Abstract

The invention discloses an electrical system for a highway tunnel. The electrical system comprises a power supply system, an illumination system, a ventilation system, a traffic control system, a firehazard alarm system, a video monitoring system, a broadcast and emergency telephone system and a control center; the power supply system supplies power to the different systems and ensures system operation; the illumination system and ventilation system are controlled automatically to ensure illumination and ventilation of the tunnel; lane indication of the traffic control system is realized by PLC control, and information of an information board is provided by the control center; the fire hazard alarm system and video monitoring system transmit information to the control center via a detector and a camera respectively; and the broadcast and emergency telephone system communicates with the control center bidirectionally to realize alarm and alarm notification. Subsystems are optimized indesign aimed at special construction and complicated electrical control of the highway tunnel, and the electrical system is characterized by being safe and stable.

Description

technical field [0001] The invention relates to the field of electrical system design, in particular to an electrical system used in expressway tunnels. Background technique [0002] In today's society, expressways play a pivotal role in people's daily life, which can speed up the transmission of logistics information, promote the development of the national economy, improve transportation convenience, and serve the people. For expressways built in mountainous areas, since there are many hills in remote mountainous areas, expressways have high requirements for plane alignment and slope. In order to shorten the driving mileage of the expressway, provide a safe driving road for vehicle drivers, improve the convenience of traffic, and reduce the driving time, when building expressways, when encountering hills, tunnels are often used to build expressways. . The advantage of the tunnel is not only to shorten the driving mileage of the expressway, but also to avoid the impact of...
