4 FAQs about Surge-proof communication power supply cabinet for tunnels

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 are the principles of uninterruptible power supply (UPS)?

However, some identical principles can be noted, such as: The installation of a device that can compensate for a total loss of power supply. This system (uninterruptible power supply (UPS), diesel generator., etc.) supplies electricity to equipment critical for safety, during a limited period of time.

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).

What is a preferred power supply architecture for DSL applications?

A preferred power supply architecture for DSL applications is illustrated in Fig. 2. A push-pull converter is used to convert the 48V input voltage to +/-12V and to provide electrical isolation. Synchronous buck converters powered off of the +12V rail generate various low-voltage outputs.
