Fireproof system for cable

Abstract

The invention discloses a fireproof system for a cable. The fireproof system for the cable comprises a hole plate, a cable hole and an extension plate, wherein the hole plate is used for clamp connection and plugging; the cable hole is formed in the hole plate; the extension plate is arranged at the outer side of the hole plate and is used for extending the hole plate; each of the hole plate and the extension plate comprises a first vermiculite plate layer, a second vermiculite plate layer, a keel layer and a third vermiculite plate layer which are sequentially arranged from outside to inside;the first vermiculite plate layer and the second vermiculite plate layer are fixed on the keel layer through screws; the third vermiculite plate layer is fixed on the keel layer through screws; and the hole plate is formed by splicing two plates with semicircular notches. The fireproof system for the cable has the advantages that through the design structural form of the hole plate and the extension plate, the clamp connection of the cable and the extension of a fireproof position are realized; meanwhile, the hole plate and the extension plate are made into a multi-layer combined structure; and through the reasonable arrangement of a multi-layer fireproof support structure, the integral heat insulation and fireproof function and the structural strength of the fireproof system are greatlyenhanced.

Description

technical field [0001] The invention relates to the technical field of fire safety, in particular to a fire protection system. Background technique [0002] In recent years, with the accelerated pace of power grid construction, the level of smart grid construction has gradually increased, and the number of substations has increased significantly. The importance of substations cannot be overstated. Cables are an important part of the normal operation of substations, almost throughout the entire substation, and are important carriers for power transmission and signal transmission in substations. If a cable fire breaks out, it will not only cause casualties to surrounding personnel, but also severely block the normal production work of the power grid production department, causing huge economic losses, and will also affect the growth of the local economy and the daily life of people in nearby areas, costing a lot of money human, material and financial resources. However, sin...

Problems solved by technology

If a cable fire breaks out, it will not only cause casualties to surrounding personnel, but also severely block the normal production work of the power grid production department, causing huge economic losses, and will also affect the growth of the local economy and the daily life of people in nearby areas, costing a lot of money human, material and financial resources

However, since the monitoring measures and fire protection measures for the safe operation of cables are relatively simple, day and night monitoring cannot be carried out within the scope of the whole station, and accidents such as cable fires or unsafe hidden dangers during its operation cannot be timely and effectively controlled. The safe operation of the substation will be seriously affected, so the research on the performance of fire protection measures for substation cables is urgent
