What type of power does a tunnel need?
Meet the needs under all operational situations (normal, degraded, critical, emergency). The power required for supplying a tunnel is directly related to the nature and number of equipment installed in it. Depending on the amount of electrical energy required (kWh), power may be supplied in low voltage or high voltage (Fig. 1).
How many power sources should a utility tunnel have?
All electrical loads within the utility tunnel are closely related to people's livelihoods. Interruption of not be lower than level two. The system should be powered by two circuits, using a segmented single bus. If conditions permit, it can be designed with two power sources. These two power sources are
What are the requirements for supplying power to a tunnel?
Most of the tunnel equipment and systems require electrical energy to operate. Therefore, equipment for supplying power to the tunnel must be installed. This installation has to satisfy two essential requirements: Meet the needs under all operational situations (normal, degraded, critical, emergency).
What is the function of utility tunnels?
Utility tunnels serve as bot h normal operation. It can be said that the construction level of the power supply and distribution system within utility tunnels directly determines the quality of the tunn els' engineering.
