Abstract

The invention relates to a detachable type cable bridge firewall and a manufacturing method. The detachable type cable bridge firewall comprises a wall body, multiple cable bridges, fireproof drawersand a fireproof sliding plate. The multiple cable bridges are arranged in a layered manner. The cable bridges are arranged on the wall in a penetrating manner and stretch out of the wall. The wall comprises a detachable first side wall, and the plane where the first side wall is located is parallel to the length direction of the cable bridges. An outlet and inlet opening is formed in the wall, andthe first side wall is used for sealing the outlet and inlet opening. The fireproof drawers are arranged in the wall and are arranged on the cable bridges. The fireproof drawers are pulled out from the outlet and inlet opening and enter the wall from the outlet and inlet opening. The wall and the fireproof drawers are used for placing fireproof bags. The fireproof sliding plate is arranged between the cable bridges and the fireproof drawers. The firewall is convenient to demount, the construction time is better shortened, and damage to the firewall due to improper operation is effectively avoided. The manufacturing method of the firewall is simple, operation is easy, the firewall demounting cost is reduced, and the efficiency for demounting and mounting the firewall is improved.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a detachable cable bridge firewall and a manufacturing method. Background technique [0002] At present, the cable tray firewalls used in substations generally adopt an integrated installation structure, that is, the multi-layer cable tray firewalls are an integral structure and cannot be disassembled at will. When making a firewall, first use the fireproof corners to splice into a frame structure, fill the inside of the firewall frame structure with fireproof bags, then use fireproof partitions to seal the frame structure on all sides, and riveted and fixed with blind rivets to form a complete firewall. Such an integrated firewall structure can play a good role in delaying the spread of fire along the cable tray. However, this integrated firewall is also inconvenient in actual use, especially during the secondary cable laying construction, the disassembly of ...
