Preferably, the other end of the fire probe pipe is of a sealed structure.

Preferably, bolt holes are formed in four corners of the upper end face of the fixing plate.

Preferably, the number of the fixing strips is provided with a plurality of groups.

Preferably, the top plate is a hollow-out structure.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a be provided with fire-exploring tube, valve and fire extinguishing agent jar and make its use of mutually supporting, can constitute fire extinguishing system, when oil-immersed high voltage transformer takes place the ignition, ignition department intensifies in the twinkling of an eye to with the fire-exploring tube burn out of ignition department, spout a large amount of fire extinguishing agents and put out to the ignition after the fire-exploring tube burns out, thereby reduced the production that oil-immersed high voltage transformer burns out the phenomenon, also promoted oil-immersed high voltage transformer's security performance simultaneously.
