Abstract

The invention discloses a fire wall of a cable channel. The fire wall is arranged in the cable channel; the cable channel corresponding to the bottom of the fire wall is internally provided with a U-shaped groove; a septum is arranged in the middle of the U-shaped groove; and the fire wall is provided with a reversed U-shaped groove into which the septum is inserted. The fire wall has simple structure and fireproof function, thus fire does not spread to the other side once a fire disaster happens; in addition, the septum is arranged in the middle of the U-shaped groove, so that water can smoothly flow to the other side from one side by a diversion passage under the condition that the cable channel is filled with the water.

Description

technical field [0001] The invention relates to a cable trench firewall, in particular to a cable trench firewall which is convenient for drainage. Background technique [0002] The secondary system of the substation needs to be connected by many cables. For the sake of safety, a firewall is built at intervals in the cable trench where the cables are laid to prevent the fire from spreading along the cables to both sides once a certain cable is ignited. At present, the main focus of the cable trench firewall is on the materials of the firewall, cable fixing and sealing, and other aspects, such as drainage, are rarely considered. In case of cloudy and rainy days, rainwater will enter the cable trench. For drainage, water pumps must be erected to draw water; The first two methods are more troublesome, and the latter method is limited in that if the small hole is opened too small, it is not conducive to drainage; if it is opened too large, it will destroy the effect of the fire...
