본 발명은 건축물에 설치되는 전기 시설물인 케이블 트레이에 관한 것으로서, 더욱 상세하게는 전기케이블을 연결구에 의해 연장되는 케이블보호관 내에 삽입하고, 케이블보호관이 지지트레이에 의해 지지되게 하여 설치가 간편하고, 전기케이블을 잘 보호할 수 있는 건축물 전기 케이블 트레이 구조에 관한 것이다.The present invention relates to a cable tray, which is an electrical facility installed in a building, and more particularly, inserts an electric cable into a cable protection tube extending by a connector, and allows the cable protection tube to be supported by a support tray, thereby simplifying installation. The present invention relates to a building electric cable tray structure that can protect cables well.

종래에는 공장, 창고, 공동주택의 지하실이나 주차장 등에 전선을 배선하기 위하여 배선용 애자를 천정 및 벽면에 설치하여 전선을 고정하였으나, 케이블선 배선시에는 애자 이용을 못하므로 파이프나 로-프를 배선방향으로 설치하고, 이에 전선을 묶어서 고정하는 방법으로 전기배선을 함에 따라, 여러개의 전선을 파이프나 로-프에 무질서하게 뒤엉키게 설치하게 되고, 전선의 배선시 절곡부분이 생기므로 화제의 위험성이 있으며, 전선의 취급관리가 어려운 문제점이 있었다.Conventionally, wiring insulators were installed on ceilings and walls in order to wire electric wires in factories, warehouses, basements, parking lots, etc., but the wires were fixed when wiring cables. As the electric wiring is installed by tying and fixing the electric wires, the electric wires are tangled in a disorderly manner in the pipe or the rope. There was a problem that the handling and management of electric wires were difficult.

일반적으로 도심지역의 건물이나 대단위의 아파트단지 또는 공장 등에는 전력선과 통신선 등의 많은 케이블이 설치되는데, 이러한 케이블은 통상 지하공동구 또는 건물의 천정이나 벽체를 따라 배선된다. 이때, 케이블이 자체 하중으로 인하여 아래로 심하게 처질 뿐 아니라 다른 구조물과 간섭되어 손상될 우려가 높고, 미관도 해치게 된다.In general, many cables, such as power lines and communication lines, are installed in buildings, large apartment complexes, or factories in urban areas. Such cables are usually wired along underground ceilings or ceilings or walls of buildings. At this time, the cable is not only drastically droops down due to its own load, but also interferes with other structures, causing high damage, and hurting aesthetics.

이에 따라 케이블은 적절한 구조적 강도를 갖는 금속제의 트레이를 사용하여 받쳐주는 것이 일반적이다. 트레이는 서로 평행하게 세로로 배치된 두 사이드빔(side beam)의 하단부에 케이블을 결속시키기 위한 다수의 렁(rung)에 의해 일정간격으로 연결한 대략 사다리형태의 구성을 가지며, 브래킷(bracket)이나 행거(hanger)에 의해 벽 또는 천정에 수평으로 지지된다.Accordingly, the cable is generally supported by using a metal tray having appropriate structural strength. The tray has a substantially ladder-like configuration connected at regular intervals by a plurality of rungs for binding cables to the lower ends of two side beams arranged in parallel to each other. It is supported horizontally on the wall or ceiling by a hanger.

그리고 위로부터 이물질이나 빗물 등이 낙하되어 케이블이 손상되는 것을 방지하기 위해 트레이의 상부 개구에 덮개를 씌워 케이블을 보호하기도 한다.In order to prevent the cable from being damaged by falling foreign matter or rainwater from above, the cable is covered with an upper opening of the tray to protect the cable.

한편, 전력선과 통신선은 좁은 지역에 전기통신선로와 초고압송 배전선로 및 교류 전기철도선로 등이 양적으로 급증하고 있는 현대의 복잡한 도시구조와 건물의 특성상 경우에 따라 하나의 케이블 트레이에 동시에 지지되거나 또는 상하좌우로 인접하여 배선될 수밖에 없는데, 이 경우 약한 전류가 흐르는 통신선에 강한 전류가 흐르는 전력선에 의한 이상전압 및 전류가 유도되어 통신시설에 노이즈나 누화 등의 각종 장애가 발생되며, 이러한 현상을 소위 '유도장애'라 한다.On the other hand, power lines and communication lines are simultaneously supported by a single cable tray depending on the characteristics of modern complex urban structures and buildings, in which a quantitative increase in telecommunication lines, ultra-high-voltage distribution lines, and alternating current electric railway lines is carried out in a narrow area. There is no choice but to wire up, down, left, and right.In this case, abnormal voltages and currents are induced by power lines flowing strong currents to communication lines flowing weak currents, and various disturbances such as noise or crosstalk occur in communication facilities. Induction disorders'.

이러한 유도장애는 통신시설 뿐 아니라 컴퓨터나 전기·전자기기 등에도 오동작을 유발하고, 심한 경우 절연파괴현상을 일으키기도 하며, 인접한 전기철도의 교류전압에서 방출되는 고조파(harmonics)에 의해서도 발생한다. 특히, 근래 들어 송전선에 초고압의 3상 4선식 Y결선방식을 사용함에 따라 통신선의 유도장애가 더욱 심해지고 있다.These induced disturbances cause malfunctions not only in communication facilities but also in computers, electrical and electronic devices, and in severe cases, insulation breakdown, and are also caused by harmonics emitted from AC voltages of adjacent electric railways. In particular, in recent years, the use of an ultra-high voltage three-phase four-wire Y connection method for the transmission line has become more severe inductive interference of the communication line.

유도장애의 원인에는 정전유도(electrostatic induction)와 전자유도(self inductance)가 있다. 정전유도는 도체(導體) 또는 유전체(誘電體)에 전하(電荷)를 접근시킬 때 전하가 만드는 정전기장의 영향으로 도체 또는 유전체 표면에 전하가 나타나는 현상이며, 이로 인한 정전유도장애는 전압적 접근이 주원인으로 시간적으로 변화하지 않는 높은 유도 전압에 의해 발생되지만 통신선을 도체인 금속으로 피복하여 접지하거나 통신선 근처에 접지된 도체가 있는 경우 거의 차폐(약 90%)될 뿐 아니라 전력선과의 이격거리가 약 50m이상이면 거의 영향을 받지 않는다.The causes of induction disorders are electrostatic induction and self inductance. Electrostatic induction is a phenomenon in which charge appears on the surface of a conductor or dielectric due to the effect of the electrostatic field created by the charge when the charge is approached to a conductor or dielectric. It is caused by a high induced voltage that does not change in time as the main cause, but it is almost shielded (approximately 90%) when the grounded conductor is covered with metal as a conductor or when there is a grounded conductor near the communication line, and the distance from the power line is weak. If it is 50m or more, it is hardly affected.

이에 반해, 전자유도는 전류의 변화와 더불어 자기 자신의 회로를 관통하는 자력선속(磁力線束)이 변화하기 때문에 발생하는 현상이며, 이로 인한 전자유도장애는 전류적 평형이 주원인으로 시간적으로 변화하는 낮은 유도전압에 의해 발생되지만 차폐피복층을 갖는 케이블이나 지중케이블의 경우에도 발생할 뿐 아니라 시간적 변화가 심하며 전력선과의 이격거리가 50m이상일 때도 비교적 심하게 발생한다.On the other hand, electromagnetic induction is a phenomenon caused by the change of electric current and the magnetic flux through the circuit of one's own, and the electromagnetic induction disturbance caused by this is due to It is caused by induced voltage but also occurs in cable or underground cable with shielded coating layer, and it is also severely changed when the distance from the power line is more than 50m.

따라서 유도장애를 방지하기 위한 대책은 주로 전자유도를 대상으로 이루어져야 하며, 이를 위해서는 예컨대 통신선로의 루트(route)를 변경하여 접근과 평형장을 감소시키거나 케이블을 지하화 또는 금속피복 차폐케이블로 바꾸는 등의 여러 가지 대책을 강구할 수 있다.Therefore, measures to prevent induction obstacles should mainly be aimed at electromagnetic induction. For this purpose, for example, the route of the communication line is changed to reduce the access and the equilibrium length, or the cable is grounded or the metal sheathed shielded cable. Various measures can be taken.

그러나 밀집된 도시구조에서 전력선을 피해 통신선로의 루트를 변경하기란 막대한 경비 등의 요인으로 사실상 불가하고, 차폐케이블이라 하더라도 전자유도를 효과적으로 억제하지 못하므로 해결책이 될 수 없다.However, it is virtually impossible to change the route of the communication line to avoid the power line in a dense urban structure, and even a shielded cable cannot be effectively solved because it does not effectively suppress the electromagnetic induction.

더욱이, 일반적인 통신용 케이블은 대부분 차폐용 금속피복을 구비하고 있지 않은 바, 유도장애가 상당히 심해 통신품질을 크게 떨어뜨릴 뿐 아니라 누화현상(혼선)도 빈발하고 있다.Moreover, since most communication cables do not have shielding metal coatings, the induced interference is so severe that not only the communication quality is greatly degraded, but also crosstalk is frequently occurring.

이에 따라, 전력선 및/또는 케이블을 받쳐주는 트레이를 철제로 구성하여 양단을 접지함으로써 인접하는 전력선으로 부터 통신선에 유도되는 유도전압과 전류가 트레이에서 흡수되도록 하여 통신선의 유도장애를 억제하고 있다. Accordingly, the tray supporting the power line and / or the cable is made of iron, and both ends thereof are grounded so that the induced voltage and current induced from the adjacent power line to the communication line are absorbed by the tray to suppress the induction disturbance of the communication line.

특히, 건물의 내부와 지하공동구에 함께 배선되는 전력선과 통신선은 대단히 근접되고, 경우에 따라서는 양자가 하나의 트레이에 동시에 배선되기도 하므로 전자유도에 의한 통신선로의 유도장애를 극복할 수 없다.In particular, the power line and the communication line which are wired together in the interior of the building and the underground cavity are very close together, and in some cases, both wires are simultaneously connected to one tray, so it cannot overcome the induction obstacle of the communication line due to electromagnetic induction.

종래의 케이블 트레이의 경우 다수개의 행거의 하단에 사각파이프를 너트로 고정하고, 사각파이프 위체 케이블 지지트레이를 고정하므로 설치가 번거롭고, 그리고 케이블 지지트레이 위에 전기 케이블이 그냥 올려져 있으므로 전기케이블의 피복에 손상이 쉽게 일어나는 문제가 있다.In the case of the conventional cable tray, the square pipe is fixed to the bottom of a plurality of hangers with a nut, and the square pipe upper cable support tray is fixed, which is cumbersome to install, and the electric cable is simply placed on the cable support tray. There is a problem that damage easily occurs.

이상과 같이 본 발명은 케이블보호관 내부에 케이블이 분리되어 삽입 지지되므로 인접하게 설치되는 통신케이블에 영향을 미치지 않게 되는 효과가 있고, 체결구조가 간편하여 일일이 볼트 체결을 하지 않고 지지트레이만 강봉에 체결하면 간 편하고 설치할 수 있는 효과가 있다.As described above, the present invention has an effect that the cable is separated and inserted into the cable protection tube so as not to affect the communication cable to be installed adjacently, and the fastening structure is simple, so that only the support tray is fastened to the steel bar without bolting. It is easy and easy to install.

또한 케이블보호관에 형성된 바홀에 중앙지지바가 삽입되어 강봉에 지지되면서 케이블보호관을 견고하게 지지할 뿐만 아니라 다시 지지트레이에 케이블보호관이 안착되어 지지되는 효과가 있다.In addition, the center support bar is inserted into the bar hole formed in the cable protection tube is supported by the steel bar, not only to firmly support the cable protection tube, but also has the effect that the cable protection tube is seated on the support tray.
