Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wire-based seismic-resistant cable tray and duct system for earthquake-

The present invention relates to an earthquake-resistant cable tray and a duct, and more particularly, to a cable supporting structure for a cable bus and a bus duct, wire cable trays and ducts for providing a tensioned seismic structure with tension wires.

A cable tray or a cable duct is a conductor for connecting a transformer or an electric power distribution board to a load device, and is responsible for receiving and distributing electric power. It is very important to distribute electricity smoothly and efficiently as well as provide a stable supply of electric power.

First, the tray is installed in the ceiling of the building by installing a diaphragm bolt, and mounting it on a bolt or a mount that is installed and mounting the electric wire. Thus, the tray is exposed to the outside and the electric wire is bundled into a ladder- .

On the other hand, the duct is constructed by a conductor made of copper or aluminum inside the housing and made of a, b, and c phases, moved to the required area and then used for branching. As shown in Fig.

These trays are vulnerable to fire because everything is exposed and the ducts can pass safely through the enclosure, but internal debris or insulation failure can cause internal shorts.

Accordingly, in recent years, the importance of earthquake-resistant seismic design has been emphasized on the trays and ducts provided in the buildings as well as the buildings themselves, and seismic design has been carried out.

In addition to buildings, traces and ducts also have their own seismic design structure, which is important in preventing earthquakes from affecting the distribution of buildings or cutting off the supply of electricity. Furthermore, It is a big function to prevent.

On the other hand, Korean Patent Laid-Open Publication No. 10-2016-0044445 corresponding to Conventional Technology 1 "Chain channel system having electric tray for up-down absorption" And more particularly, to an up-down absorption type electric tray earthquake-resistant channel system that absorbs vibration to prevent breakage and deformation of electric wires installed in an electric tray. However, the conventional technique 1 is only capable of top and bottom shock absorption, but has a weak point in horizontal impact.

In addition, Korean Patent Laid-Open Publication No. 10-2010-0089153 "Electric power busway duct improved vibration-proof ability ", which corresponds to the conventional art 2, And more particularly, to a technique relating to an improved vibration-damping power bus duct that can flexibly cope with dynamic vibration during ship operation.

However, according to the conventional technology 2, the expansion and contraction coupling device 200 is interposed between the power bus ducts in which the bus bars 120 of a rectangular cross section pass through the inside of the enclosure 110, And extend and contract in the left and right directions and the twist direction.

However, the conventional art 2 has a limitation in that it is affected by the damage due to the earthquake shock as compared with the continuous system because of the limitation of the method of supporting the two enclosures 110 by using the expansion joint coupling device 200.

Korean Patent Laid-Open Publication No. 10-2012-0030224 " Holder of building equipment with vibration < RTI ID = 0.0 > proof " It is possible to prevent damages to building equipment by preventing earthquake, strong shock or building equipment, such as ducts, by absorbing minute vibration caused by air flowing in the inside, The present invention relates to a technique for providing a seismic isolation and an earthquake-resistant platform capable of protecting against a car risk.

However, the conventional technique 3 is similar to the conventional technique 2, but is fixed by using a vertical fixture centered on two horizontal fixtures corresponding to a vertical state, not horizontal, in the directionality thereof. There is a limitation in that it is inevitably affected by the damage caused by the earthquake shock as compared with the continuous system because of the limitation of the method of supporting the same as the conventional art 2 by providing the earthquake-resistant platform.

In addition, the Korean Utility Model Registration Registration No. 20-0480222, " Interference checking member "corresponding to Conventional Technology 4, implements the same shape as the bus duct to be installed using the member in the same dimension The present invention relates to a technique for providing a member for confirming whether or not an interference has occurred when installing a bus duct in advance.

However, the conventional technique 4 includes a multi-step pipe body capable of extending or shortening the length, and a coupling means provided at both ends of the multi-step pipe body, so that the same shape as the bus duct to be installed using the member is realized with the same dimensions, It is possible to prevent occurrence of interference with the surroundings in the actual installation of the bus duct by making it possible to check beforehand whether or not interference occurs at the time of the installation of the bus duct and to limit the point that it can not provide a method of actually absorbing the external force due to an earthquake impact have.
