공동주택용 전선의 배선안내 절연관{Insulation Tube For Wiring Guide Of Apartment House}Insulation Tube For Wiring Guide Of Apartment House

본 발명은 공동주택용 전선의 배선안내 절연관에 관한 것이다.
The present invention relates to a wiring guide insulated tube of a wire for apartment house.

일반적으로 각 가정이나 사무실 및 대규모의 공장 등에서 사용되는 전기는 각 지역별로 설비되어 있는 변전소를 통해 전기를 공급받게 되는데, 이러한 변전소는 전압이나 전류의 변성 및 전력의 배분을 목적으로 설치된다.In general, the electricity used in each home or office and a large-scale factory is supplied with electricity through substations installed in each region. Such substations are installed for the purpose of changing voltage or current and distributing power.

상기 변전소에서 상용전력으로 변환된 전력선은 통상 아파트의 각 가정으로 전원을 분기시키는 분전반에 연결되는데, 이 경우 단순히 전력선을 외력으로부터 보호하기 위하여 파이프를 분전반까지 연장하고 그 파이프의 내측으로 전력선을 삽입한 상태에서 분전반 내부에 설치된 차단기에 설치된다.The power line converted from the substation into commercial power is usually connected to a distribution board for branching power to each home in the apartment. It is installed in the breaker installed inside the distribution panel.

하지만, 이와 같이 설치된 전력선의 경우 과전류 또는 노후로 인해 전력선에 화재에 휩싸이는 경우 전력선의 피복을 따라 화재가 신속하게 번져 전부 전소되기 쉽고, 전소된 전력선의 경우 재차 시공해야하므로, 비용 및 시간 과다하게 소요되며, 이로 인해 각 가정의 전력사용자는 시공기간에는 전력을 사용할 수 없는 문제가 발생되는 바, 이를 해소하기 위한 연구가 활발히 진행 중이였다.
However, in the case of a power line installed in this way, if a fire is caught in the power line due to overcurrent or aging, the fire spreads quickly along the covering of the power line, and it is easy to burn all the burned power lines. As a result, power users in each household are not able to use the power during the construction period. Therefore, studies to solve this problem were actively conducted.

본 발명은 상기와 같은 문제를 해소하기 위하여 안출된 것으로서, 차폐제가 충진된 배선관체의 내부에 전선이 삽입되어 보호되므로, 화재가 발생하더라도 차폐제에 의해 전선이 전부 전소되는 것을 방지할 수 있도록 된 공동주택용 전선의 배선안내 절연관을 제공하려는데 그 목적이 있다.
The present invention has been made in order to solve the above problems, and since the wire is inserted and protected inside the wiring pipe filled with the shielding agent, even if a fire occurs, it is possible to prevent the entire wire burned out by the shielding agent. The purpose is to provide wiring guidance insulators for residential electrical wires.

상기 목적을 달성하기 위한 본 발명은, The present invention for achieving the above object,

벽체에 매설되되, 내주면에 나사부가 형성된 말단부가 배전함의 수용부로 노출되고, 내측으로 전선이 삽입되는 매립관부와;A buried pipe portion embedded in a wall, the end portion having a screw portion on an inner circumferential surface thereof being exposed to a receiving portion of a distribution box, and an electric wire inserted into the inner portion;

둘레면에 나사부를 갖추고서, 매립관부의 나사부에 체결되는 전선인입부와, 전선인입부의 말단에서 연장되며 전체적으로‘U’자 형상을 이루는 만곡부와, 만곡부의 말단에서 수평하게 연장되는 전선인출부로 구성된 전선안내관부를 갖춘 배선관체와:It has a threaded part on the circumferential surface, and consists of a wire lead-in which is fastened to the screw of the buried pipe, a curved portion extending from the end of the wire lead-in and forming a 'U' shape as a whole, and a wire lead-out extending horizontally from the end of the curved portion. Wiring conduit with wire guide tube:

전선안내관부의 만곡부에 수용되어 전선안내관부의 내측으로 인입된 전선을 매설하는 차폐제를 포함하는 것을 특징으로 한다.
It is characterized in that it comprises a shielding agent which is accommodated in the curved portion of the wire guide pipe portion embedded the wire drawn into the wire guide pipe portion.

상기와 같은 구성으로 이루어진 본 발명은, 전선안내관부의 내부에 차폐제를 충진하고 차폐제에 의해 실외전선 또는 실내전선의 일부가 매설되도록 하므로서, 과전류 또는 노후로 인해 화재가 발생되어 실외전선 또는 실내전선의 피복을 타고 불길이 번지더라도 내부에 충진된 차폐제에 의해 불길이 저지되기 때문에, 실외전선 또는 실내전선이 화재에 의해 전부 전소되는 것을 최소화할 수 있다.
According to the present invention having the above configuration, the shielding agent is filled in the inside of the electric wire guide tube portion and the outdoor wire or the indoor wire is partially embedded by the shielding agent. Even if the fire spreads through the coating, since the flame is blocked by the shielding agent filled therein, it is possible to minimize the burning of all the outdoor or indoor wires by the fire.

L1) or indoor wire (L2) can be minimized to completely burn out by the fire.

이와 같은 구성으로 이루어진 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention made of such a configuration as follows.

우선, 도 1 내지 도 2에 도시된 바와 같이 벽체(1)에 힌지를 매개로 개폐가능하게 설치된 도어부(2-1)를 갖춘 배전함(2)을 설치하고, 배전함(2)의 내부에 체결부재를 매개로 장착판(3)을 설치하며, 장착판(3)에는 메인차단기(4)와 다수개의 보조차단기(5)를 체결부재를 매개로 고정해 준다.First, as shown in FIGS. 1 and 2, a distribution box 2 having a door part 2-1 installed on the wall 1 to be opened and closed via a hinge is installed and fastened inside the distribution box 2. The mounting plate 3 is installed through the member, and the mounting plate 3 fixes the main circuit breaker 4 and the plurality of auxiliary circuit breakers 5 through the fastening member.

특히, 상기 배전함(2)을 설치해 줄 때에 외부로 노출된 매립관부(11)의 말단부가 배전함(2)의 내측에 배치되도록 설치하는 것이 바람직하다.In particular, when the distribution box 2 is installed, it is preferable that the distal end of the buried pipe part 11 exposed to the outside is disposed so as to be disposed inside the distribution box 2.

상기와 같이 배전함(2)을 설치한 상태에서 매립관부(11)에 내설된 실외전선(L1) 또는 실내전선(L2)을 배전함(2)으로 노출시켜 주고, 노출된 실외전선(L1) 또는 실내전선(L2)을 전선안내관부(12)에 삽입하여 관통되도록 한 다음 전선안내관부(12) 전선인입부(12a)를 매립관부(11)의 내주면을 향해 체결하여 고정한다.In the state in which the distribution box (2) is installed as described above to expose the outdoor wire (L1) or indoor wire (L2) in the buried pipe section 11 to the distribution box (2), exposed outdoor wire (L1) or indoor Insert the electric wire (L2) into the wire guide tube portion 12 so as to penetrate and then fasten the wire guide tube portion 12 wire lead portion (12a) toward the inner circumferential surface of the buried pipe portion (11).

특히, 상기 전선안내관부(12)를 매립관부(11)에 체결시켜 줄 때에 만곡부(12b)가 하방향을 향하도록 설치해 줌으로서, 만곡부(12b)에 충진된 차폐제(20)가 외부로 인출되지 않도록 하는 것이 바람직하다. In particular, when the wire guide tube portion 12 is fastened to the buried tube portion 11, the curved portion 12b is installed downward, so that the shielding agent 20 filled in the curved portion 12b is not drawn out. It is desirable to avoid.

만약, 작업중 실수로 만곡부(12b)에 충진된 차폐제(20)가 외부로 인출되었을 경우에는 차폐제(20)를 재차 만곡부(12b)에 충진하여 실외전선(L1) 또는 실내전선(L2)의 외면이 매설되도록 하는 것이 바람직하다.If the shielding agent 20 filled in the curved portion 12b is accidentally drawn out during the operation, the shielding agent 20 is filled in the curved portion 12b again to allow the outer surface of the outdoor wire L1 or the indoor wire L2. It is desirable to be buried.

상기와 같이 실외전선(L1) 및 실내전선(L2)을 설치한 상태에서 실외전선(L1)은 메인차단기(4)에 실내전선(L2)은 보조차단기(5)에 설치하면 된다.
In the state where the outdoor wire L1 and the indoor wire L2 are installed as described above, the outdoor wire L1 may be installed in the main circuit breaker 4, and the indoor wire L2 may be installed in the auxiliary circuit breaker 5.

한편, 상기와 같이 설치된 상태에서 실외전선(L1) 또는 실내전선(L2)이 과전류 또는 노후로 인해 화재가 발생할 경우 실외전선(L1) 또는 실내전선(L2)의 피복을 타고 불길이 번지게 되는데, 이때 배선관체(10)의 전선안내관부(12)까지 불길이 인입될 경우 만곡부(12b)의 내부에 충진된 차폐제(20)에 의해 불길이 저지되기 때문에, 실외전선(L1) 또는 실내전선(L2)이 화재에 의해 전부 전소되는 것을 최소화할 수 있으며, 이를 도 4와 같이 도시하였다.
On the other hand, when the fire occurs due to the overcurrent or aging of the outdoor wire (L1) or indoor wire (L2) in the installed state as described above, the flame is spread on the cover of the outdoor wire (L1) or indoor wire (L2), At this time, if the flame is introduced to the wire guide tube portion 12 of the wiring pipe 10, since the flame is blocked by the shielding agent 20 filled in the curved portion 12b, the outdoor wire (L1) or indoor wire (L2) ) Can be completely minimized by the fire, as shown in FIG.
