One end of the pair of band-shaped conductors 10A and 10B is inserted into the receiving groove 13A of the bus bar support 13, and the other end of the band-like conductors 10A and 10B is installed at a location that does not correspond to the insulator 12. The fixing bolt 16 inserted in the hole 15 and inserted from the hole of the mounting hardware 15 passes between the band-like conductors and the bus bar support 13, and the band-shaped conductor is fixed to the fixing bolt 16 protruding from the back of the bus bar support. Tighten and fix the nut (17). When the busbar support 13 is not used, the band-shaped conductor 70 may be fixed between the mounting hardware 15 as shown in FIG. 5, but in this case, the mounting hardware 15 and the other conductor 15A The incisal hardware 15 is formed in the dimension X which can take an insulation distance.
설치나사(18)는 제6도와 같이 한쌍의 띠상 도체사이에 삽입하고, 선단의 걸침부 (18A)를 모선지지대(13)과 대응하지 않는 한쪽의 띠상 도체 예를 들면 띠상도체 (10B)의 배면에 걸고, 타단측을 절연대(12)의 제2설치면(12D)의 나사구멍(12F)에 삽입하고, 설치나사(18)에 너트(19)를 삽입하여 조임으로써 절연대(12)를 띠상도체(10) 즉 전원측 모선에 지지한다.The mounting screw 18 is inserted between the pair of band-like conductors as shown in FIG. 6, and the rear end portion of the band-shaped conductor, for example, the band-shaped conductor 10B, does not correspond to the bus bar support 13A. The other end side is inserted into the screw hole 12F of the second mounting surface 12D of the insulator 12, and the nut 19 is inserted into the mounting screw 18 and tightened. It is supported by the strip | belt-shaped conductor 10, ie, a power supply side bus bar.
이 상태에서 전원측 도체(7)의 접촉부(7C)는 관통구멍(12A)과 띠상도체 사이에 삽입하고, 접촉부(7C)를 띠상도체(10A, 10B)에 접촉한다. 중간부(9B)는 가로홈부내에 배치되고, 선단부(9A)를 배선용 차단기(4)의 개구부(4B)에 삽입하고, 선단부(9A)의 나사구멍과 전원측 단자(4B)의 나사구멍을 관통한 나사(20)에 의하여 양자를 고정한다. 배선용 차단기(4)는 나사구멍(4C)으로부터 삽입한 나사(21)를 제1설치면(12C)의 나사구멍에 틀어 넣어 고정한다.In this state, the contact portion 7C of the power supply-side conductor 7 is inserted between the through-hole 12A and the strip-shaped conductor, and the contact portion 7C contacts the strip-shaped conductors 10A and 10B. The intermediate portion 9B is disposed in the horizontal groove portion, inserts the tip portion 9A into the opening portion 4B of the wiring breaker 4, and passes through the screw hole of the tip portion 9A and the screw hole of the power supply terminal 4B. Both screws are fixed by one screw 20. The wiring breaker 4 fixes the screw 21 inserted from the screw hole 4C by screwing it into the screw hole of the first mounting surface 12C.
따라서, 배선용 차단기(4)의 부하용량이 변하여, 배선용 차단기(4)를 교환하는 경우에는, 나사(21)를 빼면, 배선용차단기(4)는 곧장 절연대(12)로부터 제거되거나, 또는 설치하거나 할 수가 있으므로 교환작업이 용이하게 되었다.Therefore, when the load capacity of the wiring breaker 4 changes and the wiring breaker 4 is replaced, when the screw 21 is removed, the wiring breaker 4 is immediately removed from the insulating stand 12 or installed. This makes it easier to replace.
또, 설치나사(18)의 너트(19)를 회전하면, 전원측모선(70)을 모선지지대(13)와 절연대(12)로부터 설치(부착)하거나, 빼내거나(떼어내거나) 하는 일이 용이하게 된다. 또, 전원측모선(10)에 배선용 차단기(4)와 걸연대(12)등을 집중시켰으므로, 조립분해 작업이 용이해겼을 뿐만아니라, 또 설치나사(18), 설치철물(15)등의 종류를 현저하게 적게할 수 있게 되었다. 또, 부하측 분기도체(7)와 전원측 모선(10)의 일단이 인접되어 있어, 양자를 접속할 때에 최단거리로 접속할 수 있으므로 경제적이다.In addition, when the nut 19 of the mounting screw 18 is rotated, it is easy to install (attach), pull out (remove) the power supply side busbar 70 from the busbar support 13 and the insulator 12. Done. In addition, since the circuit breaker 4, the hooking rod 12, etc. were concentrated on the power supply side bus line 10, the assembly and disassembly work was made easier, and the mounting screws 18, the mounting hardware 15, etc. It became possible to considerably reduce kinds. In addition, one end of the load-side branch conductor 7 and the power supply-side busbar 10 is adjacent to each other, so that the connection can be made in the shortest distance when the both are connected.
또, 고정볼트(17), 설치나사(18,18A), 나사(21), 너트(17)등의 전원측 모선(10)에 접촉하는 부분을 절연부재에 의하여 피복하거나, 또는 설치나사(18), 나사(21)의 정면측 부분 즉 작업원이 접촉하는 측을 절연부재에 의하여 피복하거나 하므로서, 배선용 차단기(4)를 전원측모선(10)에 설치하거나, 제거하거나 할 때의 감전을 방지하고 있다. 또, 나사, 너트를 절연부재로 구성해도 좋다.In addition, a portion of the fixing bolt 17, the mounting screws 18, 18A, the screw 21, the nut 17, and the like that contacts the power supply side busbar 10 may be covered with an insulating member, or the mounting screw 18 may be used. By covering the front side portion of the screw 21, that is, the side where the worker contacts, with an insulating member, an electric shock when the wiring breaker 4 is installed or removed from the power supply side bus line 10 is prevented. . Moreover, you may comprise a screw and a nut with an insulating member.
