Problems solved by technology

The heat dissipation of the cable joint is not good, and it is easy to generate heat accumulation. Once the joint explosion accident occurs, the energy has nowhere to be released, and the protection box will burst open instantly, causing a fire and burning adjacent cables, which is not conducive to the safe operation of the cable and leads to the power supply of the city.

Embodiment Construction

[0019] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, it is a non-humid environment fuse type cable joint fire protection box provided by the present invention. The inside of the fire protection box 3 has a cavity for accommodating the cable joint 2; the fire protection box 3 is provided with a fireproof A heat dissipation component, and a fuse-type drive mechanism connected to the fire-proof heat dissipation component; the fuse-type drive mechanism has a melting point compatible with the preset temperature warning value; when the real-time temperature in the fire protection box 3 does not exceed the preset temperature When the warning value is reached, the fire-proof and heat-dissipating parts are in the normally open state, which is conducive to the heat dissipation of the cable joint 2; when the real-time temperature in the fire ...

Abstract

The invention discloses a fusing type cable joint fireproof protection box used in non-moisture environment. The inner side of the fireproof protection box is provided with a cavity used for accommodating a cable joint. The fireproof protection box is provided with a fireproof heat dissipation part and a fusing type driving mechanism connected with the fireproof heat dissipation part. The fusing type driving mechanism has a melting point cooperated with a preset temperature alarm value. When a real-time temperature in the fireproof protection box does not exceed the preset temperature alarm value, the fireproof heat dissipation part is in a normally open state. When the real-time temperature in the fireproof protection box exceeds the preset temperature alarm value, and a fire hazard happens, the fusing type driving mechanism is fused, and the fireproof heat dissipation part is closed. The fusing type cable joint fireproof protection box is advantageous in that the heat dissipation of the cable joint is facilitated, and an explosion or fire hazard accident caused by heat energy concentration is effectively reduced; once the explosion or the fire hazard happens, flames are effectively isolated, and the fire is prevented from spreading to other cables disposed in the same tunnel.

Description

technical field [0001] The invention relates to a fire protection box for cable joints, in particular to a fuse type fire protection box for cable joints used in non-humid environments, which is suitable for fire protection in densely populated places such as cable tunnels, cable trenches, and cable interlayers. Background technique [0002] Cable fires mostly occur at cable joints. The cable intermediate joint is the weakest link in the safe operation of the power system. Cases of cable disconnection, short circuit, explosion and even major accidents caused by overheating of the cable joint are not uncommon. In the prior art, the high-voltage cable joints in some cable tunnels are arranged in closed protective boxes, and the interior of the protective boxes is filled with fireproof blocking materials. The heat dissipation of the cable joint is not good, and it is easy to generate heat accumulation. Once the joint explosion accident occurs, the energy has nowhere to be rele...
