temporary transmission method (bypass method), which connects the cable installed in the branch from the health section to be temporarily supplied, is commercially available. If described with reference to:
즉, 건전구간으로부터 우회송전로인 바이패스선로를 형성하는 케이블을 가설(假設)하고, 이 케이블은 소정형태를 갖는 변압기 차(TC)에 장착된 변압기(T)와 연결되도록 하여, 상기 변압기(T)의 1차 및 2차측을 거치며 저압으로 감압된 전력을 2차측 단자와 접속되는 단말케이블을 통해 수용가로 공급하도록 되어 있다.That is, a cable is formed to form a bypass line, which is a bypass transmission line, from the sounding section, and the cable is connected to a transformer T mounted on a transformer car TC having a predetermined shape, thereby providing the transformer ( Through the primary and secondary side of T), the low-pressure power is supplied to the customer through the terminal cable connected to the secondary terminal.
이와 같은 가송전공법을 채택할 경우에는, 유지보수작업을 수행하고자 하는 해당 선로구간을 정전상태로 유지하더라도 상기 정전구간의 각 수용가측에는 건전구간으로부터 변압기 및 케이블을 거쳐 우회송전되는 전력이 계속적으로 공급되어 공사구간의 선로연결지역 및 수용가에게 무정전 상태의 안정적인 전력공급이 실현되게 되는 것이다.In the case of adopting the above-mentioned provisional transmission method, even if the corresponding line section to perform maintenance work is kept in a blackout state, each customer side of the blackout section is continuously supplied with power bypassed through the transformer and cable from the power section. As a result, uninterrupted and stable power supply is realized to the line connection area and the consumer of the construction section.
한편, 상기한 가송전공법 중 변압기와 케이블을 상호 연결시키기 위한 수단으로 변압기에는 단자가, 케이블에는 접속부재가 각각 마련되며, 이들간의 접속에 의해 변압기와 케이블은 상호 전기적으로 연결되게 되는 것으로, 이러한 변압기의 단자와 케이블 접속부재의 특성으로서는 접속작업시 조립 및 해체가 용이하여야 하고, 기계적인 접속상태의 정확한 유지와 함께 전기적으로도 완전하여야 하며, 케이블의 포설장력이 걸린 상태에서도 손쉽게 분리되지 않아야 한다.On the other hand, as a means for interconnecting the transformer and the cable in the above-mentioned transmission method, the terminal is provided in the transformer, the connection member is provided in the cable, respectively, the transformer and the cable are electrically connected to each other by the connection between these, The characteristics of the terminal of the transformer and the cable connection member should be easy to assemble and dismantle during the connection work, to be electrically complete with accurate maintenance of the mechanical connection, and not to be easily separated even when the cable tension is applied. .
이와 같은 특성을 감안할 때 종래에는, 극도로 감압된 전압의 전력을 송출하는 변압기 2차측 단자와 수용가를 연결하는 단말케이블접속재를 상호 접속시킴에 있어 나사체결에 의한 결합방식을 채택하고 있으나, 이는 접속을 위한 단자와 단말케이블접속재간의 결합작업이 상당히 불편하고 시간이 많이 걸리는 폐단이 노출되었다.In view of such characteristics, conventionally, a screwing coupling method is adopted in interconnecting a terminal cable connecting member for connecting a secondary terminal of a transformer for transmitting electric power of extremely reduced voltage and a customer, but this is a connection method. The coupling work between the terminal and the terminal cable connection material was exposed to the inconvenience and time-consuming closure.
또한, 작업현장에서의 이물질 및 충격 등에 의해 각 구성부품의 나사부가 오손 또는 훼손되거나 잦은 사용에 의한 마찰로써 변형이 발생될 경우에는 접속작업이 곤란하게 되고, 그 정도가 심한 경우에는 부품자체를 못쓰게 되는 문제점이 발생되었다.In addition, when the thread part of each component is damaged or damaged due to foreign matter or impact on the work site or the deformation occurs due to the friction caused by frequent use, it is difficult to connect the parts. The problem arises.
또한, 작업현장에서의 진동이나 케이블의 포설장력에 의해 단자와 단말케이블접속재를 접속시키고 있는 나사부가 손쉽게 해정되어 변압기와 케이블 상호간이 용이하게 분리됨으로써, 그 사용안정성을 보장할 수 없는 치명적인 문제점이 제기되었다.In addition, due to vibration in the workplace or cable laying tension, the screw part connecting the terminal and the terminal cable connecting material is easily released, and the transformer and the cable are easily separated from each other. It became.
본 고안은 전술한 바와 같은 종래 변압기의 2차측 단자와 단말케이블접속재간의 상호 접속방식에서 드러난 여러 문제점들을 효과적으로 해소하기 위하여 연구 개발된 것으로, 특히 배전선로의 유지보수를 위해 일부 선로구간을 정전상태로 유지할 경우에도 해당 정전구간의 수용가측으로는 건전구간으로부터 우회선로를 인출하여 소정의 변압기 및 이와 연결된 단말케이블을 통해 무정전 상태의 전력을 연속적으로 공급하도록 된 무정전 배전공사에 있어서, 상기 변압기를 통해 극도로 감압된 전력을 송출하는 2차측 단자와 이에 접속되어 저압의 전력을 수용가측에 공급하도록 된 단말케이블접속재 상호간을 끼움결합이라는 단순방식에 의해 손쉽게 접속 및 분리가능토록 하여 접속작업을 간편하게 완료할 수 있고, 변압기 2차측 단자내로 소정의 완충부를 마련하여 접속되는 단말케이블접속재와의 충격에 의한 변형발생을 감소시키는 것으로 각 구성부품의 수명연장효과를 구현하며, 접속된 변압기 2차측 단자와 단말케이블접속재 상호간은 소정의 로크장치에 의해 서로 견고히 결합되도록 하여 케이블의 포설장력이 걸려 있는 상태에서도 안정적인 사용이 이루어질 수 있는 무정전 배전공사용 변압기와 단말케이블의 저압접속구조를 제공하는 것에 그 목적이 있다.The present invention has been researched and developed in order to effectively solve the various problems revealed in the interconnection method between the secondary terminal of the conventional transformer and the terminal cable connecting member as described above, and in particular, some line sections are in a blackout state for maintenance of distribution lines. In the uninterruptible power distribution work in which an outgoing line is drawn from the power section to the customer side of the blackout section so as to continuously supply uninterrupted power through a predetermined transformer and a terminal cable connected thereto. It can be easily connected and disconnected by the simple method of interfitting with the secondary terminal which sends the reduced pressure to the terminal and the terminal cable connecting member which is connected to it to supply the low voltage power to the customer side. In the transformer secondary terminal It is possible to realize the effect of extending the life of each component by reducing the occurrence of deformation due to the impact of the terminal cable connecting member to be connected to the connected terminal cable, and the connected transformer secondary terminal and the terminal cable connecting member are firmly secured to each other by a predetermined locking device. The purpose of the present invention is to provide a low voltage connection structure of an uninterruptible power distribution transformer and a terminal cable that can be used in a stable state even when the cable tension of the cable is applied.

The through hole 152 is formed so as to be shifted to the position spaced apart from the predetermined distance with respect to the position.
한편, 첨부도면 도 3에 도시한 바와 같이 단말케이블접속재(20)의 플러그콘넥터(23) 타단에는 소정의 스프링핀(24)에 의해 고정되는 절연접촉부재(25)를 설치하고, 일 부위에 일정높이로 돌출되도록 로크핀(26)을 삽입설치한다.Meanwhile, as shown in FIG. 3, at the other end of the plug connector 23 of the terminal cable connecting member 20, an insulating contact member 25 fixed by a predetermined spring pin 24 is provided, and a portion thereof is fixed. Insert the lock pin 26 to protrude to the height.
이러한 상태에서 상기 변압기 2차측 단자(10)와 단말케이블접속재(20)간의 접속시 플러그콘넥터(23)의 절연접촉부재(25)는 소켓콘넥터(12)의 완충부(13)를 가압하며 이와 접촉되어 있도록 하고, 로크핀(26)은 로크부(15)에 걸려져 변압기 2차측 단자(10)와 단말케이블접속재(20) 상호간을 서로 구속시키도록 함과 동시에, 접점부재(14)와 플러그콘넥터(23)는 상호 접촉되어 있도록 하여 구성된 것이다.In this state, the insulating contact member 25 of the plug connector 23 presses the buffer part 13 of the socket connector 12 and contacts the transformer secondary terminal 10 and the terminal cable connecting member 20. The lock pin 26 is locked to the lock part 15 to restrain the transformer secondary terminal 10 and the terminal cable connecting member 20 from each other, and at the same time, the contact member 14 and the plug connector. 23 is configured to be in contact with each other.
도면 중 미설명 부호로써 16과 27은 각각 변압기 2차측 단자(10)와 단말케이블접속재(20)의 미접속시 소켓콘넥터(12) 및 플러그콘넥터(23)를 보호하도록 된 마감부재를, 17은 패킹을 나타낸 것이다.In the drawings, reference numerals 16 and 27 denote finishing members for protecting the socket connector 12 and the plug connector 23 when the transformer secondary terminal 10 and the terminal cable connecting member 20 are not connected, respectively. The packing is shown.
이와 같은 구성으로 이루어지는 본 고안은 기 언급한 바와 같이 배전선로에 작업소요가 발생될 경우 해당 공사구간을 정전상태로 하고, 정전구간의 수용가측에는 건전구간으로부터 우회선로를 인출하여 이를 통해 무정전 상태에서 안정적으로 전력을 공급시키는 가송전공법에 적용되는 것으로, 다른 구성부품들의 설치관계는 생략하고 본 고안과 관련된 변압기 2차측 단자(10)와 단말케이블접속재(20)간의 결합관계를 살펴보면 다음과 같다.According to the present invention having the above configuration, when work demands on the distribution line occur, the construction section is in a blackout state, and a bypass line is drawn from the health section at the customer side of the blackout section, thereby making it stable in an uninterrupted state. Applied to the method of supplying electric power to the power supply, the coupling relationship between the transformer secondary terminal 10 and the terminal cable connection member 20 related to the present invention is omitted as follows.
변압기 2차측 단자(10)의 소켓콘넥터(12)는 변압기(T)의 2차측 송출부상에 고정설치되고, 단말케이블접속재(20)의 플러그콘넥터(23)에는 수용가측과 연결되는 케이블(C)이 고정설치된 상태에서, 상기 변압기(T)를 통해 감압된 저압의 전력을 수용가측에 무정전 상태로 공급하기 위한 접속작업을 수행하는 경우, 단말케이블접속재(20)의 플러그콘넥터(23) 일측에 일정높이로 돌출되어 있는 로프킨(26)을 변압기 2차측 단자(10)의 소켓콘넥터(12) 끝단에 형성된 절개홈(151) 형성위치와 상호 일치시킨 후 단말케이블접속재(20)를 밀어주면, 로크핀(26)은 절개홈(151)을 통과하게 되고 이로 인해 플러그콘넥(23)가 소켓콘넥터(12)의 내부로 위치되게 된다.The socket connector 12 of the transformer secondary terminal 10 is fixedly installed on the secondary transmission part of the transformer T, and the cable C connected to the consumer side is connected to the plug connector 23 of the terminal cable connecting member 20. In the fixed installation state, when performing a connection operation for supplying the low-pressure power decompressed through the transformer (T) in an uninterruptible state to the consumer side, a constant on one side of the plug connector 23 of the terminal cable connecting member (20) Ropekin (26) protruding at a height coincides with the position of the cutout groove (151) formed at the end of the socket connector (12) of the transformer secondary terminal (10) and then pushes the terminal cable connecting member (20), The pin 26 passes through the incision groove 151, which causes the plug connector 23 to be positioned inside the socket connector 12.
이때, 상기와 같은 동작과정에서 플러그콘넥터(23)의 끝단에 고정설치되어 있는 절연접촉부재(25)는 완충부(13)를 이루는 이송핀(132)을 밀어주게 되고, 이러한 밀림동작에 의해 위치고정나사(133) 내에서 후진동작되어 완충스프링(131)을 압축시키게 된다.At this time, the insulating contact member 25 fixed to the end of the plug connector 23 in the operation process as described above is to push the transfer pin 132 constituting the buffer portion 13, the position by this push operation The reverse operation is performed in the fixing screw 133 to compress the shock absorbing spring 131.
이와 같은 완충스프링(131)의 압축에 의해 플러그콘넥터(23)의 삽입시 발생되는 마찰충격은 흡수되어져 소켓콘넥터(12) 및 플러그콘넥터(23)의 각 접촉부위에 대한 변형 발생빈도를 감소시킴으로써, 그들 구성부품의 수명을 연장시키게 된다.By compressing the shock absorbing spring 131, the frictional shock generated when the plug connector 23 is inserted is absorbed to reduce the frequency of deformation of each contacting portion of the socket connector 12 and the plug connector 23, Extend the life of their components.
