Description

Arrangement structure of lighting fixtures in a cable tunnel with a diameter of 3.5 meters

technical field

The utility model relates to a tunnel lighting system, in particular to an arrangement structure of lighting lamps in a cable tunnel with a diameter of 3.5 meters.

Background technique

With the rapid development of the national economy and the continuous improvement of the living standards of the people, the load of Shanghai power grid has been increasing year by year. In order to meet the needs of the development of Shanghai's electric power system and ease the power supply pressure in the central urban area, 500kV substations have penetrated into the downtown area, and power cables will be used for the 500kV transmission lines in the urban area. 500kV cables have high requirements for heat dissipation around the cables due to their transmission capacity requirements. The original laying methods commonly used in Shanghai, such as pipe arrangement, direct burial, and cable trenches, are no longer suitable for the needs of 500kV cables. Therefore, the construction of special tunnels for electric power has become the main way of laying 500kV cables.

For electric power tunnels, in addition to the cable laying requirements in the cable tunnel, the auxiliary facilities for the cables in the tunnel, including ventilation systems, power systems, lighting systems, drainage systems, monitoring systems, communication systems, fire protection systems, All links such as the grounding system are considered together in the design of the tunnel.

Contents of the invention

The purpose of this utility model is to provide a convenient and energy-saving arrangement of lighting fixtures in a cable tunnel with a diameter of 3.5 meters in order to overcome the above-mentioned defects in the prior art.

The purpose of this utility model can be achieved through the following technical solutions: an arrangement structure of lighting fixtures in a cable tunnel with a diameter of 3.5 meters, which is characterized in that it includes a plurality of LED lights, which are evenly arranged on the top of the tunnel, and between adjacent LED lights The distance between them is 7-8m.

The sidewalls on both sides of the tunnel are provided with horizontal cross-arms, and cables are hung on each horizontal cross-arm.

The same side of the tunnel is provided with at least two horizontal cross arms, and each horizontal cross arm is arranged in parallel up and down.

The LED lamps are arranged at the center of the top of the tunnel, and the interval between adjacent LED lamps is 7.2m.

The single lamp power of the LED lamp is 2×18W, and it is equipped with an electronic ballast.

Compared with the prior art, the utility model adopts high-efficiency energy-saving fluorescent lamps with a single lamp power of 2×18W and is equipped with electronic ballasts. The lamps and lanterns have functions such as moisture-proof and rust-proof. The lighting fixtures in the tunnel are ceiling-mounted on the top of the tunnel, and the longitudinal spacing is in accordance with the multiple of the segments. Three-phase power supply is adopted, and each phase is balanced, with moderate illumination and energy saving.
