Abstract
The utility model relates to a movable fire-prevention partition board, particularly to a movable fire-prevention component for protecting a cabinet cable hole; and aims to overcome the problems of poor sealing performance and inconvenient construction during the cabinet reconstruction process in the prior art. The movable fire-prevention component for protecting the cabinet cable hole has the advantages of convenient construction and good fire-prevention performance. The main technical scheme is as follows: the movable fire-prevention component for protecting the cabinet cable hole comprises a fixed base plate and a movable insert plate; the base plate is fixed on a support, a slot is arranged on the base plate, and the insert plate is connected on the slot. The movable insert plate can slide along the slot, so that, after the cable is installed, the movable insert plate and the fixed base plate form a closed space, thereby achieving the fire-prevention function.
Description
Technical field
The utility model relates to a kind of movable fire barrier, relates in particular to the activity fire prevention assembly of a kind of use at protection screen cabinet cable cavern.
Background technology
In electric substation, because the cable bearer corrosion causes in many cable long period of soaking water, crust rots, and insulation damages very easily causes puncture short; Simultaneously because cable channel cover plate is not tight, the electroslag welding spark in the extraneous construction such as falls in the raceway groove at reason, all can cause ignition of cable.Therefore cable fire-proof regulation requirement when traversing to the positions such as cable interlayer, cable trough, cable tunnel of lower floor for cable, for the restriction cable fire spreads, must be carried out fire separation.Pass through the hole of wall, floor and dish cabinet for cable, use the fire prevention calking shutoff, cable shutoff thickness should be less than 8cm, and tight pore-free.Spread to reach the restriction cable fire, reduce cable and prolong the combustion ability, reduce the purpose of the device damage in the compartment.
At present, two kinds of materials are mainly used in the shutoff of secondary device control cable hole in the transformer station.
Inorganic fireproofing plugging: outward appearance is the cement sprills, mixed by silicate, carbonate, heat expansion agent, set retarder etc., fire endurance reaches 3 hours, and metal, rubber, plastics are not had corrosion, be applicable to that the shutoff cable passes through the hole of wall, floor and dish cabinet, cost is lower.
Organic fire prevention calking: outward appearance is a plasticine shape solid, is the organic mixture of fire-resistant inorganic salts and plasticity, and plasticity is preferably arranged under the normal temperature, is applicable to cooperate shutoff cable cavern and vertical shaft.
The shutoff main method and the requirement of the supporting control cable hole of secondary device are in the transformer station
(1), be the PLASTIC LAMINATED of 10mm at hole bottom laying depth, around hole mouth and cable, adopt organic putty to carry out closely knit shutoff, the organic putty thickness around the cable must not be less than 20mm.
(2), build, fill up hole with inorganic putty.
(3), do stitch with the place, slit of cable, stitch thickness is not less than 10mm, the not little dried 40mm of width of cable organic putty on every side at hole bottom PLASTIC LAMINATED.
(4), dish cabinet bottom carries out packing with the 10mm fire barrier, dividing plate install smooth firmly, technology breach, the slit of causing in the installation uses organic putty to be embedded in the hole hole densely.
(5), the gap, dish cabinet bottom can not packing arrived of PLASTIC LAMINATED, tightly seal reality with organic putty.
Because higher to the quality and the appearance requirement of fireproof blocking, on-the-spot shutoff work generally entrusts professional construction troop to carry out.Consider the cost of fireproof requirement and enforcement, specialized team often adopts with fixed fire barrier as substrate, and inorganic putty is as mainly cramming material, and the organic putty of bound fraction carries out shutoff.In the equipment normal course of operation, such shutoff requirement up to specification, but in the scrap build process, during for needs increase or minimizing part control cable, will bring very big inconvenience to work progress.
Fixed fire barrier carries out perforate according to the quantity of control cable, its four limits bolt, and except the slit between the cable, remainder all seals with inorganic putty.When needing to extract out waste and old cable in the construction or increasing new cable, must in cable floor, screw out set bolt one by one with box spanner, will move near the inorganic putty of cable with hammer and pointed file and strike pine.This process not only expends time in and energy, and is easy to cause moving the cable insulation damage near the work of the operation cable, and the situation of DC earthing even circuit breaker action takes place, and such accident repeatedly takes place in practice of construction.
According to the guideline lives requirement of electronic product, the microcomputer type relay protection operation hours is 10 to 12 years, expire and must change, so in the transformer station this kind equipment more change jobs very frequent.In work progress since original fireproof blocking facility can not in time repair after destroyed, the fire prevention measure imperfection, the interim shutoff quality of cable cavern does not reach fire protection requirement, very easily causes the expansion of the intensity of a fire and spread under the situation of extraneous breaking out of fire.
Summary of the invention
The utility model mainly is defectives such as, construction inconvenience not good at prior art sealing state in screen cabinet transformation process, has designed the activity fire prevention assembly of a kind of facility of constructing, protection screen cabinet cable cavern that the fire prevention state is good.
Above-mentioned technical problem of the present utility model is implemented by the following technical programs:
The activity fire prevention assembly of protection screen cabinet cable cavern comprises fixed base plate and active plugboard.Base plate is fixed on the support, and base plate is provided with slot, is connected with active plugboard on the slot.Active plugboard can slide along slot, after cable installs, forms confined space with fixed base plate, plays the fireproof effect.
The activity of above-mentioned protection screen cabinet cable cavern fire prevention assembly, as preferably, described fixed base plate is fixed on the support by set bolt, can be for convenience detach.
The activity of above-mentioned protection screen cabinet cable cavern fire prevention assembly, as preferably, described active plugboard is connected with fixed base plate by movable bolt.Active plugboard is according to the needs of installing, and the number of times that is moved is more, therefore adopts movable bolt to connect, and can make things convenient at any time and move.
The activity fire prevention assembly of above-mentioned protection screen cabinet cable cavern, another kind of optimal way is that described plate is connected with slot by movable bolt.Plate is connected by movable bolt with slot and is fixing, take in sail bolt with the contacting of base plate, and slot itself has depression, made things convenient for the fixing of bolt.
The activity fire prevention assembly of above-mentioned protection screen cabinet cable cavern as preferably, is coated with organic putty outside the described cable.But organic putty is the fireproof organic material, plays the effect of parcel cable simultaneously.
The activity fire prevention assembly of above-mentioned protection screen cabinet cable cavern as preferably, is provided with the fire prevention bag between described organic putty and the support.The fire prevention bag is the fireproofing installation that plays a major role for inorganic filler.
In sum, the utility model is compared with prior art and is had following advantage:
Owing to adopted the double design of active plugboard, fixed base plate, made things convenient for the installation of cable.Simultaneously, organic putty separates with inorganic putty, and adopts bulk form to install, and makes installation further convenient.Form a kind of modular installation form.
