The technical scheme that its technical problem that solves the utility model adopts is: the automatic nitrogen filling fire extinguishing device of a kind of Long-distance Control, comprise oil tank of transformer and FHC and the Fire Control Cabinet that is connected with FHC, described oil tank of transformer side offers oil exit pipe, be provided with nitrogen cylinder in the described FHC, be communicated with on the nitrogen cylinder and annotate the nitrogen pipe, the end of annotating the nitrogen pipe passes FHC and stretches into the oil tank of transformer bottom, be provided with the transformer connection case in the described oil tank of transformer, transformer connection case one end is connected with FHC by cable, the other end is connected with respectively that fire detector is connected and cut-off valve, cut-off valve is communicated with gas relay by pipeline, gas relay is connected with oil tank of transformer, described transformer oil box top is equipped with fire detector, the fire detector output is connected with Fire Control Cabinet, Fire Control Cabinet output output Long-distance Control output signal.

Described transformer oil box top also is equipped with the camera for situation in the monitoring oil tank of transformer, and camera is connected with Fire Control Cabinet.

Connected mode between described fire detector and the Fire Control Cabinet is: wireless connections or wired connection, wireless connections are at fire detector the blue teeth wireless output signal to be installed, and in Fire Control Cabinet the blue teeth wireless corresponding with the blue teeth wireless output signal are installed and are received signal; Wired connection is directly fire detector to be connected by lead with Fire Control Cabinet, then by Fire Control Cabinet Long-distance Control output signal.

The beneficial effects of the utility model are: the automatic nitrogen filling fire extinguishing device of described Long-distance Control, this device need not water source and other medium, floor space is little, the building-up work amount is little, compact conformation, the automaticity height is easy to design, addressing and installation, be not subjected to condition restriction such as geographical environment, easy to maintenance; Adopt hermetically sealed design, do not exist antirust, foreign material, phycomycete, problem such as antifreeze; Integrate detection, warning, fire extinguishing, monitoring system, the course of work need not artificial intervention, realizes the automation control of overall process; By introducing intelligent industrial control technology, the misoperation of anti-locking system, sensitivity and the reliability of raising extinguishing device system.
