the utility model provides an electric power high voltage cable fire prevention extinguishing device, includes cladding fire prevention board and the fire extinguishing pipe of integration on the fire prevention board around the cable to and the installing support constitutes, the fire prevention board is by fire prevention material, fire-resistant fiber cloth and the integrative pressfitting molding of fire-resistant glue, fire extinguishing pipe fills fire extinguishing agent in by the protection tube and constitutes, the installing support is by non-magnetic stainless steel material punching press weld forming.

In any of the above schemes, preferably, the fireproof plate is made of magnesium oxide, ceramic fiber cloth and refractory glue, and is integrally pressed and molded, the fire extinguishing pipe is formed by filling heptafluoropropane in a protection pipe, the heptafluoropropane is non-conductive, non-corrosive, non-residue and non-destructive to equipment, the fire extinguishing pipe can be customized in various lengths according to field conditions, the mounting bracket is made of a non-magnetic material, the surface of the mounting bracket is coated with fireproof paint, the fire extinguishing pipe can be fixed and integrated on the fireproof plate through a buckle, and the fireproof plate is fixed to the mounting bracket through bolts

Compared with the prior art, the utility model provides a following beneficial effect has:

1. through setting up the PLASTIC LAMINATED, the PLASTIC LAMINATED material is fire-resistant high temperature resistant materials such as magnesium oxide, ceramic fibre and fire-resistant glue, can bear the high temperature that exceeds 1500 ℃ for a long time and do not become invalid, effectively prevents the intensity of a fire to spread.

2. The fire extinguishing pipe is integrated in the fire preventing and extinguishing device, the fire extinguishing pipe sprays fire extinguishing agent when meeting fire, flames are timely extinguished, loss is reduced, meanwhile, the fire extinguishing pipe is low in cost, small in size and simple and easy to install, a whole cable can be laid, and the whole cable can be fully covered and fully protected.
