Ventilation device for cable trench of transformer substation
The invention discloses a ventilation device of a transformer substation cable trench, and belongs to the technical field of electric power installation engineering. The method comprises the steps that firstly, a barrel structure located outside is constructed through a flange and a segmented barrel shell, a positioning ring is arranged in a barrel, and an air barrel with through holes in the surface is installed on the positioning ring; the air duct serves as an air supply channel, and the conical ring and the tubular air outlet are formed in an inlet port and an outlet port of the air duct correspondingly and play a role in guiding airflow. The cones located at the two ends of the air duct are kept at the axis of the air duct and play a role in scattering airflow, and the blind holes in the surfaces of the cones are beneficial to reducing wind noise. The through holes in the surface of the air duct are combined with the filled sound-absorbing cotton, so that the sound attenuation effect can be further achieved. In addition, the wire box of the motor is kept outside the device, so that wiring and maintenance are facilitated; and the lifting appliance is arranged outside the barrel, so that the device can be conveniently lifted. The flow guide channel and the two-stage wind wheel can ensure a long air supply distance, the air speed is high, the flow is large, and the ventilation device is particularly suitable for ventilation of a cable trench of a transformer substation.
本发明公开了一种变电站电缆沟的通风装置，属于电力安装工程技术领域。本发明首先以法兰和分段筒壳构建了位于外部的筒体结构，筒体内部设置定位环，并将表面具有通孔的风筒安装于定位环上；风筒作为本发明的送风通道，其进出端口分别设置锥形环和管状出风口，对气流起到引导作用；位于风筒两端的锥状体保持在风筒轴线处，对气流起到散射作用，其表面的盲孔有助于降低风噪；风筒表面的通孔结合填充的吸音棉，可进一步起到消音效果。此外，本发明将电机的线盒保持在装置外部，便于接线和维护；在筒体外部设置吊具，便于装置的吊装作业。本发明的导流通道和两级风轮能确保较远的送风距离，其风速较快、流量较大，尤其适用于变电站电缆沟的通风。
