Substation prefabricated cable channel fireproof wall

Abstract

The invention discloses a substation prefabricated cable channel fireproof wall, and relates to the field of power transmission and distribution cable line channel fireproof fixing devices. The substation prefabricated cable channel firewall comprises a frame, steel bars and a fireproof insulating material, wherein the length of the frame is 800-1200mm, the width is 800-1200mm, the thickness is 350-400mm, the fireproof insulating material is fixedly connected to the internal part of the frame, the fireproof insulating material is provided with 16 cable threading holes, and the horizontal direction and the vertical direction of the frame are respectively provided with three steel bars. The substation prefabricated cable channel fireproof wall is mainly applied to power transmission and distribution cable line channels and substation cable layers, is mainly convenient for cable fixation, reduces the number of removing times of the cable fireproof wall, prevents expansion of a fire disaster caused by cable winding when a cable breaks down and is on fire, and ensures normal operation of a cable line.

Description

technical field [0001] The invention relates to the field of fireproof fixing devices for transmission and distribution cable channels, in particular to a prefabricated cable channel firewall in a substation. Background technique : [0002] With the widespread use of power cables, the deployment of power cables in cable channels and firewalls directly affects the safe operation of cable lines. The reason is that cable firewalls generally adopt brick wall structures. With frequent construction, cables Due to the requirements of exhibition, the firewall in the station must be removed frequently, but due to the requirements of safety measures such as small animals, the firewall must be restored in a short time, and the cable passage is narrow and the brick wall materials are not easy to transport and construct. Taking the 110kV Longtan Substation in 2014 as an example, due to the construction of cable laying, the cable firewall was removed and repaired more than 20 times throu...

[0002]With the widespread use of power cables, the deployment of power cables in cable channels and firewalls directly affects the safe operation of cable lines. The reason is that cable firewalls Generally, the brick wall structure is adopted. With the frequent construction and the requirements of cable deployment, the firewall in the station must be removed frequently. However, due to the requirements of safety measures such as preventing small animals, the firewall must be restored in a short time, and the cable passage is narrow. Brick wall masonry materials are not easy to transport and construct

Taking the 110kV Longtan Substation in 2014 as an example, due to the cable laying construction, the cable firewall was removed and repaired more than 20 times throughout the year, and the cost was more than 30,000 yuan

Secondly, the current cable firewall connects the cable channel and the cable layer of the substation. Since there is no fixed isolation, the cables are all entangled together, and the ventilation and heat dissipation are poor, which is prone to fire problems.
