Anti-riot measure reaches explosion-proof by the way of H profile steel and strip combination, solves envelope of preventing fires in transformer Fire explosion
Stifled stability avoids the change of current from becoming fire spreading to valve hall, guarantees valve hall safety.
2, the utility model is designed using sliding door, becomes maintenance and maintenance convenient for the later period change of current.
3, hole is blocked using nanometer medium fire proofing material, fire insulation performance is more preferable.
Detailed description of the invention
Figure 1A is the schematic side view of the closure blast resistance construction of the utility model.
Figure 1B is the schematic side view of the closure blast resistance construction of the utility model.
Fig. 2 is Section A-A schematic diagram in Fig. 1.
Fig. 3 is section B-B schematic diagram in Fig. 1.
Specific embodiment
The utility model protects a kind of ultrahigh-voltage converter transformer valve Room side firewall to block blast resistance construction.
The block-up position of firewall 1 is the rectangle hole of change of current change and valve hall connection position, can specifically include two kinds of rulers
It is very little, it is respectively as follows: hole 1:6145 × 6920mm；Hole 2:6990 × 7680mm.The plugging structure for blocking rectangle hole can be used
The mesoporous nano fireproof heated board 2 of 200mm thickness is fixed on L80 × 50 × 7 angle steel of armored concrete firewall hole surrounding
On frame, gap between mesoporous nano fireproof heated board 2 and angle frame is filled using refractory mortar.Such as Figure 1A, Figure 1B and Fig. 3
It is shown, casing macropore 21 is provided on mesoporous nano fireproof heated board 2, for wall bushing 7 is arranged.
As shown in Figure 2 and Figure 3, become the single layer that side is respectively provided with two-way folding in the valve hall side of firewall plugging structure and the change of current
Sliding door 4 adds the explosion-proof sliding door 3 of two-way folding on the outside of the single layer sliding door 4 that the change of current becomes side.Single layer sliding door 4 and anti-
It include the hole passed through for wall bushing 7 on quick-fried sliding door 3.The positioning of the upper and lower end of single layer sliding door 4 and explosion-proof sliding door 3
The push-and-pull move in sliding rail is realized in horizontal slide rail 51,52, and by carriage such as pulley, and the both ends of guide rail can root
According to actual conditions, limiting device is set.
10mmQ345 steel plate can be used in above-mentioned single layer sliding door 4.Explosion-proof sliding door 3 passes through plate by a plurality of H profile steels 31
Band 32 is formed by connecting, and H profile steel 31 and strip 32 can play explosion-proof using no magnetic 304 stainless steel of austenite resistant to high temperature.
Adjacent H profile steel distance 300mm, the parameter of H profile steel are HW200 × 200 × 16 × 16.
Single layer sliding door 4 and explosion-proof sliding door 3 are two-way clamshell doors, due to the presence of wall bushing 7, single layer sliding door
4 and explosion-proof sliding door 3 on be provided with hole corresponding with wall bushing 7.Due to have between 2 wall bushings 7 it is certain away from
From the mode only merged by sliding door opposite direction can not protect the part between 2 casings, in the hole of explosion-proof sliding door 3
Upper and lower hinge 6 is arranged in the upper and lower edge of the corresponding part of mouth, and when explosion-proof sliding door 3 pulls open, upper and lower hinge 6 is received up and down
It rises, explosion-proof sliding door will not be stopped to slide；After explosion-proof sliding door merges, the upper and lower hinge 6 of split is simultaneously fixed, can be through walls to 2
It is protected part between casing 7.
The set-up mode at above-mentioned hole, with can accommodate wall bushing 7 pass through and wall bushing 7 do not influence sliding door pull open,
Subject to slippaging, embodiment that can be as shown in Figure 1B, the inside edge of sliding door is correspondingly arranged hole, when sliding door is two-way to be pulled open,
Hole is divided into two from centre, if Figure 1A is when sliding door is slippaged, pieces together a complete hole and just caters to 2 and wear
7 outer of wall sleeve.
Existing nanometer heat insulating material type can be used in mesoporous nano fireproof heated board 2 used by above-mentioned plugging mechanism
Such as nano-pore rolls up felt, powder, plate, coating.Current nano heat insulating material is aeroge plyability heat-barrier material and nanometer
Powder molding is compound.Substantially belong to nanoaperture mechanism, all has the disconnected heat of Superstrong heat-preserving beyond common 2-6 times of traditional material
Ability.At 300 degrees Celsius or more, temperature is higher, and there are also high than the heat insulation and preservation effect of aeroge composite insulation material by the latter
2-3 times out.It is main to utilize oxidation silicon nano power, it is equipped with special inorganic binder and a variety of thermal boundary inorganic constituents, and even mixed high temperature
Fiber and be made.20-70nm nanoscale void network structure and thermal boundary ingredient have not only prevented convective heat transfer, but also greatly drop
The low solid-state pyroconductivity and high temperature heat radiation of material makes thermal conductivity difference of the material at 200 DEG C and 800 DEG C of hot-face temperature
Down to 0.025w/m.k and 0.038w/m.k.
