Description
Technical Field
The invention relates to the technical field of converter station valve side fireproof plugging, in particular to a fireproof plugging reinforcing structure.
Background
Converter transformers (converter transformers for short) and converter valves are core equipment of a converter station and play a role in connection and coordination between an alternating current power grid and a direct current circuit. The converter transformer body is arranged outside the converter valve hall, each converter transformer room is isolated by a firewall, a large amount of insulating oil is stored in the converter transformer, and the network side sleeve is connected with the alternating current system outside the converter valve hall; the valve side sleeve penetrates through a fireproof blocking wall of the valve hall and then is connected with a valve group in the valve hall, and the converter transformer valve side sleeve lifting seat is generally inserted into the valve hall. A hole is reserved in the position, where the firewall of the valve hall enters the converter transformer valve side sleeve, so that the converter transformer is convenient to put in place, and the hole is blocked after the converter transformer is put in place. At present, the large hole plugging material for plugging the opening of the sleeve at the converter transformer side of the domestic converter station selects a structural rock wool composite fireproof plate, and the small hole plugging adopts rock wool for filling joints, a silicon rubber waterproof sealing sleeve for sealing and a stainless steel pipe card for fixing. Most of structural rock wool composite fireproof plates adopt Parac fireproof plates, although the fireproof limit of the plates is usually more than 3 hours (under a standard temperature rise curve and a non-hydrocarbon temperature rise curve), the fireproof plugging system consisting of the Parac plates can only be realized by increasing the thickness of the Parac plates if the fireproof plugging system needs to further improve the fireproof limit, so that the construction is inconvenient, the fireproof limit is not obviously improved, and the use requirement cannot be met.
Disclosure of Invention
Therefore, the technical problem to be solved by the invention is to overcome the defects of low fire resistance limit and poor protective performance of the converter town blocking structure in the prior art, so that the fireproof blocking reinforced structure with high fire resistance limit and good protective performance is provided.
In order to solve the technical problem, the invention provides a fireproof sealing and reinforcing structure which is arranged on one side of a structural rock wool board and comprises:
the aluminum silicate needle-punched carpet comprises a shielding panel, a stainless steel keel, a composite aluminum silicate plate and an aluminum silicate needle-punched carpet which are sequentially arranged from outside to inside, wherein aluminum silicate fiber cotton is filled in the middle of the stainless steel keel.
The fireproof plugging reinforcing structure is characterized in that the shielding panel, the stainless steel keel, the composite aluminum silicate plate and the aluminum silicate needle-punched blanket are sequentially arranged from the indoor side to the outdoor side.
Fire prevention shutoff reinforcing structure, compound aluminum silicate plate includes first metal decking, first inorganic PLASTIC LAMINATED, the inorganic PLASTIC LAMINATED of second and the second metal decking that sets gradually by indoor side to outdoor side.
The fireproof blocking reinforcing structure is characterized in that the first metal panel and the second metal panel are stainless steel panels, and the thickness of each stainless steel panel is 0.5-0.6 mm.
The fireproof blocking reinforcing structure is characterized in that the first inorganic fireproof plate and the second inorganic fireproof plate are magnesium inorganic fireproof plates, and the thickness of each magnesium inorganic fireproof plate is 10-30 mm.
According to the fireproof blocking reinforcing structure, the shielding panel is an austenitic stainless steel profiled corrugated shielding panel, and the thickness of the shielding panel is 1-2 mm.
The fireproof blocking reinforcing structure is characterized in that the stainless steel keel is an austenite nonmagnetic stainless steel keel.
The thickness of the aluminum silicate needled blanket is 10-20 mm.
In the fireproof blocking reinforcing structure, a first aluminum silicate fiber blanket, a magnesium inorganic fireproof plate and a second aluminum silicate fiber blanket are sequentially filled between two adjacent composite aluminum silicate plates in the height direction.
The fireproof blocking reinforcing structure is characterized in that a stainless steel connecting piece is arranged at the joint of the shielding panel and the wall body, and a third aluminum silicate fiber blanket is filled between the stainless steel connecting piece and the shielding panel.
The technical scheme of the invention has the following advantages:
1. according to the fireproof blocking enhanced structure provided by the invention, the shielding panel, the stainless steel keel, the composite aluminum silicate plate and the aluminum silicate needled blanket are sequentially arranged on one side of the rock wool plate with the original structure from outside to inside, so that when the weak link of the original fireproof blocking structure needs to be enhanced, only the aluminum silicate needled blanket, the composite aluminum silicate plate, the stainless steel keel and the shielding panel need to be sequentially installed on the basis of the original structure, and the aluminum silicate fiber cotton is filled in the stainless steel keel, so that the original structure does not need to be dismantled, and the construction is convenient. When the outdoor conflagration breaks out, because the setting of reinforcing structure, because of the low, chemical stability and the thermal stability of the heat conductivity coefficient of aluminium silicate acupuncture blanket are good, stainless steel fossil fragments and shield panel have higher fire endurance, consequently on the basis of guaranteeing that support intensity and thickness do not obviously increase for high temperature and blasting are effectively blocked, have improved the fire endurance of fire prevention shutoff reinforcing structure, have improved barrier propterty.
2. The fireproof blocking reinforcing structure provided by the invention is characterized in that the shielding panel, the stainless steel keel, the composite aluminum silicate plate and the aluminum silicate needled blanket are sequentially arranged from the indoor side to the outdoor side. When a fire disaster occurs outdoors, high temperature or explosion is firstly blocked by the structural rock wool plate, so that the strength of the high temperature or explosion reaching the reinforced structure is reduced, and meanwhile, because the thermal conductivity coefficient of the aluminum silicate needled blanket is low, and the fire resistance limit of the shielding panel close to the indoor side is higher, the protection performance is obviously improved.
3. The invention provides a fireproof plugging reinforcing structure, wherein a composite aluminum silicate plate comprises a first metal panel, a first inorganic fireproof plate, an aluminum silicate panel, a second inorganic fireproof plate and a second metal panel which are sequentially arranged from the indoor side to the outdoor side. The setting of symmetry core structure not only makes the fire behavior of whole structure both sides unanimous, sets up the first metal decking and the second metal decking that fire behavior is the best in the outside simultaneously, under the prerequisite of not increasing thickness significantly, has further improved the fire endurance.
