Description

Distribution board equipped with arc, hot spot fire location detection and automatic fire extinguishing device

The present invention relates to a switchboard, and more specifically, to a switchboard equipped with an arc and hot spot fire location detection and automatic fire extinguishing device.

Since high voltage/high current flows in switchboards, they are constantly exposed to dangers such as arc discharge or fire. It is virtually impossible for administrators to monitor 24 hours a day.

However, when a fire breaks out, it can lead to a large-scale fire, so it is essential to check whether a fire breaks out at an early stage and take initial measures to prevent the spread of the fire.

However, since panels and wires are provided inside the door for safety and security of the switchboard, by the time fire extinguishing facilities in the building such as sprinklers are operated, a large fire has already spread.

Accordingly, a means capable of accurately recognizing an initial fire inside a switchboard and responding to an initial fire is required.
